Hepatic hemodynamics and oxygen consumption in alcoholic fatty liver assessed by organ‐reflectance spectrophotometry and the hydrogen clearance method

Akinori Kasahara, Norio Hayashi, Kazuhei Kurosawa, Yutaka Sasaki, Nobuhiro Sato, Takenobu Kamada – 1 January 1986 – Hepatic blood flow and estimated hepatic oxygen consumption were studied in rats treated chronically with ethanol by organ‐reflectance spectrophotometry and the hydrogen clearance method.

Portal venous‐esophageal luminal pressure gradient in cirrhosis

Pierre Reding, Daniel Urbain, André Grivegnee, Daniel Frere – 1 January 1986 – The portal venous‐esophageal luminal pressure gradient may be more important than the absolute portal venous pressure in explaining hemorrhages caused by esophageal varices. A continuous recording of portal venous pressure and the esophageal luminal pressure enabled the authors to study the gradient between these pressures in 12 cirrhotic patients with varices of different size and under different circumstances, in particular inspiration, expiration, coughing and a Valsalva maneuver.

Effects of ethanol on experimental hepatocarcinogenesis

Akira Takada, Jinichi Nei, Shujiro Takase, Yoshiro Matsuda – 1 January 1986 – Although primary hepatoma is not very frequent in alcoholics, the incidence of hepatoma in cases of hepatitis B infection combined with heavy alcohol drinking is high. In the present study, the effects of chronic alcohol administration onthe development of chemicalinduced hepatic cancer in rats were analyzed. In 70% hepatectomized Wistar strain male rats, asingle dose (1 mg per 100 gm body weight) of diethylnitrosamine was injected intraperitoneally.

Hemagglutination and immunofluorescence studies on polymerized human serum albumin binding activity in chronic hepatitis B virus infection

Ignacio Mora, Juan Carlos Porres, Carlos Hernández Guio, Julia Gutiez, Vicente Carreño – 1 January 1986 – The binding activity of polymerized human serum albumin was determined in 202 HBsAg carriers. The presence of polymerized human serum albumin receptor sites was tested by hemagglutination and differentiated from antihuman albumin antibodies by immunofluorescence, isolation of IgG and IgM fractions and testing of HBsAg anti‐HBs immune complexes. A granular pattern with anti‐HBs was specific for polymerized human serum albumin receptor sites as demonstrated with purified HBsAg.

Effect of volume expansion on hemodynamics, capillary permeability and renal function in conscious, cirrhotic rats

Carlos Caramelo, Dolores Fernandez‐Muñoz, Juan C. Santos, Alicia Blanchart, Diego Rodriguez‐Puyol, José M. López‐Novoa, Luis Hernando – 1 January 1986 – General and splanchnic hemodynamics (radioactive microspheres), renal function, spontaneous and histamine‐mediated vasopermeability and albumin distribution space were studied in conscious control and nonascitic cirrhotic rats, before and after a moderate and sustained saline infusion (3% of body weight per 30 min + repletion of urinary losses).

Effect of propranolol on hepatic and systemic hemodynamics in dogs with chronic bile duct ligation

Bernard Willems, Jean‐Pierre Villeneuve, P.‐Michel Huet – 1 January 1986 – Propranolol has been reported to reduce portal and wedged hepatic vein pressures in man and may be useful for the prevention of variceal bleeding. However, its mechanism of action remains unclear. We have examined the effect of propranolol on the systemic and hepatic circulations in dogs with chronic bile duct ligation and secondary biliary cirrhosis. Underanesthesia, eight dogs received four increasing doses of propranolol as an i.v. bolus followed by continuous infusion.

Expression of β2−microglobulin on hepatocytes in acute and chronic type B hepatitis

Yukihisa Nagafuchi, Professor Peter J. Scheuer – 1 January 1986 – β2−Microglobulin display was examined in 131 liver biopsies from patients with acute and chronic type B hepatitis, using an indirect immunoperoxidase method. Enhanced expression of β2−microglobulin on hepatocyte membranes was observed in patients with acute hepatitis, chronic active hepatitis with moderate to severe activity and cirrhosis, when compared with normal liver. In acute hepatitis, β2−microglobulin‐positive hepatocytes were mainly observed in perivenular areas in association with bridging necrosis.
