Aerobic Exercise-Assisted Cardiac Regeneration by Inhibiting Tryptase Release in Mast Cells after Myocardial Infarction

Figure 3

(a) Shows histological slides of cardiomyocytes of (i) sham+inertia, (ii) sham+exercise, (iii) infarction+inertia, and (iv) infarction+exercise groups stained with hematoxylin and eosin method. Black arrow demonstrated cardiomyocyte disarray. (b) Shows correlations between cardiomyocyte diameter and total MC density. (c) Shows a correlation between cardiomyocyte diameter and MC degranulation. The solid line is the line of finest fit on linear regression, and the dotted lines represent the 95% confidence. Linear regression analysis indicated an opposed correlation between the cardiomyocyte diameter and total MC density and degranulation from exercise training-induced cardiac hypertrophy.
