background & aim:  non-steroidal anti-inflammatory drugs (nsaids) are commonly used in clinical medicine. the adverse effects they produce in the gastrointestinal tract however, often limit their utility. oxidative stress has been shown to occur in the small intestine in response to the oral administration of indomethacin. in view of this, the effect of thyme essential oil, an agent with an...

BACKGROUND The spread of the invasive snail Pomacea canaliculata is expanding the rat lungworm disease beyond its native range. Their toxic eggs have virtually no predators and unusual defenses including a neurotoxic lectin and a proteinase inhibitor, presumably advertised by a warning coloration. We explored the effect of egg perivitellin fluid (PVF) ingestion on the rat small intestine morpho...

This experiment was conducted to evaluate the effects of supplemental L-arginine (ARG) in reduced-protein diets on cardiopulmonary performance and intestinal morphology in the broilers reared at high altitude. A total of 156 day-old male broilers were randomly assigned to 3 treatments and 4 replicates of 13 chicks and reared up to 42 days of age. Treatment groups were designed as a normal-prote...

Small intestinal morphology and function were assessed in 82 patients with dermatitis herpetiformis, 51 of whom were taking a normal diet and 31 a gluten free diet. Methods used were histopathological evaluation of jejunal mucosal biopsy specimens, quantitation of intraepithelial lymphocytes, cellobiose/mannitol permeability test, tissue disaccharidase values, serum antigliadin antibodies, and ...

The objective of this study was to determine the effects of age and diet on intestinal morphology and large bowel fermentative end-product concentrations in healthy dogs. Small intestinal villus width, height, and area, and small intestinal and colonic crypt depth were measured. Large bowel digesta samples were analyzed for ammonia, SCFAs, and branched-chain fatty acids (BCFAs). SCFAs are consi...

It has been suggested that maternal nutrition during gestation is involved in an offspring's intestinal development. The aim of this study was therefore to evaluate the effects of maternal energy on the growth and small intestine development of offspring. After mating, twenty gilts (Large White (LW) breeding, body weight (BW) at 135.54 ± 0.66 kg) were randomly allocated to two dietary treatment...

To determine the influence of increasing levels of supplemental ruminally undegraded intake protein (UIP) on visceral organ weights, growth, cell proliferation, and morphology, 20 mature ewes of mixed breeding were fed a 6.55% CP grass hay:straw mixture (40:60) and assigned to one of four supplemental treatments. Supplements were control (no supplement) and low, medium, and high levels of UIP. ...
