Abstract
Despite medical advancements, the inflammatory cascade and oxidative stress worsen the prognosis in most cases of peritonitis. Curcumin has emerged as a potential antioxidant and anti-inflammatory agent in few of the acute inflammatory and infective conditions. We examined the effect of intraperitoneal injection of curcumin in endotoxin-induced peritonitis in rats. The blood and peritoneal fluid samples were collected at 3 and 24h following the induction of peritonitis. Animals were sacrificed at 24h and the organs preserved. The histopathological report of lung, liver, and intestines in the curcumin-treated rats showed maintenance of tissue architecture to a large extent compared to the control group which showed massive congestion, hemorrhage, and necrosis. The blood and peritoneal fluid total count and differential neutrophil counts were significantly higher at 24h of induction of peritonitis. Serum amyloid assay and lipid peroxidation were significantly lower, and myeloperoxidase assay was higher in the curcumin-treated group at the end of 24h; thus, curcumin probably demonstrated a neutrophil-mediated immunopotentiation and anti-inflammatory action thereby protecting the animal from endotoxemia-induced multi-organ damage.
