Retinol palmitate pretreatment reduced myocardial I/R injury. A. Representative images of the infract area (INF: white), area at risk (AAR: red and white), and normal area (blue). B. Quantitative analysis of myocardial infarct ratio (INF/AAR). C. Quantitative analysis of serum CK-MB activity. I/R: ischemia/reperfusion. I/R+L: IR+retinol palmitate (12 mg/kg). I/R+H: I/R+retinol palmitate (36 mg/kg). Data are expressed as mean ± SD (n = 6 per group). *P < 0.05, versus Sham group. #P < 0.05, versus I/R group. $P < 0.05, versus I/R+L group.
