Shamimunisa B. Mustafa, Chandrashekhar R. Gandhi, Stephen A. K. Harvey, Merle S. Olson – 1 February 1995 – Endothelins are potent peptide mediators that elicit glycogenolytic and vasoconstrictor actions in the liver. Endothelins were found to stimulate the synthesis and release of the lipid mediator platelet‐activating factor in cultured rat Kupffer cells. Endothelin‐mediated synthesis of platelet‐activating factor required extracellular calcium in that the calcium chelator, EGTA and nifedipine, a calcium ion channel blocker, inhibited platelet‐activating factor synthesis.

Campbell, John M. Ham, Henry D. Appelman, Jeremiah G. Turcotte – 1 February 1995 – A double‐blind placebo‐controlled trial of intravenous prostaglandin PGE1 (40 μg/h) was conducted in adult orthotopic liver transplant recipients. Infusion was started intraoperatively and continued for up to 21 days. Patients were followed up for 180 days postoperatively.

Mehmet Ozturk – 1 February 1995 – Fifty‐eight percent of hepatocellular carcinomas (HCCs) from Qidong, China, contain an AGG to AGT mutation at codon 249 of the p53 tumor suppressor gene, a mutation that is rarely seen in HCCs from Western countries. The population of Qidong is exposed to high levels of aflatoxin B1 (AFB1), a fungal toxin that has been shown to induce the same mutation in cultured human HCC cells.

Ricard Solà, Montserrat Andreu, Susana Coll, Maria Carme Vila, Maria Isabel Oliver, Vicente Arroyo – 1 February 1995 – Diuretic treatment in cirrhotic patients with ascites increases ascitic fluid concentration of total protein and complement components, and opsonic activity. These changes are not observed in patients treated with paracentesis. Based on these data it has been suggested that therapeutic paracentesis may be associated with an increased risk of spontaneous bacterial peritonitis (SBP) development.

Patrizia Paterlini, Karine Poussin, Michael Kew, Dominique Franco, Christian Brechot – 1 February 1995 – In HBsAg‐negitive patients with hepatocellular carcinoma (HCC), hepatitis B virus (HBV) genomes are present at a low copy number per cell, and the role of HBV in liver transformation is still unclear.

Keith D. Lindor, Christine H. Janes, Jeffrey S. Crippin, Roberta A. Jorgensen, E. Rolland Dickson – 1 February 1995 – Ursodeoxycholic acid (UDCA) has been proposed as beneficial therapy for patients with primary biliary cirrhosis (PBC). The effects of UDCA on metabolic bone disease, a major source of morbidity in patients with PBC, are essentially unknown. Preliminary information suggests that UDCA may improve biochemical indices of bone disease, although information about the effects of bone disease, although information about the effects of UDCA on bone density is lacking.

Betty L. Slagle – 1 February 1995 – We studied 80 hepatocellular carcinomas from three continents for p53 gene (TP53) mutations and hepatitis B virus (HBV) sequences. p53 mutations were frequent in tumors from Mozambique but not in tumors from South Africa, China, and Germany. Independent of geographic origin, most tumors were positive for HBV sequences. X gene coding sequences of HBV were detected in 78% of tumors, whereas viral sequences in the surface antigen‐ and core antigen‐encoding regions were present in less than 45% of tumors.

Eugenio Morsiani, Mary Mazzoni, Arrigo Aleotti, Paolo Gorini, Daniele Ricci – 1 February 1995 – Accumulation of lipids in the hepatocyte cytoplasm after partial hepatectomy (PH) has long been recognized, but the mechanism behind this phenomenon is still poorly understood. In this study, rats subjected to a standard two‐thirds PH showed early and marked increase in portal venous pressure (P < .01).
