YABAN VE EVCİL ÖRDEKLERDE PREEN BEZİ ÜZERİNDE HİSTOMORFOLOJİK VE HİSTOKİMYASAL ÇALIŞMALARI

Abstract

Bu araştırma, yaban ve evcil ördeklerin preen bezlerinin histomorfolojik ve histokimyasal yönden incelenerek aralarındaki farklılıkları ortaya koymak amacıyla yapıldı. Çalışmada beşer adet erişkin erkek yaban ve evcil Pekin ördeğinin preen bezi materyal olarak kullanıldı. Her iki türde bezin merkezi bir akıtıcı kanala açılan tubullerden oluştuğu, yaban ördeğinde parenşim/stroma oranının parenşim lehine evcil ördektekinden daha büyük olduğu belirlendi. Yaban ve evcil ördekte glikojen bölgesindeki tubuller arası bağdoku alanlarında lenfosit infiltrasyonlarına rastlandı. Yaban ördeğinde ayrıca kapsül ve glikojen bölgesindeki tubuller arasındaki bağdokuda Herbst cisimciklerinin bulunduğu gözlendi. ANAE aktivitesinin iki türün glikojen bölgesinde aynı, yağ bölgesinde farklı olduğu; asit fosfatazın ise sadece yaban ördeğinin glikojen bölgesinde yoğun olarak bulunduğu saptandı. Her iki türde bezin yağ bölgesindeki tubul epitelinin tüm katmanlarının nötral yağları içerdiği, sudanofilik yağların yaban ördeğinde yağ bölgesindeki tubul epitelinin tüm katmanlarında, evcil ördekte ise süperfisiyel hücrelerle hemen bunların altında bulunan intermediyer hücrelerde bulunduğu tespit edildi

Histomorphological and Histochemical Studies on Preen Gland of the wild and Domestic Duck

Abstract

The aim of this study is to investigate the differences of preen gland by histomorphologically and histochemically in the wild and domestic duck. Preen glands of five mature, male wild ducks and Pekin ducks were used as materials in the investigation. It was determined in the both species that gland was composed of tubules that opened a central duct and proportion of parenchyma/stroma was in favour of parenchyma in wild duck which was more high than domestic duck. In the wild and domestic ducks were found of lymphocytic infiltration in the intertubuler intersititium of glikogen zone. Also it was observed in the wild duck that capsule and intertubuler intersititium of glycogen zone were included Herbst corpuscle. It was determined that in the both species, periyodic acid-schiff and αnaphtyl acetate esterase reactivities were the same in the glycogen zone but different in the sebaceous zone; whereas, reactivity of acid phosphatase was found to be strong in the glycogen zone in the preen gland of wild duck only. It was determined in the both species that epithelial layers of tubules in the sebaceous zone were included neutral lipids totally. Sudanophilic lipids were found in the epithelial layers of tubules totally in the sebaceous zone of the wild duck whereas the superficial cells and intermediate cells, nearly located beneath of the superficial cells in the domestic duck
