Evidence for peripherally antinociceptive action of propofol in rats: behavioral and spinal neuronal responses to subcutaneous bee venom.
Sun YY, Li KC, Chen J.
In the present study, behavioral and in vivo electrophysiological methods were used to examine the peripheral effects of propofol on tonic ongoing pain-related responses produced by subcutaneous bee venom-induced inflammatory pain state. Local administration of 0.5 microg propofol produced significant suppression of the well-established ongoing pain responses in both conscious rats and dorsal horn nociceptive neurons. The locally antinociceptive action of propofol is not caused by systemic effect, because contralateral administration of the same dose of drug did not produce any effect. This result indicates that besides central actions, propofol has peripherally antinociceptive action as well.

In a previous report, subcutaneous injection of diluted bee venom (dBV) into a specific acupuncture point (Zusanli, ST36), a procedure termed apipuncture, was shown to produce an antinociceptive effect in the rat formalin pain model. However, the central antinociceptive mechanisms responsible for this effect have not been established. Traditional acupuncture-induced antinociception is considered to be mediated by activation of the descending pain inhibitory system (DPIS) including initiation of its opioidergic, adrenergic and serotonergic components. The purpose of the present study was to investigate whether the antinociceptive effect of apipuncture is also mediated by the DPIS. Behavioral experiments verified that apipuncture significantly reduces licking behavior in the late phase of formalin test in rats. This antinociceptive effect of apipuncture was not modified by intrathecal pretreatment with naltrexone (a non-selective opioid receptor antagonist), prazosin (an alpha1 adrenoceptor antagonist) or propranolol (an beta adrenoceptor antagonist). In contrast, intrathecally injected idazoxan (an alpha2 adrenoceptor antagonist) or intrathecal methysergide (a serotonin receptor antagonist) significantly reversed apipuncture-induced antinociception. These results suggest that apipuncture-induced antinociception is produced by activation of alpha2 adrenergic and serotonergic components of the DPIS.

General pharmacological profiles of bee venom and its water soluble fractions in rodent models.

Recently, the antinociceptive and anti-inflammatory efficacy of bee venom (BV, Apis mellifera) has been confirmed in rodent models of inflammation and arthritis. Interestingly, the antinociceptive and anti-inflammatory effect of whole BV can be reproduced by two water-soluble fractions of BV (>20 kDa:BVAF1 and<10 kDa: BVAF3). Based on these scientific findings, BV and its effective water-soluble fractions have been proposed as potential anti-inflammatory and antinociceptive pharmaceuticals. While BV's anti-inflammatory and antinociceptive properties have been well documented, there have been no careful studies of potential, side effects of BV and its fractions when administered in the therapeutic range (BV, 5 microgram/kg; BVAF1, 0.2 microgram/kg: BVAF3, 3 microgram/kg; subcutaneous or intradermal). Such information is critical for future clinical use of BV in humans. Because of this paucity of information, the present study was designed to determine the general pharmacological/physiological effects of BV and its fractions administration on the rodent central nervous, cardiovascular, respiratory and gastrointestinal system. Subcutaneous BV and its fractions treatment did not produce any significant effects on general physiological functions at the highest dose tested (200-fold and 100-fold doses higher than that used clinically, respectively) except writhing test. These results demonstrate that doses of BV or BV subfractions in the therapeutic range or higher can be used as safe antinociceptive and anti-inflammatory agents.

Bee venom acupoint stimulation increases Fos expression in catecholaminergic neurons in the rat brain.
Kwon YB, Han HJ, Beitz AJ, Lee JH.
Department of Veterinary Physiology, College of Veterinary Medicine and School of Agricultural Biotechnology, Seoul National University, Seoul 151-742, Korea.
Fos immunocytochemistry was combined with tyrosine hydroxylase (TH) or dopamine-beta-hydroxylase (DBH) immunolabeling to examine brainstem catecholaminergic neuronal activation resulting from bee venom (BV) stimulation of the Zusanli acupoint (ST36) in Sprague-Dawley rats. BV injection into the Zusanli acupoint caused increased Fos expression in catecholaminergic neurons located in the hypothalamic arcuate nucleus (Arc), the dorsal raphe (DR), the A5 cell group (A5) and the locus coeruleus (LC). BV acupoint stimulation significantly increased Fos-TH double-labeled neurons in the Arc, LC and DR. Fos-DBH positive neurons were also increased by BV acupoint stimulation in the LC and A5. In contrast BV stimulation of a non-acupoint only increased Fos expression and Fos-TH double-labeled neurons in the Arc. These data indicate that BV acupoint stimulation activates brainstem catecholaminergic neurons and that this activation underlies BV acupoint-induced antinociception.

