Although the histology of the intestinal tract of Crocodylus niloticus is touched on in overall studies on reptilian intestinal tract, a more comprehensive light microscopical study on this area is lacking. Specimens for histological examination were taken from the duodenum, the jejunum, the ileum and the rectum. The data obtained revealed that the mucosa is thrown into folds and simple, slight...

Octodon degus is a desert rodent of northern Chile, adapted to survive with a limited supply of water. This rodent has a high degree of fecal dehydration, related to colon water absorption. With the hypothesis that aquaporins (AQPs) might be present in the colon epithelium of O. degus and involved in fluid absorption, we studied colon water absorption in vivo and the distribution of AQPs and Na...

BACKGROUND Ectopic crypts, defined as abnormally positioned crypts that have lost their orientation toward the muscularis mucosae, have been suggested to be the best defining histologic feature of traditional serrated adenoma (TSA). However, the significance of ectopic crypt formation (ECF) in the distinction between TSA and conventional adenoma (CA) has rarely been studied. METHODS We design...

cer mortality in Taiwan, with more than 4,500 people dying of this disease in 2009. Malignant colorectal polyps represent the majority of early colorectal cancers. The term “malignant polyp” refers to a macroscopically benign appearing adenoma in which the invasive carcinoma is detected after histologic examination of the resected specimen. The muscularis mucosa must be breached to be defined a...

In this study the morphology, conventional glycohistochemistry and ultrastructure of adult rainbow trout (Oncorhynchus mykiss) stomach is reported. For purpose, belonging to 10 female trout, weighting ~ 500 ± 20 gr 32 2.50 cm long, were collected processed. Oncorhynchus mykiss has a siphonal stomach, with J letter shape, showing descending portion (cardiac region), an ascendant one (pyloric con...

The aim of the study was to evaluate gastroprotective effect dry extracts from roots and rhizomes Ferulopsis hystrix in ethanol-induced gastropathy. Materials methods . studies were carried out on 68 white Wistar rats. Ethanol-induced gastropathy simulated by a single intragastric administration ethanol dose 10 ml/kg. Animals experimental groups received medicinal forms F. : I – decoction volum...
