  • Objectives : I investigated whether snake venom can synergistically strengthen the cytotoxic effects of NK-92 cells, and enhance the inhibition of the growth of lung cancer cells including NCI-H358 through the induction of death receptor dependent extrinsic apoptosis. Methods : Snake venom toxin inhibited cell growth of NCI-H358 Cells and exerted non influence on NK-92 cell viability. Moreover, when they were co-cultured with NK cells and concomitantly treated with $4{\mu}g/m{\ell}$ of snake venom toxin, more influence was exerted on the inhibition of growth of NCI-H358 cells than BV or NK cell co-culture alone. Results : The expression of Fas, TNFR2 and DR3 and in NCI-H358 lung cancer cells was significantly increased by co-culture of NK-92 cells and treatment of $4{\mu}g/m{\ell}$ of snake venom toxin, compared to co-culture of NK-92 cells alone. Coincidentally, Bax, caspase-3 and caspase-8 - expressions of pro-apoptotic proteins in the extrinsic apoptosis pathway, demonstrated significant increase. However, in anti-apoptotic NF-${\kappa}B$ activities, activity of the signal molecule was significantly decreased by co-culture of NK-92 cells and treatment of $4{\mu}g/m{\ell}$ of snake venom toxin, compared to co-culture of NK-92 cells or snake venom toxin treated by NCIH358 alone. Meanwhile, in terms of NO generation, there is a significant increase, in co-culture of NK-92 cells with NCI-H358 cells as well as the co-culture of NK-92 cells and concomitant treatment of $4{\mu}g/m{\ell}$ of snake venom toxin. However, no synergistic increase of NO generation was shown in co-culture of NK-92 cells and treatment of $4{\mu}g/m{\ell}$ of snake venom toxin, compared to co-culture of NK-92 cells with NCI-H358 cells. Conclusion : Consequently, this data provides that snake venom toxin could be useful candidate compounds to suppress lung cancer growth along with the cytotoxic effect of NK-92 cells through extrinsic apoptosis.

  • Objectives: Snake venom is a complex mixture of various pharmacologically active substances, such as small proteins, peptides, and organic and mineral components. This paper aims to identify and analyse the proteins in common venomous snakes, such as Gloydius blomhoffii (G. blomhoffii) and Agkistrodon acutus (A. acutus), in Korea. Methods: We used mass spectrometry, electrophoresis, N-terminal sequencing and in-gel digestion to analyse the proteins in these two snake venoms. Results: We identified eight proteins in G. blomhoffii venom and four proteins in A. acutus venom. The proteins detected in G. blomhoffii and A. acutus venoms were phospholipase A2, snake venom metalloproteinase and cysteine-rich secretory protein. Snake C-type lectin (snaclec) was unique to A. acutus venom. Conclusion: These data will contribute to the current knowledge of proteins present in the venoms of viper snakes and provide useful information for investigating their therapeutic potential.

  • Objectives : The purpose of this research was to investigate the cytotoxic effect of Natural Killer(NK)-92 cell and Snake Venom, and to elucidate its mechanism on human lung carcinoma cell A549. Methods : In order to figure out whether Snake Venom enhances the cytotoxic effect of NK-92 cell in A549 cell, Cell Viability Assay was conducted. Also, in order to observe the changes of Caspase-3 and Caspase-8, both of which are proteinases that advance apoptosis, and the changes of TNRF and DR3, which are Death Receptors of the extrinsic pathway of apoptosis, Western Blot Analysis was conducted. By conducting RT-PCR analysis, we have tried to confirm Perforin, Granzyme B, and GADPH, all of which are cytotoxic-related proteins. Lastly, in order to observe the effect of Snake Venom on NO formation within human lung carcinoma cells, NO determination was conducted. Results : 1. After conducting Cell Viability Assay, Snake Venom enhanced the cytotoxic effect of NK-92 cell and inhibited the growth of A549. 2. Western Blot Analysis caused proteinases Caspase-3 and Caspase-8, which advance apoptosis, to increase in the combined treatment group, but not in treatment groups that focused only on either Snake Venom or NK-92 cell in A549 lung carcinoma cells. 3. Western Blot Analysis caused an expression of TNFR2 and DR3, both of which are Death Receptors of the apoptosis extrinsic pathway, in the combined treatment group, but not intreatment groups that focused only on either Snake Venom or NK-92 cell in A549 human lung carcinoma cells. 4. After conducting NO determination, NO formation within A549 cell showed no significant changes in both treatment groups that focused NK-92 cell and combined treatment group. 5. After conducting RT-PCR, the expression of Granzyme B and Perforin, which are cytotoxic-related proteins within A549 human lung carcinoma cells, showed growth in the combined treatment group, but not the treatment group that focused only on NK-92 cell. Conclusion : It has been indicated that, when it comes to the A549 cell, Snake Venom enhances the increase of Death Receptor expression and continuous apoptosis reaction, leading to the enhancement of the cancer cell cytotoxic effect of the NK-92 cell. It is expected that Snake Venom can be used with the NK-92 cell for further lung cancer treatment.

