Water Content of Gallstones: Location and Contribution to a Hypothesis Concerning Stone Structure

Roger D. Soloway, Eleanor B. Fayusal, Bruce W. Trotman, Norman E. Weston, James F. Ficca – 1 March 1982 – The water content of black pigment and cholesterol gallstones was evaluated with the use of moisture evolution analysis, electron spectroscopy for surface analysis, and X‐ray diffraction. X‐ray diffraction identified complex hydrated hydroxyapatite compounds in two stones. Moisture evolution analysis demonstrated that 18 pigment gallstones contained between 0.83 and 6.87% water; six cholesterol stones contained 0 to 0.27% (p < 0.001).

Inducer and Suppressor T‐Cells in Hepatitis B Virus‐induced Liver Disease

Howard C. Thomas, David Brown, Guitaine Routhier, George Janossy, Patrick C. Kung, Gideon Goldstein, Sheila Sherlock – 1 March 1982 – During acute type B hepatitis, the proportion of inducer to cytotoxic/suppressor T‐cells is decreased due to an increase in the concentration of suppressor cells. Similar changes are seen in chronically infected subjects with evidence of active viral replication (HBeAg positive) and chronic hepatitis of varying severity.

Ultrastructural and Biochemical Liver Analyses in Fabry's Disease

Stephan G. M. Meuwissen, Kurt P. Dingemans, Anneke Strijland, Joseph M. Tager, Bert C. M. Ooms – 1 March 1982 – Ultrastructural and biochemical analyses were made of liver biopsy material from a patient with longstanding Fabry's disease. Both hepatocytes as well as periportal macrophages showed lipid accumulations consisting of amorphous material as well as stacks of lamellar leaflets. Lipid inclusions in periportal macrophages were much larger than in hepatocytes. Furthermore, small round spheres were found exclusively in periportal macrophages.

A Mitochondrial Antigen‐Antibody System in Cholestatic Liver Disease Detected by Radioimmunoassay

Michael Manns, Karl‐Hermann Meyer, Zum Büschenfelde – 1 January 1982 – A radioimmunoassay (RIA) was established for the detection of antimitochondrial autoantibodies (AMAs) in patient sera. AMAs were detected by RIA in 12 of 14 patients with primary biliary cirrhosis and in 3 of 29 patients with chronic active hepatitis. AMAs were detected by indirect immunofluorescence in all sera positive by RIA.

Toxic Doses of Acetaminophen Suppress Hepatic Glutathione Synthesis in Rats

Bernhard H. Lauterburg, Jerry R. Mitchell – 1 January 1982 – The effect of a toxic dose of acetaminophen on hepatic glutathione turnover was studied in fed and fasted rats. Following the administration of 1 gm per kg of acetaminophen, the fractional rate of glutathione turnover increased from 0.19 to 0.28 hr−1 in fed rats and from 0.43 to 0.50 hr−1 in rats fasted for 48 hr. The increase in the fractional rate of turnover was proportionally much less than the decrease in hepatic glutathione concentration resulting from the toxic dose of acetaminophen.

A Comparison of Acute Reversible Pre‐ and Postsinusoidal Portal Hypertension on Salt and Water Retention in the Dog

Vernon Campbell, Paul D. Greig, Jeff Cranford, Bernard Langer, Melvin Silverman, Laurence M. Blendis – 1 January 1982 – To define the relationship between portal hypertension and renal excretion of salt and water, two acute animal models of portal hypertension were investigated. In both models, it was necessary for systemic and renal hemodynamics to remain unchanged during the creation of portal hypertension so as to eliminate the effects of change in these parameters on renal excretion.

Thyroxine Binding Globulin and Thyroid Function Tests in Patients with Hepatocellular Carcinoma

W. John Kalk, Michael C. Kew, Mervyn D. Danilewitz, Frederick Jacks, L. Andre Van Der Walt, Joseph Levin – 1 January 1982 – To determine the prevalence of elevated serum concentrations of thyroxine binding globulin (TBG) in patients with hepatocellular carcinoma (HCC) and the influence of the associated cirrhosis, TBG was measured in 39 patients with HCC, 22 with and 17 without cirrhosis, in 20 patients with cryptogenic macronodular cirrhosis but without HCC, and in 40 matched controls.
