In vivo protective effect of cinnamon aqueous extract in carbon tetrachloride-treated male albino rats

Resumo

The liver as an organ is important for the metabolism of drugs and toxins. However, it is not immune from environmental insults. Exposure of liver cells to carbon tetrachloride (CCl₄) results in the generation of tricholoromethyl radicals, which induce liver toxicity. This study aims at investigating the ameliorative effect of the cinnamon aqueous extract (CAE) against CCl₄-induced hepatotoxicity in male albino rats. Hepatotoxicity was induced in rats through the intraperitoneal administration of 0.5 mL kg^-1 body weight of CCl₄. The analyses of the results obtained showed significant reduction in the levels of serum biochemical markers for 400 and 600 mg kg^-1 bw of CAE protected rats as compared with CCl₄ group. In addition, CAE administration reversed liver tissue damaged via increased antioxidants markers. Histopathological examination of CAE treatment on rats showed improved changes to the liver damage caused by CCl₄ with no evidence of steatosis and inflammation. This result hence suggests that CAE has marked hepatoprotective and healing activities against CCl₄-induced liver damage and could serve as a suitable candidate in drug discovery for the treatment of liver toxicity.
