Brush border membrane-bound digestive enzymes such as disaccharidases (lactase, sucrase, and maltase), leucine aminopeptidase N, and alkaline phosphatase were measured in jejunum from pigs experimentally infected with porcine epidemic diarrhea virus (PEDV). Three piglets from the infected and
BACKGROUND
Maltase-glucoamylase enzyme plays an important role in starch digestion. Glucoamylase deficiency is reported to cause chronic diarrhea in infants, but its role in dyspeptic children is unknown.
METHODS
Glucoamylase and other disaccharidase specific activities were assayed from duodenal
Two experiments were conducted to determine intestinal disaccharidase activity in 1-day-old commercial turkey poults inoculated with astrovirus. Small intestinal samples were collected on days 0.5, 1, 3, and 7 postinoculation (PI) in Expt. 1 and on days 7, 10, and 14 PI in Expt. 2 and evaluated for
Nucleic acid synthesis in tissues of rapid growth is preferentially done using dietary purines and pyrimidines via the salvage pathway. In the case of a low protein intake, dietary nucleotides may be semiessential for cell replication of gut, lymphocytes, and bone marrow, and especially in those
BACKGROUND
In Indonesia, the proportion of daily carbohydrate intake is approximately 60-80%. A number of small bowel disorders can result in the impairment of absorption and enzyme deficiency. Chronic diarrhea is common in Indonesia.
METHODS
Thirty-four functional dyspeptic patients with an
The chronic diarrhea observed in young malnourished infants that is sensitive to dietary glucose and other carbohydrates is associated with variable degrees of patchy mucosal villous atrophy. To explore intrinsic mucosal function in the pathogenesis of this alimentary intolerance, we have conducted
Histologic assessment as well as information about the disaccharidase activity of the small intestinal mucosa can be useful in the management of patients with small intestinal mucosal damage. In an effort to determine whether the degree of small intestinal mucosal damage would be reflected in a
OBJECTIVE
To determine whether human milk accelerates the recovery rate of injured small intestinal mucosa.
METHODS
Randomized, controlled trial.
METHODS
County and nonprofit, private urban hospitals.
METHODS
Moderately to severely malnourished infants less than 6 months of age who required
Two therapeutic regimens were compared in 16 infants with protracted diarrhea and malnutrition. Eight patients were treated with total parenteral nutrition given via a central vein (group A); the remaining eight patients received a combination of dilute parenteral nutrients given in a peripheral
Investigations by scanning electron microscopy into changes of surface morphology of small bowel mucosa in children with chronic nonspecific diarrhea are reported. The study population comprised 56 patients, ranging in age from 5 months to 7 years; 65% were between 10 and 28 months old, and 64% of
Thirty infants with intractable diarrhea of infancy (IDI) underwent small bowel biopsies in order to determine the extent and duration of small intestinal mucosal injury. The onset of the persistent diarrhea occurred prior to 3 months of age and continued for an average of 48 days prior to
Unexpected, urgent, sometimes painful bowel movements after eating are common complaints among adults. Without a clear etiology, if pain is present and resolves with the movements, this is usually labeled "irritable bowel syndrome-diarrhea" based solely on symptoms. If this symptom-based approach is
The effects of carbohydrate intake on jejunal disaccharidases in rats with chronic mannitol-induced, osmotic diarrhea were studied. Weanling rats were force-fed 5 ml/100 g of body weight of water of 20% mannitol (w/v 1300 mOsm) daily for up to 14 days. Diets containing 70% of either starch, sucrose,
46 of 74 children with chronic diarrhea of unknown etiology between the ages of 44-627 days were studies. They were assigned, by single randomization, to 3 dietary treatments: a) cow's milk, b) a sucrose- free (SED-S), and c) a sucrose containiNG semi-element diet (SED+S), for 15 days. The authors
