Abstract
The present study was conducted to determine the effect of corynoline (COR) against sepsis-induced acute lung injury (ALI) in Wistar rats. Results of the study suggested that COR causes significant inhibition of lipid peroxidation (malondialdehyde) together with inhibition of oxidative stress (superoxide dismutase, catalase, glutathione peroxidase, and myeloperoxidase). The level of various proinflammatory (tumor necrosis factor-alpha, interleukin-8, and migration inhibitory factor) was also found to be reduced in COR-treated rats after sepsis. The protective effect of COR was further substantiated by the histopathology of lung tissue, where it improves the architecture of alveolar spaces. In western blot analysis, COR causes significant inhibition of nuclear factor kappa-light-chain-enhancer of activated B cells activation in the lung tissue homogenate. Our results demonstrated that COR was able to prevent the progression of ALI in rats via inhibition of inflammation and oxidative stress.
