Figure 1: Histopathology changes in the myocardial infarction of control and experimental rats. Effect of fenugreek on the histopathology of the myocardium. (a) Normal rats (group I) showing normal cardiac cells. (b) Isoproterenol (85 mg/kg bodyweight)- induced rats (group II) showing perivascular cuffi ng of vasa vasorum with intimal fi brosis, disruption of medial elastic fi bers with diffuse interstitial fi brosis and myocytolysis. (c) Fenugreek (250 mg/kg bodyweight) treated rats (group III) showing normal architecture of cardiac cells. (d) Fenugreek (250 mg/kg body weight) + isoproterenol (85 mg/kg bodyweight)- induced rats showing normal architecture of cardiac cells