  • 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.

  • The antisnake venom activity of Clerodendrum viscosum Vent. (Fam. Verbenaceae), a plant traditionally used in India for the treatment of snake bite was evaluated by in vitro and in vivo methods. While in vitro studies were performed using human blood, in vivo studies were carried out using mice administered three different i.p doses of the extract, 5 min before the administration of Naja naja snake venom. The results of the in vitro studies showed that the extract probably interacts with but does not stabilize membrane protein. In the in vivo studies the extract showed significant antisnake venom activity, which may be attributed to its possible interference with the acetylcholine receptor sites. Hence the present investigation justifies the traditional use of Clerodendrum viscosum (C. viscosum) as antisnake venom.

  • Objectives: Fibrinolytic enzyme preparations were isolated from the snake venom of Macrovipera lebetica turanica in this study. Methods: The purity of the preparations was determined using SDS-PAGE and the enzymic characteristics of the purified fibrinolytic enzyme were determined. Results: 1. All of the two preparations with fibrinolytic activity obtained from the snake venom of M. l. turanicat contained the major polypeptide with the molecular weight of 27,500. One of the preparation showed purified fibrinolytic enzyme. 2. The purified fibrinolytic enzyme hydrolyzed ${\alpha}$-chain of fibrinogen faster than ${\beta}$-chain but not ${\gamma}$-chain. 3. The fibrinolytic activity was inhibited completely by EDTA, EGTA, 1,10-phenanthroline, and dithiothreitol. 4. The fibrinolytic activity was inhibited completely by calcium chloride, iron(III) chloride, mercuric chloride, and cobalt (II) chloride. 5. The fibrinolysis zone formed after addition of zinc sulfate was smaller but clearer than the control. Conclusions: These results suggested that the fibrinolytic enzyme purifed from the snake venom of M. l turanica was a metalloprotease containing dithiol group.

  • Snakebite is a severe medical, economic, and social problem across the world, mostly in the tropical and subtropical area. These regions of the globe have typical of the world's venomous snakes present where access to prompt treatment is limited or not available. Snake venom is a complex mixture of toxin proteins like neurotoxin and cardiotoxin, and other enzymes like phospholipase A2 (PLA2), haemorrhaging, transaminase, hyaluronidase, phosphodiesterase, acetylcholinesterase, cytolytic and necrotic toxins. Snake venom shows a wide range of biological effects like anticoagulation or platelet aggregation, hemolysis, hypotension and edema. Phospholipase A2 is the principal constituent of snake venom; it catalyzes the hydrolysis of the sn-2 position of membrane glycerophospholipids to liberate arachidonic acid, which is the precursor of eicosanoids including prostaglandins and leukotrienes. The information regarding the structure and function of the phospholipase A2 enzyme may help in treating the snakebite victims. This review article constitutes a brief description of the structure, types, mechanism occurrence, and tests of phospholipase A2 and role of components of medicinal plants used to inhibit phospholipase A2.

  • In the present study, we investigated anti-cancer effect of snake venom activated NK cells (NK-92MI) in lung cancer cell lines. We used snake venom ($4{\mu}g/ml$) treated NK-92MI cells to co-culture with lung cancer cells. There was a further decrease in cancer cell growth up to 65% and 70% in A549 and NCI-H460 cell lines respectively, whereas 30-40% was decreased in cancer cell growth by snake venom or NK-92MI alone treatment. We further found that the expression of various apoptotic proteins such as that Bax, and cleaved caspase-3 as well as the expression of various death receptor proteins like DR3, DR4 and Fas was also further increased. Moreover, consistent with cancer cell growth inhibition, the DNA binding activity of NF-${\kappa}B$ was also further inhibited after treatment of snake venom activated NK-92MI cells. Thus, the present data showed that activated NK cells could further inhibit lung cancer cell growth.
