Task: Intent Identification
Input (English): Not all alcoholic patients develop severe liver disease with fibrosis progressing to cirrhosis. It is of practical importance to determine whether some markers can predict progression of liver fibrosis.', 'We used a baboon model that mimics human alcoholic liver disease. Cytokeratin 7 and 19 expression and fat deposition were investigated in serial liver biopsies of 18 animals undergoing prolonged alcohol administration (range 2-17 years) and in four controls. Fibrosis was graded histologically and was also assessed quantitatively by image analysis.', 'Ten animals did not show a progression of liver disease even after 17 years of alcohol administration, but eight animals fed alcohol exhibited a progression of liver disease from no fibrosis or perivenular fibrosis to septal fibrosis or cirrhosis within 7 years. In normal liver, cytokeratin 7 and cytokeratin 19 immunostaining is restricted to bile duct cells. Hepatocellular cytokeratin 7 was observed only in those animals which progressed to more severe stages of fibrosis and it anticipated this progression by 4.2 years on average.
