Future therapeutic approaches for inflammatory bowel diseases.

abstract：:The intracellular pH (pHi) of isolated hamster intestinal cells was determined with three techniques: the null-point method with digitonin, the distribution of the weak acid 5,5-dimethyloxazolidine-2,4-dione, and the trapped fluorescent indicator 2',7'-bis(carboxyethyl)-5(6)-carboxyfluorescein. In physiologic saline, ...
