Effect of I-R on myocardial infarct size, effect of ischemic preconditioning (IPC) on myocardial infarct size in normal and diabetic rat heart, effect of DDZ pre-treatment, sodium nitrite perfusion on myocardial infarct size in diabetic rat heart and effect of 5-HD alone or in combination with DDZ and sodium nitrite on myocardial infarct size in diabetic rat heart. I/R, IPC, DM, DDZ, 5-HD denotes ischemia reperfusion, ischemic preconditioning, diabetes mellitus, daidzein and 5-hydroxy decanoate respectively. Values are expressed as mean ± S.D, a = p < 0.05 vs. sham control; b = p < 0.05 vs. I/R Control; c = p < 0.05 vs .IPC in diabetic rat heart; d = p < 0.05 vs. IPC in normal rat heart; e = P < 0.05 vs. IPC in DDZ pretreated diabetic rat heart; f = p < 0.05 vs. IPC in sodium nitrite perfused diabetic rat heart; g = p < 0.05 vs. IPC in DDZ pretreated, sodium nitrite perfused diabetic rat heart.
