Effect of short‐term ethanol administration on lorazepam clearance

Anasticio M. Hoyumpa, Rashmi Patwardhan, Michael Maples, Paul V. Desmond, Raymond F. Johnson, Alicia P. Sinclair, Steven Schenker – 1 January 1981 – The disposition of chlordiazepoxide (Librium®) and diazepam (Valium®), compounds which are initially degraded by oxidative processes, differs from that of oxazepam (Serax®) and lorazepam (Ativan®), drugs which are inactivated by conjugation with glucuronic acid. Liver disease and cimetidine impair the elimination of the former agents, but not the latter two benzodiazepines.

Identification of integrated hepatitis B virus DNA sequences in human hepatocellular carcinomas

David A. Shafritz, Michael C. Kew – 1 January 1981 – DNA extracts from hepatocellular carcinomas of 13 patients from South Africa were examined for hepatitis B virus (HBV) DNA sequences by molecular hybridization using [32P]‐labeled recombinant, cloned, and purified HBV‐DNA. Eight patients were HBV carriers as demonstrated by the presence of hepatitis B surface antigen (HBsAg) in their serum, and each of these patients had HBV‐DNA sequences in hepatocellular carcinoma tissue. Five patients who were not HBsAg carriers, did not have HBV‐DNA in their tumors.

Proline trapping in granulomas, the site of collagen biosynthesis in murine schistosomiasis

Michael A. Dunn, Sam Seifter, Penelope K. Hait – 1 January 1981 – Proline, a critical substrate for collagen synthesis, is increased in liver undergoing fibrosis. In mice with schistosomiasis, the incorporation of proline into collagen occurs within liver granulomas. To study the interaction of liver cells and granulomas in the development of fibrosis, we assayed the enzymes that catalyze the formation and degradation of proline in isolated granulomas and liver.

Liver histopathology in chronic common bile duct stenosis due to chronic alcoholic pancreatitis

Angelos Afroudakis, Neil Kaplowitz – 1 January 1981 – The liver histopathology in 40 liver biopsies from 24 patients with verified chronic common bile duct stenosis due to chronic alcoholic pancreatitis has been reviewed code‐blinded. This represents an 8% prevalence of this complication in approximately 300 patients with alcoholic pancreatitis screened biochemically for alkaline phosphatase >two‐fold for >1 month. The majority were anicteric with no symptoms other than from acute exacerbations of chronic pancreatitis.

Protection by antibiotics against experimental focal cholangitis produced in mice by a schistosomicidal isothiocyanate

Robert P. Batzinger, Ernest Bueding, Hans Popper – 1 January 1981 – Oral administration to mice of high doses of 4‐isothiocyano‐4′nitrodiphenylamine (amoscanate), a potent antischistosomal drug, produced focal necrotizing lesions of the large intrahepatic and extrahepatic bile ducts and the gallbladder. Coadministration of erythromycin and, to a somewhat lesser degree, of paromomycin, markedly reduced the effects of amoscanate on the biliary tract.

Idiopathic neonatal iron storage involving the liver, pancreas, heart, and endocrine and exocrine glands

Sidney Goldfischer, Harold W. Grotsky, Chung‐Ho Chang, Errol L. Berman, Robert R. Richert, Sushama D. Karmarkar, Jacqueline O. Roskamp, Rachel Morecki – 1 January 1981 – Autopsy studies of two infants, one a newborn, the other 4 months old, revealed massive amounts of iron in lysosomes of hepatocytes and pancreatic acinar cells. Iron, which had been transported across the placenta, accumulated in the same cell types as in adults with primary and secondary hemochromatosis.
