RESUMO
An experimental studies were carried out to observe the protective effects of malotilate, a new antihepatotoxic agent, on the chronic hepatic injury induced by CCl4 with or without ethanol. The rats used weighed about 200g were divided into 2 groups, 4 weeks & 8 weeks. Each group was given by orally with malotilate, 100 mg/kg, once a day, and was injected by subcutaneously with CCl4 1.5 mg/kg in a mixture with olive oil twice a week. Aqueous ethanol (20%) was administered in drinking water daily. The serochemical and histopathological studies were carried out in each experimental group. The results were as follows: 1. The chronic liver injuries induced by CCl4 with or without ethanol were significantly ameliorated by normalize serum values GOT, GPT. Alkaline phosphatase, Cholesterol, HDL-Cholesterol, and gamma glutamyl transpeptidase. 2. In Group of 4 weeks, malotilate manifested protective effects by significant inhibition of fatty changes, spotty necrosis and fibrosis in CCl4-intoxicated liver with or without additional ethanol. 3. In group of 8 weeks, malotilate significantly imoproved fatty changes, fibrogenic activity in the group administered with CCl4, followed by ethanol.

A study was made; of the effect of malotilate on the acute liver injury induced by carbon tetrachlorid,e ( CC14 ) and d-galactosamine in mice. Malotilate ( 50~150mg/kg ig?3 ) significantly inhibited the elevation of serum glu tamic pyruvic transaminase ( SGPT ) in CC14- intoxicated mice.At the dose of 100mg/kg ig?3, malotilate remarkably increased the content of hepatic glycogea in CCl4-injected mice. The contents of serum protein, liver protein, and cytochrom P-450 in liver hemogenate were increased by malotilate ( 100mg/kg ig?3) in CC14-intoxicated mice. The drug also reduced the accumulation of liver triglycerides induced by CCl4 in mice.In addition to, malotilate(50mg /kg, ip?5) could act against the increase of SGPT and the decrease of liver protein content induced with d-galactosamine in mice. These results suggest that malotilate may be a new therapeutic agent for liver injury.
