Histopathologic scores (Mean± SD) of renal cortex and outer medulla at 3, 24 and 120 hours (h) post ischemia-reperfusion (IR) in Valproic Acid (VPA) and Dexamethasone (Dex) treated animals.

Mean values within columns among treatment groups with at least one common superscript letter (a or b) did not vary significantly (P>0.05). Also, mean values in rows between cortex and medulla (within 3h, 24h or 120h post-IR) groups with a common superscript number did not vary significantly (P>0.05). Vehicle (saline) served as a control. N = 8/sub-group (3, 24 or 120 h). Histopathologic scores (Mean± SD) of renal cortex and outer medulla at 3, 24 and 120 hours (h) post ischemia-reperfusion (IR) in Valproic Acid (VPA) and Dexamethasone (Dex) treated animals.
