title: Effect of tetrahydrocurcumin on erythromycin estolate-induced lipid peroxidation in rats.
abstract: Erythromycin estolate (EME), a potent macrolide antibiotic, generates free radicals, but their role in the development of liver toxicity is not yet well understood. The present study was carried out to investigate the effect of the antioxidant drug tetrahydrocurcumin (a metabolite of curcumin, the main component of turmeric) against EME-induced lipid peroxidation in rats. The oral administration of combined THC (80 mg/kg body weight) and EME (800 mg/kg body weight) for 15 days significantly decreased lipid peroxidation and enhanced cellular antioxidant defenses when compared with the group treated with EME alone. Supplemental histopathological examination of liver sections revealed that THC had a better antioxidant effect than Silymarin (200 mg/kg body weight), a reference drug. The results of this study indicate that THC affords significant protection against EME-induced lipid peroxidation.