Effects of intravenous Injections Paederiae and Stauntonia on spontaneous pain, hyperalgesia and inflammation induced by cutaneous chemical tissue injury in the rat.
Peng XL, Gao XL, Chen J, Huang X, Chen HS.
To study whether commercial traditional Chinese medicinal preparations Injection Paederiae (IP) or Injection Stauntonia (IS) has anti-nociceptive and/or anti-inflammatory effects, we used two persistent pain models (bee venom and formalin test) to evaluate the systemic effects of IP or IS on the chemical tissue injury-induced persistent spontaneous pain-related responses (PSPR), primary thermal/mechanical hyperalgesia and inflammation in conscious rats. Injection of bee venom (BV, 0.1 mg, 50 microl) into the plantar surface of one hind paw resulted in not only a 1-h monophasic PSPR such as flinching reflex in the injected paw and a subsequent period of 3-4 days primary heat and mechanical hyperalgesia, but also a marked sign of inflammation, including redness and swelling of the plantar surface in the injected paw. Intraplantar injection of formalin produced two phases of PSPR as reported previously. Systemic pre-treatment with three doses of IP (0.32, 1.6 and 9.0 ml/kg, 500%) or IS (0.32, 1.6 and 9.0 ml/kg, 250%) produced a dose-dependent suppression of the BV- or formalin-induced flinching reflex of 1 h time course as compared with the saline control group. Post-treatment with IP or IS 5 min after BV injection also produced a significant suppression of the flinching reflex in both BV test and formalin test respectively, as compared with the control group. However, neither pre- nor post-treatment with IP or IS produced any significantly suppressive effect on the BV-induced primary heat and mechanical hyperalgesia and inflammation. The analgesia produced by IP or IS was not mediated by the endogenous opioid receptors since naloxone, a non-selective opioid receptor antagonist, had no reversal effect on the IP and IS-produced analgesia in the BV-induced PSPR. Our present results suggest that IP or IS might prevent and relieve clinical persistent spontaneous pain, but without any anti-nociceptive and anti-inflammatory effects on the primary heat hyperalgesia, mechanical hyperalgesia, as well as inflammatory responses. The BV test might be a useful model of pain to evaluate and screen anti-nociceptive and anti-inflammatory effects of certain compounds of the Chinese medicinal herbs on the pathological origins of pain.

Differential antinociceptive effects induced by a selective cyclooxygenase-2 inhibitor (SC-236) on dorsal horn neurons and spinal withdrawal reflexes in anesthetized spinal rats.

The aim of present study was to examine the effect of a selective cyclooxygenase-2 (COX-2) inhibitor SC-236 (4 mg/kg) on the simultaneous responsiveness of spinal wide-dynamic range (WDR) neurons and single motor units (SMUs) from gastrocnemius soleus muscles to mechanical stimuli (pressure and pinch) and repeated suprathreshold (1.5xT, the intensity threshold) electrical stimuli with different frequencies (3 Hz, 20 Hz) under normal conditions and bee venom (BV, 0.2 mg/50 microl)-induced inflammation and central sensitization. During normal conditions, the responses of SMUs, but not WDR neurons, to mechanical and repeated electrical stimuli (3 Hz, wind-up) were depressed by systemic administration of SC-236 as well as its vehicle (100% dimethyl sulfoxide (DMSO)). The after-discharges of both the WDR neurons and the simultaneously recorded SMUs after electrical stimuli with 20 Hz were markedly depressed only by SC-236, indicating that the mechanisms underlying the generation of the C-fiber mediated late responses and the after-discharges may be different. The enhanced responsiveness of both WDR neurons and SMUs to mechanical pressure stimuli (allodynia) and pinch stimuli (hyperalgesia) in the BV experiments was apparently depressed by SC-236, but not its vehicle. For electrical stimulation, the enhanced late responses and after-discharges, but not early responses, of both the WDR neurons and the simultaneously recorded SMUs were markedly depressed only by SC-236. This indicates that different central pharmacological mechanisms underlie the generation of these enhanced early, late responses, and after-discharges during BV-induced inflammation. The data suggest that the COX-2 inhibitor SC-236 apparently depress the activities of both spinal cord dorsal horn neuron and spinal withdrawal reflex during BV-induced sensitization, indicating that COX-2 plays an important role in the maintenance of central sensitization.

Department of Physiology,
To investigate whether bee venom (BV) induces apoptosis, the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, terminal deoxynucleotidyl transferase- mediated dUTP nick end-labeling assay, 4,6-diamidino-2-phenylindole staining, flow cytometric analysis, and DNA fragmentation assay were performed on NCI-H1299 lung cancer cells treated with BV. Through morphological and biochemical analyses, it was demonstrated that NCI-H1299 cells treated with BV exhibit several features of apoptosis. In addition, reverse transcription-polymerase chain reaction and prostaglandin E(2) (PGE(2)) immunoassay were performed to verify whether BV possesses an inhibitory effect on the expression of cyclooxygenase (COX) and PGE(2 )synthesis. Expression of COX-2 mRNA and synthesis of PGE(2) were inhibited by BV. These results suggest the possibility that BV may exert an anti-tumor effect on human lung cancer.

Petrosaspongiolide M (PM) is an anti-inflammatory marine metabolite that displays a potent inhibitory activity toward group II and III secretory phospholipase A(2) (PLA(2)) enzymes. The details of the mechanism, which leads to a covalent adduct between PLA(2) and gamma-hydroxybutenolide-containing molecules such as PM, are still a matter of debate. In this paper the covalent binding of PM to bee venom PLA(2) has been investigated by mass spectrometry and molecular modeling. The mass increment observed for the PM-PLA(2) adduct is consistent with the formation of a Schiff base by reaction of a PLA(2) amino group with the hemiacetal function (masked aldehyde) at the C-25 atom of the PM gamma-hydroxybutenolide ring. Proteolysis of the modified PLA(2) by the endoprotease LysC followed by HPLC MS analysis allowed us to establish that the PLA(2) alpha-amino terminal group of the Ile-1 residue was the only covalent binding site for PM. The stoichiometry of the reaction between PM and PLA(2) was also monitored and results showed that even with excess inhibitor, the prevalent product is a 1:1 (inhibitor:enzyme) adduct, although a 2:1 adduct is present as a minor component. The 2:1 adduct was also characterized, which showed that the second site of reaction is located at the epsilon -amino group of the Lys-85 residue. Similar results in terms of the reaction profile, mass increments, and location of the PLA(2) binding site were obtained for manoalide, a paradigm for irreversible PLA(2) inhibitors, which suggests that the present results may be considered of more general interest within the field of anti-inflammatory sesterterpenes that contain the gamma-hydroxybutenolide pharmacophore. Finally, a 3D model, constrained by the above experimental results, was obtained by docking the inhibitor molecule into the PLA(2) binding site through AFFINITY calculations. The model provides an interesting insight into the PM-PLA(2) inhibition process and may prove useful in the design of new anti-inflammatory agents that target PLA(2) secretory enzymes.

