Role of selenium in protection of liver cirrhosis.


PMID 24191312

Abstract

Selenium is an essential trace element and has been shown to protect the rats against dietary liver necrosis. This study was designed to evaluate the effects of selenium supplementation on different biochemical parameters in thioacetamide induced cirrhotic rats. For this purpose 24 male Albino wistar rats were divided into four groups (n=6). Group I, remained healthy control rats, Group II, received thioacetamide (at a dose of 200mg/kg b.w, i.p, for 12 weeks, twice a week) in first phase and saline in second phase, Group III, received thioacetamide (200mg/kg b.w, i.p for 12 weeks, twice a week) in first phase and sodium selenite ((1mg/kg b.w, i.p. for 12 weeks, three times a week ) in second phase and Group IV, received sodium selenite (1mg/kg b.w, i.p. for 12 weeks, three times a week) in first phase and saline in second phase. Biochemical analysis was evaluated by total and direct bilirubin, liver specific enzymes, and antioxidant enzymes. Marked increase in total and direct bilirubin and ALT activity was the indicative markers of liver cirrhosis while reduced antioxidant activity (SOD and GSH) and increased MDA and Catalase levels were observed in cirrhotic group. Sodium selenite supplementation markedly reduced total bilirubin and ALT activity and restored the antioxidant enzymes (SOD and GSH) and MDA and catalase activity. These results indicate that sodium selenite successively attenuates the thioacetamide induced liver cirrhosis.
