Abstract

Some parts of the intestinal tract, which involve in secretion of certain hormones that regulate significant organs of the body, the purpose of the research to study the site endocrine cell in small intestine & colon in goat, the present study included 5 specimens of intestine goat from the ages ranging from 1-5 years to determine the site endocrine cells in the parts of intestine examined via using immunohistochemistry procedure material.It was used immunohistochemistry textile technology and (ChromograinnA), which is a special detector Endocrine intestinal cells, three types of hormones. Immune chemical assessment in the mucous layer duodenum and the presence of hormones, 'glucose insulin tropic polypeptide(GIP) results showed (GIP) and glucagon-like peptide2 (GLP-2)' in epithelial cells collection along the internal axis of the villi , the cells appeared triangular or slender shape indicate that they are enter ondocrine cell chemical immunological consequences for many of the sections shown note chromogranin A detector chiefly for intestinal endocrine cells, the cells that have hormones (GIP) , glucose insulin tropic polypeptide and glucagon peptide GLP-1) containing this reagent representative confirm the site of these cells, a gastric endocrine cells ,the result attendance that presence the GIP was in the duodenal region higher than ilium & jejunum while the GLP-1/ GIP-2 was clear to a large extent in colon and obtrusive in ilium .

Abstract

In the current study, fifteen rabbits from both sexes have been used to identify the anatomical and histological structure of abdominal aorta. Ten rabbits used for anatomical study. The celiac artery was a first branch of the abdominal aorta (A.A.) and then followed by the cranial mesenteric artery, right and left renal arteries, lumbar artery, caudal mesenteric artery and finally, it gives off two common iliac trunks. The splenic artery was the larger branch of the celiac artery and the cranial mesenteric artery was the greater branches of A.A. of rabbits. The lumber branches were very clear and a raised from the ventral aspect of A.A. There were numerous of jujenal arteries arises from a cranial mesenteric artery and the testicular or ovarian arteries sometimes originated above or below caudal mesenteric artery. Five rabbits used for a histological study of the abdominal aorta of three regions at the (celiac artery. renal artery. and common iliac artery). The abdominal aorta has consisted of three layers from internal to external tunica intima, T. media, and T. adventitia. The intima consists of a single layer of endothelial cells and it's the thinnest layer while T. media composed of numerous elastic laminae in a circular arrangement and it's the thickest layer finally T. adventitia was the outermost layer consist of smooth muscle fibers, collagen fibers, few elastic fibers, and vasa vasorum. The aim of this study to exposure the normal appearance of abdominal aorta by used the using corrosion cast & latex techniques and histological studies.
