Lipid peroxidation and antioxidant defense systems in rat liver after chronic ethanol feeding

Tateo Kawase, Shinzo Kato, Charles S. Lieber – 1 November 1989 – The effects of chronic ethanol feeding on hepatic lipid peroxidation, ascorbic acid, glutathione and vitamin E levels were investigated in rats fed low or adequate amounts of dietary vitamin E. Hepatic lipid peroxidation was significantly increased after chronic ethanol feeding in rats receiving a low‐vitamin E diet, indicating that dietary vitamin E is an important determinant of hepatic lipid peroxidation induced by chronic ethanol feeding.

Augmentation of the natriuretic response to atrial natriuretic factor in cirrhosis

Alexander L. Gerbes – 1 November 1989 – The effects of atrial natriuretic factor (ANF) on splanchnic hemodynamics and renal function in portal hypertensive models are described incompletely. Furthermore, ANF‐induced vasodilatation and hypotension may limit the assessment of its own renal physiological effects. We infused ANF (human ANF 102‐126) to anesthetized portal vein‐ligated rats, a model with prehepatic portal hypertension. Arterial pressure was reduced by 17%, but portal pressure was unaffected.

Tissue‐specific activity of heterologous viral promoters in primary rat hepatocytes and Hep G2 cells

Fang Xian‐Jun, Armand Keating, Jean de Villiers, Morris Sherman – 1 November 1989 – In preparation for studies using gene transfer, we have identified transcriptional control elements which are active in primary rat hepatocytes. We used plasmids which were constructed so that the promoter or enhancer of interest initiated transcription of the bacterial chloramphenicol acetyltransferase (CAT) gene.

Reduced‐size orthotopic liver transplantation: Use in the management of children with chronic liver disease

Jean C. Emond, Peter F. Whitington, J. Richard Thistlethwaite, Estella M. Alonso, Christoph E. Broelsch – 1 November 1989 – Reducing the size of a liver for use in a recipient smaller than the donor is one way to reduce mortality before orthotopic liver transplantation in children because of the scarcity of pediatric organ donors. In this report, we review the results of this approach over the past 2 years, during which we have used reduced‐size orthotopic liver transplantation routinely in small children.

Hepatic drug clearance in chronic liver disease: Can we expect to find a universal, quantitative marker of hepatic function?

Denis J. Morgan, Richard A. Smallwood – 1 November 1989 – Blood clearance of antipyrine, indocyanine green, and galactose were measured to evaluate the alterations of effective hepatic blood flow and hepatic intrinsic clearances in chronic liver diseases. Galactose blood clearance, which may be taken as effective hepatic blood flow, decreased by approximately 30% in patients with cirrhosis (12.49 ± 0.76 ml/min/kg; mean ± SE; n = 17) compared with normal subjects (18.17 ± 1.03 ml/min/kg; n = 5).

Hepatic denervation alters hemodynamic response to hemorrhage in conscious rats

Yves Ozier, Alain Braillon, Christophe Gaudin, Dominique Roulot, Antoine Hadengue, Didier Lebrec – 1 October 1989 – We investigated the effect of liver denervation on cardiovascular homeostasis. Three days after surgical denervation of the liver, hemodynamic studies (radioactive microsphere method) were conducted in conscious rats. The efficacity of the liver denervation procedure was confirmed by a significant decrease in norepinephrine content in various lobes of the liver. Liver denervation did not affect either systemic or splanchnic resting hemodynamics.

The differentiation of cholesterol and pigment gallstones

Dieter Jüngst – 1 October 1989 – Gallbladder biles and stones were obtained at 116 cholecystectomies for symptomatic gallstone disease. All 33 patients younger than 50 years had cholesterol stones, whereas 40% of the older patients had pigment stones. We compared the reliability of three different bile tests for the differentiation between cholesterol and pigment stone patients.
