*Creatinine and BUN (Blood Urea Nitrogen) were measured in blood plasma
Albumin, Lipocalin-2, Osteopontin, and KIM-1 (Kidney Injury Molecule-1) were measured in urine. Normal/Naive, plasma or urine drawn from naïve uninjured/untreated Wister rats served as base line. VPA (Valproic Acid), Dex (Dexamethasone) and Vehicle (saline control) treated groups at 3, 24 and 120 hour (h) reperfusion. Means with at least one common superscript (a, b or c) between 3, 24 or 120 h within each group (Vehicle, VPA or Dex) did not vary significantly (P>0.05).
