Civa-2-klorüre maruz kalmış aynalı sazan (Cyprinus carpio L., 1758) balıklarının karaciğer ve böbrek ince yapılarında gözlenen sitopatolojik değişmeler

Çalışmada 0.5ppm $HgCl_2$ dozuna 25 ve 50 gün süre ile maraz kalmış sazan balıklarının karaciğer ve böbrek dokulannda meydana gelen sitopatolojik değişmeler araştırılmıştır. Kontrol ve deneme gruplarına ait balıkların karaciğer ve böbrek numuneleri transmission elektron mikroskobunda incelenmiştir: Böbrek kesitlerinde nekrotik alanların görülmesi, civanın böbrek üzerine olan etkisinin karaciğere oranla daha fazla olduğu sonucunu doğurmuştur. Karaciğer dokusunda ilerlemiş nekroz yoktur. Ancak az miktarda elektronca yoğun madde çökelmelerinin meydana gelmesi ve lizozomal yapılarda artış izlenmesi ile civanın karaciğer hücrelerinde birikim yaparak etkili olduğu sonucuna varılmıştır. Zaman periyoduna bağlı olarak her iki organda da farklı bir dejenerasyon görülmediği gibi, uzun sürede dokularda rejenerasyon da tespit edilmemiştir.

Cyptopathological changes of mercury on the fine structures of liver and kidney of carps (Cyprinus carpio L., 1758)

Degenerative canges of mercury on the fine structures of liver and kidney of carps are described. Fish samples were exposed to the 0.5ppm doses of $HgCl_2$ for 25 days and 50 days periods. Than, the sections of liver and kidney of both test and control groups were examined by transmission electron microscope. It was observed that kidney had been degenerated much more than liver by mercury exposition. The kidney's degeneration was generally as necrotic areas on the tissues, however they were as electro-dense material and increasing of lysosomes on the cells of the liver. Cytopathologiçal deformations of liver and kidney were similar more or less on both tests groups of 25 and 50 days periods and any regeneration was not detected on the samples of 50 days-period.
