  • In the present study, I have investigated the bee venom (BV) and melittin (a major component of BV) -mediated anti-proliferative effects, and defined its mechanisms of action in cultured rat aortic vascular smooth muscle cells (VSMCs). BV and melittin $(0.4{\sim}0.8\;{\mu}g/ml)$ effectively inhibited 50 ng/ml platelet derived growth factor BB (PDGF-BB)-induced VSMCs proliferations. The regulation of apoptosis has attracted much attention as a possible means of eliminating excessively proliferating VSMCs. In the present study, the treatment of BV and melittin strongly induced apoptosis of VSMCs. I examined the effects on $NF-{\kappa}B$ activation to investigate a possible mechanism for anti-proliferative effects of BV and melittin, the PDGF-BB-induced $I{\kappa}B{\alpha}$ phosphorylation and its degradation were potently inhibited by melittin, and DNA binding activity and nuclear translocation of $NF-{\kappa}B$ p50 subunit in response to the action of PDGF-BB were potently attenuated by melittin. In further investigations, melittin markedly inhibited the PDGF-BB-induced phosphorylation of Akt but not ERK1/2, upstream signals of $NF-{\kappa}B$. Treatment of melittin also potently induced pro-apoptotic protein p53, Bax, and caspase-3 expression, but decreased anti-apoptotic protein Bcl-2 expression. These results suggest that the anti-proliferative effects of BV and melittin in VSMCs through induction of apoptosis via suppressions of $NF-{\kappa}B$ and Akt activation, and enhancement of apoptotic signal pathway. Based on these results, BV acupuncture can be a candidate as a therapeutic method for restenosis and atherosclerosis.

  • Bee venom (Apis mellifera L. BV) has been used as a cosmetic ingredient for anti-ageing, anti-inflammatory and antibacterial functions. The aim of this study was to evaluate the acute toxicity after a single dermal administration of BV, BV was administered to 2 groups of Sprague-Dawley (SD) male and female rats (5 animals/group) at doses of 0 and 1,500 mg/kg body weight (BW). Mortality, clinical signs, body weight changes and gross findings were continually monitored for 15 days following the single dose. There were no unscheduled deaths in any groups during the study period. No BV related clinical signs and body weight changes were observed in any groups during the study period. There were no abnormal gross findings at necropsy on day 15 after the treatment. On the basis of the above results, it was concluded that there were no treatment-related effect on mortality, clinical signs, body weight changes and gross findings in SD rats treated with a single dermal dose of BV at dose of 1,500 mg/kg BW. Therefore, the approximate lethal dose of BV was considered to be over 1,500 mg/kg/day for both sexes of rats. BV may provide a developmental basis for a cosmetic ingredient or external application for topical uses.

  • Bee venom (BV), well known as a traditional Oriental medicine, has been widely used in the treatment of some immune-related diseases. However, the anti-allergic effect of BV have not been reported. In this study, we investigated the antiallergic effect of BV on triphasic cutaneous reaction (TpCR) and passive cutaneous anaphylaxis (PCA). Our results indicated that BV suppress ear swelling and vascular permeability on IgE mediated type I hypersensitivity response. Increase in ear thickness was significantly inhibited by BV in this model. BV also blocked the infiltration of immune cells into the ear. Moreover, BV suppressed expression of HDAC3, Tryptase, MCP-1 in ear tissue. These results demonstrated that BV has a suppressive effect on allergic reaction.

  • Objectives: Medicinal plants are vital sources of bioactive compounds that are useful for the treatment of patients with snake bites or are indirectly applicable for boosting the effects of conventional serum therapy. These plants are being used traditionally by local healers and tribes for the treatment of patients with snake bites and therefore can be used as an alternative against snake envenomation. Scientifically, using the secondary metabolites of plants to neutralize venom enzymes has an extra benefit of being based on traditional knowledge; also, the use of such metabolites for the treatment of patients with snake bites is cheaper and the treatment can be started sooner. Methods: All the available information on various secondary metabolites exhibiting venom neutralizing ability were collected via electronic search (using Google books, Pubmed, SciFinder, Scirus, Google Scholar, and Web of Science) and articles of peer-reviewed journals. Results:Recent interest in different plant has focused on isolating and identifying of different phytoconstituents that exhibit Phospholipase A2 activity and other venom enzyme neutralizing ability. In this support convincing evidence in experimental animal models are available. Conclusion: Secondary metabolites are naturally present, have no side effect, are stable for a long time, can be easily stored, and can neutralize a wide range of snake enzymes, such as phospholipase A2, hyaluronidase, protease, L-amino acid oxidase, 5'nucleotidase, etc. The current review presents a compilation of important plant secondary metabolites that are effective against snake venom due to enzyme neutralization.

