Cardioprotective Potential of Aqueous Extract of Fumaria indica on Isoproterenol-Induced Myocardial Infarction in SD Rats

Figure 5

Effect of F. indica extract on representative photomicrograph of heart tissues dyed with 2,3,5-triphenyltetrazolium chloride. (a) The control group showed stained brick red region (dot), an indicator of viable tissue, (b) the isoproterenol- (ISO-) induced MI group showed marked unstained region (notched arrow), an indicator of total necrosis, (c) F. indica extract 10 mg/kg + ISO showed mild decrease in unstained region, (d) F. indica extract 30 mg/kg + ISO showed moderate decrease in unstained region, (e) F. indica extract 100 mg/kg + ISO showed marked decrease in unstained region, and (f) atenolol 10 mg/kg + ISO showed moderate decrease in unstained region. LV: left ventricle; RV: right ventricle.
