Figure 2: Paricalcitol reduces isoproterenol-induced myocardial hypertrophy in rats. (a) Using immunofluorescent staining analysis, heart sections were stained with wheat germ agglutinin. Isoproterenol induced myocardial hypertrophy, while paricalcitol improved myocardial hypertrophy induced by isoproterenol. (b) The area of myocardial hypertrophy was statistically analyzed. Statistical values are presented as mean ± standard error of the mean; n = 9. *P < 0.05 compared to the control group, #P < 0.05 compared to the isoproterenol group.
