چکیده مقاله :
هدف از این مطالعه بررسی ساختار هیستوآناتومی و رادیولوژیکی دستگاه تنفسی کبک چوکار (Alectoris chukar) بود. در این مطالعه از 8 کبک چوکار بالغ (4 کبک نر و 4 کبک ماده) با میانگین وزنی550 گرم استفاده شد. برای مطالعات رادیولوژیکی از کبک‌های تحت مطالعه رادیوگراف‌هایی با نما‌های جانبی چپ و راست، پشتی - شکمی و شکمی - پشتی تهیه شد. سپس ریه‌ها و نای از لحاظ آناتومیکی و توپوگرافیکی مورد بررسی قرار گرفتند. متعاقب بررسی‌های آناتومیکی، مطالعات بافت‌شناسی انجام گرفت. براساس نتایج این مطالعه در رادیوگراف‌های شکمی – پشتی، ریه‌های چپ و راست در طرفین ستون مهره‌ها قابل مشاهده بودند. در نمای جانبی، ریه‌ها در موقعیت پشتی و در قسمت قدامی حفره سلومی قرار داشته و بهتر قابل مشاهده بود. در این نما ریه‌ها در موقعیت پشتی قلب قرار گرفته بودند و به دلیل وجود پارابرونشیولها، ظاهر لانه زنبوری از خود نشان می‌دادند. نای به وضوح از ناحیه حلق تا محل دوشاخه شدن سیرینکس قابل مشاهده بود. یافته‌های ماکروسکوپیک نشان داد که ریه‌ها فاقد لوب بوده و فضای پلور وجود نداشت. به علت فقدان پرده جنب، ریه‌ها از طریق بافت فیبری به بافت‌های اطراف متصل شده بودند. سطح پشتی ریه‌ها محدب و هم شکل انحنای دنده‌ها بود. سطح احشایی مقعر و به سمت قلب و کبد قرار داشت و محل ورود برونش‌های اصلی راست و چپ بود. ریه‌ها از فضای بین دنده‌ای اول تا ششم کشیده شده بودند. براساس یافته‌های بافت‌شناسی بیشترین قسمت پارانشیم ریه کبک چوکار از برونشیول‌های درجه سوم (پارابرونشیولها) تشکیل یافته بود. پارابرونشیولها توسط سپتوم‌های با الاستیته ضعیف از یکدیگر جدا می‌شدند. یافته‌های این تحقیق می‌تواند به عنوان مرجعی استاندارد در شناسایی خصوصیات رادیولوژی و هیستوآناتومی سیستم تنفسی و تفسیر تصاویر رادیولوژی و همچنین در معاینات بالينی و امور درمانی این نوع از پرنده مورد استفاده قرار گیرد.
This study aimed to evaluate the radiological and histoanatomical structure of the respiratory system of adult chukar partridge (Alectoris chukar). In this study, 8 Chukar partridges (4 males and 4 females) with an average weight of 550 grams were used. For radiological studies radiographs with left and right lateral, dorsal-ventral, and ventral-dorsal views were prepared from the quails under study. Then the lungs and trachea were examined anatomically and topographically. Following anatomical studies, histological studies were performed. Based on the results of this study, in the abdominal-dorsal, the left and right lungs were visible on the sides of the vertebral column. In the lateral view, the lungs were located in the dorsal position and the anterior part of the coelomic cavity and were better visible. In this view, the lungs were positioned behind the heart, and due to the presence of parabronchiules, they showed the appearance of a honeycomb. The trachea was visible from the pharynx to the bifurcation of the syrinx. Macroscopic observations showed that the lungs lacked lobes and there was no pleural space. Due to the absence of the pleural membrane, the lungs were connected to the surrounding tissues through fibrous tissue. The back surface of the lungs was convex and the same as the curvature of the ribs. The visceral surface was concave and located towards the heart and liver and it was the entry point of the main right and left bronchi. The lungs were stretched from the first to the sixth intercostal space. Based on the histological findings, most of the lung parenchyma of chukar partridge (Alectoris chukar) was composed of third-degree bronchi (Parabronchi). The parabronchi were separated from each other by weakly elastic septa. The findings of this research can be used as a standard reference in identifying radiological and histoanatomy characteristics of the respiratory system and interpreting radiological images, as well as in clinical examinations and treatment of this type of bird.
