Histopathology sections of the left ventricles collected from different groups of rats.( A, B) Histopathology sections of the left ventricle of the heart of control group shows myocardial layer (double headed arrow) with bundles of cardiomyocytes (arrow) with reasonable loose vascular connective tissue (arrowheads) between cardiac muscle bundles (X40 (left side) and X400 (right side); Hematoxyllin and Eosin stain); (C, D) Histopathology sections of the left ventricle of the heart of group B shows hypertrophied thickened myocardial layer (double headed arrow) with enlargement and hypertrophy of bundles of cardiomyocytes (arrow) with remarkable loss of connective tissue between cardiac muscle bundles and decrease in vascularity (X40 (left side) and X400 (right side); Hematoxyllin and Eosin stain); (E, F) Histopathology sections of the left ventricle of the heart of group C shows relatively normal myocardial layer (double headed arrow) with bundles of cardiomyocytes (arrow) with loose vascular connective tissue between cardiac muscle bundles (X40 (left side) and X400 (right side); Hematoxyllin and Eosin stain); (G, H) Histopathology sections of the left ventricle of the heart of group D shows relatively normal myocardial layer (double headed arrow) with bundles of cardiomyocytes (arrow) with loose highly vascular connective tissue between cardiac muscle bundles (X40 (left side) and X400 (right side); Hematoxyllin and Eosin stain)
