is a traditional Chinese herbal medicine with antioxidation, anti-inflammatory, antibacterial, and immunoregulation functions. A method to isolate polysaccharides from(LJP) has been reported previously by our group. We also reported previously that LJP was consisted of 6 types of monosaccharides and had the characteristic absorption of typical polysaccharides. In this study, we investigated the protective effect of LJP on cardiomyocytes of mice injured by hydrogen peroxide (HO). The results showed that LJP can increase the cardiomyocyte viability and the activities of the enzyme (SOD, CAT, GSH-Px, AST, CPK, and LDH) in cardiomyocytes of mice injured by hydrogen peroxide. The results of intracellular ROS contents showed that a high dose (40 g mL) of LJP had the best effects on protecting the cardiomyocytes of mice injured by HO. In addition, the measurement results of the cardiomyocyte apoptosis and the activity of caspase-3, caspase-8, and caspase-9 in cardiomyocytes confirmed this conclusion from another perspective.
