Bu çalışmada, in vivo etkide farklı kurşun konsantrasyonlarına maruz bırakılan tilapia (Oreochromis mossambicus, L.1758) balığının eritrosit morfolojisinde meydana gelen değişimler araştırılmıştır. Balıklar düşük (0,5 mg L-1), orta (2,5 mg L-1) ve yüksek (5 mg L-1) kurşun konsantrasyonlarına semi-statik olarak 14 gün boyunca maruz bırakılmıştır. Deneme sonunda orta ve yüksek doz kurşuna maruz bırakılan gruplarda kontrol grubuna göre önemli değişimler görülmüştür (p<0,05). Orta ve yüksek dozlarda kurşun eritrosit çekirdek alanı, uzunluğu ve genişliğinde kontrole göre önemli azalmaya neden olurken, sitoplazma alanı ve hücre genişliğinde kontrol grubuna göre önemli bir artma göstermiştir (p<0,05). Artan kurşun konsantrasyonlarının O. mossambicus eritrosit hücre morfolojisinde hipertrofi, anizositoz ve karyopiknozise neden olabileceği sonucuna varılmıştır.

Changes in Erythrocyte Morphology of Tilapia (Oreochromis mossambicus) Exposed to Lead

Öz

In this study, changes of erythrocyte morphology of Tilapia (Oreochromis mossambicus, L.1758) exposing to the different concentrations of lead have been investigated. Fish were exposed to low (0,5 mg L-1), medium (2,5 mg L-1) and high (5 mg L-1) lead concentrations semi-statically during 14 days. At the end of the experiment, important changes in the treatment groups exposed to medium and high lead concentrations were shown than the control group (p<0.05). Medium and high doses of lead red blood cell nucleus area, an important reduction in the length and width compared to the control, while the width of the cell cytoplasmic space and the control group showed a significant increase (p<0.05). It was concluded that increasing lead concentrations might cause hypertrophy, anisocytosis and cariopicnosis in erythrocyte cell morphology of O. mossambicus.
