胡芦巴总皂苷对脑缺血保护作用

Protective effects of trigonella foenum graecum L.on acute cerebral ischemia

目的 研究胡芦巴总皂苷的抗脑缺血作用 ,并探讨可能的作用机制。方法 采用结扎小鼠双侧颈总动脉造成急性不完全性脑缺血模型 ,观察平均存活时间 ;另取小鼠断颅后测定断颅喘息时间 ;采用玻片法 ,观察胡芦巴总皂苷对凝血时间的影响 ;采用比浊法 ;观察其对体外血小板聚集率的影响 ,并测定全血粘度。结果 胡芦巴总皂苷 40、80、16 0mg·kg-1,延长小鼠平均存活时间 (P <0 0 5 ,P <0 0 1) ,及凝血时间 (P <0 0 1) ,抑制血小板聚集率 (P <0 0 1) ,80 ,16 0mg·kg-1延长断颅小鼠喘息时间 (P <0 0 1)且具剂量依赖性 ;80 ,16 0mg·kg-1在低 ,中切变率能降低兔血粘度 (P <0 0 5 )。

S AIM To study the protective effects of trigonella foenum graecum(TFGs) on acute cerebral ischemia. METHODS Acute incomplete ischemia was induced by ligaturing bilateral carotid arterise and cutting heads in mice, the survival time and asthmatic time were observed; the coagulation time was measured by sheet glass method,and the blood viscosity was also assayed; the platelet aggregation induced by collagen were studied by turbdimetry in vitro . RESULTS TFGs prolonged survival time, coagulation time and asthmatic time significantly and inhibited platelet aggregation ratio in rabbit,and decreased the blood viscosity. CONCLUSION TFGs has the protective effects on acute cerebral ischemia.
