DNBS/TNBS Colitis Models: Providing Insights Into Inflammatory Bowel Disease and Effects of Dietary Fat
Published on: February 27, 2014
Abstract:
The size and composition of the bile salt pool has been measured in patients with untreated coeliac disease and in control subjects. The total bile salt pool was markedly increased in coeliac patients, the average being 9.2 grams compared with 3.1 grams in controls. Taurocholate synthesis was normal, consistent with its enlarged pool and prolonged half-life. Half-life and pool size were significantly correlated. The composition of the bile salt pool was virtually identical in the two groups. Our findings suggest that as the enterohepatic circulation is slowed by gallbladder inertia, so hepatic surveillance of pool size is diminished.

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
