英文摘要 | Y.-S. Li, K.-F. Liu, Q.-C. Wang, Y.-L. Rpan and G.-C. Tu. A platelet function inhibitor purified from Vipera russelli siamensis (Smith) snake venom. Toxicon23, 895–903, 1985. — By means of CM-Sephadex C-50 column chromatography and gel filtration on Sephadex G — 75, a potent platelet function inhibitor was purified from Vipera russelli siamensis venom. It appeared as a single protein band on polyacrylamide gel electrophoresis in the presence or absence of SDS, and consists of 123 amino acid residues. Its NH3-terminal residue is serine. It showed the following characteristics: molecular weight, 13,800; isoelectric point, 10.4; ld(In50), 0.5 ± 0.12 mg/kg (i.v.). The platelet inhibitor exhibited phospholipase A2 activity with a specific activity of 35 μmoles/min/mg. From 2 g of the venom, 70 mg of the purified inhibitor was obtained. Inhibition of human platelet aggregation induced by ADP or adrenaline was dose-dependent, with id(In50) of 1.14μg/ml or 0.37 μg/ml, respectively. The platelet aggregation induced by thrombin or collagen was also inhibited and the inhibitory activity on platelet aggregation was heat stable (at 100°C, 20 min) in an acidic medium (pH 5.8), while its phospholipase A2 activity was relatively heat labile under the same condition. The release of 3H-serotonin in platelets stimulated by ADP was also inhibited and this was positively correlated with inhibition of platelet aegregation induced by ADP (r = 0.998, P < 0.002). |
