Russell H. Wiesner, Patricia M. Grambsch, E. Rolland Dickson, Jurgen Ludwig, Robert L. Maccarty, Ellen B. Hunter, Thomas R. Fleming, Lloyd D. Fisher, Sandra J. Beaver, Nicholas F. Larusso – 1 October 1989 – The natural history of primary sclerosing cholangitis was assessed in 174 patients; 37 were asymptomatic and 137 had symptoms related to underlying liver disease. At the time of diagnosis, the mean age was 39.9 years, 66% of the primary sclerosing cholangitis patients were male and 71% had associated inflammatory bowel disease, most commonly chronic ulcerative colitis.

Helmut Denk, Kurt Zatloukal, Karl‐Heinz Preisegger – 1 October 1989 – Polyclonal antibodies were raised which have a high affinity for conjugated ubiquitin. Immuno‐cytochemistry was performed on paraffin sections of tissues showing well‐characterized inclusion bodies. Ubiquitin was found as a component of the intermediate filament inclusion bodies characteristic of several major diseases including Lewy bodies of Parkinson's disease, Pick bodies of Pick's disease, Mallory bodies of alcoholic liver disease, cytoplasmic bodies of a specific myopathy, and Rosenthal fibres within astrocytes.

Dominique Valla, Jean‐François Flejou, Didier Lebrec, Jacques Bernuau, Bernard Rueff, Jean‐Louis Salzmann, Jean‐Pierre Benhamou – 1 October 1989 – We attempted to ascertain the mechanism of portal hypertension and ascites complicating acute hepatitis in 66 patients who underwent transvenous liver biopsy and measurement of hepatic venous pressure gradient.

Dieter Jüngst – 1 October 1989 – Gallbladder biles and stones were obtained at 116 cholecystectomies for symptomatic gallstone disease. All 33 patients younger than 50 years had cholesterol stones, whereas 40% of the older patients had pigment stones. We compared the reliability of three different bile tests for the differentiation between cholesterol and pigment stone patients.

Yves Ozier, Alain Braillon, Christophe Gaudin, Dominique Roulot, Antoine Hadengue, Didier Lebrec – 1 October 1989 – We investigated the effect of liver denervation on cardiovascular homeostasis. Three days after surgical denervation of the liver, hemodynamic studies (radioactive microsphere method) were conducted in conscious rats. The efficacity of the liver denervation procedure was confirmed by a significant decrease in norepinephrine content in various lobes of the liver. Liver denervation did not affect either systemic or splanchnic resting hemodynamics.

Sheila Sherlock – 1 September 1989 – Nailfold capillary microscopical and hormonal investigations were carried out in 25 patients with cirrhosis of the liver and in 20 age‐ and sex‐matched controls. Several structural and functional capillary microscopical parameters were significantly different between the group of cirrhotics as a whole and the controls; no capillaroscopic feature helped to distinguish cirrhotics with spiders from those without.

Herbert L. Bonkovsky – 1 September 1989 – Effects of iron were studied in cultured chick embryo liver cells to help elucidate the effect of hepatic iron in the human disease porphyria cutanea tarda and in toxic porphyria caused by chemicals.

Inmaculada Azorín, María‐Dolores Miñana, Vicente Felipo, Santiago Grisolía – 1 September 1989 – Rats were fed a standard diet or the standard diet supplemented with ammonium acetate (20% w/w) for up to 100 days. The effect of the ingestion of the high‐ammonium diet on some aspects of nitrogen metabolism in rats was studied. Ammonia levels in blood increased ≈3‐fold; in brain, liver and muscle the increases were 36, 34 and 50%, respectively. Urea levels in blood and urea excretion increased ≈2‐fold. There was no increase of carbamyl phosphate synthase.
