Objective: To evaluate the effects of quercetin on the injured vascular endothelial cells and its mechanism. Method: Endothelial cell culture was in vitro. The endothelial cell injury model was established by cultured with H2O2 for 18 h
Quercetin at dose of 8
4
2 mg·L-1 was cultured with the cells before the model establishment. Flow cytometry was used for determining endothelial cell death rate. Endothelial cell was detected by ELISA for medium thrombomodulin(TM) content; spectrophotometric determination was used for the culture medium lactate dehydrogenase(LDH) activity. Result: Compared to the model group
quercetin can lower endothelial cell death rate
reduce the content of TM and activity of LDH in the culture medium. Conclusion: Quercetin can obviously protect endothelial cells
and its protective effect is related to against lipid peroxidation
