Metabolism, pharmacokinetics, and activity of a new 6-fluoro analogue of ursodeoxycholic acid in rats and hamsters.

abstract：:Random fecal alpha 1-antitrypsin levels were determined in 34 patients, 24 with Crohn's disease, and 10 "controls" having diarrheal illnesses not associated with intestinal protein loss, in an effort to evaluate its usefulness as a measure of Crohn's disease intestinal activity. In the control group, all alpha 1-antit...
