Background: Cisplatin (CP) is a potent chemotherapeutic agent commonly used for the treatment of various malignancies. It has varied undesirable effects such as nephrotoxicity, intestinal toxicity which limit its wide and extensive clinical usage. 18β-Glycyrrhetinic acid (GA) is a pentacyclic triterpenoid derivative, obtained from the herb liquorice having pharmacological properties such as anti-inflammatory, hepatoprotective and antioxidant. The present study was designed to investigate in vivo efficacy of GA against CP induced small intestinal toxicity.
Methods: Rats were subjected to prophylactic oral treatment of GA (50 and 100mg/kg body weight) for 21days against intestinal toxicity induced by single intra peritoneal injection of CP (10mg/kg body weight) on day 18th and sacrificed on 21st day.
Results: The plausible mechanism of CP induced small intestinal toxicity is via deficit in anti-oxidant armory, induction of oxidative stress; TNF-α, NFkB, activation of apoptotic pathway proteins by up regulation of caspases. However prophylactic treatment of GA diminished oxidative stress markers, TNF-α, NFkB expression and enhanced anti-oxidant status, down regulated apoptosis, recovered histopatholgical alterations in small intestine.
Conclusion: Therefore, results of the present finding provide strong evidence that GA may be a useful modulator in alleviating CP induced intestinal toxicity.