  • Bee Venom (BV) has been treated in inflammatory diseases such as rheumatoid arthritis (RA). Bee venom contains several biologically active non-peptide substances as well as two major known peptides; the hemolytic peptide melittin (50%) and the neurotoxic peptide apamin, and a number of minor peptides. Previous our study showed that BV blocked LPS and SNP-induced production of NO and PG through inactivation of NF-kB which regulates expression of COX-2 and iNOS. (omitted)

  • Background: Tiryaq-e-arba is a polyherbal Unani antidote/antivenom formulation used in the management of poisoning due to snake bite, scorpion bite as well as in cold poisons since time immemorial. Objectives: Tiryaq-e-arba was not evaluated scientifically before this study carried out, therefore it was studied for antivenom activity by testing on plasma fibrinogen level in Russell's Viper envenomation in rabbits. Material &Methods: The anti-venom activity of the test drug was studied by observing its effect on plasma fibrinogen level in Russell's Viper envenomation in rabbits by the method of Netelson. Results: The plasma fibrinogen level was found to be 171±665.04 mg/100 ml of blood, 36.18±1.12 mg/100 ml of blood, 33.14±0.52 mg/100 ml of blood and 17.9±1.65 mg/100 ml of blood at 0, 1, 3 and 6 hours respectively in control animals while in the test animal it was found to be 157.13±3.44 mg/100 ml of blood, 41.13±2.69 mg/100 ml of blood, 62.09±1.65 mg/100 ml of blood and 54.39±0.73 mg/100 ml of blood respectively. The test showed that though the plasma fibrinogen level in the test lower at 0 hour but it was greater in the control animals at 1, 3 and 6 hours. The increase in plasma fibrinogen level in the test animals at 3 and 6 hours was statistically significant (P<0.001). Conclusions: The finding of the present study was that Tiryaq-e-arba possesses antivenom activity which scientifically support the Unani claim that it is Dafe-Sumoom-al-Hevan (Antivenom or Antidote) and the use of this preparation in corresponding diseases.

  • Background: Atopic dermatitis (AD) is a chronic inflammatory condition which can be studied using phthalic anhydride (PA) to induce AD. Anti-inflammatory properties of bee venom (BV) wereinvestigated to determine whether it may be a useful treatment for AD. Methods: AD was induced by applying to pical PA to 8-week-old HR-1 mice (N = 50), then treating with (0.1, 0.25, and 0.5 ㎍) or without topical BV. Body weight, ear thickness histology, enzyme-linked immune sorbent assay (serum IgE concentrations), Western blot analysis [inducible nitric oxide synthase, cyclooxygenase-2, IκB-α, phospho-IκB-α, c-Jun N-terminal kinase (JNK), phospho-JNK, p38, phospho-p38, extra cellular signal-regulated kinase (ERK), and phospho-ERK], and the pull down assay for immunoblotting (p50), were used to measure inflammatory mediators. Results: PA + BV (0.1, 0.25, and 0.5 ㎍) significantly decreased ear thickness without altering body weight. IgE concentrations decreased in the PA + BV (0.5 ㎍)-treated groups compared with PAtreatment. Tumor necrosis factor-α, interleukin-1β, inducible nitric oxide synthase, cyclooxygenase-2, phospho-IκB-α, phospho-JNK, p38, phospho-p38, and phospho-ERK, all decreased following treatment with PA + BV compared with the PA-treatment alone. p50 was upregulated in the PA + BV-treated groups compared with the PA-treated group. Furthermore, the number of mast cells decreased in the PA + BV-treated groups compared with the PA-treated group. Epidermal thickness was significantly lower in the PA + BV-treated group compared with PA treatment alone. Conclusion: BV maybe a useful anti-inflammatory treatment for AD.

  • Background: Although bee venom (BV) has clinical benefits in osteoarthritis and rheumatoid arthritis, it has not been tested as treatment for gouty arthritis. Moreover, in vitro, BV has been proven to exhibit anti-inflammatory and positive effects on osteoarthritis, but only limited evidence can confirm its beneficial effects on gout. Thus, this study aims to assess the anti-inflammatory effects of BV on monosodium urate (MSU)-induced THP-1 monocytes. Methods: THP-1 monocytes were differentiated into mature macrophages using phorbol 12-myristate 13-acetate (PMA) and pretreated for 6 hours with BV and a Caspase-1 inhibitor in a physiologically achievable range of concentrations (BV, 0.1-1 ㎍/mL; Caspase-1 inhibitor, 1-10 μM), followed by MSU crystal stimulation for 24 hours. The secretions of interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), IL-6, IL-8, cyclooxygenase-2 (COX-2), prostaglandin E2 (PGE2), and nitric oxide (NO) were increased in the MSU crystal-stimulated THP-1 cells. Results: Caspase-1 inhibitors suppressed the production of all mediators in a dose-dependent manner. BV worked on equal terms with Caspase-1 inhibitors and showed more satisfactory effects on TNF-α, PGE2, COX-2, and inducible nitric oxide synthase (iNOS). Moreover, the western blot analysis revealed that BV regulated the transcriptional levels of these mediators via the suppression of extracellular signal-regulated kinase (ERK) pathway activation. Conclusion: The results of the present study clearly suggest that BV inhibits MSU-induced inflammation in vitro, suggesting a possible role for BV in gout treatment.