Participation of the arachidonic acid cascade pathway in macrophage binding/uptake of oxidized low density lipoprotein.
Beppu M, Watanabe M, Sunohara M, Ohishi K, Mishima E, Kawachi H, Fujii M, Kikugawa K.
Arachidonic acid cascade inhibitors, including phospholipase A2 inhibitors, dexamethasone and quinacrine (mepacrine), cyclooxygenase inhibitors, indomethacin and aspirin, and lipoxygenase inhibitor AA861, prevented foam cell formation and cholesterol accumulation in the incubation of thioglycollate-induced mouse peritoneal macrophages with oxidized low density lipoprotein (LDL) at 37 degrees C for 24 h. These inhibitors similarly prevented foam cell formation of fibronectin- and Ca ionophore A23187-stimulated macrophages. Binding and/or uptake of Dil (1,1'-dioctadecyl-3,3,3',3'-tetramethylindocarbocyanine)-acetyl LDL by macrophages at 37 degrees C for 3h and arachidonic acid release from macrophages at 37 degrees C for 4h were inhibited by dexamethasone. Exogenously added phospholipase A2 of bee venom and Crotalus adamanteous venom increased arachidonic acid release during incubation for 2 h, and increased macrophage binding and/or uptake of Dil-acetyl LDL at 37 degrees C for 3 h, and foam cell formation at 37 degrees C for 24 h. Protein kinase inhibitors, ML-9 and staurosporine, that inhibited macrophage binding and/or uptake of Dil-acetyl LDL did not inhibit arachidonic acid release, indicating that protein phosphorylation was not involved in the arachidonic acid pathway in the macrophage scavenger receptor activation. Nordihydroguaiaretic acid that inhibited arachidonic acid release prevented binding and/or uptake of Dil-acetyl LDL. The release of arachidonic acid was not enhanced by fibronectin-stimulation, indicating that Ca influx-dependent stimulation of macrophage activity was not through the activation of phospholipase A2. These results indicate that, as well as the fibronectin-stimulated Ca influx pathway and protein phosphorylation pathway, the arachidonic acid pathway participated in the activation of macrophages to bind and take up oxidized LDL.

We recently demonstrated that bee venom (BV) injection into the Zusanli acupoint produced a significantly more potent anti-inflammatory and antinociceptive effect than injection into a non-acupoint in a Freund's adjuvant induced rheumatoid arthritis (RA) model. However, the precise BV constituents responsible for these antinociceptive and/or anti-inflammatory effects are not fully understood. In order to investigate the possible role of the soluble fraction of BV in producing the anti-arthritic actions of BV acupuncture, whole BV was extracted into two fractions according to solubility (a water soluble fraction, BVA and an ethylacetate soluble fraction, BVE) and the BVA fraction was further tested.Subcutaneous BVA injection (0.9 mg/kg/day) into the Zusanli acupoint was found to dramatically inhibit paw edema and radiological change (i.e. new bone proliferation and soft tissue swelling) caused by Freund's adjuvant injection. BVA treatment also reduced the increase in serum interleukin-6 caused by RA induction to levels observed in non-arthritic animals. In addition, BVA therapy significantly reduced arthritis-induced nociceptive behaviors (i.e. nociceptive scores for mechanical hyperalgesia and thermal hyperalgesia). Finally, BVA treatment significantly suppressed adjuvant-induced Fos expression in the lumbar spinal cord at 3 weeks post-adjuvant injection. In contrast, BVE treatment (0.05 mg/kg/day) failed to show any anti-inflammatory or antinociceptive effects on RA.The results of the present study demonstrate that BVA is the effective fraction of whole BV responsible for the antinociception and anti-inflammatory effects of BV acupuncture treatment. Thus it is recommended that this fraction of BV be used for long-term treatment of RA-induced pain and inflammation. However, further study is necessary to clarify which constituents of the BVA fraction are directly responsible for these anti-arthritis effects.

Department of Veterinary Physiology, College of Veterinary Medicine and School of Agricultural Biotechnology, Seoul National University, Suwon, Korea.
The aim of this investigation was to determine whether bee venom (BV) administered directly into an acupoint was a clinically effective and safe method for relieving the pain of patients with knee osteoarthritis (OA) as compared to traditional needle acupuncture. We evaluated the efficacy of BV acupuncture using both pain relief scores and computerized infrared thermography (IRT) following 4 weeks of BV acupuncture treatment. We observed that a significantly higher proportion of subjects receiving BV acupuncture reported substantial pain relief as compared with those receiving traditional needle acupuncture therapy. Furthermore, the IRT score was significantly improved and paralleled the level of pain relief.

