Mitotic activity and hence cell turnover has been abolished by x-irradiation with 1,000 r. in segments of the rat's gut. The whole stomach, the ascending colon, and 5 cm. of jejunum and ileum were irradiated and the changes observed histologically up to three days. Cessation of cell turnover in the small intestine is followed by cell death and desquamation within 24 hours, leading to denudation...

the present study was carried out to evaluate the effects of vegetable fat sources and additives on performance and morphological parameters of the small intestine of arain broiler chickens. birds were randomly used in a 2×3 factorial arrangement of dietary treatments included two fat sources (canola or pumpkin seed) and three additives (without additive, 0.1 g/kg probiotic and 0.15 g/kg virgin...

objective(s): to investigate the efficacy of interleukin 11 (il-11) towards the high dose methotrexate (hdmtx)-concurrent rat small intestinal mucositis and its impacts on the proliferation of the human t-lymphoblastic leukemia (cem) cell line. materials and methods:95 wistar rats were randomly divided into five groups, the normal control group (a), the methotrexate (mtx) control group (b), the...

Incubation in vitro of the intestine of the hamster and guinea pig with 5 mM sodium cholate and with 2 mM sodium deoxycholate and sodium chenodeoxycholate resulted in significant morphological changes compared with control incubations. Generally, no major differences were observed between proximal and distal small intestine or between the species used. Only when guinea pig intestine was incubat...

There is an increased risk of small bowel adenocarcinoma in patients with coeliac disease compared with the normal population. It has been suggested that adenocarcinoma of the small intestine in coeliac disease arises through an adenoma-carcinoma sequence but there has been only one reported case of a small bowel adenoma in a patient with coeliac disease. We report three additional cases of a s...

Two trials involving a total of 56 pigs were conducted to examine the effects of weaning at 7 d of age (trial 1) and of energy intake level and length of post-weaning underfeeding period (trial 2) on small intestinal (SI) development and morphometry. At 3 d after weaning, weight of the SI and mucosa (g/kg body weight) and villous height along SI were reduced by 20, 36 and 41%, respectively, com...

Background: Small intestine and peripheral organs are the main organs for digestion and absorption in the gastrointestinal tract. OBJECTIVES: To investigate effects of different levels of Vitamin E and Selenium on growth performance and small intestine morphometry in Japanese quail. METHODS: A total of 405 mixed sex Japanese quails were randomly allocated into 9 experimental groups by 3×3 facto...

Objective(s): To investigate the efficacy of interleukin 11 (IL-11) towards the high dose methotrexate (HDMTX)-concurrent rat small intestinal mucositis and its impacts on the proliferation of the human T-lymphoblastic leukemia (CEM) cell line. Materials and Methods: 95 Wistar rats were randomly divided into five groups, the normal control group (A), the methotrexate (MTX) control group (B), th...
