Effects of malathion in fetal kidney tissues in pregnant rats: teratogenic effects ınduced by different doses

Bu çalışmanın amacı gebe ratlara düşük dozlarda subakut uygulanan Malathion (ML)’un fetüs böbrek dokusu üzerine teratojenik etkisini araştırmaktır. Toplam 28 Sprague-Dawley gebe rat randomize olarak her grupta 7 adet gebe rat olacak şekilde 4 gruba ayrıldı. ML’un dozuna bağlı olarak, gruplar; kontrol, ML 2.5 (2.5 mg/kg/gün dozunda oral yoldan (p.o) ML uygulandı), ML 5 (5 mg/kg/gün, p.o) ve ML 10 (10 mg/kg/gün, p.o) olmak üzere 4 gruba ayrıldı. ML uygulamsı erkekler ve dişilerin aynı ortama konulmasından itibaren başladı (çiftleşmeden itibaren). Günlük ML uygulamasına doğuma kadar devam edildi. ML’un, dozuna paralel bir şekilde gebe ratlarda böbrek dokusu ve serum enzimleri (asetilkolinesteraz (AChE), lipaz, amilaz) üzerine toksik etkiler oluşturduğu, ayrıca yavru rat böbreklerinde ise ML’un dozuna bağlı olmayarak, tüm dozlarda teratojenik etkiye neden olduğu belirlendi. Histopatolojik veriler biyokimyasal verileri doğruladı. ML’un düşük dozlarının bile hem anne hem de yavru böbrekleri üzerine toksik ve teratojenik böbrek hasarına neden olduğu sonucuna varıldı.

Gebe ratlara farklı dozlarda uygulanan malathionun fetüs böbrek dokusu üzerine teratojenik etkileri

The aim of this study was to investigate the teratogenic effects of Malathion (ML) induced by different doses on fetal kidney tissues in pregnant rats. A total of 28 Sprague-Dawley pregnant rats were randomly divided into 4 groups of 7 rats each. Depending on ML dose, four groups were formed, including (I) control, (II) ML 2.5 (ML 2.5 mg/kg/day, orally), (III) ML 5 (5 mg/kg/day, orally), and (IV) ML 10 (10 mg/kg/day, orally). ML application started when the male and female were put together (when mating started). Daily ML application was continued until birth. It was determined that in parallel with dose of ML, ML resulted in toxic effects on serum enzymes (acetyl-cholinesterase (AChE), amylase and lipase) and kidney tissues of pregnant rats, and also -regardless of ML dose in fetal kidneys- it led to teratogenic effects in all the doses. Biochemical data wasconfirmed by histopathologic data. We concluded that ML leads to kidney damage in both pregnant and fetal rats as a result of its teratogenic and toxic effects.
