Figure 6 Effect of oxidized low-density lipoprotein (ox-LDL), nitro-L-, and D-arginine methyl ester hydrochloride (L- and D-NAME), bradykinin, nebivolol, and atenolol on endothelial nitric oxide synthase (eNOS) activity in bovine aortic endothelial cells (BAECs). Ox-LDL (50 µg protein/ml), L- and D-NAME (2 mmol/l), bradykinin (100 nmol/l), nebivolol (25 µmol/l), and atenolol (25 µmol/l) were preincubated with BAECs for 5 min at 37°C. Results are expressed as pmol citrulline/mg protein/min and are means ± SD of experiments performed in triplicate in six separate occasions. *p < 0.001 versus control.
