FIG. 4. Effects of cilostazol on the level of brain natriuretic peptide (BNP) expression in heart ventricles. The left panel shows representative immunoblots at 5 weeks after induction of myocardial infarct of the anterolateral left ventricular wall (A), and the right panel shows densitometric data (B). IOD: integrated optical density, GAPDH: Glyceraldehyde-3-Phosphate Dehydrogenase. Values are mean±SD. ^*p<0.05 vs. control group. Expression of BNP was significantly reduced by cilostazol treatment.
