Change in Caspase 3 positive cells in the rat hippocampus A: in the normal rat, caspase-3 positive cells (arrowheads) form a thin line in dentate gyrus (DG) region. B, C: DAPI stain and Merged image of control group; D, G: noise 15 and noise 30 days exposed rats exhibited highly expressed number of Caspase-3 positive cells; E, F, H, I: DAPI stain and Merged image of noise 15 and noise 30 days exposed group respectively; J: graph bar representation of total number of Caspase-3 positive cells. One-way ANOVA with Bonferroni post hoc test was used for the analysis of positive Caspase-3 positive cells count. The values are represented as Mean ​± ​SEM (n ​= ​6 animals/group) ∗∗p ​< ​0.01, ∗p ​< ​0.05. Pearson’s correlation test followed by linear regression was performed for correlation analysis.
