Abstract

The recovering effect of betaine (derivative of choline) on carbon tetrachloride (CCl4)-injured liver was investigated by oral and intraperitoneal administration of betaine at 24h after acute CCl4 in-toxication. The effect of betaine was estimated by the activity of alanine aminotransferase (ALT) released into the serum, histological score, and the incorporation of S-phase indicator (5-bromo-2-deoxyuridine/5-fluoro-2-deoxyuridine; BrdU/FdU). A significant decrease in the activity of serum ALT was observed by the intraperitoneal (3mg/kg body) or oral (15mg/kg body) administration of betaine. Furthermore, an increase in the uptake of BrdU into the hepatocyte nuclear DNA and a reduction in liver necrosis after the oral treatment of betaine (15mg/kg body) was observed. From these results, the administration of betaine showed a significant effect in recovering CCl4-injured liver.
