Detection of hepatitis B virus DNA in paraffin‐embedded liver tissues in chronic hepatitis B or non‐A, non‐B hepatitis using the polymerase chain reaction

Michiko Shindo, Tadao Okuno, Ken Arai, Masayuki Matsumoto, Makoto Takeda, Kei Kashima, Mamoru Shimada, Yoshiaki Fujiwara, Yoshihiro Sokawa – 1 January 1991 – We developed a polymerase chain reaction assay for the direct detection of hepatitis B virus in paraffinembedded liver tissue and applied this assay to determine whether hepatitis B virus DNA exists in livers with chronic hepatitis non‐A, non‐B.

Omeprazole and aryl hydrocarbon hydroxylases: Should we be worried?

J. C. Kolars, D. K. Turgeon, P. B. Watkins – 1 January 1991 – Diaz and colleagues have carefully studied the effects of omeprazole on the expression of cytochrome P‐450 in primary cultures of human hepatocytes. When omeprazole was added to the culture medium in varying concentrations, there was an increase in P‐450IA2 protein and mRNA concentrations, an increase in de novo synthesis of P‐450IA2 protein, and an increase in microsomal catalytic activities characteristic of P‐450IA2 (phenacetin deethylase and acetanilide hydroxylase).

Selective dopamine DA1 stimulation with fenoldopam in cirrhotic patients with ascites: A systemic, splanchnic and renal hemodynamic study

Antoine Hadengue, Richard Moreau, Yannick Bacq, Christophe Gaudin, Alain Braillon, Didier Lebrec – 1 January 1991 – We studied the effects of fenoldopam, a selective dopamine DA1 agonist on systemic and splanchnic hemodynamics, renal blood flow and sodium excretion in 12 patients with alcoholic cirrhosis and ascites. Hepatic, azygos and renal veins were catheterized before and after intravenous administration of fenoldopam, 0.05 μg/kg/min for 1 hr and increased to 0.1 μg/kg/min for another hour.

Distribution of cholesterol between vesicles and micelles in human gallbladder bile: Influence of treatment with chenodeoxycholic acid and ursodeoxycholic acid

Staffan Sahlin, Per Thyberg, Jon Ahlberg, Bo Angelin, Kurt Einarsson – 1 January 1991 – The present study aimed at determining the relative distribution of cholesterol between the vesicular and micellar phases in gallbladder bile of gallstone patients (n = 23) and gallstone‐free subjects (n = 7). Nine of the gallstone patients were treated with chenodeoxycholic acid and seven were treated with ursodeoxycholic acid, 15 mg/kg/day, for 3 wk before cholecystectomy.
