Generalized amyloidosis in a partridge (Alectoris chukar)

Bu çalışmada bir keklikte generalize amiloidozis olgusu tanımlandı. Çalışmanın materyalini Ankara Üniversitesi Veteriner Fakültesi Patoloji Anabilim Dalı’na nekropsi amacıyla getirilen 1 yaşlı, erkek, kınalı keklik (Alectoris chukar) oluşturdu. Nekropside karaciğer, dalak ve böbrekler oldukça şişkindi. Solgun renkte olan bu organların kolayca parçalandığı dikkati çekti. Histopatolojik incelemede; dalakta (kapsülada, beyaz pulpanın ince retiküler ağı boyunca, beyaz pulpa ve trabeküllerdeki damar duvarlarında); karaciğerde (disse aralıklarında, ve damar duvarlarında); böbreklerde (tubulusların bazal membranında ve damar duvarlarında); duodenum ve jejenumda (lamina propria’da, damar duvarlarında, tunika muskularis’te); kaslı ve bezli midede (lamina propria ve damar duvarlarında); pankreasta (damar duvarlarında); kalpte (miyofibrillerde); akciğerlerde (parabronşlarda ve damar duvarlarında); testislerde (tubulus bazal membranında ve damar duvarında) homojen, amorf pembe renkte birikimler gözlendi. Yapılan Congo-red özel boyasıyla bu birikimlerin kırmızımsı portakal renginde boyandığı, polarize ışık mikroskobu altında ise yeşil yansıma verdiği gözlendi. Yapılan immunohistokimyasal incelemede amiloid maddesi amiloid A(AA) proteinine karşı pozitif reaksiyon verdi. Bu veriler ışığında anılan birikimlerin kanatlı hayvanlar arasında özellikle su kuşlarında rastlanan, ancak diğer kanatlılarda nadir görülen amiloid birikimi (AA amiloid) olduğu saptandı.

Bir keklikte (kınalı keklik) generalize amiloidozis

This study describes a case of generalised amyloidosis in a rock partridge (Alectoris chukar). The case material was a 1 year-old male rock partridge submitted to the Department of Pathology, Faculty of Veterinary Medicine, University of Ankara for necropsy. In necropsy, the liver, spleen and kidneys were swollen, pale and fragil. Histopathologic examinations revealed pinkish amorph accumulation in spleen (on capsule, along reticular of white pulp, in the wall of blood vessel, white pulp, and trabeculae), liver (in the dysse spaces and on blood vessels’ walls), kidneys (on tubule basal membranes and blood vessels’ walls), proventriculus, gizzard (on lamina propria and blood vessels’ walls), small intestines (on lamina propria, tunica muscularis, blood vessels’ walls), pancreas (on blood vessels’ walls), heart (on blood vessels’ walls), lungs (on bronches and blood vessels’ walls) and testes (on basal membranes of tubulus and blood vessels’ walls). After staining Congo red, accumulations appeared in orange and in green under polarised light microscope. Immunohistochemically, amyloid substance stained positively against amyloid A protein. These accumulations were considered as amyloidosis, which is rare in exotic birds, but common in waterfowls..
