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.

This study was carried out to invastigate the researches of Snake Venom and snakes which used in treatment 1. The fist literature that used the snake for treatment is Shin Nong Ben Cao Jing 2. Composition of Snake Venom is consist of Enzymatic proteins ; Phospholipase A(A1-2), Protease, L-amino acid oxidase etc, and Non-enzymatic proteins ; Crotamine(Cytolysin), Proteolytic factor(Hematoxin), Crotoxin(Neurotoxin) etc. 3. Main toxins in Snake Venom are Hematoxin, Cytolysin, Neurotoxin and Cardiotoxin. Lethal dose 50 value of Agkistrodon brevicaudus is $45.87{\mu}g$/18g, Agkistrodon saxatilis is $10.28{\mu}g$/18g, Agkistrodon ussuriensis is $8.68{\mu}g$/18g, therefore Agkistrodon ussuriensis has strongist Snake Venom of all in Korea. 4. Pharmacological actions of Snake Venom are anticoagulation, thrombolytic function, hypotensor etc. 5. Systemic syndromes and signs after snakebite are Dizziness(25.7%), Vomitting(23.1%), Fever(22%), Visual disturbance(18%), Headache(17.7%) and Dyspnea(17.6%), etc. 6. Local syndrome and sign after snakebite is Discoloration(54.2%), Bleeding(20.2%), Bullae(10.7%), Skinulcer(10.8%), etc. 7. Pathological syndromes after snakebite are WBC increase, Urine protein, Urine sugar, Haematuria and elevation of S-GDT, S-GPT etc. These syndromes are leaded by Hematoxin and Cytolysin. 8. Complication signs after snakebite are Cellulitis, Gastritis, Lympoma, Abscess etc. 9. Common function of Viperidae(Agkistrodon acutus or Zaocys dhumnades etc) is expelling the wind(祛風), removing obstruction in the channels(通絡), antipastic function(止痙). And it is used in order to cure hemiparesis, hemiplegia, facial palsy and CVA disease, etc. 10. Using way of snake for medical treatment is various like Herbal alchol therapy, pill, powder and injection etc. The Study on the Snake Venom should be carried out continuously for using of medical treatment.

For the inactivation of venoms, the chemical methods are generally applied. In the chemical method many works have been carried out with the chemical reagents and immunological antiserums. However, all inhibitory effect of these chemicals acting on snake venomes may well be due not to the specific, but to the nonspecific inhibitory action. Therefore, it is necessary to separate venom into its compositional active proteins and develop specific inhibitor which acts on the each protein. Until now, there have not been any reports about the substance which acts on snake venom as a specific inhibitor. Recently in 1979, we had actually isolated a specific venom inhibitor(ISV) which has a strong inhibitory activity against the proteinase of snake venom of Colubridae. In our experiments described here, a strain of Aspergillus sp., isolated from soil, was able to produce a biological active substance. The partial crystallized substance had a strong inhibitory activity against hemorrhagic action of snake venom of Colubridae. For the inhibitory action of the sample on the lethality of venom, the substance prevented completely the lethal action of the hemorrhagic factor when they were treated with enough amount of the substance. The edema factor of whole venom of Agristrodon bromohoffi brevicaudus was completely inhibited, but those of HR-I and HR-II of Trimeresurus flavoviridis venom were inhibited about 50%, when they were treated with the substance of half amount of venom. On the other hand, from the result of subcutaneous hemorrhage in a rabbit, it was concluded that two kinds of antihemorrhagic substance might be produced by the strain used in this work.
