Hideaki Suzuki, Shinsuke Iyomasa, Yuji Nimura, Shonen Yoshida – 1 November 1994 – We previously showed that hepatic cells proliferate in obstructive jaundice alone without partial hepatectomy and found that external biliary drainage for obstructive jaundice markedly suppresses liver regeneration after partial hepatectomy. In this study, we produced a model system for internal biliary drainage in which bile was drained into the stomach of rat fed a liquid diet.

Julio Martín, Juan A. Quiroga, Orencio Bosch, Vicente Carreño – 1 November 1994 – Recombinant human granulocyte‐macrophage colony‐stimulating factor therapy significantly reduces serum hepatitis B virus DNA levels, associated with increased 2′, 5′‐oligoadenylate synthetase activity in cultured mononuclear cells of patients with chronic hepatitis B.

Francjan J. Van Spronsen, Yolande Thomasse, G. Peter A. Smit, James V. Leonard, Peter T. Clayton, Vaclav Fidler, Ruud Berger, Hugo S. A. Heymans – 1 November 1994 – Hereditary tyrosinemia type I (McKusick 27670) is a heterogeneous disease with poor prognosis, yet there are few reports of the long‐term prognosis. It is therefore difficult to decide on the treatment for individual patients. We have conducted an international survey of patients with tyrosinemia type I and examined the probability of survival on dietary treatment and the causes of death in 108 patients with tyrosinemia type I.

Daniel Alvarez, Diego Golombek, Patricia Lopez, Marcelo De Las Heras, Luis Viola, Susana Sanchez, Miguel Kolker, Ricardo Mastai – 1 November 1994 – A close temporal relationship between higher levels of portal pressure during the night and the peak incidence of acute variceal bleeding has recently been demonstrated in patients with cirrhosis. Because hemodynamic changes may have a role in triggering this hemorrhagic episode, we measured systemic and portal hemodynamic parameters at 4‐hr intervals for 24 hr in 12 cirrhotic patients.

Ai‐Min Hui, Seiji Kawasaki, Masatoshi Makuuchi, Jun Nakayama, Toshihiko Ikegami, Shinichi Miyagawa – 1 November 1994 – The influence of normothermic ischemia on steatotic liver was compared with that on healthy liver in rats. Steatotic liver was induced with 4 wk of a cholinedeficient diet. We used a procedure of subcutaneous spleen transposition to develop portosystemic collaterals to avoid splanchnic stasis during total hepatic vascular occlusion.

Yoshiyuki Kanazawa, Norio Hayashi, Eiji Mita, Tiancheng Li, Hideki Hagiwara, Akinori Kasahara, Hideyuki Fusamoto, Takenobu Kamada – 1 November 1994 – The quasispecies nature of hepatitis C virus genome distribution is most evident in hypervariable regions of the putative envelope 2 domain. Eight patients with chronic hepatitis C treated with interferon‐α were studied as to heterogeneity of the hypervariable regions to clarify the implications of quasispecies.

Morio Yamada, Takashi Nishigami, Keiji Nakasho, Yukiyasu Nishimoto, Hideki Miyaji – 1 November 1994 – An increasing amount of evidence suggests that the sigma (σ) sites, putative targets for a variety of psychotomimetic and antipsychotic drugs, exist not only in the brain but also in various peripheral organs. However, there are many ambiguities as to their biological roles, subcellular distributions, endogenous ligands and so on. We therefore performed our study for clarification of some of these ambiguities.
