OBJECTIVE: To study the effects of xijiao dihuang decoction on the expressions of Bcl-2 and caspase-3 protein positive cells in brain tissue, TNF-alpha and IL-6 in blood after acute intracerebral hemorrhage in rat. METHOD: The experimental ICH model was established by injection of non-heparinized autologous arterial blood into the right basal ganglia. Immunohistochemistry and radioimmunity methods were used to detect expressions of Bcl-2 and caspase-3 protein positive cells in brain tissue, TNF-alpha and IL-6 in blood. RESULT: After ICH, caspase-3 protein positive cells in brain tissue, TNF-alpha and IL-6 in blood increased obviously in the model group, caspase-3 protein positive cells, TNF-alpha and IL-6 were significantly reduced by treatment with Xijiao Dihuang decoction, on the contrary, Bcl-2 protein positive cells in brain tissue increased markedly. CONCLUSION: Xijiao Dihuang decoction can pretect nerve cell by reducing the expression of caspase-3, TNF-alpha and IL-6, increasing the expression of Bcl-2 after ICH in hemorrhagic brain damage.
