Differential distribution of hepatitis B core and E antigens in hepatocytes: Analysis by monoclonal antibodies

Mario Mondelli, Richard S. Tedder, Bridget Ferns, Patrizia Pontisso, Giuseppe Realdi, Alfredo Alberti – 1 March 1986 – Current knowledge on the expression of HBeAg in hepatocytes is incomplete because of difficulties in obtaining monospecific antisera devoid of anti‐HBc reactivity. In this study, we have examined by immunofluorescence the expression of HBcAg and HBeAgin cryostat liver sections from 25 chronic carriers of HBsAg using monoclonal antibodies.

Clinical, virologic and histologic outcome following seroconversion from HBeAg to anti‐HBe in chronic hepatitis type B

Giovanna Fattovich, Massimo Rugge, Lucio Brollo, Patrizia Pontisso, Franco Noventa, Maria Guido, Alfredo Alberti, Professor Giuseppe Realdi – 1 March 1986 – Seventy consecutive HBsAg‐ and HBeAg‐positive patients with biopsy‐proven chronic hepatitis were followed prospectively with serial determinations of SGPT levels and hepatitis B virus serum markers including HBsAg, HBeAg, anti‐HBeand hepatitis B virus DNA.

Epidemiology of hepatitis b e antigen and antibody in mentally retarded hbsag carriers

Ghanshyam Lohiya, Sunita Lohiya, Vinh Trong Ngo, Ramona Crinella – 1 March 1986 – Screening for HBeAg and anti‐HBe was performed on 133 carriers of HBsAg in aninstitution for the mentally retarded. By radioimmunoassay, the prevalences of HBeAg and anti‐HBe were determined to be 16 and 78%, respectively. HBeAg prevalence was significantly different in the following pairs of carriers: 70% in blacks, 10% in whites, and 35% incarriers with Down's syndrome, 8% in carriers without Down's syndrome.

Ultrastructure of experimental cocaine hepatotoxicity

Marcia R. Gottfried, Michelle W. Kloss, Doyle Graham, Elmer J. Rauckman, Gerald M. Rosen – 1 March 1986 – Cocaine is a potent hepatotoxin in mice. It is converted in the liver by a minor oxidative pathway to the active metabolite, norcocaine nitroxide. Previous studies have shown evidence of a lipid peroxidative mechanism of toxicity, including increased conjugated diene absorption by hepatic microsomal lipids following a single 60 mg per kg i.p. dose of cocaine in DBA/2Ha mice.

Value of ascitic lipids in the differentiation between cirrhotic and malignant ascites

Dieter Jüngst, Alexander L. Gerbes, Robert Martin, Gustav Paumgartner – 1 March 1986 – Ascitic fluid concentrations of cholesterol, triglycerides and phospholipids, were compared with ascitic fluid total protein in 40 patients with chronic liver disease, 51patients with various neoplasms and 1 patient with cardiac failure. Seven patients withboth chronic liver disease and malignancy were considered separately. The first 54 patients (23 cirrhotic and 31 with malignancy) were used to determine median values and ranges and to define the most suitable cutoff concentrations between both groups.