Visceral antinociception produced by bee venom stimulation of the Zhongwan acupuncture point in mice: role of alpha(2) adrenoceptors.
Kwon YB, Kang MS, Han HJ, Beitz AJ, Lee JH.
Department of Veterinary Physiology, College of Veterinary Medicine and School of Agricultural Biotechnology, Seoul National University, Suwon 441-744, South Korea.
The goal of the present study was to determine whether bee venom (BV) injection into the Zhongwan acupoint (CV12), compared to injection into a non-acupoint, produced antinociception in an acetic acid-induced visceral pain model. This was accomplished by injecting BV subcutaneously into the Zhongwan acupoint or into a non-acupoint 30 min before intraperitoneal injection of acetic acid in ICR mice. BV injection into the acupoint produced a dose dependent suppression of acetic acid-induced abdominal stretches and of acetic acid-induced Fos expression in the spinal cord and the nucleus tractus solitarii. In contrast BV injection into the non-acupoint only produced antinociception at the highest dose of BV tested. Naloxone pretreatment did not alter the antinociceptive effect of BV acupoint injection on the abdominal stretch reflex. On the other hand, pretreatment with the alpha 2-adrenoceptor antagonist, yohimbine completely blocked the antinociceptive effect of BV acupoint injection. These results imply that BV acupoint stimulation can produce visceral antinociception that is associated with activation of alpha 2-adrenoceptors, but not with naloxone-sensitive opioid receptors.

From a clinical perspective, the alternative forms of acupoint stimulation including electroacupuncture, moxibustion and acupressure appear to have more potent analgesic effects than manual needle acupuncture. Bee venom (BV) injection has also been reported to produce persistent nociceptive stimulation and to cause neuronal activation in the spinal cord. In previous study, we observed that BV stimulation into acupoint, namely BV acupuncture or Apipuncture, produced more potent anti-inflammatory and antinociceptive potency in rodent arthritis model as comparing with that of non-acupoint injection. Based on previous report, we decided to further investigate that BV injection into an acupoint produces antinociception as a result of its potent chemical stimulatory effect in both abdominal stretch assay and formalin test. Different doses of BV were injected into an acupoint or a non-acupoint 30 min prior to intraplantar formalin injection or intraperitoneal acetic acid injection. Using the abdominal stretch assay, we found that the high dose of BV (1:100 diluted in 20microl saline) produced a potent antinociceptive effect irrespective of the site of BV injection. In contrast the antinociceptive effect observed in both the writhing and formalin tests following administration of a low dose of BV (1:1000 diluted in 20microl saline) was significantly different between acupoint and non-acupoint sites. BV injection into an acupoint (Zhongwan, Cv. 12) was found to produce significantly greater antinociception than non-acupoint injection (

Differential roles of spinal neurokinin 1/2 receptors in development of persistent spontaneous nociception and hyperalgesia induced by subcutaneous bee venom injection in the conscious rat.

To evaluate the roles of spinal neurokinin receptors in the development of persistent nociception and hyperalgesia to thermal and mechanical stimuli induced by subcutaneous (s.c.) bee venom injection, effects of intrathecal (i.t.) pre- or post-treatment with a non-selective antagonist of (NK1/2) receptors, [D-Arg1,D-Trp7,9,Leu11] substance P (spantide), and a selective NK3 receptor antagonist, (S)-(N)-(1-(3-(1-benzoyl-3-(3,4-dichlorophenyl) piperidin-3-yl)propyl)-4-phenylpiperidin-4-yl)-N-methyl acetamide (SR142801) were assessed in conscious rat. Injection of bee venom s.c. into the plantar surface of one hind paw resulted in a pathological pain phenomenon characterized by a 1-2 h single phase of persistent spontaneous nociceptive behaviors (continuously flinching the injected paw) and a 72-96 h profound primary thermal and mechanical hyperalgesia in the injection site and a secondary thermal hyperalgesia in the non-injected hindpaw. Pre-treatment with spantide i.t. at 0.05 microg, 0.5 microg and 5 microg produced a dose-related suppression of the bee venom-induced flinching reflex during the whole time course and the inhibitory rate was 24 +/- 12.60% (35.38 +/- 4.12 flinches/5 min, n=5), 48 +/- 6.75% (24.53 +/- 2.90 flinches/5 min, n=5) and 60 +/- 7.69% (18.88 +/- 3.58 flinches/5 min, n=5) respectively when compared with the saline control group (46.80 +/- 2.60 flinches/5 min, n=5). Post-treatment of spantide i.t. at the highest dose (5 microg) used in the present study 5 min after bee venom injection also produced a 49% suppression of the flinching reflex in the control group [post-spantide vs saline: 19.42 +/- 3.15 (n=5) vs 38.42 +/- 3.25 flinches/5 min (n=5)]. Moreover, i.t. pre-treatment with 5 microg spantide partially prevented the primary and secondary thermal hyperalgesia from occurring, while it did not show any influence on the development of primary mechanical hyperalgesia. Neither the established thermal nor mechanical hyperalgesia identified in the above sites was affected by i.t. post-treatment with the same dose of spantide 3 h after bee venom injection. Pre and post-treatment of SR142801 did not produce any significant effect on the bee venom-induced spontaneous pain and thermal and mechanical hyperalgesia. Our present result suggests that activation of spinal NK1/2 receptors is involved in both induction and maintenance of the persistent spontaneous nociception, while it is only involved in induction of the primary and secondary thermal, but not primary mechanical hyperalgesia induced by s.c. bee venom injection. The spinal NK3 receptor seems not likely to be involved in the bee venom-induced behavioral response characterized by spontaneous pain and thermal and mechanical hyperalgesia.

