Diamine oxidase activity levels in anorexia nervosa.
OBJECTIVE Anorexia nervosa (AN) patients often experience gastrointestinal complications caused by their malnutrition. We hypothesized that intestinal integrity is disturbed in AN. Therefore, the objective of the present study was to investigate serum diamine oxidase (DAO) activity, which is considered to be a clinical indicator of the integrity of the intestinal mucosa, in AN patients. METHO...
متن کاملCarboxymethyl starch/alginate microspheres containing diamine oxidase for intestinal targeting
The association of carboxymethyl starch (CMS) and alginate is proposed as a novel matrix for the entrapment of bioactive agents in microspheres affording their protection against gastrointestinal degradation. In this study, the enzyme diamine oxidase (DAO) from white pea (Lathyrus sativus) was immobilized by inclusion in microspheres formed by ionotropic gelation of CMS/alginate by complexation...
متن کاملNutrients regulate diamine oxidase release from intestinal mucosa.
Diamine oxidase is continuously released from the intestinal mucosa and carried to the circulation by the lymphatics. The effect of nutrients on this release was examined. Rats were prepared with duodenal and intestinal lymph cannulas. Test mixtures of lipid emulsions containing triolein, oleic acid, or tricaprylin and solutions of carbohydrate and protein were infused into the duodenum. The en...
متن کاملBacterial translocation secondary to small intestinal mucosal ischemia during cardiopulmonary bypass. Measurement by diamine oxidase and peptidoglycan.
OBJECTIVES To demonstrate that small intestinal mucosal ischemia occurs during cardiopulmonary bypass by measuring serum diamine oxidase activity, an index of small intestinal mucosal ischemia, in perioerative patients undergoing cardiovascular surgery with and without cardiopulmonary bypass. METHODS Twelve successive patients who underwent coronary artery bypass grafting with cardiopulmonary...
متن کاملDiamine oxidase and cadaverine metabolism.
We have recently presented evidence that diamine oxidase is rcsponsiblc for a portion of the metabolism of histamine in several species (1, 2). This evidence is largely based on the alteration of histamine metabolism produced by compounds which are known to inhibit diamine oxidase in vitro. The inhibitors used were isonicotinylhydrazine (3) and aminoguanidine. The latter is reported to be the m...
