Schisandrin Protects against Norepinephrine-Induced Myocardial Hypertrophic Injury by Inhibiting the JAK2/STAT3 Signaling Pathway

Figure 2

Detection of the apoptosis rate by Hoechst fluorescence staining (scale bar: 25 μm). (a) Morphological changes of nuclei assessed by Hoechst fluorescence staining. (b) Statistical chart of the apoptosis rate of myocardial cells in each group. (c) Statistical graph of changes in the surface area of myocardial cells in each group. (d) Statistical graph of changes in the protein/DNA ratio of cardiomyocytes in each group. Ld, low dose; Md, medium dose; Hd, high dose; a,  < 0.05 vs. the control group; b,  < 0.05 vs. the model group; c,  < 0.05 vs. the captopril group; and d,  < 0.05 vs. the medium-dose schisandrin group.
