Chronic administration of isoproterenol caused cardiac hypertrophy in SD rats. (A) Images of whole heart from control and isoproterenol-treated SD rat. (B) Heart weight and tail length ratio from control and isoproterenol-treated SD rat. (C) β-MHC gene expression from both control and hypertrophic heart measured by Real-time PCR. (D) ANP gene expression from both control and hypertrophic heart measured by Real-time PCR. Data shown as mean ± SEM, * p ≤0.05 versus control.
