Protective effect of resveratrol on norepinephrine-induced normal neonatal cardiomyocytes cell death. a: Protective effect of 30 μM resveratrol (Rsv) on norepinephrine (NE: 5 μM)-induced cell death on normal neonatal mouse cardiomyocytes: some round cells characteristic of dying cells were observed by phase contrast microscopy under treatment with NE, which was significantly prevented with resveratrol pre-treatment. Data presented are means ± SEM, n = 3. *P < 0.05 versus control; # P < 0.05 versus NE. b: In the presence of 30 μM of resveratrol (Rsv), no cytotoxic effects (presence of round cells) were observed by phase contrast microscopy on normal neonatal cardiomyocytes. Data are means of three independent experiments; each experiment was done in triplicate. Data presented are means ± SEM, n = 3
