Refractory ascites: Modulation of atrial natriuretic factor unresponsiveness by mannitol

Gilles A. Morali, Sheldon W. Tobe, Karl L. Skorecki, Laurence M. Blendis – 1 July 1992 – We have previously shown that unresponsiveness to atrial natriuretic factor is a marker of the severity of ascites. The tubular mechanisms are unknown, but it seems that increased reabsorption of sodium proximal to the main site of action of atrial natriuretic factor (i.e., the inner medullary collecting duct) plays an important role. We attempted to decrease the proximal reabsorption of sodium with mannitol in patients unresponsive to atrial natriuretic factor.

Biglycan and decorin gene expression in normal and fibrotic rat liver: Cellular localization and regulatory factors

Dieter H. Meyer, Nora Krull, Kevin L. Dreher, Axel M. Gressner – 1 July 1992 – The expression of genes encoding the core proteins of the novel small chondroitin/dermatan sulfate proteoglycans decorin and biglycan was studied in the livers of normal rats and in liver tissue during fibrogenesis induced by prolonged bile‐duct ligation and thioacetamide poisoning. The cell types responsible for the expression of these transcripts and some key regulatory factors were identified. Both biglycan and decorin messenger RNAs were detected in normal liver tissue.

Interrelationships of bile acid and phospholipid fatty acid species with cholesterol saturation of duodenal bile in health and gallstone disease

Frieder Berr, Edgar Schreiber, Ulrich Frick – 1 July 1992 – The relative amount of cholesterol and the fatty acid composition of phosphatidylcholines in bile can be influenced by the bile acid species secreted.

Direct measurement of hepatic blood flow in native and transplanted organs, with accompanying systemic hemodynamics

A. William Paulsen, Goran B. G. Klintmalm – 1 July 1992 – The purpose of this study was to investigate intraoperatively a population of patients with end‐stage liver disease before and after liver transplantation with respect to (a) the range of hepatic and systemic hemodynamics and their changes associated with transplantation and (b) the ability to identify native hemodynamic correlates with specific diagnostic groups. Hepatic artery and portal vein blood flows were determined with square‐wave electromagnetic flowmetry.

Morphological differences between hepatocellular carcinoma and hepatocellular carcinomalike lesions

Ikuko Motohashi, Masahiko Okudaira, Tomoko Takai, Satoshi Kaneko, Noriaki Ikeda – 1 July 1992 – In an attempt to provide a quantitative basis for differentiation between well‐differentiated hepatocellular carcinoma and hepatocellular carcinomalike lesions (focal nodular hyperplasia, regenerative nodular hyperplasia and hepatocellular adenoma), histopathological and morphometrical analyses were performed on 208 cases of various liver diseases with the aid of an image analyzer.

Association between heterozygous β1‐antitrypsin deficiency and genetic hemochromatosis

Mordechai Rabinovitz, Judith S. Gavaler, Robert H. Kelly, David H. Van Thiel – 1 July 1992 – Primary hemochromatosis is a genetically determined autosomal recessive disorder characterized by the excessive accumulation of body iron, most of which is deposited in the parenchymal cells of various organs.

Urea and protein synthesis in cold‐preserved isolated rat hepatocytes

Paul K. Vreugdenhil, Diane C. Marsh, Folkert O. Belzer, James H. Southard – 1 July 1992 – We used an isolated‐hepatocyte model to study how hypothermic storage (simulating liver preservation) affects metabolism after prolonged preservation. Rat hepatocytes were stored in the University of Wisconsin solution for up to 72 hr. After each day of storage, protein synthesis, urea synthesis, ATP content and lactate dehydrogenase release were determined in rewarmed (37° C) and oxygenated hepatocytes.