Bee venom pretreatment has both an antinociceptive and anti-inflammatory effect on carrageenan-induced inflammation.

Department of Veterinary Physiology, College of Veterinary Medicine, Seoul National University, Suwon, South Korea.
Although the injection of bee venom (BV) has been reported to evoke tonic pain and hyperalgesia, there is conflicting evidence in the literature indicating that BV can also exert an anti-inflammatory and antinociceptive effects on inflammation. In this regard, BV has been traditionally used in Oriental medicine to relieve pain and to treat chronic inflammatory diseases such as rheumatoid arthritis. The present study was designed to test the hypothesis that BV induces acute nociception under normal conditions, but that it can serve as a potent anti-inflammatory and antinociceptive agent in a localized inflammatory state. The experiments were designed to evaluate the effect of BV pretreatment on carrageenan (CR)-induced acute paw edema and thermal hyperalgesia. In addition, spinal cord Fos expression induced by peripheral inflammation was quantitatively analyzed. In normal animals subcutaneous BV injection into the hindlimb was found to slightly increase Fos expression in the spinal cord without producing detectable nociceptive behaviors or hyperalgesia. In contrast pretreatment with BV (0.8 mg/kg) 30 min prior to CR injection suppressed both the paw edema and thermal hyperalgesia evoked by CR. In addition, there was a positive correlation between the percent change in paw volume and the expression of Fos positive neurons in the spinal cord. These results indicate that BV pretreatment has both antinociceptive and anti-inflammatory effects in CR-induced inflammatory pain. These data also suggest that BV administration may be useful in the treatment of the pain and edema associated with chronic inflammatory diseases.

Bee venom injection into an acupuncture point reduces arthritis associated edema and nociceptive responses.

Bee venom (BV) has traditionally been used in Oriental medicine to relieve pain and to treat inflammatory diseases such as rheumatoid arthritis (RA). While several investigators have evaluated the anti-inflammatory effect of BV treatment, the anti-nociceptive effect of BV treatment on inflammatory pain has not been examined. Previous studies in experimental animals suggest that the therapeutic effect of BV on arthritis is dependent on the site of administration. Because of this potential site specificity, the present study was designed to evaluate the anti-nociceptive effect of BV injections into a specific acupoint (Zusanli) compared to a non-acupoint in an animal model of chronic arthritis.

Phospholipase A2-induced coagulation abnormalities after bee sting.
Petroianu G, Liu J, Helfrich U, Maleck W, Rufer R.
We will examine the correlation between various bee venom phospholipase A2 (PLA2) concentrations and several parameters of coagulation in human plasma in order to offer a rationale for requesting a particular laboratory coagulation test after bee sting(s). We will also evaluate in vitro the influence of clinically available drugs with a noncompetitive inhibitory effect on PLA2 on the anticoagulant effect of bee venom PLA2. Prothrombin index (PTi), partial thromboplastin time (PTT), antithrombin III (AT III), soluble fibrin monomers (SFM), the activity of coagulation factors I, II, V, and VIII, and thrombelastography (TEG) parameters (split point [Sp], reaction time [R], kinetic time [K], coagulation time [R + K], maximal amplitude [MA], and the growth angle [alpha]) were determined before and after addition of 1.4, 2.7, and 4.1 units (1, 2, and 3 microg protein respectively) of bee venom PLA2. Linear regression was used to determine the significance of the relationship between these coagulation parameters and bee venom PLA2 concentrations used. To study the influence of ketamine, lidocaine, magnesium, furosemide, and cromolyn on the anticoagulant effect of bee venom PLA2, PTi and factor II- and V-activities were measured before and after addition of 2.7 units of PLA2 and PLA2 plus one of the tested substances. Determinations of F II, PTi, F V, and F VIII showed a negative correlation to bee venom PLA2 concentration (r = -0.88, -0.86, -0.81, and -0.79 respectively). A positive correlation was found for PTT (r = 0.69). FII- activity and PTi correlated better with bee venom PLA2 concentration than other parameters. F I, AT III, and SFM showed no changes. Whereas Sp, R, and K were prolonged by bee venom PLA2 and a was reduced, there was no correlation to the PLA2 concentration. Addition of none of the 5 substances could correct the effects of bee venom PLA2 on the coagulation. In a patient with toxic reaction or a severe anaphylactic reaction after bee sting(s) we suggest determinations of FII and/or PTi. This will allow a quick and economical assessment of coagulation abnormalities after bee sting(s). Noncompetitive PLA2-inhibitors (ketamine, lidocaine, magnesium, furosemide, and cromolyn) are unable to correct in vitro the anticoagulant effect of bee venom PLA2. They cannot be recommended at this stage for this purpose. Further investigations with competitive PLA2-inhibitors are warranted.

