In this study, juvenile common carp (Cyprinus carpio) were subjected to sublethal concentrations of the synthetic pyrethroids cypermethrin (2 µg/L) and cyphenothrin (5 µg/L) for 75 days. The toxic effects of these substances were analyzed pathomorphologically by conducting necropsies on 7 fish on days 15, 30, 45, 60, and 75. In addition, histopathological examination of the gonads was performed by exposing to 17β-estradiol (E2) (25 µg/L) as a positive control group to assess the endocrine disrupting effects of cypermethrin and cyphenothrin. Hyperemia, telangiectasia, epithelial lifting, and branchitis were observed in the gills of the fish from both treatment groups, and hemorrhage in the kidneys and hyperemia in the brain were also detected. Only 1 fish from each of the cypermethrin and E2 groups was observed to have degeneration of the testicles and edema of the ovary. One fish from the cyphenothrin group had degeneration of the testicles and another had oophoritis of the ovary. Based on the hyperemia and telangiectasia observed in the gills, it was concluded that both cypermethrin and cyphenothrin may lead to shortness of breath in these fish. However, only minor lesions were detected in the gonads; thus, there was no evidence that these synthetic pyrethroids affect the endocrine system

Cypermethrin ve cyphenothrinin sazan balıklarına toksik etkisinin patomorfolojik yöndendeğerlendirilmesi
Öz
Bu çalışmada, sentetik piretroitlerden olan cypermethrin ve cyphenothrinin belirlenen sublethal dozları (2 µg/L ve 5 µg/L) juvenil sazan (Cyprinus carpio) balıklarına 75 gün süreyle uygulandı. Her gruptan yedişer balığın nekropsileri 15, 30, 45, 60 ve 75. günlerde yapılarak toksik etkileri patomorfolojik yönden değerlendirildi. Cypermethrin ve cyphenothrinin endokrin sisteme olan etkilerini değerlendirmek amacıyla pozitif kontrol olarak 17β-estradiol (E2) (25 µg/L) verilerek gonadlar da histopatolojik yönden incelendi. Cypermethrin ve cyphenothrin grubuna ait balıkların solungaçlarında hiperemi, telangiektazi, epitelde ayrılma ve branşitis ile karşılaşıldı. Böbreklerde kanama ve beyinde hiperemi dikkati çekti. Gonadlarda ise cypermethrin ve E2 grubuna ait sadece birer balıkta testiste dejenerasyon ve birer balıkta ovaryumda ödem ile karşılaşıldı. Cyphenothrin grubuna ait bir balıkta ovaryumda ooforitis, bir balıkta ise testiste dejenerasyon görüldü. Solungaçlarda oluşan hiperemi ve telangiektazi bulguları birlikte değerlendirildiğinde; cypermethrin ve cyphenothrinin balıklarda solunum yetmezliğine yol açabilecekleri sonucuna varıldı. Bu çalışmada, gonadlarda az sayıda lezyon görülmesi nedeniyle sentetik piretroitlerin endokrin sisteme olan etkileri saptanmadı
