The Effect of Tetramethylpyrazine on Hydrogen Peroxide‐Induced Oxidative Damage in Human Umbilical Vein Endothelial Cells

: Tetramethylpyrazine has been widely used in traditional Chinese medicine to treat cardiovascular diseases such as atherosclerosis and hypertension. The underlying mechanism of cardioprotective effects, however, remains to be elucidated. Here, using human umbilical vein endothelial cells (HUVECs), we have assessed the protective effect of tetramethylpyrazine on H 2 O 2 ‐induced oxidative damage. After pre‐incubation with tetramethylpyrazine...
