This study investigated the protective effect and mechanism of ginsenoside Rg1 in cardiomyocytes hypoxia/reoxygenation (H/R) model. Pretreatment with ginsenoside Rg1 (60-120 microM) reduced lactate dehydrogenase release and increased cell viability in a dose-dependent manner. Fluorescence analysis demonstrated ginsenoside Rg1 reduced intracellular ROS and suppressed the intracellular [Ca(2+)] level. Cell lysate detected an increase of T-SOD, CAT, and GSH levels. The myocardial protection of ginsenoside Rg1 during H/R is partially due to its antioxidative effect and intracellular calcium homeostasis. J. Cell. Biochem.
