Fig. 2

Effect of regular exercise on the density (a) and percentage of degranulation (b) of cardiac mast cells (MCs) in ovariectomized (OVX) rats. Images are transverse sections of the ventricle at ×40 magnification from sham-operated controls (SHAM) and from OXV rats with no further treatment (OXV), with estrogen supplementation (OVX + E2), or with exercise training (OVX + Ex). Cardiac MCs were identifiable by their dark-purple coloration (arrowheads) due to toluidine staining. Box plot of number of cardiac MCs per tissue area (a) and percentage MC degranulation (b) from the Sham-operated (control) group (SHAM) and from the three treatment groups of OXV rats (+oil, +E2, +EX). Top and bottom of box Minimum and maximum values, horizontal line within the box median. Data are from 6–7 hearts in each group. Asterisk and hash symbols Significant difference (P < 0.05) from SHAM and OVX groups, respectively, using the Student–Newman–Keuls test after ANOVA
