M. Junnila et al., BETAINE REDUCES HEPATIC LIPIDOSIS INDUCED BY CARBON-TETRACHLORIDE IN SPRAGUE-DAWLEY RATS, Veterinary and human toxicology, 40(5), 1998, pp. 263-266
Carbon tetrachloride-injected rats were given liquid diets with and wi
thout betaine for 7 d. Hepatic lipidosis was induced by 4 daily inject
ions of carbon tetrachloride (CCl4). Animals were killed and their liv
ers and blood taken for analysis of betaine. S-adenosylmethionine (SAM
), betaine homocysteine methyltransferase (BHMT), triglyceride, alanin
e aminotransferase and aspartate aminotransferase. Liver samples were
also processed and stained for histological examination. Supplemental
betaine reduced triglyceride in the liver and centrilobular hepatic li
pidosis induced by the CCl4 injections. In both the control and experi
mental groups receiving betaine, liver betaine, BHMT and SAM were sign
ificantly higher than in their respective groups not receiving betaine
. This study provides evidence that betaine protects the liver against
CCl4-induced lipidosis and may be a useful therapeutic and prophylact
ic agent in ameliorating the harmful effects of CCl4.
