Metabolic state of the rat liver with ethanol: Comparison of in vivo31phosphorus nuclear magnetic resonance spectroscopy with freeze clamp assessment

John H. Helzberg, Mark S. Brown, Daniel J. Smith, John C. Gore, Ellen R. Gordon – 1 January 1987 – In vivo31phosphorus nuclear magnetic resonance spectroscopy was used to measure the hepatic metabolic state in various groups of rats given ethanol, a control liquid diet or a solid chow diet. The use of selective presaturation pulses applied to the broad phosphorus resonances of immobile phospholipids permitted reliable determination of ATP/ADP ratios by quantitation of the ATP‐β and ATP‐γ peak areas.

Alcoholic liver injury: Defenestration in noncirrhotic livers—a scanning electron microscopic study

Thomas Horn, Per Christoffersen, Jens H. Henriksen – 1 January 1987 – The fenestration of hepatic sinusoidal endothelial cells in 15 needle biopsies obtained from chronic alcoholics without cirrhosis was studied by scanning electron microscopy. As compared to nonalcoholics, a significant reduction in the number of fenestrae and porosity of the sinusoidal lining wall (fractional area of fenestrae) was observed in acinar Zone 3, both in biopsies with and without Zone 3 fibrosis as judged by light microscopy.

Fetal and adult human liver differ markedly in the fluidity and lipid composition of their microsomal membranes

Jaime Kapitulnik, Evelyn Weil, Ron Rabinowitz, Michael M. Krausz – 1 January 1987 – The fluidity and lipid composition of the human hepatic microsomal membrane were studied in 11 livers from 16‐ to 21‐week‐old fetuses and in 5 adult livers, and compared with those of fetal and adult rat liver microsomes. Membrane fluidity was analyzed by measurement of fluorescence polarization using the fluorophore 1,6‐diphenyl‐1,3,5‐hexatriene.

Low bone turnover state in primary biliary cirrhosis

Anthony J. Stellon, Adrian Webb, Juliet Compston, Roger Williams – 1 January 1987 – To determine whether bone loss in patients with chronic cholestatic liver disease is the consequence of a high or low bone turnover state, 30 female patients with biopsy‐proven primary biliary cirrhosis underwent iliac crest biopsy following double tetracycline labeling. The mean trabecular bone volume was decreased as a result of trabecular plate thinning in both the premenopausal (p < 0.02) and postmenopausal (p < 0.05) patients, compared to age‐ and sex‐matched controls.

Hemodynamic effects of a clonidine‐induced decrease in sympathetic tone in patients with cirrhosis

Richard Moreau, Samuel S. Lee, Antoine Hadengue, Alain Braillon, Didier Lebrec – 1 January 1987 – A decrease in plasma noradrenaline—a reflection of sympathetic nervous system activity—by clonidine, a centrally acting α2‐agonist, could reduce the hyperdynamic circulation observed in cirrhosis and may thereby decrease portal hypertension. Plasma noradrenaline concentration and plasma renin activity as well as systemic and splanchnic hemodynamics were measured in 12 patients with cirrhosis and ascites before and after administration of either 150 μg of clonidine or placebo.

Characteristics of serum IgA and liver IgA deposits in alcoholic liver disease

Albert Van De Wiel, Dominique L. Delacroix, Jan Van Hattum, Henk‐Jan Schuurman, Louis Kater – 1 January 1987 – Patients with alcoholic liver disease frequently reveal an increase in IgA serum concentration and IgA deposits in a continuous pattern along hepatic sinusoids. We investigated whether the hepatic IgA deposits are a passive reflection of changes in concentration or composition of IgA in the circulation, or represent a distinct effect of alcohol on the liver.

Ethanol‐induced increase in portal hepatic blood flow: Interference by anesthetic agents

Frederick J. Carmichael, Victor Saldivia, Yedy Israel, John P. McKaigney, Hector Orrego – 1 January 1987 – While a number of studies show that acute oral administration of ethanol results in increases in liver blood flow, a large body of evidence has also been presented in which such an effect is not observed. To shed light on this discrepancy, we have studied in rats, a number of variables that might modulate or inhibit the effect of ethanol.

Serum type III procollagen peptide concentrations in severe chronic active hepatitis: Relationship to cirrhosis and disease activity

Arthur J. McCullough, William N. Stassen, Russell H. Wiesner, Albert J. Czaja – 1 January 1987 – To analyze the correlations between the presence of cirrhosis and hepatocellular inflammation and the serum concentrations of the amino‐terminal peptide of procollagen type III in chronic liver disease, we measured procollagen type III concentrations in paired serum samples from 46 patients (17 had cirrhosis) with severe chronic active hepatitis during a therapeutic treatment trial.
