Value of hepatic iron measurements in early hemochromatosis and determination of the critical iron level associated with fibrosis

Mark L. Bassett, June W. Halliday, Lawrie W. Powell – 1 January 1986 – The role of the measurement of hepatic iron in the diagnosis of genetic hemochromatosis was studied, with particular reference to the differentiation of early hemochromatosis from alcoholic siderosis and the critical hepatic iron concentration associated with fibrosis in hemochromatosis. Hepatic iron was measured in 30 homozygous relatives of 17 hemochromatosis probands, 8 heterozygous relatives, 51 patients with alcoholic liver disease and 40 control subjects.

Intracellular processing of human vs. rat immunoglobulin A in the rat liver

Albert L. Jones, Gary T. Hradek, Douglas L. Schmucker – 1 November 1985 – It is well established that in the rat, rat dimeric IgA is transported from blood to bile across rat liver parenchymal cells via a series of minute smooth membrane‐limited vesicles. This pathway is unique from that taken by a number of other ligands, which are internalized for degradation, in that there appears to be little involvement of coated vesicles, multivesicular bodies and lysosomes.

A prospective clinical trial of D‐penicillamine in the treatment of primary biliary cirrhosis

Henry C. Bodenheimer, Fenton Schaffner, Irmin Sternlieb, Franklin M. Klion, Salvatore Vernace, John Pezzullo – 1 November 1985 – We conducted a prospective clinical trial to assess the relative efficacy and safety of high‐ vs. low‐dose D‐penicillamine in patients with primary biliary cirrhosis. Following clinical tests and liver biopsy diagnostic of primary biliary cirrhosis, 56 patients were randomized to receive either 250 or 750 mg D‐penicillamine daily. Patients were monitored with clinical tests and annual liver biopsy.

Transformation of bile acids into iso‐bile acids by clostridium perfringens: Possible transport of 3β‐hydrogen via the coenzyme

Ashok K. Batta, Gerald Salen, Sarah Shefer – 1 November 1985 – We have examined the mechanism for the bacterial transformation of chenodeoxycholic acid and lithocholic acid into the corresponding 3β‐hydroxy epimers with the use of 3α‐ and 3β‐tritiated bile acids. The 3‐oxo bile acids were transformed into the 3α‐ (85%) and 3β‐ (15%) hydroxy bile acids after 20‐hr incubation with Clostridium perfringens.

Chronic alcoholism enhances hepatocarcinogenicity of diethylnitrosamine in rats fed a marginally methyl‐deficient diet

Eduardo A. Porta, Nalani Markell, Russell D. Dorado – 1 November 1985 – To determine whether the chronic consumption of ethanol was capable of enhancing the hepatocarcinogenic activity of diethylnitrosamine per se, or through the accentuation of a methyl deficiency, two groups (A and B) of Sprague‐Dawley female rats were fed for 10 months either a 20% casein basal diet marginally deficient in methyl, or the same diet supplemented with choline (1 gm per 100 gm) and folic acid (0.54 mg per 100 gm).

Hepatitis B virus, hepatitis non‐A, non‐B virus and hepatitis delta virus in lyophilized antihemophilic factor: Relative sensitivity to heat

Robert H. Purcell, John L. Gerin, Hans Popper, William T. London, John Cicmanec, Jorg W. Eichberg, Jack Newman, Michael E. Hrinda – 1 November 1985 – Lyophilized plasma derivatives are more stable to heat than when they are in the liquid state. Commercial Factor VIII (antihemophilic factor) was seeded with a measured quantity of hepatitis B virus. The contaminated material was then lyophilized and subjected to heat of 60°c for 30 hr. Chimpanzees were inoculated with the heat‐treated antihemophilic factor or sham‐treated antihemophilic factor that had been held at 4°c.

Ultrastructural immunocytochemical demonstration of HLA class I antigens in human pathological liver tissue

Rita De Vos, Chris De Wolf‐Peeters, Joost J. Den Van Oord, Valeer Desmet – 1 November 1985 – Major histocompatibility complex products Class I (HLA Class I) antigens are not expressed on the surface of normal human hepatocytes but become so in pathological conditions. The purpose of this study was to specify the ultrastructural topography of HLA Class I antigens expression.

Screening methods for early detection of hepatocellular carcinoma

Kenichi Kobayashi, Tatsuho Sugimoto, Hiroshi Makino, Mikio Kumagai, Masashi Unoura, Nobuyoshi Tanaka, Yasuhiro Kato, Nobu Hattori – 1 November 1985 – The value of various screening methods in the detection of early hepatocellular carcinoma was investigated in 95 patients with cirrhosis. Infusion hepatic angiography and computed tomography with angiography were performed yearly, ultrasound every 3 months, and determination of serum α‐fetoprotein levels every 2 months. “Space‐occupying lesions” suspicious for hepatocellular carcinoma were found in 13 of the 95 cases (13.7%).
