Methods: Acute pancreatitis was induced in rats by intramuscular injection of L-asparaginase (1,000 I.U/Kg) given daily for five days. Enoxaparin was given subcutaneous (100 I.U/Kg) and diclofenac was given intraperitoneal (2 mg/Kg) daily for five days. Then, markers of pancreatic injury, lipids, immune cell infiltration and oxidative stress were analyzed with histopathological examination of the pancreatic tissue. Results: During acutepancreatitis, oxidative stress markerswere significantly changed as indicated by reduced tissue glutathione and increased malondialdehyde levels. This wasaccompaniedby a significant increase in immune cells infiltration as indicated by thehigh level of myeloperoxidase (MPO) andpro-inflammatory cytokine TNF-alpha.
