Regenerating nodules–are they premalignant lesions?

Jorge J Gumucio, Teresa L. Wright – 1 June 1991 – In the period 1985–1988, 62 focal liver lesions in 58 cirrhotic patients were studied by ultrasonography; 12 of these focal lesions were documented to be regenerating lesions by echo‐guided fine‐needle biopsy. During an average follow‐up period of 10.2 months (range 3–22 months), hepatocellular carcinoma was subsequently found in 10 of the cases of regenerating nodules, whereas the initial diagnosis of regenerating nodule was confirmed in the remaining two cases.

FK 506–A promise of good things to come?

James Neuberger – 1 June 1991 – The new immunosuppressive drug FK 506 was used from the outset with low doses of prednisone to treat 120 recipients of primary liver grafts and 20 more patients undergoing liver retransplantation. The patient survival rate after 2 to 8 months in the primary liver transplantation series is 93.3%, with original graft survival of 87.5%. Of the 20 patients in the hepatic retransplant series, 17 (85%) are living. Almost all of the surviving patients have good liver function.

Compartmental analysis of steady‐state taurocholate transport kinetics by isolated rat hepatocytes

Thierry Coche, Xavier Deroubaix, Eric Depiereux, Ernest Feytmans – 1 June 1991 – We used compartmental modeling to describe taurocholate transport by isolated rat liver cells in suspension. Cells are preincubated in the presence of unlabeled taurocholate. When a steady‐state for taurocholate is reached, radiolabeled taurocholate is added to the medium and its exchange kinetics between the medium and the cells are followed over time. Because the studies are performed under steady‐state conditions, the kinetics can be described by linear compartmental models.

Comparative ultrastructural study of rat livers preserved in euro‐collins or university of wisconsin solution

Serge Fratté, Jean‐Louis Gendrault, Anne‐Marie Steffan, André Kirn – 1 June 1991 – University of Wisconsin solution greatly lengthens the time liver storage is possible compared with all previous solutions used. To test whether this improvement is related to better preservation of the endothelial cell, which is thought to be the most vulnerable cell type in cold storage, we compared time‐related ultrastructural changes in rat livers stored in this solution or in Euro‐Collins solution. Rat livers were harvested after combined arterial and portal perfusion with the cold‐storage solution.

Intralobular distribution and quantitation of cytochrome P‐450 enzymes in human liver as a function of age

Damrong Ratanasavanh, Philippe Beaune, Fabrice Morel, Jean‐Pierre Flinois, F. Peter Guengerich, Andre Guillouzo – 1 June 1991 – We have used immunohistochemical, immunoblotting and messenger RNA blotting approaches to study the distribution and quantitation of three cytochrome P‐450 enzymes, namely P‐450 IA2, P‐450 IIC and P‐450 IIIA and, for comparison, epoxide hydrolase and NADPH‐cytochrome P‐450 reductase in human liver.

Prospective, randomized controlled trial of interferon‐α in children with chronic hepatitis B

Mercedes Ruiz‐Moreno, Maria José Rua, Josefina Molina, Gloria Moraleda, Alberto Moreno, Jaime García‐aguado, Vicente Carréño – 1 June 1991 – Thirty‐six children with chronic hepatitis B were entered into a randomized controlled trial of recombinant human interferon‐α All patients had hepatitis B virus DNA and increased levels of aminotransferases in serum for at least 1 yr. Twelve children received 10 MU of interferon‐α 2b/m2 body surface area three times a week (group I); 12 children received 5 MU/m2 under the same conditions (group II); and 12 children served as controls (group III).

Improvement of estradiol 17β‐D‐glucuronide cholestasis by intravenous administration of dimethylethanolamine in the rat

Domenico Alvaro, Mario Angelico, Alfredo Cantafora, Eugenio Gaudio, Claudia Gandin, Maria Teresa Santini, Roberta Masella, Livo Capocaccia – 1 June 1991 – The intravenous administration of dimethylethanolamine in the rat promotes a selective enrichment of liver membranes with polyunsaturated phosphatidylcholines. The effect of dimethylethanolamine pretreatment on cholestasis induced by estradiol 17β‐D‐glucuronide, a potent cholestatic agent, was assessed in this study. Dimethylethanolamine, dissolved in sodium‐taurocholate was infused intravenously (0.3 mg/kg/min) for 15 hr.
