Histological and histochemical study of proventriculus, istmus and gizzard in Guinea fowl (Numida meleagris)

In Digestive system in birds is the most important body for their growth. Since histochemistery and histometrical in connection with the stomach, there is little information isthmus and gizzard Guinea fowl 5 adult male chickens were prepared. Samples are first anesthetized and then anatomy proventriculus of the three parts (elementary, middle, and end), isthmus and gizzard two field (body and cranial, caudal bag). Then the samples of were taken according to the method of tissue processor sections stained with hematoxylin - eosin, Masson trichrome and coloring mixture passes Alciane were studied. The results showed that in the stomach mucosa contains numerous folds worn by simple columnar epithelium. Toward the end of the columnar cells epithelial the proventriculus of height decreases were seen in high cuboidal. Histometrical results in a primary third the height of the cells in the (24/46 ± 5/40 μm), the middle third (11/58 ± 1/70 μm) and a terminal third (9/34 ± 1/42 μm) was determined. The gizzard inner surface is covered pseudo keratinized by it was short columnar epithelium. Tunica submucosa Thick in the body (460/6 ± 25/94 μm) and the cranial, caudal bag (283/64 ± 76/68 μm) were determined. There is not in the gizzard muscular mucous.
