Yoshinobu Sato, Kazuhiro Tsukada, Yoh Matsumot, Toru Ab – 1 August 1993 – The effects of interferon‐γ and interleukin‐2 on liver regeneration after 70% hepatectomy in rats was studied immunohistologically, with special attention paid to major histocompatibility complex class II antigen expression. Liver regeneration 2 days after partial hepatectomy as assessed on the basis of bromodeoxyuridine labeling index revealed that regeneration was inhibited significantly in rats given a single dose of interleukin‐2 or interferon‐γ compared with rats that underwent only partial hepatectomy.

Jorge A. Bezerra, David P. Witte, Bruce J. Arono, Sandra J. Friezner – 1 August 1993 – We have cloned and characterized the gene and complementary DNA for a new kringle‐containing protein. Although the function of this protein is not known, it has been called hepatocyte growth factor–like protein because it shares the same structural domains as hepatocyte growth factor, with four kringle structures followed by a region homologous to serine proteases.

M. Sawkat Anwer – 1 August 1993 – Calcium ionophores such as ionomycin and A23187 are often used to determine the role of intracellular Ca+ + in cellular processes. Ionomycin but not Ca+ +‐mobilizing agonists increases basal intracellular pH in hepatocytes. To explain this difference in effects of agents that increase intracellular Ca+ + concentration, the mechanism of ionomycin‐induced increases in basal intracellular pH in isolated rat hepatocytes was studied.

Alexander S. Petrides, Dirk Schulze‐Berge, Christoph Vogt, Dwight E. Matthews, Georg Strohmeye – 1 August 1993 – Insulin resistance is a characteristic feature of glucose‐intolerant and diabetic cirrhotic patients. The pathogenic factors, however, that are responsible for the development of impaired glucose tolerance in cirrhosis, remain unclear.

Anna Castro, Wladimiro Jiménez, Joan Clária, Josefa Ros, Josep Maria Martínez, Marta Bosch, Vicente Arroyo, Jaume Piulats, Francisca River, Joan Rodés – 1 August 1993 – Impaired vascular responsiveness to angiotensin II is a common feature in human cirrhosis with ascites. The aim of this study was to investigate whether vascular reactivity to angiotensin II is also decreased in rats with carbon tetrachloride–induced cirrhosis and ascites and to assess the role of endogenous nitric oxide in this abnormality.

Frederick J. Carmichael, Hector Orrego, Victor Saldivia, Yedy Israel – 1 August 1993 – It has been postulated that the beneficial effects of the antithyroid drug propylthiouracil in the treatment of alcoholic liver disease depend primarily on the action of propylthiouracil in suppressing the increase in hepatic oxygen consumption induced by ethanol. The evidence for this effect of propylthiouracil is derived from studies in which liver oxygen consumption has been determined in in vitro preparations.

Antonio Benedetti, Luca Marucci, Cristina Bassotti, Raniero Mancini, Susanna Contucci, Anne Marie Jezequel, Francesco Orland – 1 August 1993 – Morphometric ultrastructural analysis of horseradish peroxidase–containing structures has been performed in vivo, in rat liver and, in vitro, in isolated bile ducts to determine whether a transcytotic vesicle pathway exists in biliary epithelial cells. In vivo, horseradish peroxidase (100 mg/kg body wt) was given by intraportal injection in normal rats (n = 15) or 1 hr after administration of 600 mg/kg valproic acid (n = 15).
