Regenerative changes in hepatic morphology and enhanced expression of CYP2B10 and CYP3A during daily administration of cocaine

P Pellinen, F Stenback, A Kojo, P Honkakoski, H V Gelboin, M Pasanen – 1 March 1996 – The effects of daily cocaine administration for up to 14 days were studied in terms of hepatic morphology and the expression of cytochrome P450 (CYP) enzymes in the mouse liver. Daily intraperitoneal doses of 60 mg/kg of cocaine for 3 days induced severe hepatocellular necrosis in the pericentral zone and decreased activities of CYP1A2, CYP2A4/5, and CYP2Cx.

Carbon tetrachloride‐induced cirrhosis in rats: Influence of the acute effects of the toxin on glucose metabolism

F Mion, A Géloén, E Agosto, Y Minaire – 1 March 1996 – In animal models, conflicting results on the effect of cirrhosis on glucose metabolism have been reported. The use of various toxins as well as differences in experimental protocols may be responsible for these controversial data. However, differences may be also be explained by the fact that glucose metabolism has been evaluated following different time intervals after cessation of the toxic injury.

Adaptive response of the enterohepatic circulation of bile acids to extrahepatic cholestasis

R Dumaswala, D Berkowitz, J E Heubi – 1 March 1996 – Experimental cholestasis induced by ligation of the common bile duct results in morphological and functional changes in the rat hepatocyte. The aim of this study was to evaluate the adaptive response of the transport process involved in the enterohepatic circulation of bile salts to obstructive cholestasis. Male Sprague‐dawley rats with common bile duct ligation were killed after 48 and 72 hours. Portal and systemic blood and duodenal aspirates were collected.

Changes in liver core temperature during preservation and rewarming in human and porcine liver allografts

Martin Hertl, Todd K. Howard, Jeffrey A. Lowell, Surendra Shenoy, P. Robert C. Harvey, Steven M. Strasberg – 1 March 1996 – Liver core temperature during organ procurement, storage, and rewarming has not been reported in human orthotopic liver transplantations (OLT). We have shown in the rat that optimal temperature for liver storage is not 4°C but 0°C to 1°C. Therefore, a study was undertaken in humans and in pigs to determine the pattern of temperature change during OLT.

Superselective arterial embolization in the liver transplant recipient: A safe treatment for hemobilia caused by percutaneous transhepatic biliary drainage

Kenneth L. Croutch, Roy L. Gordon, Ernest J. Ring, Robert K. Kerlan, Jeanne M. Laberge, John P. Roberts – 1 March 1996 – Transcatheter arterial embolization is widely used to treat life‐threatening iatrogenic hemobilia, although in the transplanted liver its use has only been reported in two cases. To evaluate more fully whether transcatheter embolization is safe and effective in transplant recipients, we retrospectively reviewed eight cases of severe hemobilia. These occurred after 128 percutaneous transhepatic biliary drainage procedures performed during a 6‐year period.

Hepatitis C virus in body fluids after liver transplantation

Stephen H. Caldwell, Michael Sue, James H. Bowden, Rolland C. Dickson, Carolyn J. Driscoll, Paul Yeaton, William C. Stevenson, Michael B. Ishitani, Christopher S. McCullough, Timothy L. Pruett, Mark A. Lovell – 1 March 1996 – Recurrence of hepatitis C virus (HCV) after liver transplantation is common and is associated with high blood levels of HCV RNA. Higher blood levels of HCV may promote body fluid expression of the virus. We tested 152 body fluid specimens from 33 patients with chronic hepatitis C, 21 of whom had undergone prior liver transplantation.

Involvement of calcium in macrophage leukotriene release during experimental cirrhosis

L Alric, E Pinelli, G Carrera, J P Vinel, M Beraud, M Duffaut, J P Pascal, B Pipy – 1 March 1996 – The aim of the present study was to assess the mechanism of 5‐lipoxygenase metabolites (LT) secretion by peritoneal macrophages in rats wih CC14 induced cirrhosis. After stimulation with calcium ionophore A23187 or opsonized zymosan, [3H] arachidonic acid labeled macrophages from cirrhotic rats presented a significantly greater secretion of LT than macrophages from healthy controls.

Liver grafts can be preserved overnight

Jean Vix, Philippe Compagnon, Jean‐Paul Beller, Daniel Jaeck, Philippe Wolf, Karim Boudjema – 1 March 1996 – The introduction of University of Wisconsin solution has made liver transplantation a semi‐elective procedure. However, many studies have suggested that cold storage must not exceed 12 hours to avoid ischemic‐type biliary complications, to reduce the incidence of primary nonfunction and to improve graft and patient survival. The aim of this study was to compare the function of livers transplanted as soon as possible after the liver was harvested and those preserved overnight.
