Abstract

AIM: Particulate matter is an important air-pollutant and its toxicity has been reported. Diesel exhaust particles (DEP) constitute a large portion of particulate matter. Therefore, we established our study to investigate the effects of DEP on neural tissue in early stage chicken embryos. MATERIAL and METHODS: Four study groups and one control group, each of which included 24 objects were designed. Eggs were incubated for 30 hours. Solutions of DEP containing 10, 50, 100, and 200 &#956;g/0.1 ml were prepared with serum saline. At the end of thirty hours diesel exhaust particle solutions were administered under the embryonic discs. After 72nd hour of the incubation, embryos were excised and evaluated macroscopically and histopathologically. RESULTS: The difference between the embryos that were defined as poorly and well developed, was found statistically significant (p<0.05). Neural tube defects were detected in 16 of 104 embryos. Statistically significant association between the administration of DEP and development of neural tube defect was identified (p=0.037). CONCLUSION: Thus, the direct neurotoxic effects of DEP, which the whole population encounters inevitably, have been shown in the early stages of embryonic development. Further studies are needed to identify the effects of these particles in the later stages of embryonic development.

Özet

AMAÇ: Parçacık madde, önemli bir hava-kirleticidir ve toksik olduğu bildirilmiştir. Dizel egzoz parçacıkları, parçacık maddenin önemli bir kaynağıdır. Biz de dizel egzoz parçacıklarının erken dönem tavuk embriyosunda nöral doku gelişimi üzerine etkilerini araştırmak için çalışmamızı planladık. YÖNTEM ve GEREÇ: Her birinde 24 denek olan 4 çalışma ve 1 kontrol grubu planlandı. Yumurtalar 30. saate kadar inkübe edildi. Serum fizyolojik ile dizel egzoz parçacıklarından 10, 50, 100 ve 200 μg/0,1 ml olacak şekilde solüsyonlar hazırlandı. 30 saat sonunda dizel egzoz parçacığı solüsyonlarından embriyonik diskler altına injekte edildi. İnkübasyonun 72. saatinde embriyolar çıkarıldı ve makroskopik ve histopatolojik olarak değerlendirildi. BULGULAR: Embriyolar arasındaki fark istatistiksel olarak anlamlı bulundu (p<0.05). 104 embriyonun 16 adedinde nöral tüp defekti saptandı. Tüm gruplarda dizel parçacığı verilmesiyle nöral tüp defekti gelişmesi arasında istatistiksel anlamlı ilişki bulundu (p=0.037). SONUÇ: Böylece, kaçınılmaz şekilde tüm toplumun maruz kaldığı dizel egzoz parçacıklarının embriyonel gelişimin erken dönemlerinde doğrudan nörotoksik etkileri gösterildi. Bu parçacıkların embriyolojik gelişimin sonraki dönemlerindeki etkilerinin ortaya konabilmesi için ileri çalışmalara ihtiyaç vardır.
