摘要: 目的: 比较甘西鼠尾草和丹参两种注射液对大鼠急性脑缺血的影响, 并对其作用机理进行探讨。方法: 采用大脑中动脉阻断术(MCAO) 制作大鼠急性脑缺血模型, 采用计算机图像分析仪测定脑梗死的体积, TBA 比色法测定血清MDA 含量, 放免法测定血清SOD 含量;电子自旋共振(ESR) 法测定药物对羟自由基的清除作用。结果: 甘西鼠尾草注射液和丹参注射液均可明显减小急性脑缺血大鼠脑梗死体积, 降低血清MDA 含量, 升高血清SOD 含量, 体外清除羟自由基的作用甘西鼠尾草强于丹参。结论: 甘西鼠尾草和丹参两种注射液作用基本相同, 提示甘西鼠尾草有可能成为丹参的代用品。

Abstract: AIM: To compare the effect of s.miltiorrhize bunge injection (SMBI) and s.przewalsii maxim injection (SPMI) on acute focal cerebral ischemia in rats, and to study the mechanism of the actions of two agents. METHODS: Acute focal cerebral ischemia model was made by middle cerebral artery occlusion (MCAO) in rats, and cerebral infarction volume was determined quantitatively by computer microscopical image analysis instruments. MDA content in serum was determined by TBA colorimetric analysis.SOD content in serum was studied by radioimmunity method.The scavenging effect of hydroxyl radical (·OH) was measured by electron spin resonance technique (ESR). RESULTS: SMBI and SPMI could markedly reduce infarction volume after occlusion of middle cerebral artery and MDA content in serum in rats.SMBI could elevate SOD content in serum.Two injections could markedly inhibit the formation of hydroxyl radical (·OH), and the effect of SPMI was better than that of SMBI. CONCLUSION: The effects of both SMBI and SPMI are similar, and it is possible that SPMI as a satisfactory substitute for SMBI.
