background: the incidence of caustic ingestion injuries in developed countries has been decreasing, while it still remains a great concern in developing countries including iran. in this study we focused on alkali esophageal injuries in children which occur frequently in southern iran, due to both, unsafe products and unfamiliarity of families with the alkali consumption hazards. methods : in a...

Liquid food can likely cause accidental ingestion in patients with dysphagia. This study proposes a handheld stirrer-type rotational viscometer that be used the kitchen or at meals for A novel is proposed considering rotation speed of stirrer inversely proportional to viscosity fluids stirred. We adopt sensorless control strategy. use small brush-type DC motor, which functions as rotary actuato...

The rapid development of the gastrointestinal tract posthatch has been described; however, little information exists concerning the development of the small intestine in the prehatch period. The present study examined the morphological, cellular, and molecular changes occurring in the small intestine toward the end of the incubation period by examining the expression of intestinal genes that co...

Previous findings in rats and in human vegetarians suggest that the plasma carnitine concentration and/or carnitine ingestion may influence the renal reabsorption of carnitine. We tested this hypothesis in rats with secondary carnitine deficiency following treatment with N-trimethyl-hydrazine-3-propionate (THP) for 2 weeks and rats treated with excess L-carnitine for 2 weeks. Compared to untrea...

The chronic ingestion of raw or undercooked kidney beans (Phaseolus vulgaris L.) is involved in the pathogenesis of multiple organ dysfunction; the underlying mechanisms are still poorly understood. The objective of this study was to assess the gavage effects of a raw Beldia bean variety on the brush border disaccharidase activities in the jejunal mucosa of Wistar rats. Twenty young adult male ...

The domestic cat (Felis catus), a carnivore, naturally eats a very low carbohydrate diet. In contrast, the dog (Canis familiaris), a carno-omnivore, has a varied diet. This study was performed to determine the expression of the intestinal brush border membrane sodium/glucose cotransporter, SGLT1, sweet receptor, T1R2/T1R3, and disaccharidases in these species adapted to contrasting diets. The e...

The morphology of the rat duodenum after chronic treatment with 15% (v/v) ethanol and 4% (v/v) pentanol was studied. Male Wistar rats of experimental groups were given ethanol and pentanol for 15 weeks with food and fluid freely available. Ethanol-15% and 4% pentanol-fed rats showed a significantly reduced fluid and food intake as compared with control rats. The study of the mucosa indicated th...
