O. Sergent, B. Griffon, I. Morel, M. Chevanne, M. Dubos, P. Cillard, J. Cillard – 30 December 2003 – An iron‐mediated oxidative stress caused by an increase of the intracellular pool of low molecular weight complex of iron (LMWC) can be observed with iron overloading or ethanol metabolism. The aim of this study was to determine whether nitric oxide (NO) behaved as a pro‐oxidant or an antioxidant in such an iron‐mediated oxidative stress in rat hepatocytes.

G. I. Slapak, R. Saxena, B. Portmann, E. Gane, J. Devlin, R. Calne, R. Williams – 30 December 2003 – In this clinicopathological study, we have examined the prevalence of biochemical and histological graft abnormalities in 116 patients who have lived for longer than five years since orthotopic liver transplantation (mean, 8.4 years [range, 5.2‐19.5 years]). In each patient, the protocol biopsy was carried out in addition to full clinical, biochemical, and immunological evaluation.

S. Minamitani, S. Nishiguchi, T. Kuroki, S. Otani, T. Monna – 30 December 2003 – The clinical diagnosis of infection with the most common precore mutant of hepatitis B virus (HBV), that with a point mutation from guanine to adenine at nucleotide 83 in the precore region, is important because the disease may progress rapidly despite interferon therapy. A practical method to detect this mutant is needed. With the ligase chain reaction (LCR), target DNA sequences can be amplified and single base mutations can be detected.

B. M. Ho, S. K. So, C. O. Esquivel, E. B. Keeffe – 30 December 2003 – It has been suggested that Asian patients have reduced survival after liver transplantation because of greater recurrence of hepatitis B virus (HBV). We analyzed the outcome of Asian and non‐Asian patients receiving transplants for chronic hepatitis B between May 1988 and March 1994. Baseline Child‐Pugh score and United Network for Organ Sharing (UNOS) status, HBV recurrence, and survival were compared between the two groups. All but one patient received variable doses of hepatitis B immune globulin.

J Renau‐Piqueras, R Guasch, I Azorín, J Seguí, C Guerri – 30 December 2003 – Prenatal exposure to alcohol affects the morphological, structural, and functional features of the Golgi apparatus (GA), thus altering the glycosylation process in fetal hepatocytes. To elucidate the cellular mechanisms underlying these alterations, we have studied the effect of alcohol exposure in utero on the activity of liver galactosyltransferase, an enzyme involved in the glycosylation process, and on the hepatic glycoprotein sugar composition.

H Shibuya, N Ohkohchi, K Seya, S Satomi – 30 December 2003 – This study was designed to determine the source of reactive oxygen species (ROS) and whether Kupffer cells modulate the injury of perfused rat liver after cold preservation. The livers of male Lewis rats pretreated with schizophyllan glucan (SPG) (10 mg/kg, SPG group) or gadolinium chloride (5 mg/kg; Gd group) and untreated rats (control group) were preserved in University of Wisconsin solution for 0, 12, and 24 hours at 4 degrees C and then perfused for 60 minutes with oxygenated Krebs‐Henseleit bicarbonate buffer.

A Masini, D Gallesi, F Giovannini, T Trenti, D Ceccarelli – 30 December 2003 – Cocaine hepatotoxicity may be mediated by oxidative damage, possibly involving mitochondrial injury. The effect of an acute dose of cocaine in rats on the mitochondrial level of reduced glutathione, nicotinamide adenine dinucleotide (NADH) and nicotinamide adenine dinucleotide phosphate (NADPH), important determinants in cellular defense against oxidative stress, was investigated.
