Protective effects of dihydrolycorine on hypoxia/reoxygenation injury in cultured neonatal rat cardiomyocytes / 中国药理学通报

ABSTRACT

Aim To investigate the protective effects of dihydrolycorine on hypoxia/reoxygenation (H/R) injury in cultured neonatal rat cardiomyocytes. Methods The hypoxia/ reoxygenation injury model of cultured neonatal rat cardiomyocytes was developed. The cell livability, the activity of lactate dehdrogenase (LDH) and superoxide dismutase (SOD), and the content of malondialdehyde (MDA) were determined in the cultured neonatal rat cardiomyocytes injured by H/R. Results Compared with normal group, the cell livability and the SOD activity of model group were decreased respectively, whereas the activity of LDH and the content of MDA of model group were increased significantly (P
