(a) Renal histological features by H&E together with the immunofluorescence co-localisation of apoptotic bodies by TUNEL’s technique (green) with cleaved Casp-3 (red) and counterstaining with DAPI in the renal tissue specimens from all the study groups (40 × objective; scale bar = 10 µm). Moreover, (b) the relative expression of Casp-3 mRNA and protein alongside apoptosis index in the renal tissues from all groups are displayed as graph bars (data is shown as mean ± SD; a = P < 0.05 compared with the NC group; b = P < 0.05 compared with the PC group, c = P < 0.05 compared with the Pcal group and d = P < 0.05 compared with the OM group).
