Abstract

The aim of this study was to determine the effects of BPA on testes development in chicken embryos. For this purpose, 310 fertile eggs of Isa Brown laying parent stock were divided into five groups as control, vehicle-control, 50, 100, and 250 µg/egg BPA. Test solutions were injected into the yolk before incubation. At the 13th, 18th and 21st days of incubation, the eggs were opened until six living male embryos were obtained from each group. Tissue samples were fixed in 10% buffered formalin (pH 7.4). After routine histological processes, tissue samples were embedded in paraffin. Six µm thickness sections were stained with the Crossmon’s trichrome method. All histological evaluation and histometrical measurements were performed on the left testes. On the 13th, 18th and 21st days of the incubation, the groups that were treated with BPA showed growth retardation in testicular tissues, fewer cell cords and poorly cellular organization. At 21 days of the incubation, there were a significant decrease in the mean diameter of the seminiferous tubule in all experimental groups compared to control groups (p

Özet

Bu çalışmanın amacı Bisfenol A (BPA)ʹnın tavuk embriyolarında testis gelişimi üzerindeki etkisini belirlemektir. Bu amaçla Isa Brown ırkı yumurtacı tavuklara ait 310 adet döllü yumurta kontrol, taşıyıcı kontrol, 50, 100, 250 µg/yumurta BPA olmak üzere 5 gruba ayrıldı. Test solüsyonları inkübasyondan önce yumurta sarısına enjekte edildi. İnkübasyonun 13. 18. ve 21. günlerinde her gruptan 6 adet canlı erkek embriyo elde edilene kadar yumurtalar açıldı. Alınan testis dokuları %10'luk tamponlu formalin (pH 7.4) solüsyonunda tespit edildi. Dokular rutin histolojik metotlarla takip edilerek parafinde bloklandı. Bloklardan alınan 6 μm kalınlığındaki kesitlere ise Crossmon'un üçlü boyama yöntemi uygulandı. Tüm histolojik ve histometrik değerlendirmeler sol testis’ler üzerinde yapıldı. İnkübasyonun 13. 18. ve 21. günlerinde BPA uygulanan gruplarda testis dokularında gelişme geriliği, az sayıda hücre kordonu ve zayıf hücresel organizasyon gözlendi. İnkübasyonun 21. gününde deney gruplarının ortalama seminifer tubul çaplarında kontrol gruplarına kıyasla belirgin düşüşler tespit edildi (p
