Protective Effects of Monosodium-L-Glutamate on the Fatty Liver induced by Carbon Tetrachloride in Rat

사염화탄소-유발지방간에 대한 L-글루탐산 일나트륨의 보호작용

To achieve better understanding of the effects of monosodium-L-glutamate(MSG) against $CCl_4$ fatty liver in Wister male rats, 5% MSG solution was given as drinking water and $CCl_4$ 0.1 ml/kg was injected subcutaneously twice a week for four weeks. It was showed that increased hepatic phospholipid and hepatic triacylglycerol levels by $CCl_4$ challenge were significantly decreased by additionnal MSG, respectively. However, MSG had no apparent effect on the elevated hepatic cholesterol level in the presence of $CCl_4$. Histologically, additional MSG markedly inhibited fatty degeneration, spotty necrosis, inflammation and periportal vascular proliferation manifested by $CCl_4$. respectively. These results indicated that effects of MSG against $CCl_4$ induced-fatty liver appeared to be involved with partial restoration of altered hepatic lipid composition.
