23‐Methyl‐3α, 7β‐dihydroxy‐5β‐cholan‐24‐oic acid: Dose‐response study of biliary secretion in rat

Aldo Roda, Rita Aldini, Brunella Grigolo, Patrizia Simoni, Enrico Roda, Roberto Pellicciari, Pier Luigi Lenzi, Benedetto Natalini – 1 November 1988 – A side chain derivative of ursodeoxycholic acid, 23‐methylursodeoxycholic acid, was synthesized and the effect of i.v. infusion of the acid at different doses (0.75, 1.5, 3.0 and 6.0 μmoles per min per kg body weight over 1 hr) on bile flow, on its hepatic biotransformations and on biliary lipid secretion has been studied in bile fistula rats.

Distal splenorenal vs. portal‐systemic shunts after hemorrhage from varices: A randomized controlled trial

Norman D. Grace, Harold O. Conn, Robert H. Resnick, Roberto J. Groszmann, Colin E. Atterbury, Stephen C. Wright, Richard J. Gusberg, Rudolph Vollman, Guadalupe Garcia‐Tsao, Rosemarie L. Fisher, Edward T. O'Hara, William V. McDermott, J. Peter Maselli, Warren Widrich, Daniel S. Matloff, Douglas Horst, Naomi Banks, Jeanne Alberts – 1 November 1988 – Between 1975 and 1983, 303 cirrhotic patients with endoscopically proven major variceal hemorrhage were admitted to the participating hospitals of the Boston‐New Haven Collaborative Liver Group.

Long‐term follow‐up of anti‐HBe‐positive chronic active hepatitis B

Giovanna Fattovich, Lucio Brollo, Alfredo Alberti, Patrizia Pontisso, Giuliano Giustina, Giuseppe Realdi – 1 November 1988 – Twenty‐eight patients with chronic active hepatitis without cirrhosis who were positive for hepatitis B surface antigen and antibody to hepatitis B e antigen were followed for 1 to 15 years (mean 6.6 years) and underwent follow‐up biopsy.

Evidence for expression in human liver of halothane‐induced neoantigens recognized by antibodies in sera from patients with halothane hepatitis

J. Gerald Kenna, James Neuberger, Roger Williams – 1 November 1988 – Previous investigations have shown that antibodies in sera from patients with halothane hepatitis recognize neoantigens, expressed in livers of halothane‐exposed rabbits and rats, which consist of a halothane metabolite bound covalently to specific microsomal proteins. These studies have suggested that the patients' antibodies may play a role in the pathogenesis of the hepatitis.

Severe cholestasis leads to vitamin D depletion without perturbing its C‐25 hydroxylation in the dog

Victor Plourde, Marielle Gascon‐Barré, Bernard Willems, P.‐Michel Huet – 1 November 1988 – The role of the liver as a contributory factor in the vitamin D deficiency of cholestatic liver disease has been studied in vivo in dogs with chronic bile duct ligation, whereas controls underwent diversion of the bile flow through the urinary bladder via a choledococystostomy anastomosis.

Uptake and modification of 125I‐lipopolysaccharide by isolated rat Kupffer cells

Eben S. Fox, Peter Thomas, Selwyn A. Broitman – 1 November 1988 – While it is generally believed that hepatic clearance of lipopolysaccharide involves Kupffer cells, the mechanism involved has not been fully elucidated. This study assesses this phenomenon in terms of in vitro uptake and post‐uptake modification experiments with an 125I‐labeled Salmonella minnesota lipopolysaccharide. 125I‐Lipopolysaccharide was added to Kupffer cells in suspension cultures under a variety of conditions. In vitro uptake of 125I‐Lipopolysaccharide was not saturable up to concentrations of 33.33 μg per ml.

Hepatic dopamine sulfotransferases in untreated rats and in rats subjected to endocrine or hypertension‐related treatments

Sanford S. Singer, Mark R. Palmert, Michael D. Redman, Diane M. Leahy, Theresa C. Feeser, Mark J. Lucarelli, Linda S. Volkwein, Margie Bruns – 1 November 1988 – Here we describe the dopamine sulfotransferase activity of rat liver cytosol. With cytosol, 3′‐phosphoadeno‐sine‐5′‐phosphosulfate and dopamine Km values were 17.2 ± 4.1 and 22.4 ± 3.5 μM. Females possessed 23 to 37% of dopamine sulfotransferase levels, per gm liver, in males. DEAE‐Sephadex A‐50 chromatography resolved dopamine sulfotransferase activity to dopamine sulfotransferase I and dopamine sulfotransferase II.

Three‐dimensional view of the vascular structure of the lower esophagus in clinical portal hypertension

Makoto Hashizume, Seigo Kitano, Keizo Sugimachi, Katsuo Sueishi – 1 November 1988 – The venous anatomy of the lower esophagus and upper stomach was studied in nine patients with portal hypertension and in five without, following infusion of a silicon rubber compound into vessels of the excised organs within whole tissues made transparent with methyl salicylate. Four venous channels were identified in normal tissues: intraepithelial, subepithelial superficial, deep submucosal and adventitial veins.
