Fe‐nitrilotriacetic acid—binding proteins associated with rat liver plasma membrane

D Barisani, M Wessling‐Resnick – 1 October 1996 – The uptake of nontransferrin‐bound iron by hepatocytes is known to occur and may contribute to the deposition of iron and resulting injury during hemochromatosis. To examine the proteins that may function in the transport of nontransferrin‐bound iron, the properties of FeNTA‐ binding to rat liver basolateral plasma membranes were characterized. The binding of 55FeNTA to purified liver basolateral plasma membranes was measured using a simple centrifugation assay.

Effects of brain death and glucose infusion on hepatic glycogen and blood hormones in the pig

K Roelsgaard, H E Bøtker, H Stødkilde‐Jørgensen, F Andreasen, S L Jensen, S Keiding – 1 October 1996 – We wished to study the effects of intravenous glucose/ insulin infusion to brain‐dead pigs on the hepatic glycogen content. Four groups of 40‐ kg pigs were studied: brain‐dead and control pigs given isotonic saline or glucose/insulin (7.5 mg glucose/kg/min, 1.25 mU insulin/kg/ min) (n = 5 to 10 in each group). Brain death was induced by inflating a balloon placed in the epidural space.

Accumulation and persistence of hepatitis B virus core gene deletion mutants in renal transplant patients are associated with end‐stage liver disease

S Günther, S Baginski, H Kissel, P Reinke, D H Krüger, H Will, H Meisel – 1 October 1996 – In renal transplant recipients, chronic hepatitis B virus (HBV) infection often leads to cirrhosis and liver failure. In this study, we investigated whether or not in these patients viral variants would emerge despite immunosuppression, and whether they are associated with a specific course of liver disease. In a population of 552 renal transplant recipients hepatitis B 24 surface antigen (HBsAg)‐positive patients were available for a 2‐year follow‐up.

Clinical hepatology: Profile of an urban, hospital‐based practic

D Byron, G Y Minuk – 1 October 1996 – To dispel the common notion that the practice of hepatology in North America largely consists of the care of middle‐aged male patients with alcohol‐induced liver disease, and, in the process, provide undergraduate and postgraduate students with a clearer picture of what patient profiles might resemble in an urban, hospital‐based hepatology practice, 1,226 charts derived from referrals between July 1, 1987, and January 1, 1994, were retrospectively reviewed for the following information: year of referral, age and sex of the patient, practice of the refer

Pathomorphological study of Kupffer cells in hepatocellular carcinoma and hyperplastic nodular lesions in the liver

M Tanaka, O Nakashima, Y Wada, M Kage, M Kojiro – 1 October 1996 – A pathomorphological study was conducted to clarify the localization of Kupffer cells in hepatocellular carcinoma (HCC) tissues and such hyperplastic nodular lesions as adenomatous hyperplasia (AH) and focal nodular hyperplasia (FNH). Materials were surgical specimens of 50 HCCs, 7 AHs, and 13 FNHs. These tissues were immunohistochemically stained with an anti‐human macrophage antibody (anti‐CD68 antibody).

A randomized controlled trial of thymosin‐α1 versus interferon alfa treatment in patients with hepatitis B e antigen antibody—and hepatitis B virus DNA—positive chronic hepatitis B

P Andreone, C Cursaro, A Gramenzi, C Zavaglia, I Rezakovic, E Altomare, R Severini, J S Franzone, O Albano, G Ideo, M Bernardi, G Gasbarrini – 1 October 1996 – It has recently been shown that thymosin‐α1(T‐α1), a synthetic polypeptide of thymic origin, is able to promote disease remission and inhibition of hepatitis B virus (HBV) replication in patients affected by hepatitis B e antigen (HBeAg)‐positive chronic active hepatitis. We evaluated the efficacy and safety of T‐α1 treatment in patients with hepatitis B e antibody (anti‐HBe) and HBV‐DNA‐positive chronic hepatitis.

Impaired stress and interleukin‐1β‐induced hypothalamic expression of the neuronal activation marker FOS in cholestatic rats

M G Swain, M Maric – 1 October 1996 – Both interleukin (IL)‐1β and psychological stress activate the hypothalamic‐pituitary‐adrenal (HPA) axis by stimulating neuronal activity within the paraventricular nucleus of the hypothalamus via different pathways. Because it has been shown previously that cholestatic rats show defective cytokine‐and stress‐induced HPA axis activation, neuronal activation in the paraventricular nucleus of rats with cholestasis caused by bile duct resection and in noncholestatic sham‐resected (sham) controls was examined.

Progressive decrease in tissue glycogen content in rats with long‐term cholestasis

L Krahenbuhl, C Talos, J Reichen, S Krahenbuhl – 1 October 1996 – Liver and skeletal muscle glycogen metabolism were investigated in rats 1 and 4 weeks after bile duct ligation (BDL) and in pair‐fed, sham‐ operated control rats. Livers were subjected to morphometric analysis to express glycogen content and enzyme activities per mL hepatocytes. One week after BDL, the hepatic glycogen content was 28.8 ± 13.8 versus 38.6 ± 16.4 mg/mL hepatocyte in BDL and control rats, respectively. Total activity of glycogen synthase (50.2 ± 7.0 vs.

Hepatic sinusoidal fibrosis induced by cholesterol and stilbestrol in the rabbit: 2. Hemodynamic and drug disposition studies

R Mastai, S Laganiere, I R Wanless, L Giroux, B Rocheleau, P Huet – 1 October 1996 – We assessed hepatic functions and systemic and splanchnic hemodynamics in a new model of hepatic sinusoidal fibrosis. Fibrosis was induced by the simultaneous administration for 8 weeks of diethyl‐stilbestrol (DES) (10 mg twice weekly, subcutaneously) and cholesterol‐supplemented diet (1%) in rabbits.
