Figure 3: (a) Therapeutic effect of MC fruit extract on transverse section of left ventricular myocardial tissues of experimental rats examined by hematoxylin and eosin staining (×400, bar = 50 m). Cytoplasmic space (), n = nucleus. Quantitative analysis of transverse diameter of cardiomyocyte (bar graph). versus DM-MC group. (b) Therapeutic effect of MC fruit extract on transverse section of left ventricular myocardial tissues of experimental rats examined by Masson trichrome staining (×400, bar = 50 m). Collagen deposition (yellow arrows, blue staining). The bar graph showing fibrosis fractions in the myocardial tissue. versus DM-MC group. (c) Therapeutic effect of MC fruit extract on transverse section of left ventricular myocardial tissues of experimental rats examined by Azan trichrome staining (×400, bar = 50 m). Perivascular connective tissue depositions (stained dark blue, red arrows).
