Kadmiyuma Maruz Bırakılan Lymnaea stagnalis’in Ovotestis Dokularındaki Histolojik Değişiklikler

Öz

Bu çalışmada tatlı su salyangozu Lymnaea stagnalis, kadmiyumun sublethal konsantrasyonlarına (7.92 µg/L-1, 15.85 µg/L-1, 31.7 µg/L-1 and 63.4 µg/L-1) maruz bırakıldı. Deneyde 7, 14, 21 ve 28 günlük periyotlar sonunda L. stagnalis ovotestisleri alınarak histolojik preparatları hazırlandı. Kadmiyumun farklı konsantrasyonlarında ovotestislerde meydana gelen histopatolojik değişiklikler ışık mikroskobunda incelendi. Kadmiyum uygulaması sonucunda; ovotestislerde, oosit çevrelerinde vakuolleşme, spermatozoon sayısında azalma, spermatozoon ve yumurta hücrelerinde dejenerasyon, asinus hücrelerinde dejeneratif nekroz gibi değişiklikler gözlendi. Ovotestislerde lezyonların şiddeti artan kadmiyum konsantrasyonuna ve kadmiyuma maruz kalma süresine bağlı olarak paralel artış gösterdi.
