The distribution of the goblet cells, Paneth cells and Brunner's glands in duodenum of adult one humped camels (Camelus dromedarius)‎

الملخص EN

The purpose of this study was to unveil the light microscopic morphology and distribution of the goblet cells, paneth cells and Brunner's glands in duodenum of the adult one humped camels.The present study was carried out on fifteen duodeni,these have been removed from healthy adult male camels aging (4-5) years, immediately after slaughtering.

The specimens were divided into equal five parts, named as following (first ,second,third,fourth and fifth) .Ten specimens (1cm3) was taken from different regions of each part of the duodenum; and fixed into 10% formalin and Bouin's solution approximately 24 hours, then treating by routine histological processing .

The sections are stained by H & E, PAS and V.G.

stains.

Goblet cells, paneth cells and alveoli of the Brunner's glands were counted ,used ten microscopic fields of each part of the duodenum.

Mean ± Standard error were calculated.The duodenal wall was composed of four tunicae (mucosa, submucosa,muscularis and serosa or adventitia).Goblet cells,shown as globular shaped cells dispersed among the columnar cells in the epithelium that lined the villi and crypts of Lieberkuhn in the tunica mucosa of the duodenum, and take positive reaction with(PAS) and the Paneth cells, were granular cells in crypts of Lieberkuhn only.

The present study revealed the mean number of goblet and paneth cells in crypts of Lieberkuhn were increased in last parts of camel duodenum toward the jejunum.

Brunner’s glands, appeared as branched tubuloalveolar glands, found in the lamina propria of first, second and third parts and in submucosa of each duodenal part.

The mean number of the alveoli of the Brunner's glands in submucosa of the first part were more than that in other parts, and decreased toward last parts, but absent in last sections of fifth part toward the jejunum.

Conclusion : The present study revealed reversed relation between number of the goblet and paneth cells with the Brunner’s glands in the duodenum toward the jejunum for neutralize of the ingesta and contributing to the immunity of duodenum.
