Preventive Effects of NSAIDs on Lung Tissue Oxidative Damage in an Animal Sepsis Model

Abstract

Background/aim: Sepsis is a very heterogeneous syndrome that is caused by a dysregulated host response to infection. Inflammatory cascades have an important role in sepsis and can potentially be suppressed by anti-inflammatory compounds. So, this study was focused on the antiseptic effects of non-steroidal anti-inflammatory drugs (NSAIDs) on lung injuries based on cecal ligation and puncture (CLP) surgery. Materials and methods: Male wistar rats divided into 6 groups (n=50) as follows: Control, Laparotomy (LAP), CLP and three treatment groups. The rats were killed after 48 h and the lung tissue was subjected to antioxidant enzymes (LP (lipid peroxidation), MPO (myeloperoxidase), and GSH (Glutathione)) and inflammatory genes expression (cyclooxygenase-2 (COX-2), CD177 and MPO). Results: The results indicated that CLP caused lung injury by changes in antioxidant enzymes and genes expression (P
