John D. Lutton, Margaret O. Griffin, Miki Nishimura, Richard D. Levere, Attallah Kappas, Nader G. Abraham, Shigeki Shibahara – 1 May 1993 – Exposure of Hep3B cells to metalloporphyrins (tinprotoporphyrin and heme) or cobalt chloride resulted in the production of a significant number of heme oxygenase transcripts, erythropoietin transcripts or both, as indicated by in situ hybridization.
Nicole Domingo, Huguette Lafont, Zamir Halpern, Yohanan Peled, Jean Grosclaude, Tuvia Gilat – 1 May 1993 – With the demonstration of pronucleating and antinucleating proteins, the role of biliary proteins became of considerable research interest. Anionic polypeptide fraction is the third most abundant biliary protein; it is found in association with biliary lipids, has antinucleating properties for calcium and is found in gallstones. Its levels in various human biles have not been studied as of this writing.
Albert Maroto, Pere Ginés, Vicente Arroyo, Angels Ginés, Joan Saló, Joan Clária, Wladimiro Jiménez, Concepció Bru, Francisca Rivera, Joan Rodés – 1 May 1993 – Brachial artery and common femoral artery blood flows and cardiac output were measured with duplex‐Doppler ultrasonography in 12 normal subjects, 12 patients with compensated cirrhosis and 35 patients with cirrhosis and ascites (8 with functional kidney failure). The aim of this study was to investigate whether arteriolar vasodilation in these vascular territories contributes to hyperdynamic circulation in cirrhosis.
Darrell H. G. Crawford, June W. Halliday, Kim M. Summers, Michael J. Bourke, Lawrie W. Powell – 1 May 1993 – Phenotypic concordance between siblings has been demonstrated in some inherited conditions, and such data provide strong evidence that the severity of disease is affected by genetic factors. We assessed the concordance of liver iron stores between siblings in 22 sibling pairs (15 same‐sex pairs and 7 opposite‐sex pairs) with genetic hemochromatosis.
Hideki Hagiwara, Norio Hayashi, Eiji Mita, Masafumi Naito, Akinori Kasahara, Hideyuki Fusamoto, Takenobu Kamada – 1 April 1993 – We describe a method for quantifying hepatitis C virus RNA in serum. This competitive assay combines reverse transcription and polymerase chain reaction and is based on coamplification of the target RNA with known amounts of synthetic mutated RNA.
Mar Decastro, Javier Sánchez, Jesús F. Herrera, Asunción Cháves, Rafael Durán, Luisa García ‐Buey, Carmelo García‐Monzón, Julia Sequí, Ricardo Moreno‐Otero – 1 April 1993 – The recent identification of the hepatitis C virus and development of assays to detect antibodies to hepatitis C virus has allowed assessment of the prevalence of hepatitis C virus infection in patients with a variety of liver and other diseases. The aim of this study was to investigate the prevalence of hepatitis C virus antibodies and severity of liver injury in patients with porphyria cutanea tarda.
S. K. Sarin, V. Bhatia – 1 April 1993 – Background. Endoscopic sclerotherapy is an accepted treatment for bleeding esophageal varices, but it is associated with substantial local and systemic complications. Endoscopic ligation, a new form of endoscopic treatment for bleeding varices, may be safer. We compared the effectiveness and safety of the two techniques.
James P. Corsetti, Janet D. Sparks, Barbara Sikora, Charles E. Sparks – 1 April 1993 – Hepatocellular heterogeneity of biochemical function is well established for many aspects of liver metabolism. This study addresses the question of cellular heterogeneity in the catabolism of low‐density lipoprotein by rat hepatocytes. Low‐density lipo‐protein binding (4° C) and uptake (37° C) by rat hepatocytes were studied by use of human low‐density lipoprotein labeled with a highly fluorescent lipophilic probe, N, N‐dipentadecylaminostyrylpyridinium iodide, recently developed by us.
Hani M. Rashed, Hui Sun, Tarun B. Patel – 1 April 1993 – To investigate whether atrial natriuretic factor regulates the growth of hepatocytes and to determine the receptor subtype involved in such modulation, we studied the effect of atrial natriuretic factor 103–126 and clearance receptor binding analogs of atrial natriuretic factor, (des‐(Q116, S117, G118, L119, G120) atrial natriuretic factor 102–121 and des‐(C105,121) atrial natriuretic factor 104–126) on growth of human hepatoblastoma cells.
Mei Mao‐Hua, An Wei, Zhang Bao‐Hong, Shao Qing, Gong De‐Zheng – 1 April 1993 – Hepatic stimulator substance was extracted from the liver of weanling Sprague‐Dawley rats according to the method of LaBrecque. Quang‐Ming mice were injected with carbon tetrachloride to induce acute liver failure. Hepatic stimulator substance suppressed the elevation of ALT and AST induced by carbon tetrachloride in a dose‐dependent manner.
