Juhani Saarinen, Ritva Saarelainen, Kai O. Lindros – 1 March 1993 – To study zonation of liver gene expression, we obtained periportal or perivenous rat liver cell lysates virtually devoid of nuclear material by site‐directed digitonin infusion in situ. Total RNA was isolated, messenger RNAs were reverse transcribed and complementary DNAs were assayed after polymerase chain reaction–mediated amplification.

Harry L. A. Janssen, Luuk Berk, Rudolf A. Heijtink, Fiebo J. W. Ten Kate, Solko W. Schalm – 1 March 1993 – Interferon‐α therapy leads to HBeAg seroconversion in only one third of patients with chronic hepatitis B. In an attempt to increase the seroconversion rate, we investigated the combination of interferon‐α and zidovudine in a subset of patients with presumably low response rates for interferon‐α monotherapy.

Eugenio Gaudio, Luigi Pannarale, Paolo Onori, Oliviero Riggio – 1 March 1993 – Hepatic microcirculation has been related to liver function in several studies. The principle of this relationship lies in the sequential distribution of blood from the feeding vessels of the hepatic acinus to the central vein. This study was undertaken to investigate the progressive changes at different sites of the liver microvascular bed in the developing cirrhosis, both by light microscopy and scanning electron microscopy of corrosion casts.

Bernhard H. Lauterburg, Dana Liang, Felix A. Schwarzenbach, Kerry J. Breen – 1 March 1993 – Mitochondria of patients with alcoholic liver disease are morphologically abnormal, and mitochondria isolated from animals exposed to ethanol exhibit functional deficiencies in vitro. Because the functional consequences of the morphological alterations and the relevance of in vitro observations to mitochondrial function in alcoholic subjects are not clear, we assessed mitochondrial function noninvasively with a breath test.

Ronald L. Koretz, Maria Brezina, Alan J. Polito, Stella Quan, Judith Wilber, Robert Dinello, Gary Gitnick – 1 March 1993 – Using assays to detect antibodies against antigens (C‐100, 5‐1‐1, C‐22 and C‐33) of the hepatitis C virus, we tested stored sera from 40 patients prospectively identified as having non‐A, non‐B posttransfusion hepatitis. The 28 patients who demonstrated seroconversion (“documented hepatitis C”) had more severe initial disease; all 20 cases of chronic hepatitis occurred in this subgroup.

Dirk De Craemer, Marina Pauwels, Frank Roels – 1 March 1993 – Hepatocellular peroxisomes in 32 patients with cirrhosis were studied by means of catalase cytochemical and morphometric analysis. Seven normal human livers were used as controls. The severity of the cirrhosis was determined with the Child‐Turcotte criteria. Under the light microscope, a decrease in catalase staining was observed in 12 livers. Staining showed a weak inverse correlation with severity of the cirrhotic process. Peroxisomes revealed a perinuclear configuration in 24 patients.

Ching‐Lung Lai, Johnson Y. N. Lau, Pui‐Chee Wu, Henry Ngan, Hau‐Tim Chung, Stuart J. Mitchell, Timothy J. Corbett, Anthony W. C. Chow, Hsiang‐Ju Lin – 1 March 1993 – To evaluate the clinical efficacy of interferon‐α in hepatocellular carcinoma, 71 adult Chinese patients with histologically proven inoperable hepatocellular carcinoma were randomized to receive recombinant interferon‐α2a (50 × 106 IU/m2) intramuscularly three times a week (n = 35) or no antitumor therapy (n = 36).
