Fig 1: The effect of ISO and GC pretreatment on the serum NO and the iNOS/NOS2 levels in the myocardial tissue extracts of the experimental groups. Results are expressed as mean ± SD for groups of three observations, statistically significant at *** p < 0.001, ** p < 0.01, * p < 0.05 as compared to IG1 and ### p < 0.001, ## p < 0.01, # p < 0.05 when compared to IG2 as calculated by one-way ANOVA followed by Dunnet’s multiple comparison tests.
