UK-9040, a derivative of the antihistamine triprolidine, is a potent gastric secretory inhibitor. Given orally to dogs it reduced gastric acid, pepsin and volume output in response to food, insulin, histamine, N-methyl histamine, and pentagastrin. Doses of 6-36 mg/kg administered orally four to five hours before the secretagogues produced a dose-dependant and up to 100% inhibition in the output...

Traditionally drugs used in peptic ulcer have been directed mainly against a single luminal damaging agent i.e. hydrochloric acid and a plethora of drugs like antacids, anticholinergics, histamine H2-antagonists etc. have flooded the market. An increase in 'aggressive' factors like acid and pepsin is found only in a minority of peptic ulcer patients. These factors do not alter during or after s...

Eugenia jambolana (Jamun) fruit has been reported to give soothing effect on human digestive system. Present study includes the effect of ethanolic extract of seeds of E. jambolana (EJE) against gastric ulcers induced by 2 h cold restraint stress (CRS), aspirin (ASP, 200 mg/kg, 4 h), 95% ethanol (EtOH, 1 ml/200 g, 1 h) and 4 h pylorus ligation (PL) in rats. To ascertain the mechanism of action ...

BACKGROUND Recent data suggest that during mechanical ventilation the lateral-horizontal patient position (in which the endotracheal tube is horizontal) decreases the risk of ventilator-associated pneumonia, compared to the recommended semi-recumbent position (in which the endotracheal tube slopes downward into the trachea). We tested the feasibility of the lateral-horizontal patient position, ...

Animal models are needed to assess novel proteins produced through biotechnology for potential dietary allergenicity. Currently proposed rodent models evaluate sensitizing potential of food extracts or proteins following parenteral administration or oral administration with adjuvant. However, food allergy requires not only the potential to induce immunoglobulin (Ig) E but also the capacity to a...

This study aimed to understand the structural devolution of 10% w/w rennet-induced (RG) and transglutaminase-induced acid (TG) gels in H2O D2O under vitro gastric conditions with without pepsin. The real-time structure at a nano- (e.g. colloidal calcium phosphate (CCP) micelle) micro- (gel network) level was determined using ultra-small (USANS) small-angle neutron scattering (SANS) electron mic...

This paper presents evidence for the existence in extracts from porcine non-antral gastric tissue of a peptide capable of causing substantial rises of plasma immunoreactive gastrin levels in a dose dependent manner and of stimulation of gastric acid and pepsin secretion. Obtained data show that the peptide is basic and that its gastrin releasing properties are at least partially resistant to at...
