It is well-known that prostaglandin (PG) synthetase inhibitors such as aspirin and indomethacin induce gastrointestinal ulcer both in experimental animals and humans. In addition, it has been reported that PG levels in the plasma and gastric juice of patients with ulcer are significantly lower than these levels in healthy subjects (1). On the other hand, PGE type PGs and their analogs are effec...

Several substances, including glutamine and propionic acid but in particular butyric acid, have been proposed to be important for colonic health. β-Glucans lead to the formation of comparatively high amounts of butyric acid, and germinated barley foodstuff obtained from brewer's spent grain (BSG), containing high amounts of β-glucans and glutamine, has been reported to reduce the inflammatory r...

In present paper, the recovery of propionic acid from aqueous phase by reactive extraction was studied using tri-n-butyl phosphate (TBP) in petroleum ether. Extraction using pure diluent was found to be poor. Using the mixture of extractant-diluent the extraction was significantly improved. Results were presented in terms of distribution coefficient, equilibrium complexation constant, loading r...
