Jorge L. Poo, Alain Braillon, Antoine Hadengue, Christophe Gaudin, Didier Lebrec – 1 March 1992 – The hemodynamic responses to terbutaline – a selective β2‐adrenoceptor agonist – were studied in conscious normal rats and in conscious rats with secondary biliary cirrhosis. Compared with those of normal rats, dose‐response curves in cirrhotic rats indicated significantly decreased reactivity in arterial pressure and heart rate. Half‐maximal effective dose was not significantly different between the two groups.

John Olynyk, Phillip Williams, Andrew Fudge, Steven Pulbrook, Rikki Kerr, Malcolm MacKinnon, Pauline Hall – 1 March 1992 – The potential application of fine‐needle aspiration liver biopsy in the documentation of hepatic iron overload has been assessed in iron‐loaded rats. Fineneedle aspiration and standard liver biopsy specimens were obtained from three groups of animals supplemented with oral and parenteral iron for 2 to 6 mo. The mean dry weights of standard and fine‐needle biopsy specimens were 7.41 ± 0.77 (± S.E.M.) and 0.57 ± 0.54 mg, respectively.

Satoru Todo, Thomas E. Starzl, Andreas Tzakis, Keith J. Benkov, Frantisek Kalousek, Takeyori Saheki, Kyuichi Tanikawa, Wayne A. Fenton – 1 March 1992 – Hyperammonemia, abnormalities in plasma amino acids and abnormalities of standard liver functions were corrected by orthotopic liver transplantation in a 14‐day‐old boy with carbamyl phosphate synthetase‐I deficiency and in a 35‐yr‐old man with argininosuccinic acid synthetase deficiency. The first patient had high plasma glutamine levels and no measureable citrulline, whereas citrulline values were markedly increased in Patient 2.

Patricia Sheiner, Wilfred de Majo, Gary A. Levy – 1 March 1992 – Background. When administered early after an overdose of acetaminophen, intravenous acetylcysteine prevents hepatic necrosis by replenishing reduced stores of glutathione. How acetylcysteine improves the survival of patients with established liver damage induced by acetaminophen, however, is unknown. This study was undertaken to determine whether the beneficial effect of acetylcysteine under such circumstances could be due to enhancement of oxygen delivery and consumption.

P. Aiden McCormick, Graham L. Kaye, Lynda Greenslade, Fabrizio Cardin, Kenneth E. F. Hobbs, Neil McIntyre, Andrew K. Burroughs – 1 March 1992 – It is not clear which therapy should be used in patients with bleeding esophageal varices that are not controlled by emergency sclerotherapy. This is a high‐risk group with reported mortality rates of between 70% and 90%. We report our 7‐yr experience with staple transection of the esophagus in this patient group. Of 168 patients (280 bleeding episodes) treated with sclerotherapy, 22 had emergency staple transection for failure to control bleeding.

Hiroaki Okamoto, Fumio Tsuda, Atsuhiko Machida, Eisuke Munekata, Yoshihiro Akahane, Yoshiki Sugai, Kazuo Mashiko, Takehiro Mitsui, Takeshi Tanaka, Yuzo Miyakawa, Makoto Mayumi – 1 February 1992 – Immunoassays were developed to detect antibodies against oligopeptides deduced from the putative core gene of hepatitis C virus, and their performances were compared with that of the commercial immunoassay for antibodies against the product of nonstructural regions of hepatitis C virus (anti‐C100‐3).

J. Michael Henderson, Gregory J. Mackay, Michael Hooks, Judith L. Chezmar, John R. Galloway, Thomas F. Dodson, Michael H. Kutner – 1 February 1992 – This study measured cardiac output before and 1 or 2 yr after orthotopic liver transplantation in 23 patients. Cardiac output was measured by thermodilution before transplantation and by first‐pass radionuclide angiocardiography at follow‐up.

Sun‐Mee Lee, Mark G. Clemens – 1 February 1992 – This study was done to determine the relationship between microsomal lipid peroxidation during hepatic ischemia/reperfusion and alteration in cytochrome P‐450–dependent drug metabolism. Rats were pretreated with α‐tocopherol to inhibit lipid peroxidation or with vehicle (soybean oil) and then subjected to 60 min no‐flow hepatic ischemia in vivo. Control animals were time‐matched sham‐ischemic animals. After 1, 5 or 24 hr of reperfusion, liver microsomes were isolated and cytochrome P‐450 and mixed function oxidases were studied.
