摘要
目的 探讨血小板活化因子 (PAF)受体拮抗剂海风藤新木脂素类成分对鼠脑梗死面积、局部脑血流量 (rCBF)及神经功能缺失征象的影响 ,并与传统的PAF受体拮抗剂银杏苦内酯相比较。方法 利用TTC染色结合球积仪、氢清除法组织血流计和临床神经功能评分标准等方法 ,分别对缺血、缺血再灌注及海风藤新木脂素类成分、银杏苦内酯治疗组鼠脑梗死面积、rCBF、神经功能缺失征象进行观察和比较。结果 海风藤新木脂素类成分、银杏苦内酯药物治疗组脑梗死面积较缺血再灌组明显减小 ,同时药物能改善缺血侧皮质rCBF的下降 ,并显著减轻脑缺血后的神经功能缺损。
AIM To compare the effect of Piper Futokadsura Neoligans with Ginkgolides, a platelet activiting factor receptor antagonist, on cerebral ischemic area,region cerebral blood flow(rCBF) and neuroligic function deficits following focal cerebral ischemia/reperfusion in rats. METHODS The middle cerebral artery (MCA) focal cerebral ischemia and reperfusion rat models were used. The cerebral ischemic area, rCBF and neural function deficits were measured by TTC staining,hydyogen clearance and neurologic function scoring, respectively. RESULTS A significant reduction in infarct volume were found in the Piper Futokadsura Neoligans treated group as well as in the Ginkgolides treated group compared with the control group.Furthermore, Piper Futokadsura Neoligans induced significant amelioration of the rCBF decrease and neurologic dysfunction following focal cerebral ischemia and reperfusion in rats. CONCLUSION Both Piper Futokadsura Neoligans and Ginkgolides have remarkable brain protective effects.
