Abstract: AIM: To study the protective effect of medicinal serum of Jiangtang compound recipe on endothelial cells which were damaged by H2O2. METHODS: The effects of medicinal serum of Jiangtang compound recipe on cell viability, concentration of malondialdehyde (MDA) , NO, endothelin-1 (ET-1) and activity of superoxide dismutase (SOD) were determined for human umbilical vein endothelial cells (ECV304) damaged by H2O2. RESULTS: The medicinal serum of Jiangtang compound recipe significantly improved the structural change of ECV304 cells damaged by H2O2 , suppressed the production of MDA and the content of ET-1, increased activity of SOD and the rate of animate cells, and promoted secretion of NO. CONCLUSION: The medicinal serum of Jiangtang compound recipe can resist the injury of ECV304 caused by H2O2 , playing a role in the protective effect.