Effects of petrosaspongiolide M, a novel phospholipase A2 inhibitor, on acute and chronic inflammation.
Garcia-Pastor P, Randazzo A, Gomez-Paloma L, Alcaraz MJ, Paya M.
Departamento de Farmacologia, Universidad de Valencia, Facultad de Farmacia, Valencia, Spain.
The marine product petrosaspongiolide M is a novel inhibitor of phospholipase A2 (PLA2), showing selectivity for secretory PLA2 versus cytosolic PLA2, with a potency on the human synovial enzyme (group II) similar to that of manoalide. This compound was more potent than manoalide on bee venom PLA2 (group III) and had no effect on group I enzymes (Naja naja and porcine pancreatic PLA2). Inhibition of PLA2 was also observed in vivo in the zymosan-injected rat air pouch, on the secretory enzyme accumulated in the pouch exudate. Petrosaspongiolide M decreased carrageenan paw edema in mice after the oral administration of 5, 10, or 20 mg/kg. This marine metabolite (0.01-1.0 micromol/pouch) induced a dose-dependent reduction in the levels of prostaglandin (PG)E2, leukotriene B4, and tumor necrosis factor-alpha in the mouse air pouch injected with zymosan 4 h after the stimulus. It also had a weaker effect on cell migration. The inflammatory response of adjuvant arthritis was reduced by petrosaspongiolide M, which also inhibited leukotriene B4 levels in serum and PGE2 levels in paw homogenates. In contrast with indomethacin, this marine compound did not reduce PGE2 levels in stomach homogenates. Petrosaspongiolide M is a new inhibitor of secretory PLA2 in vitro and in vivo, with anti-inflammatory properties in acute and chronic inflammation.

The bee venom test: a new tonic-pain test.
Lariviere WR, Melzack R.
Department of Psychology, McGill University, Montreal, Quebec, Canada.
The present study describes a new test of tonic pain to be used as an animal model of persistent pain. First, pain responses and edema produced by subcutaneous injection of increasing doses of honey bee venom into the hind paw of the rat were quantified. Second, the effect of morphine and aspirin on the pain responses was investigated. Finally, the response to concurrent injections of bee venom and formalin was examined. Subcutaneous injection of bee venom produced local inflammation, tonic-pain responses lasting from 10 min to more than 1 h, and marked edema lasting from 3 h to more than 48 h. Increasing doses of bee venom produced higher mean pain scores and increased durations of responding. The time course of the edema did not follow the time course of the pain responses. Analgesia was produced by morphine and aspirin, indicating that the bee venom test can be used to test analgesic drugs. Concurrent administration of bee venom and formalin produced pain responses similar to formalin alone, with a less profound interphase depression and a longer duration. The data suggest that the bee venom test is a valid animal model of experimental tonic pain.

Effects of marine 2-polyprenyl-1,4-hydroquinones on phospholipase A2 activity and some inflammatory responses.
Gil B, Sanz MJ, Terencio MC, De Giulio A, De Rosa S, Alcaraz MJ, Paya M.
Department of Pharmacology, University of Valencia, Faculty of Pharmacy, Spain.
Three 2-polyprenyl-1,4-hydroquinone derivatives (2-heptaprenyl-1,4-hydroquinone: IS1, 2-octaprenyl-1,4-hydroquinone: IS2 and 2-[24-hydroxy]-octaprenyl-1,4-hydroquinone: IS3) isolated from the Mediterranean sponge Ircinia spinosula, were evaluated for effects on phospholipase A2 activity of different origin (Naja naja venom, human recombinant synovial fluid and bee venom), as well as on human neutrophil function and mouse ear oedema induced by 12-O-tetradecanoylphorbol 13-acetate (TPA). IS1 interacted minimally with these responses. In contrast, IS2 and IS3 inhibited human recombinant synovial phospholipase A2 in a concentration-dependent manner, with minor effects on the rest of the enzymes. Both compounds slightly affected superoxide generation and degranulation in human neutrophils, whereas they decreased thromboxane B2 and leukotriene B4 synthesis and release in a mixed suspension of human platelets and neutrophils stimulated by ionophore A23187, with IC50 values in the microM range. IS3 was the most effective inhibitor of the synthesis of thromboxane B2 by human platelet microsomes and of leukotriene B4 by high speed supernatants from human neutrophils. IS2 and IS3 showed topical anti-inflammatory activity against the TPA-induced ear inflammation in mice, with similar effects on oedema and a higher inhibition of IS3 on leukocyte migration, estimated as myeloperoxidase activity in supernatants of ear homogenates. Some structure-activity relationships were established since differences in the prenylated chain attached to the hydroquinone moiety result in important modifications of these inflammatory responses.

Melittin increases AMPA receptor affinity in rat brain synaptoneurosomes.
Bernard J, Chabot C, Gagne J, Baudry M, Massicotte G.
Universite du Quebec a Trois-Rivieres, Departement de Chimie-Biologie, Canada.
Recent experimental evidence suggests that phospholipase-induced changes in binding properties of the alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionate (AMPA) subtype of glutamate receptors account for the increase in synaptic response observed in long-term potentiation (LTP). In the present study, we report that treatment of rat telencephalic synaptoneurosomes with the bee venom peptide melittin, a potent activator of endogenous phospholipases, increased [3H]AMPA binding to the AMPA receptor. The action of melittin was concentration-dependent (EC50 value = 10 micrograms/ml) and did not require the presence of extracellular calcium. Saturation kinetic experiments revealed that the increase in [3H]AMPA binding produced by melittin was due to an enhancement in the affinity of the AMPA receptor, an effect markedly reduced by the phospholipase A2 (PLA2) inhibitor bromophenacyl bromide (BPB). In contrast to BPB, inhibitors of cyclooxygenase and lipoxygenase pathways of arachidonic acid metabolism did not interfere with the melittin-induced increase in [3H]AMPA binding. In neonatal synaptoneurosomes, the effect of melittin on [3H]AMPA binding was significantly reduced when compared to adult synaptoneurosomes, an effect which is consistent with the observation that LTP is not present in very young animals. The results indicate that activation of endogenous phospholipases may be an important mechanism in the regulation of AMPA receptor properties in LTP.

