Cell‐mediated cytotoxicity of sensitized spleen cells against target liver cells—in vivo and in vitro study with a mouse model of experimental autoimmune hepatitis

Teruo Mori, Yoshio Mori, Hiromichi Yoshida, Shiro Ueda, Makoto Ogawa, Kenji Iesato, Yoko Wakashin, Masafumi Wakashin, Kunio Okuda – 1 September 1985 – Spleen cells obtained from C57BL/6 (B6) mice with an experimental autoimmune hepatitis were transferred to normal C57BL/6 recipient mice. Most prominent liver damages occurred in the recipient mice injected with sensitized nylon wool column‐adherent spleen cells from the donor mice.

Production of two distinct and independent hepatic immunoregulatory molecules by the perfused rat liver

Francis V. Chisari, Mary Nakamura, David R. Milich, Keith Han, Daniel Molden, Geert G. Leroux‐Roels – 1 September 1985 – By manipulating dietary sugar intake and perfusate glucose concentration, we have identified two independent hepatic immunoregulatory molecules produced by the perfused rat liver. The first is released by injured hepatocytes, appears in perfusates together with hepatocellular glutamic pyruvic transaminase, is quantitatively inhibited by exogenous L‐arginine and coelutes with arginase on high‐pressure liquid chromatography.

The effect of 3‐palmitoyl‐(+)‐catechin on kupffer cells in guinea pig liver

Marcello Piazza, Guglielmo Borgia, Jane Crowell, Salvatore Nappa, Alberto Lambiase, Daniel Perrissoud, Werner Schreil – 1 September 1985 – We report a morphometric study on the effect of 3‐palmitoyl‐(+)‐catechin on phagocytic activity of latex particles by Kupffer cells in guinea pig liver. We found an increase in the density of latex particles in Kupffer cells of animals treated with 3‐palmitoyl‐(+)‐catechin. The volume and density of Kupffer cells of treated animals increased (p < 0.01); there was no significant difference in surface density of the plasma membrane.

Pathogenesis of steatorrhea in primary biliary cirrhosis

Stephen J. Lanspa, Albert T. H. Chan, J. Sumner Bell, Vay Liang W. Go, E. Rolland Dickson, Eugene P. Dimagno – 1 September 1985 – To investigate the pathophysiology of steatorrhea in primary biliary cirrhosis, the severity of steatorrhea, small bowel histology and function, cholestasis, exocrine pancreatic secretion and liver histology were studied. Twenty‐four primary biliary cirrhotic patients had a quantitative stool fat collection, serum bilirubin and alkaline phosphatase and liver biopsies.

Hepatocellular carcinoma in young, mentally retarded HBsAg carriers without cirrhosis

Ghanshyam Lohiya, Hubert Pirkle, John Hoefs, Sunita Lohiya, Vinh Trong Ngo – 1 September 1985 – In a Californian institution for the mentally retarded, surveillance by autopsy of all deaths (n = 138) identified three cases of hepatocellular carcinoma. Hepatocellular carcinoma cases occurred in young (mean age = 26 years) male carriers of HBsAg and were not associated with cirrhosis. They were of the nonfibrolamellar oncocytic type and were rapidly fatal. Hepatocellular carcinoma incidence in HBsAg carriers was estimated to be 246 times greater than United States males.

Hepatitis B virus DNA, HBeAg and delta infection during the course from acute to chronic hepatitis B virus infection

Kim Krogsgaard, Jan Aldershvile, Peter Kryger, Poul Andersson, Jens Ole Nielsen, Bengt Göran Hansson, The Copenhagen Hepatitis Acuta Programme – 1 September 1985 – The presence of hepatitis B virus DNA in serum was determined in 57 unselected patients during the course from acute to chronic hepatitis B infection. Forty‐six (81%) patients were hepatitis B virus DNA‐positive in the first available serum sample. Generally, hepatitis B virus DNA was cleared before or at the same time as HBeAg, but in two patients (4%), hepatitis B virus DNA could be demonstrated after HBeAg clearance.
