摘要: 目的 研究蝮蛇毒血小板抑制因子(AHV-PI)对实验家兔动脉血栓形成的影响及其可能机制。方法 30只雄性家兔随机分为3组(n=10), 即对照组(假手术组),模型组,AHV-PI组(0.2 mg/kg)。以70%FeCl3溶液化学损伤的方法制备家兔颈动脉血栓模型。1 h 后经另一侧颈动脉采血,用双通道凝血仪测定家兔APTT、PT与TT以及血浆纤维蛋白原(FIB)含量,酶联免疫吸附法(ELISA)测定各血浆中纤溶酶水平。结果 与对照组相比较,模型组APTT、PT与TT均明显缩短(P<0.05),血浆中FIB含量增高(P<0.05),纤溶酶含量降低(P<0.05);与模型组

Abstract: AIM: To explore the effects and possible mechanism of platelet inhibitor from Agkistrodon halys venom (AHV-PI) on artery thrombosis in rabbit. METHODS: Thirty rabbits were divided into control group, artery thrombosis model group and AHV-PI (0.2 mg/kg) group (n=10) randomly. The model of rabbits carotid artery thrombosis was induced by infiltering 70%FeCl3.The blood was taken from another carotid artery after 1 hour.Automatic coagulation analyzer was used to determined the APTT,PT,TT and the content of fibrinogen(FIB).The plasma content of plasmin was determined by Enzyme-Linked Immunosorbnent Assay (ELISA). RESULTS: Compared with control group, significantly shortened APTT, PT, TT and reduced plasmin level were observed in artery thrombosis model group (P<0.05), while the level of FIB in plasma was increased (P<0.05). Obviously prolonged APTT and TT, reduced FIB (P>0.05) and plasmin level were discovered in AHV-PI group as compared with model group, while PT had no difference (P<0.05).CONCLUSION: AHV-PI can prevent the artery thrombosis.The mechanism may be related to plasminogen activation.

Key words: Agkistrodon halys venom, artery thrombosis, plasminogen activator
