I Aguilar‐Delfin, F López‐Barrera, R Hernández‐Munoz – 1 September 1996 – It has been proposed that lipid peroxidation (LP) might be a modulator of cell division, influencing initiation and cessation of mitosis in regenerating liver. However, the understanding of the participating role of this event in the onset of liver proliferation has been hampered by the fact that both higher or lower LP have been reported after two‐thirds partial hepatectomy (PH).

O A Rayyes, A Wallmark, C Florén – 1 September 1996 – The aim of this study was to elucidate the possible causes of elevated low‐density lipoprotein (LDL)‐cholesterol levels in transplanted patients treated with the immunosuppressant drug, cyclosporine. HepG2 cells, from a well‐differentiated cell‐line of hepatoma cells, were cultured and used as a model for in vitro hepatocytic LDL uptake. Different concentrations of cyclosporine, which were within the range of concentrations found in humans treated with cyclosporine, were added to tissue culture medium together with 125I‐LDL.

F Braet, R De Zanger, D Jans, I Spector, E Wisse – 1 September 1996 – This report describes the effect of the actin‐disrupting marine toxin latrunculin A on the cytoskeleton and fenestrae of liver endothelial cells (LECs). Fluorescence microscopy and whole mount‐transmission electron microscopic preparations of isolated, purified, and cultured LECs showed that latrunculin A, which sequesters actin monomers and depolymerizes actin filaments, caused profound changes in microfilament organization in LECs.

R Huang, C Chen, Y Huang, D Hsieh, C Hu, C Chen, C Chang – 1 September 1996 – During screening of Chinese herbal medicines for the activities against hepatitis B virus (HBV), a known pure compound, osthole, was found to inhibit the secretion of HBV surface antigens in vitro. The secretion of hepatitis B surface antigen (HBsAg) in culture medium of MS‐G2 and HuH‐7 cells transfected with HBV DNA decreased by 60% to 70% after osthole treatment, without any detectable cytotoxic effects.

N Nakayama, H Kashiwazaki, N Kobayashi, J Hamada, Y Ogiso, Y Itakura, K Matsumoto, T Nakamura, T Koike, N Kuzumaki, N Takeichi – 1 September 1996 – The Long‐Evans Cinnamon (LEC) rat is characterized by the spontaneous onset of acute and chronic hepatitis, followed by occurrence of liver cancer, and is thus able to provide a unique experimental model for human genetical liver disease, Wilson's disease. Hepatocyte growth factor (HGF) is a potent hepatotrophic factor in liver regeneration, and its expression is up‐regulated in response to liver injuries.

C N Van Der Veere, B Schoemaker, C Bakker, R Van Der Meer, P L Jansen, R P Elferink – 1 September 1996 – The aim of this study was to test a possible form of therapy that could be used in the management of unconjugated hyperbilirubinemia. We hypothesized that unconjugated bilirubin (UCB) can permeate the intestinal wall and can thus be secreted with the feces. We have previously observed that UCB binds to amorphous calcium phosphate in vitro.

E Hatano, A Tanaka, S Iwata, S Satoh, T Kitai, S Tsunekawa, T Inomoto, H Shinohara, B Chance, Y Yamaoka – 1 September 1996 – The liver plays an important role in maintaining homeostasis during endotoxin‐triggered systemic inflammatory response. To study the effects of phosphocreatine on hepatic energy metabolism after endotoxin administration, we used transgenic mice whose livers express creatine kinase (CK). CK catalyzes a phosphocreatine/creatine reaction, that is, an adenosine triphosphate (ATP) reservoir system.

O Fonia, R Weizman, R Coleman, E Kaganovskaya, M Gavish – 1 September 1996 – There is evidence to suggest that peripheral‐type benzodiazepine receptors (PBR) are involved in porphyrin transport during erythroid differentiation, and it is possible that these receptors have an important role in heme biosynthesis. We examined the biochemical and ultrastructural alterations in rat liver following experimentally induced acute hepatic porphyria, as well as the effects of the administration of a selective PBR ligand, PK 11195.
