Collagen content was measured in 38 needle liver biopsies (8 steatosis, 8 chronic hepatitis, 7 fibrosis and 15 cirrhosis) by a new colorimetric method based on the selective capacity of Sirius red and Fast green to bind to collagen and noncollagenous proteins, respectively. The values were compared with those obtained after determination of the degree of fibrosis by morphometry in the same tissue. In biopsies with cirrhosis and fibrosis, there was a higher amount of collagen than in biopsies with chronic hepatitis and steatosis. Furthermore, there was a highly significant direct correlation between the collagen content measured colorimetrically and the degree of fibrosis determined morphometrically (r = 0.77, p less than 0.001), suggesting that this new colorimetric method is useful in measuring the degree of fibrosis in needle liver biopsies.

SUMMARY The clinical data of 180 episodes of upper gastrointestinal bleeding in 168 patients with cirrhosis of the liver are examined. The source of bleeding had been determined by early endoscopy in all cases. In men under the age of 50 years, and without symptoms of liver failure, bleeding was due to ruptured gastro-oesophageal varices in 84 % of cases. Severe liver failure was associated with acute lesions of gastric mucosa in many cases. No presumptive diagnosis of the source of haemorrhage could be based on the examination of other clinical data (presence of ascites, mode of presentation and pattern of bleeding, history of ulcer disease, alcoholism, and previous medication).
