The mechanism of elevated alkaline phosphatase activity after bile duct ligation in the rat

Shakuntla Seetharam, Norman L. Sussman, Tsugikazu Komoda, David H. Alpers – 1 May 1986 – Alkaline phosphatase activity in the liver and intestine increases after bile duct ligation, reportedly by increased enzyme synthesis. To ascertain the mechanism of this increased synthesis in the absence of a cDNA clone encoding the enzyme, we have estimated the concentration of liver and intestinal alkaline phosphatase mRNA by translational analysis. Monospecific antiserum to rat placental alkaline phosphatase was raised.

HLA class I antigens on the hepatocyte membrane during recovery from acute hepatitis B virus infection and during interferon therapy in chronic hepatitis B virus infection

Massimo Pignatelli, Jenny Waters, Dave Brown, Andrew Lever, Sten Iwarson, Zsuzsa Schaff, Robert Gerety, Howard C. Thomas – 1 May 1986 – In a chimpanzee model of acute type B hepatitis, at the time of onset of hepatitis B virus replication and before the development of immunity to hepatitis B virus, interferon is present in the plasma. This is followed by an increase in the display of HLA class I, but not class II proteins, on the hepatocyte membrane.

Gastric bleeding in portal hypertension: Inflammatory or congestive?

I. James Sarfeh, A. Tarnawski – 1 May 1986 – This paper reports the incidence and natural history of macroscopic gastritis in a series of 127 consecutive patients with portal hypertension of various aetiologies. Gastritis was observed endoscopically in 65 patients (51%) and was of two main types. Twenty eight patients had severe or persistent gastritis which caused clinically significant bleeding on 80 occasions and accounted for 25% of the bleeds from all sources. The remainder had mild gastritis.

Effect of experimental liver disease on the utilization for protein synthesis of orally administered α‐ketoisocaproate

Santiago Muñoz, Mackenzie Walser – 1 May 1986 – The incorporation of orally administered 1‐14C‐α‐ketoisocaproate into the leucine of proteins in rats was compared with the incorporation of [3H]leucine itself administered simultaneously and expressed as a ratio, R. This ratio in whole body protein has been shown to be approximately equal to the nutritional efficiency of α‐ketoisocaproate as a dietary substitute for leucine.

ARA‐AMP in chronic HBV hepatitis: Follow‐up too short or too long?

Albert J. Czaja – 1 May 1986 – A randomised controlled trial was conducted in 29 HBV carriers who had been HBs and HBe antigen positive for more than six months. Fifteen patients were treated with ARA‐AMP 10 mg/kg/ day given as intramuscular injections 12 hours apart for five days followed by 5 mg/kg/day for 23 days. The 14 controls received no treatment. Serum HBV‐DNA polymerase, and HBV‐DNA decreased in all patients during therapy. Six treated patients lost serum HBV‐DNA polymerase, HBV‐DNA and HBeAg, HBsAg concentrations decreased, and five developed anti‐HBe.

Ultrastructural immunocytochemical analysis of lymphocytes infiltrating bile duct epithelia in primary biliary cirrhosis

Gotaro Yamada, Ichinosuke Hyodo, Kazuo Tobe, Motowo Mizuno, Takashi Nishihara, Toshinari Kobayashi, Hideo Nagashima – 1 May 1986 – Subpopulations of lymphocytes in portal areas, especially infiltrating bile duct epithelia were analyzed by light and electron microscopy using indirect peroxidaselabeled antibody method and monoclonal antibodies against pan‐T (Leu 1), cytotoxic/suppressor T (Leu 2a), helper/inducer T (Leu 3a) and natural killer/K (Leu 7) and suppressor T (Leu 15) cells in liver biopsy specimens from four patients with primary biliary cirrhosis.

Sodium excretion in advanced cirrhosis: Effect of expansion of central blood volume and suppression of plasma aldosterone

Kathleen M. Nicholls, Michael D. Shapiro, Rudiger Kluge, Hsaio‐Min Chung, Daniel G. Bichet, Robert W. Schrier – 1 March 1986 – Sodium excretion in 13 patients with decompensated cirrhosis was measured under baseline conditions of water loading (n = 13) and during conditions designed to improve effective blood volume including: head‐out water immersion alone (n = 13); norepinephrine infusion alone (n = 6), and combined norepinephrine and head‐out water immersion (n = 6).
