Methods: The pathological diagnosis of glioma and tumor classification was by HE staining, and we use immunohistochemistry method to analyse the level of nNOS in different pathological grade glioma and the expression level of Cyt-c in mitochondria meanwhile. Results: The levels of nNOS were highest in grade III tumors, moderate in grade II tumors, and lowest different in grade I tumors. There was significant difference of the nNOS levels among different pathological grade tumors (P < 0.05). Furthermore, the similar phenomenon was observed in the expression level of Cyt-c in mitochondria (P < 0.05). Conclusion: The expression level of nNOS and Cyt-c in mitochondria was significantly related to the pathological grade of glioma.展开更多
