【Abstract】 Purpose: To study the effect of Naomai Erhao Injection—a compound TCM injection for cerebrovascula diseases on protection of brain nerves from acute cerebral ischemic injury and its mechanism. Methods:The structure and functions of the rats’ brain were stu died by means of the electronic microscope, radionucliole tracer method and some other me thods. Results: Naomai Erhao Injection reduced the tissue injury of cerebral coxtex of rats with acute cerebral ischemia; increased the SOD, GSH-PX activity of ischemic brain ti ssue, reduced the LPO content and raised the 3H-dexoyglucose content in brain tissue. Conclusions: Naomai Erhao Injection can protect the brain nerves by lessening cerebrocellular injury caused by ischemia and its mechanism of action can protect the brain nerves by lesse ning the offensive from oxygen free radicals and lowering the energy consumption.更多还原