Groups I, II and III extracellular phospholipases A2: selective inhibition of group II enzymes by indomethacin but not other NSAIDs.
Lobo IB, Hoult JR.
Pharmacology Group, King's College,
The three types (groups I, II and III) of stable extracellular 14 kDa phospholipase A2 enzymes differ in their primary amino acid sequences and their properties. It may thus be possible to design low-molecular weight inhibitors targeted to the secretory form of mammalian PLA2. This enzyme has been implicated in inflammatory disorders. We have studied the inhibition of four distinct PLA2 enzymes by a range of NSAIDs, using 3H-oleate release from prelabelled membranes of E. coli for assay. The enzymes used were cobra venom PLA2 (Naja naja, a group I enzyme), bee venom PLA2 (Apis mellifera, group III), recombinant human synovial PLA2 (group II) and rat peritoneal PLA2 (group II). Under the conditions of the 3H-oleate E. coli assay,

Oncology and Inflammation Section, Lederle Labs American Cyanamid Co., Pearl River, New York 10965.
Several 1-alkyl ether lipids were studied for their ability to inhibit PLA2 and antagonize PAF responses. Studies with synthetic micellar substrate (1-stearyl-2-arachidonyl phosphocholine), at concentrations ranging from 0.02 to 1000 microM, demonstrate that CL 118326 inhibits porcine pancreatic PLA2 in vitro. As the substrate concentration increases, there is a dose-dependent increase in the IC50 value (IC50 ranges: 1.6-84.6 micrograms/ml or 2.6-137 microM). CL 118326 inhibits mammalian pancreatic PLA2, but not snake or bee venom PLA2. CL 118326 inhibits thrombin (IC50 = 7.9 microM), but not Na arachidonate- (IC50 > 100 microM) induced platelet aggregation, indicative of inhibition of cellular PLA2. CL 118326 inhibits other PLA2-dependent processes such as antigen-induced leukotriene (LTC4) release (IC50 = 2.3 micrograms/ml or 3.8 microM) and histamine release (IC50 = 1.4 micrograms/ml or 2.2 microM) in basophil-enriched WBCs. Intradermal coinjection of CL 118326 (10 micrograms) with PLA2 into guinea pig skin inhibits pancreatic PLA2-induced increase in vascular permeability and leakage, but not snake or bee venom PLA2-induced leakage. CL 118326 shows no PAF-like agonist activity in stimulating rabbit platelet-rich plasma. It inhibits PAF-induced aggregation (IC50 = 5.8 microM), but not ADP-induced aggregation. CL 118326 has greater efficacy as a PLA2 inhibitor than as a PAF antagonist since the IC50-substrate concentration ratio for PLA2 inhibition is < or = 1.0 at substrate concentrations of 10-1000 microM while the IC50-agonist ratio for PAF antagonism is > 100. Results for four other compounds related to CL 118326 are also presented.

[Comparison of anti-inflammatory, analgesic activities, anaphylactogenicity and acute toxicity between bee venom and its peptides]
[Article in Chinese]
Chen CY, Chen WX, Sun X.
Nanjing Institute of Biochemical Pharmacy.
Bee venom 1.0-2.0 mg/kg and bee venom peptides 1.0-2.0 mg/kg inhibited several inflammatory processes, such as ear swelling induced by xylene in mice, edema produced by injecting 1% carrageenin 0.1 ml beneath the plantar surface of hind paw in rats and showed a marked analgesic action induced by the hot plate and potassium antimony tartrate. Bee venom peptides had a markedly more effective action as compared with bee venom itself. The anaphylactogenicity of bee venom peptides was apparently milder than that of bee venom. The LD50 of bee venom ip in mice and bee venom peptides was 7.4 mg/kg and 7.9 mg/kg respectively.

Anti-inflammatory effect of gangliosides in the rat hindpaw edema test.
Correa SG, Bianco ID, Riera CM, Fidelio GD.
Departamento de Bioquimica Clinica, CIOUIBIC, Facultad de Ciencias Quimicas, Cordoba, Argentina.
The influence of total brain gangliosides on acute inflammation was investigated using the rat hind paw edema test. Total gangliosides (10 micrograms/paw) inhibited the edema produced by the injection of bee venom phospholipase A2 (5 micrograms/paw) when the lipids were co-injected or injected 15 min before the phospholipase A2. Sulphatide (10 micrograms/paw) did not inhibit the edema but potentiated it. Gangliosides (40 micrograms/paw) inhibited the edema induced by carrageenin 1% when they were injected 1 h before the agent. However, gangliosides (up to 200 micrograms/paw) failed to inhibit the dextran-induced edema. The edema test was also used to investigate the effect of gangliosides on the production of mediators of inflammation by peritoneal adherent macrophages. Gangliosides inhibited the production of mediators of inflammation only when they were incubated with these cells before the stimulation with phospholipase A2 or carrageenin. Gangliosides did not inhibit the production of mediators of inflammation when arachidonic acid was added to the cells. These results suggest that the anti-inflammatory effect observed with gangliosides is mediated by inhibition at or before endogenous phospholipase activity.

