Spontaneous Ca2+ release from a caffeine and ryanodine–sensitive intracellular Ca2+ store in freshly prepared hepatocytes
Shinji Osada, Yukio Okano, Shigetoyo Saji, Yoshinori Nozawa – 1 February 1994 – A considerable fraction of freshly prepared hepatocytes loaded with the fluorescent [Ca2+]i indicator fura‐2 exhibited spontaneous rhythmic fluctuations that tended to decrease with increasing length of incubation after isolation. These oscillations were dependent on the external Ca2+. They could no longer be observed when a Ca2+ chelator–(ethylenebis [oxyethylenenitrilo]) tetraacetic acid–was added to medium.
Pathways of intracellular trafficking and release of ferritin by the liver in vivo: The effect of chloroquine and cytochalasin D
Grant A. Ramm, Lawrie W. Powell, June W. Halliday – 1 February 1994 – We have previously shown that the clearance of exogenous ferritin and the release of endogenous ferritin into both serum and bile are altered by the microtubular inhibitor colchicine. In this study we further examined the role of the lysosome‐endosome pathway in ferritin metabolism.
Quantitative assessment of serum IgM anti‐HBc in the natural course and during interferon treatment of chronic hepatitis B virus infection
George Marinos, Heather M. Smith, Nikolai V. Naoumov, Roger Williams – 1 February 1994 – Serum IgM anti‐HBc was determined in 135 chronic HBsAg carriers with various categories of histological activity on liver biopsy and hepatitis B serological profile. Thirty‐three patients were treated with interferon‐α to investigate the correlation between serum IgM anti‐HBc with histological activity and viral replication, to evaluate the usefulness of pretreatment IgM anti‐HBc as a predictor of a successful response to interferon‐α and to examine the IgM anti‐HBc response during this treatment.

Predicting cholangiocarcinoma in patients with primary sclerosing cholangitis: An analysis of the serological marker CA 19‐9
Steven A. Rogers, Daniel K. Podolsky – 1 February 1994 – Primary sclerosing cholangitis (PSC) predisposes to the development of cholangiocarcinoma, a usually fatal complication that is difficult to diagnose. Serum concentrations of CA 19‐9, a tumor‐associated antigen, are frequently increased in patients with only cholangiocarcinoma. The aim of this study was to assess the value of an increased serum CA 19‐9 level for the diagnosis of cholangiocarcinoma in patients with preexisting PSC.
Endotoxin‐induced cytokine gene expression and excretion in the liver
Michael I. Luster, Dori R. Germolec, Takahiko Yoshida, Fujio Kayama, Morrow Thompson – 1 February 1994 – Peptide mediators, including tumor necrosis factor‐α, interleukin 1 and interleukin‐6, are associated with many chronic inflammatory diseases and septic shock. As such, considerable information has been collected by means of study of cytokine secretion from isolated cells or plasma cytokines during septic shock or inflammatory disorders.
Modulation of the asialoglycoprotein receptor in human hepatoma cells: Effect of glucose
Peretz Weiss, Gilbert Ashwell, Anatol G. Morell, Richard J. Stockert – 1 February 1994 – The hepatic receptor for asialoglycoproteins was found to be modulated by the glucose concentration in the medium of the human hepatoma cell line HepG2. The surface binding of asialoorosomucoid, a well‐documented ligand for this receptor, increased from 20 ng/mg of cellular protein to about 40 ng/mg as the glucose concentration was increased from 10 to 50 mg/dl.
Protective effect of the lazaroid U74006F in cold ischemia‐reperfusion injury of the liver
Carlos A. Cosenza, Donald V. Cramer, Scott A. Cunneen, Phillip J. Tuso, Hong K. Wang, Leonard Makowka – 1 February 1994 – Lipid peroxidation may play a major role in the loss of liver graft viability after prolonged cold ischemia and reperfusion injury.
