The objective of this study was to investigate the size of the small and large intestine in postnatal development of Mus musculus mice. The gut was obtained from 2-, 4-, 6-, and 12-week-old animals. The morphometric analysis was performed at microscopic level. Measurements and calculations included dimensions of villi (height, diameter) and their number per 1 mm(2) surface area in the proximal,...

Food intake of rats increases during pregnancy. This requires changes in the structure of the small intestine to absorb additional food. The aim of the present study was to investigate the morphological changes in the layers of small intestine in rats during pregnancy. Duodenum, jejunum and ileum of 18 pregnant Sprague-Dawley rats (day 7, 14 and 21 of pregnancy) were collected. Villous height a...

in a parasitic study on five sharks (carcharhinus macloti) caught from the iranian coasts of persian gulf, two of five sharks appeared to have nematode in their intestine. using light microscopy, the nematode was identified as acanthocheilus rotundatus. a. rotundatus  is characterised by 3.3-4.5 cm in length, semithick cuticle, small lips, semicircular and tri-lobed pseudolabia (not offset from...

  Objective(s): The aim of the present study is to determine the effect of Chloramphenicol (CAP) on rat liver and small intestine. Effect of phenobarbital (PB) on CAP toxicity was also investigated.   Materials and Methods:   Rats were received CAP at doses of 0, 200, 400 and 600 mg/kg. Another group was pretreated with 80 mg/kg PB 30 min prior to administration of various doses...

the effects of different levels of whole cottonseed (wcs) on feedlot performance and morphology of small intestine were studied in a completely randomized design with four diets containing 0, 4, 8 and 16 percent wcs on 20 chaal male lambs for 90 days. the metabolisable energy and proteins contents of rations were equal. number and dimensions of different types of villi and depth of crypt gland ...

In this study, random sampling conducted and 90 individuals of Persian sturgeon having 3-5g weight, collected by trawling in 3 earthen ponds and 15 individuals having 10-20g weight, collected by small net in 3 fiberglass Vans. After recording of biometrical characteristics, the intestine and rearing water were cultured on TSA medium. Gram staining and complementary tests were conducted. In orde...

this experiment was carried out to determine the effect of different levels of sumac powder (rhus coriaria l.) in the ration with and without probioenzyme on the performance and parameters of blood cholesterol and triglycerides of japanese quail, from the age of 8 to 42 days, based on a completely randomized design, containing 8 treatment, 3 repetion, and 5 chicks of quail with both sexes in ea...
