Christopher B. O'brien, John R. Senior, Renu Arora‐Mirchandani, Ashok K. Batta, Gerald Salen – 1 November 1991 – We investigated the effects of once‐daily oral administration of 10 mg/kg ursodeoxycholic acid (generic name, ursodiol) on elevated serum enzyme activities, bilirubin, cholesterol, bile acids and symptoms in patients with primary sclerosing cholangitis.
Sumiko Nagoshi, Tomoaki Tomiya, Yuzuru Sato, Yuji Oka, Itsuro Ogata, Kenji Fujiwara – 1 November 1991 – When epidermal growth factor was given to rats after partial hepatectomy, hepatic putrescine content was significantly increased at 4, 6 and 10 hr compared with control rats. Ornithine decarboxylase activity was also increased.
Stephan Krahenbuhl, Eric P. Brass – 1 November 1991 – Energy metabolism is abnormal in patients and experimental animals with liver cirrhosis. To help better understand the abnormalities, fuel homeostasis and carnitine metabolism were studied in fed and 24‐hr‐starved rats with secondary biliary cirrhosis induced by bile duct ligation for 4 wk. Plasma ketone body concentrations were decreased by 67% in starved, bile duct–ligated rats compared with control rats.
Henry H. Hsu, Teresa L. Wright, Daniel Luba, Mary Martin, Stephen M. Feinstone, Gabriel Garcia, Harry B. Greenberg – 1 November 1991 – Although hepatitis C infection has been clearly demonstrated to be transmitted through blood products or blood contamination, most cases of sporadic hepatitis C infection are unassociated with parenteral risk factors, and it is unclear how infection might be acquired by nonparenteral means. One potential mode of nonparenteral transmission is through body secretions.
Juan Armendariz‐Borunda, Jerome M. Seyer, Arnold E. Postlethwaite, Andrew H. Kang – 1 November 1991 – Conditioned media from cultured Kupffer and mononuclear macrophagic cells obtained 48 hr after CCl4 administration to rats contains chemotactic factors for human skin fibroblasts and human monocytes. The chemotactic mediator for fibroblasts was approximately 17 kD and was more prominent at early stages of culture. It induced a dose‐dependent chemotactic response in fibroblasts.

Takashi Tanaka, Yoshihiro Sukegawa, Shuhei Nishiguchi, Tetsuo Kuroki, Kenzo Kobayashi, Isao Matsui‐Yuasa, Shuzo Otani, Takashi Toda, Takeyuki Monna – 1 October 1991 – The effects of a single ethanol administration on ornithine decarboxylase induction, polyamine metabolism and DNA synthesis in rat liver after partial hepatectomy were studied. Ethanol given 1 hr before partial hepatectomy at the dose of 2, 3 or 5 gm/kg body wt inhibited the increase in ornithine decarboxylase activity and that in the putrescine level in the liver 4 hr after partial hepatectomy.
Franco O. Ranelletti, Mauro Piantelli, Everardo Zanella, Arnaldo Capelli, Attilio M. Farinon – 1 October 1991 – Cytosolic receptors for estrogen and progesterone were assayed in 50 gallbladders from 29 women and 21 men who had cholecystectomies because of choleithiasis. High‐affinity (equilibrium dissociation constant, KD = 0.46 ± 0.23 nmol/L of 24 cases) estrogen receptors were detected in 20 of 29 gallbladders from women (range = 1.6 to 32 fmol/mg protein; mean ± S.D. = 10.9 ± 8.1), whereas in men only 4 of 21 specimens contained detectable estrogen receptors.
