Sultana S, Ahmad S, Khan N, Jahangir T: Effect of Emblica officinalis (Gaertn) on CCl4 induced hepatic toxicity and DNA synthesis in Wistar rats. Indian J Exp Biol. 2005 May;43(5):430-6.
A single dose of CCl4 (1 ml/kg body weight, po in corn oil) increased the levels of SGOT (serum glutamate oxaloacetate transaminase), SGPT (serum glutamate pyruvate transaminase), LDH (lactate dehydrogenase), glutathione-S-transferase and depletion in reduced glutathione, glutathione peroxidase and glutathione reductase. It also caused enhancement in the levels of lipid peroxidation (LPO) and DNA synthesis. There was also pathological deterioration of hepatic tissue as evident from multivacuolated hepatocytes containing fat globules around central vein. The pretreatment of E. officinalis for 7 consecutive days showed a profound pathological protection to liver cell as depicted by univacuolated hepatocytes. Pretreatment with E. officinalis at doses of 100 and 200 mg/kg body weight, prior to CCl4 intoxication showed significant reduction in the levels of SGOT, SGPT, LDH, glutathione-S-transferase, LPO and DNA synthesis. There was also increase in reduced glutathione, glutathione peroxidase and glutathione reductase. The results suggest that E. officinalis inhibits hepatic toxicity in Wistar rats. |
