The effect of diosmectite on intestinal permeability changes in acute diarrhea was measured during a double-blind placebo-controlled trial carried out in 59 Gabonese children aged 5-35 months. Intestinal permeability tests (IPTs), measuring the urinary elimination of orally administered lactulose and mannitol at a dosage of 1 g/10 kg each, were performed(More)
An intestinal permeability test analyzing the differential urinary elimination of lactulose and mannitol orally ingested at the same dosage was carried out first in fasting condition, then combined with specific food ingestion, in 17 children with clinical symptoms of irritable bowel syndrome (IBS). Foods were selected based on a suggestive clinical history(More)
An intestinal permeability test (IPT) analysing the mannitol (M) and lactulose (L) clearances and the L/M ratios was performed in 15 children followed for celiac disease, before the onset of exclusion diet, during the gluten-free diet and after the reintroduction of gluten. The results showed a significant increase of the L/M ratios under normal diet, with(More)
Intestinal permeability was evaluated by measuring the excretion of two orally absorbed (0.1 g/kg of weight) nonmetabolizable markers, mannitol and lactulose. In 39 controls, the lactulose/mannitol urinary ratio (L/M ratio) was 2.45 +/- 1.01% during fasting and remained stable after food ingestion. In 12 children with cow's milk-sensitive enteropathy under(More)
Intestinal permeability to macromolecules was studied by measuring differential urinary elimination of two orally ingested non-metabolizable sugars of different molecular size, mannitol and lactulose. In 25 control children, mannitol and lactulose urinary elimination were 16.30 +/- 5.77% and 0.33 +/- 0.10% of ingested dose, respectively, with a mean(More)
The intestinal mucosa has a certain degree of "porosity", which allows some molecules and macromolecules that are not subject to active transport, to cross the intestinal wall and enter the blood circulation. This permeability of the intestinal mucosa, which depends mostly on the size of the molecule and the state of the mucosa, can be studied with the(More)
Heat-shock protein 70 (HSP70) plays a crucial role as intracellular cytoprotectant and molecular chaperone. A phenomenon of heat stress (HS) leads to production of these proteins that could be beneficial to cells during cryopreservation, which is also a stressful process for the cell. This study aimed to evaluate the protective effect of exposure of bovine(More)
In infants, food allergies are usually manifested by digestive symptoms and the most commonly involved antigens are cow's milk proteins. Although the full range of clinical manifestations of cow's milk protein sensitivity may occur as soon as birth, enteropathy is the most common pattern. As the infant grows, cow's milk antigens lose their predominance as(More)
