چکیده

زمینه مطالعه: شیپور استاش کانال استخوانی-غضروفی است که حفره صماخی را به ناحیه بینی ای حلق متصل میکند. هیچ تحقیق آناتومیکی و بافت شناسی بر روی این عضو در گاومیش انجام نشده است. هدف: مطالعه آناتومیکی و بافت شناسی شیپور استاش در گاومیش بالغ بعنوان اطلاعات پایه ای برای شناخت این عضو مورد استفاده قرار خواهد گرفت. روش کار: تعداد 8 عدد سر گاومیش بالغ نر و ماده از کشتارگاه تهیه شد و شیپور استاش آنها مورد مطالعه آناتومیکی قرار گرفت، سپس نمونه بافتی اخذ گردید. نمونه ها به روش های H&E برای مطالعه عمومی، Verhoff برای رشته های الاستیک،PAS برای کربوهیدراتها و Masson's Trichrome برای رشته های کلاژن رنگ آمیزی شدند. نتایج: یافته های آناتومیکی نشان داد شیپور استاش سفید رنگ و به شکل لوله ای قیفی، بدون انحنا و تماما غضروفی است و در هر دو جنس دارای ساختمان مشابه می باشد. نتایج بافت شناسی و هیستوشیمی نیز نشان داد اپیتلیوم شیپور استاش گاومیش استوانه ای شبه مطبق مژه دار است و در بعضی نواحی نیز به صورت سنگفرشی مطبق میباشد. غضروف در ابتدا از نوع الاستیک و سپس از نوع غضروف شفاف می باشد. غدد موجود در شیپور استاش گاومیش از نوع موکوسی بوده و بافت لنفاوی را به طورواضح میتوان در دهانه حلقی به شکل لوزه لوله شنوایی غیرفولیکولار یافت. نتیجه گیری نهایی : یافته های حاصل از این تحقیق میتواند بعنوان اطلاعات پایه ای آناتومی و بافت شناسی شیپور استاش در گاومیش قابل ارائه باشد.

چکیده [English]

BACKGROUND: The Eustachian tube is an osteocartilaginous channel connecting the tympanic cavity with the nasopharynx. There is no anatomical and histological research performed on this organ in buffalo. OBJECTIVES: Anatomical and histological study of Eustachian tube in buffalo will be useful for basic knowledge of this organ. METHODS: For this study 8 adult male and female buffalo's head were provided from slaughter house and their Eustachian tube were studied anatomically, then tissue samples were obtained and paraffin sections were prepared for using of staining methods such as H&E (for general study), Verhoff (for elastic fibers), PAS (for carbohydrates) and Masson's Trichrome Stainning Kit (for collagen fibers). RESULTS: Anatomical results showed Eustachian tube was white and funnel- like tube, no curve and structurally supported by cartilage and in both sexes they had the same structure. Histological and Histochemical results showed the epithelium of Eustachian tube in buffalo is pseudostratified ciliated columnar and in some regions of the Eustachian tube epithelium was stratified squamous. In the first portion of Eustachian tube cartilage was elastic and then eustachian tube cartilage was hyaline. The glands of Eustachian tube in buffalo were mucous and non folicular tubal tonsil could be found around the pharyngeal opening with obviously lymphoid tissue. CONCLUSIONS:. The results of this research can be used as the basic anatomical and Histological knowledge in buffalo..
