An Investigation into the Role of P-Glycoprotein in the Intestinal Absorption of Repaglinide: Assessed by Everted Gut Sac and Caco-2 Cell Line
The present study aimed at exploring the potential of the P-glycoprotein (P-gp) transporters as a barrier to the repaglinide (REG) epithelial permeability. In-vitro intestinal absorption models, the everted gut sac, and Caco-2 cell line, were used to study the possible role of P-gp in intestinal transport of REG. In the everted gut sacs, apparent permeability coefficients showed cargo concentra...

متن کاملBilirubin and Urobilins in Germfree, Ex-germfree, and Conventional Rats
No urobilinogens are present in the feces or urine of germfree rats. After contamination of germfree animals with feces from conventional animals the exgermfree rats produced urobilins to the same extent as conventional animals on the same diet. The negative urobilin test turned positive in germfree animals infected with a single Clostridium-like microorganism isolated from the intestinal conte...
متن کاملMucus in Intestinal Contents of Germfree Rats
The fecal excretion of total nitrogen and of total hexosamines has been determined in germfree and conventional rats. Germfree rats excreted more hexosamines than the conventional rats, while no difference in the nitrogen excretion was found. Infection of the germfree rats with a normal flora resulted in a temporarily increased excretion of hexosamines and nitrogen over a period of 2 to 3 days ...
متن کاملMucus in Intestinal Contents of Germfree Rats* by Goran
One of the differences between animals reared under germfree conditions and conventional 1 animals is the considerable enlargement of the germfree cecum. I t has been shown that the gross enlargement of the cecum is due to an increase in the amount of the cecal contents as well as to an increase in the weight of the cecal wall. When germfree animals were contaminated with a normal intestinal fl...
