The principal components of a variety of mucous secretions have been found to be glycoproteins, many of mol.wt. 500000 or more (Gottschalk, 1972). We have isolated the glycoprotein from pig colonic mucus and examined its structure in order to compare it with that of the well-characterized glycoprotein of the gastric mucus from the same species (Snary & Allen, 1971 ; Allen, 1977). Mucosal scrapi...

34 Nesfatin-1, a novel hypothalamic peptide, inhibits nocturnal feeding behavior and 35 gastrointestinal motility in rodents. The effects of nesfatin-1 on gastrointestinal secretory 36 function, including gastric acid production, have not been evaluated. Nesfatin-1 was injected 37 into the 4 intracerebral ventricle (4V) of chronically cannulated rats to identify a nesfatin dose 38 sufficient to...

Glycoconjugates expressed on gastric mucosa play a crucial role in host-pathogen interactions. The FUT2 enzyme catalyzes the addition of terminal alpha(1,2)fucose residues, producing the H type 1 structure expressed on the surface of epithelial cells and in mucosal secretions of secretor individuals. Inactivating mutations in the human FUT2 gene are associated with reduced susceptibility to Hel...

STUDY OBJECTIVES To determine the effect of feeding tube position (gastric vs small bowel) on adequacy of nutrient delivery and feeding complications, including microaspiration, in critically ill children. DESIGN Randomized controlled trial. SETTING Pediatric ICU in a university teaching hospital. PATIENTS Seventy-four critically ill patients < 18 years of age receiving mechanical ventila...

Noninvasive positive-pressure ventilation (NPPV) might be superior to conventional mechanical ventilation (CMV) in patients with acute exacerbations of chronic obstructive pulmonary disease (AECOPDs). Inefficient clearance of respiratory secretions provokes NPPV failure in patients with hypercapnic encephalopathy (HE). This study compared CMV and NPPV combined with a noninvasive strategy for cl...

Gastric Ulceration in the Adult Gastric ulceration syndrome (GUS), a complicated and multi-factorial problem, is a common disorder of the stomach of mature horses. Horses that are turned out to pasture and are not involved in work have normal stomachs as do most horses used for light work or pleasure (Murray 1994). In recent years the widespread nature of this disorder has gained increased reco...

BACKGROUND/AIMS Cochinchina momordica seed extract (SK-MS10) has a gastric protective effect. We aimed to assess the effect of SK-MS10 on gastric acid secretion with morphologic changes in the aged rat. METHODS Acid secretions were evaluated in the male F344 rats of four different ages (6-, 31-, 74-week, and 2-year). The 31-week-old rats were divided to three groups and continuously administe...

Colonization of the digestive tract has been supposed to be the source of many hospital-acquired infections, especially nosocomial pneumonia. To assess the relationship between oropharyngeal and gastric colonization and subsequent occurrence of nosocomial pneumonia, we prospectively studied 86 ventilated, intensive care unit (ICU) patients. Oropharyngeal or gastric colonizations were detected a...
