用体外培养血管内皮细胞观察川芎嗪对其分泌NO的影响 ,结果显示 ,川芎嗪能促进内皮细胞分泌NO ,说明川芎嗪对心血管系统作用除促进PGI2 有关外 ,还与NO释放有关
The effect of tetramethylpyrazine on the secretion of nitric oxide was observed by culturing vascular endothelial cells in vitro. The results showed that ligustrazine could promote the secretion of NO by endothelial cells, indicating that the effects of tetramethylpyrazine on the cardiovascular system are related to the release of NO in addition to the promotion of PGI2.
