Figure 1: The effects of combination of drug, i.e. p-coumaric acid and naringenin on heart SOD, CAT, GSH, thiobarbituric acid reactive substance (TBARS), in normal and doxorubicin (DOX)-induced myocardial infarction in Swiss albino rats. DOX = Doxorubicin, PC = p-coumaric acid, Vit = Vitamin, NR = Naringenin. *P < 0.05 is less significant as compared to Group I; ** P < 0.01 is signifi cant as compared to Group I; +P < 0.05 is less signifi cant as compared to Group II; ++P < 0.01 signifi cant as compared to Group II. Comparison between experimental and control groups were performed by ANOVA followed by Dunnett's test for post hoc comparison, when appropriate.
