Hyperglycemia reduces gallbladder emptying and plasma hormone secretion to modified sham feeding and regular feeding

Sybrand Y. de Boer, Ad A. M. Masclee, Wai Fan Lam, Jaap Schipper, Jan B. M. J. Jansen, Cornelius B. H. W. Lamers – 1 June 1993 – The purpose of this study was to investigate the effect of acute stable hyperglycemia on gallbladder motility, plasma cholecystokinin level and pancreatic polypeptide secretion. Gallbladder emptying in response to modified sham feeding and regular feeding was determined in six healthy subjects on two separate occasions during normoglycemia (serum glucose = 5 mmol/L) and during hyperglycemia (serum glucose = 15 mmol/L).

Expression of the terminal protein of hepatitis B virus is associated with failure to respond to interferon therapy

Graham R. Foster, Robert D. Goldin, Andrew Hay, Michael J. McGarvey, George R. Stark, Howard C. Thomas – 1 May 1993 – The terminal protein domain of the hepatitis B viral polymerase can inhibit the cellular response to interferon. To clarify the clinical relevance of this inhibitory effect, we examined the expression of terminal protein in liver biopsy specimens from patients with chronic hepatitis B infection.

Monoclonal antibody against the CD18 adhesion molecule stimulates glucose uptake by the liver and hepatic nonparenchymal cells

Abraham P. Bautista, Zoltan Spolarics, Hartmut Jaeschke, C. Wayne Smith, John J. Spitzer – 1 May 1993 – Neutrophils and macrophages play an important role in the body's microbicidal defense and have been implicated in the induction of tissue injury in reperfusion, endotoxemia and septic shock. Cellular host defense is accompanied by enhanced glucose use. In this study we examined the effect of monoclonal antibody 1F12 on in vivo glucose use by selected tissues and hepatic phagocytes.

Drug targeting to the liver with bile acids: THE “trojan horse” resurrected?

Dirk K. F. Meijer – 1 May 1993 – Bile acids are selectively taken up from portal blood into the liver by specific transport systems in the hepatocyte plasma membrane. Therefore, studies were performed to evaluate the potential of bile acids as shuttles to deliver drugs specifically to the liver. The alkylating cytostatic drug chlorambucii and the fluorescent prolyl‐4‐hydroxylase inhibitor 4‐nitrobenzo‐2‐oxa‐1,3‐diazol‐β‐Ala‐Phe‐5‐oxaproline‐Gly were covalently linked via an amide bond to 7α, 12α,‐dihydroxy‐3β‐(ω‐aminoalkoxy)‐5‐β‐cholan‐24‐oic acid.

Lack of mother‐to‐infant transmission of hepatitis C virus in human immunodeficiency virus–seronegative women: A prospective study with hepatitis C virus RNA testing

Françoise Roudot‐Thoraval, Jean‐Michel Pawlotsky, Valérie Thiers, Lionel Deforges, Pierre‐Paul Girollet, François Guillot, Christiane Huraux, Pascale Aumont, Christian Brechot, Daniel Dhumeaux – 1 May 1993 – The published risk of mother‐to‐infant transmission of hepatitis C virus varies according to the population studied and the tests used. In a prospective study we used the polymerase chain reaction to assess the risk of vertical transmission of hepatitis C virus in an unselected population of women uninfected by human immunodeficiency virus.

Frequent loss of heterozygosity on chromosome 22 in hepatocellular carcinoma

Kazuhiro Takahashi, Jiro Kudo, Hiromi Ishibashi, Yasuhiko Hirata, Yoshiyuki Niho – 1 May 1993 – We investigated 24 hepatocellular carcinomas in Japan to find loss of heterozygosity with 15 polymorphic DNA markers that detect allelic losses at specific chromosome loci. Loss of heterozygosity on chromosomes 10q, 17p and 22q was detected in 3 of 12 (25%), 9 of 21 (43%) and 5 of 15 (33%) informative cases of hepatocellular carcinoma, respectively.

Functional inactivation of neutrophils with a Mac‐1 (CD11b/CD18) monoclonal antibody protects against ischemia‐reperfusion injury in rat liver

Hartmut Jaeschke, Anwar Farhood, Abraham P. Bautista, Zoltan Spolarics, John J. Spitzer, C. Wayne Smith – 1 May 1993 – The role of neutrophil CD11b/CD18 (Mac‐1) adhesion proteins in the pathogenesis of hepatic reperfusion injury was investigated in an experimental model. Male Fischer rats were treated with a CD11b monoclonal antibody or an isotype‐matched IgM control antibody and subjected to 45 min of hepatic ischemia followed by 24 hr of reperfusion.
