Christopher Babbs, Najib Y. Haboubi, Jonathan M. Mellor, Alexander Smith, Brenda P. Rowan, Thomas W. Warnes – 1 May 1990 – There is increasing interest in the changes of the endothelial lining of the hepatic sinusoids during the development of chronic liver disease. In this study we looked for evidence of hepatic sinusoidal endothelial cell transformation and basement membrane production in patients with primary biliary cirrhosis.

Hajime Takikawa, Naoyo Sano, Tohru Narita, Masami Yamanaka – 1 May 1990 – The reason for the discrepancy between bile flow and biliary bile acid excretion during ursodeoxycholate infusion in rats is unknown. We found that ursodeoxycholate‐glucuronide is formed during ursodeoxycholate infusion at higher doses. Ursodeoxycholate infusion (1 to 3 μmol/min/100 gm body weight) for 90 min caused marked hypercholeresis, and the previously reported discrepancy between bile flow and biliary bile acid excretion was observed when bile acid concentrations were measured by regular enzymatic methods.

Malcolm M. Berenson, Cathy Gunther, Wade S. Samowitz, David J. Bjorkman – 1 May 1990 – The effect of bile acids on the formation of biliary thrombi in protoporphyrin‐induced cholestasis was determined by perfusing isolated rat livers with taurocholate, chenodeoxycholate and ursodeoxycholate with and without protoporphyrin. Protoporphyrin‐induced reduction of bile flow was similar in the presence of each bile acid.

Jen‐Hwey Chiu, Cheng‐Po Hu, Wing‐Yiu Lui, Szecheng J. Lo, Chungming Chang – 1 May 1990 – Hepatocytes, known as polarized epithelial cells, are composed of sinusoid, basolateral and bile canalicular domains. Each domain contains proteins specific for it. Our studies indicate that the well‐differentiated human hepatoma cell lines HepG2 and HuH‐7 formed bile canaliculi in tissue culture, whereas the poorly differentiated hepatoma cell lines HA22T/VGH and SK‐HEP‐1 did not.

H. Dariush Fahimi, Alfred Voelkl, Styliani H. Vincent, Ursula Muller‐Eberhard – 1 May 1990 – The abundant heme‐binding protein of the liver, probably identical with Z‐protein or liver fatty acid‐binding protein, has an apparent molecular weight of 14,000 Da and is presumably involved in the intracellular transport of a variety of compounds. The cellular and subcellular distribution of HBP in the liver was studied in adult male and female rats by postembedding immunocytochemistry using the protein A‐gold technique.

Georg Wensing, Robert A. Branch – 1 May 1990 – The onset of sodium retention in phenobarbital/carbon tetrachloride‐induced cirrhosis in rats is preceded by a linear decrease in hepatic function as assessed by the aminopyrine rate constant of elimination. Sodium retention occurs when liver function decreases below a critical aminopyrine rate constant of elimination threshold of 1 min− × 10−3.

Ian R. Wanless – 1 May 1990 – Nodular regenerative hyperplasia is defined by he‐patocellular nodules distributed throughout the liver in the absence of fibrous septa between the nodules. Most reports have been single cases so that the prevalencend clinical significance of nodular regenerative hyperplasia is uncertain. In this study, the hepatic histology of 2,500 consecutive autopsies was reviewed.