Inactivation of phospholipase A2 by manoalide. Localization of the manoalide binding site on bee venom phospholipase A2.
Glaser KB, Vedvick TS, Jacobs RS.
Department of Biological Sciences, University of California, Santa Barbara 93106.
The marine natural product manoalide (MLD), a potent inhibitor of phospholipases, completely inactivates bee venom phospholipase A2 (PLA2) by an irreversible mechanism. It has been proposed [K. B. Glaser and R. S. Jacobs, Biochem. Pharmac. 36, 2079 (1987)] that the reaction of MLD with PLA2 may involve the selective reactivity of MLD to a peptide sequence, possibly a Lys-X-X-Lys peptide. Localization of the MLD binding site on bee venom PLA2 demonstrated that upon MLD modification of bee venom PLA2 the only change in amino acid content was an apparent loss of Lys, corresponding to approximately three of the eleven

Differential effects of manoalide on secreted and intracellular phospholipases.
Bennett CF, Mong S, Clarke MA, Kruse LI, Crooke ST.
Manoalide, a novel nonsteroidal sesterterpenoid, is a potent inhibitor of phospholipase A2 isolated from bee and cobra venoms. This report compares the inhibition by manoalide of phospholipase A2 in crude cytosol fractions from four mammalian tissues with that of four purified extracellular phospholipase A2's. Phospholipase A2 isolated from bee venom (Apis mellifera) was the most sensitive to inactivation by manoalide (IC50 approximately equal to 0.12 microM). Extracellular phospholipase A2 from rattlesnake and cobra venom was intermediate in sensitivity to manoalide (IC50 values of 0.7 and 1.9 microM respectively). Porcine pancreatic phospholipase A2 was relatively resistant to inactivation by manoalide (IC50 approximately equal to 30 microM). The phospholipase A2 assayed in crude cytosol fractions from four mammalian tissues exhibited IC50 values of 30 microM or greater. Cytosolic proteins as well as bovine serum albumin and poly-L-lysine (Mr = 57,000) protected purified bee venom phospholipase A2 from inactivation by manoalide. In contrast, amino acids such as lysine and alanine failed to protect the purified enzyme from inactivation. Proteins and certain amino acids, such as lysine, formed a chromogenic product when incubated with manoalide. These data suggest that lysine is capable of reacting with manoalide, but only when it is present in macromolecules is it capable of protecting phospholipase A2 from inactivation by manoalide. Because cellular proteins protect PLA2 from inactivation by manoalide, high concentrations of manoalide must be applied topically to produce statistically significant inactivation of intracellular phospholipase A2. Finally, a chemical model is presented which explains the formation of a chromogenic product when manoalide is incubated with proteins and amino acids.

Further investigation on the antiinflammatory properties of adolapin--bee venom polypeptide.
Koburova KL, Michailova SG, Shkenderov SV.
Adolapin is a basic polypeptide (M. W. 11500) isolated from bee venom. It showed marked antiinflammatory and analgetic properties and inhibited cyclooxygenase. It was found that adolapin inhibited also the activity of bee venom phospholipase A2 (7 nmole/ml producing about 80% inhibition of 2.5 nmole/ml phospholipase). In addition it inhibited the lipoxygenase from human platelets (4.5 nmole/ml inhibited about 80% of the activity of 0.8 mg protein/ml). Adolapin (20 micrograms/kg) caused an elevation of c-GMP level in rat spleen and brain as well as a decrease of c-AMP in rat spleen. Adolapin was tested by the "tail flick" method which allowed the demonstration of its analgetic action. The partial inhibition of the analgetic effect of adolapin induced by naloxon, proved the participation of a central mechanism of action. Similar to other nonsteroid analgetics, adolapin displayed antipyretic effect (40 micrograms/kg caused an inhibition of the mean temperature rise about 62%.

Adolapin--a newly isolated analgetic and anti-inflammatory polypeptide from bee venom.
Shkenderov S, Koburova K.
Adolapin was isolated by a two-step procedure: gel filtration and chromatography on CM cellulose. The molecular mass of the polypeptide as determined by SDS electrophoresis and amino acid composition proved to be 11500 and 11092 respectively. Adolapin exhibited a potent analgesic effect demonstrated by the "writhing" test (ED50-0,016mg/kg) and by the Randall-Sellito's test (ED50-0,013 mg/kg). The anti-inflammatory activity of adolapin was most marked with regard to carrageenin, prostaglandin and adjuvant rat hind paw edemas and adjuvant polyarthritis. The adolapin effects are presumably due to its capacity to inhibit the prostaglandin synthase system, following a biphasic dose-response relationship. It is likely that central mechanisms are also involved in the analgetic action of adolapin.

Apamin, a nonspecific antagonist of smooth muscle relaxants.
Muller MJ, Baer HP.
Apamin, a peptide of bee venom, was shown to inhibit the relaxant responses of guinea-pig taenia caeci to ATP, noradrenaline, adenosine and, less effectively, to stimulation of noradrenergic inhibitory nerves. Thus apamin acts nonspecifically and, contrary to the suggestion of Vladimirova and Shuba (1978), the fact that inhibitory responses due to nerve stimulation and ATP are blocked by the toxin does not allow conclusions as to the possible transmitter role of ATP in these nerves.
