Objective: To observe the effects of Shenmai(SM) injection on the neuronal apoptosis related gene expression in rat brain after intracerebral hemorrhage. Method: With Rosenberg models of rat intracerebral hemorrhage, we studied the pathologic changes of neuronal structure in hippocampal CA1 areas and gene expression of Bax and Bcl-2. Result: SM injection had effects on inhibiting the pyramidal cells apoptosis in the hippocampal CA1 areas, increasing the expression of Bcl-2 gene, and reducing the expression of Bax gene resulting deceased the ratio of Bax mRNA/Bcl-2 mRNA. Conclusion: SM injectio...
