George H. Nancollas – 1 September 1984 – The formation of crystalline components in gallstones is governed by the physical‐chemical factors controlling the crystallizaton of minerals in aqueous systems. The elucidation of the mechanism of these reactions, especially at the low supersaturations of interest in vivo, is facilitated by the use of a constant composition method in which the reactions are studied at supersaturation levels automatically sustained, potentiometrically, during the experiments.

BjÖRn Lindman – 1 September 1984 – Multicomponent self‐diffusion studies provide a general picture of amphiphile self‐association. Both micelles and microemulsions based on bile salts show a lower degree of association coopera‐tivity, lower aggregate charge densities and more extensive hydration than corresponding ionic surfactant systems. Effectively bicontinuous isotropic solutions of the microemulsion type are more easily formed by bile salts than by surfactants.

Hannu Väänänen, Mikko Salaspuro, Kai Lindros – 1 September 1984 – Periportal (pp) and perivenous (pv) hepatocyte populations were separated using a two‐diree‐tional closed perfusion technique with selective addition of collagenase either to direct or retrograde perfusions (Vaananen, H. et al., Liver 1983; 3:131). The activity of GPT in hepatocytes from the pp‐area was 1.9 times higher than in cells from the pv‐area (p < 0.01).

Lawrence S. Friedman – 1 July 1984

Marshall M. Kaplan, John V. Gandolfo, Elaine G. Quaroni – 1 July 1984 – We have developed an enzyme linked immunosorbant assay (ELISA) for antimitochondrial antibody. Polyvinyl microtiter plate wells are coated with partially purified rat kidney mitochondria, and excess protein binding sites are blocked with bovine serum albumin. Human serum, diluted 1:1,000, is incubated for 1 hr. Then β‐galactosidase‐goat‐anti‐human IgG (H+L) is added followed by the substrate, p‐nitrophenyl‐β‐D‐galactopyranoside. The plates are then read at 404 nM in a microelisa autoreader.

Jacqueline S. Partin, Cynthia C. Daugherty, A. James Mcadams, John C. Partin, William K. Schubert – 1 July 1984 – All childhood liver biopsy specimens from The Cincinnati Children's Hospital Research Foundation which had been prepared for light and electron microscopy were reviewed to identify biopsies from children with salicylate intoxication. Only two cases of primary salicylate intoxication were identified.

Fayez K. Ghishan, Harry L. Greene, Susan Halter, John A. Barnard, J. Roberto Moran – 1 July 1984 – The majority of infants with cytomegalovirus hepatitis have resolution of the disease with little evidence of fibrosis; there are only rare instances of cirrhosis. We report an infant with cytomegalovirus hepatitis who developed portal hypertension and hematemesis at 3 months of age. Liver biopsy showed resolution of the hepatitis but the presence of noncirrhotic sinusoidal fibrosis.

Mary J. Ruwart, Bob D. Rush, Nanette M. Friedle, Jerzy Stachura, Andrzej Tarnawski – 1 July 1984 – Male rats were treated with subcutaneous vehicle or 16, 16‐dimethyl‐PGE2 (dmPGE2, 100 μg per kg), 24,18 and 0.5 hr prior to and 6, 24 and 30 hr after challenge with oral α1‐napthylisothio‐cyanate (ANIT, 30 mg per kg). Forty‐eight hours after challenge, rats were sacrificed by decapitation; serum and liver samples were taken for biochemical and histological analysis, respectively.
