The data are expressed as mean ± SEM. (n = number of animals in each group = 5). The comparisons were made by one way ANOVA followed by Dunnent’s test.
ns = non-significant, STZ = Streptozotocin.
*p < 0.05 is considered as significant when compared to the control group (0 h).
***p < 0.001 is considered as extremely significant when compared to the control group (0 h).
