Histological analysis of the left ventricle in SHR.

<p>Sham and gonadectomized animals. A: number of myocyte nuclei/ high power field, B: cardiac fiber diameter. Representative images of histological analyses in C: sham male SHR, D: sham female groups, E: orchiectomized male groups and F: ovariectomized female groups. Samples were stained with hematoxylin/eosin (H&E): 400x. The results are the mean ± S.E.M. (n = 7 per group). Statistical significance is indicated by *P < 0.05 vs. females of the same group; ⁺P < 0.05 vs. sham animals of the same sex; (two-way ANOVA and Fischer test).
