Ursodeoxycholic acid–induced changes of plasma and urinary bile acids in patients with primary biliary cirrhosis

Adolf Stiehl, Gerda Rudolph, Richard Raedsch, Bernd Moller, Ulrich Hopf, Erich Lotterer, Johannes Bircher, Ulrich Fölsch, Jürgen Klaus, Richard Endele, Martin Senn – 1 September 1990 – Ursodeoxycholic acid treatment of patients with primary biliary cirrhosis may lead to relief of pruritus and improvement of biochemical liver tests. The changes in serum and urinary bile acids induced by ursodeoxycholic acid treatment were studied.

Pretranslational and posttranslational regulation of the EGF receptor during the prereplicative phase of liver regeneration

Staffan Johansson, Niclas Andersson, Göran Andersson – 1 September 1990 – We studied the regulation of the epidermal growth factor receptor mRNA and the number of epidermal growth factor binding sites in subcellular compartments involved in the biosynthesis and endocytosis of the epidermal growth factor receptor during the prereplicative phase of liver regeneration. The epidermal growth factor receptor mRNA, quantified by solution hybridization, decreased after partial hepatectomy, with a nadir of about 35% 18 hr after hepatectomy.

Predictive value of whole blood chemiluminescence in patients with alcoholic hepatitis

Françoise Lunel, Beatrice Descamps‐Latscha, Diane Descamps, Yves Le Charpentier, Patrick Grippon, Dominique Valla, Jean‐François Cadranel, Johannes Trum, Pierre Opolon – 1 August 1990 – Recent reports suggest that ethanol metabolism leads to reactive oxygen intermediates that may be responsible for the lesions observed in alcoholic hepatitis. This study investigated the production of reactive oxygen intermediates in peripheral blood phagocytes of patients with alcoholic hepatitis and attempts to evaluate its predictive value.

Liver tumor promoters stimulate growth of transplanted hepatocellular carcinomas

Per O. Seglen, Gunnar Sæter, Per E. Schwarze – 1 August 1990 – Cell suspensions or tissue fragments from primary hepatocellular carcinomas and benign neoplastic nodules, induced by treating rats with chemical carcinogens, were transplanted by intraportal injection or subcapsular implantation in the livers of syngeneic host rats. Both nodule and carcinoma transplants produced high numbers of hepatocellular carcinomas in the hosts 2 to 5 mo after transplantation.

The streaming liver: Can the age of a hepatocyte be determined from its position on the portohepatic radius?

Wouter H. Lamers – 1 August 1990 – Hepatocyte age was estimated from its distance from the portal tract. We have previously shown that hepatocytes are formed adjacent to the portal tract and stream toward the terminal hepatic vein, advancing at a daily velocity of 2 μm. Thus, the farther a cell from the portal tract, the older it is. This relationship between cell age and distance served here for the study of age‐dependent changes in the hepatocyte, particularly nuclear area and DNA content.
