چکیده

مقدمه: اختلال در فرایند میلین‌سازی به دلیل مواجهه با پرفلئورواکتانوئیک اسید (Perfluorooctanoic acid یا PFOA) می‌تواند منجر به بروز اختلالات حرکتی شود. در مطالعه‌ی حاضر، اثرات مواجهه با PFOA در دوران بارداری بر تخریب بافت میلین مغز نوزاد موش صحرایی مورد بررسی قرار گرفت.روش‌ها: موش‌های بارور با نژاد Wistar به صورت تصادفی در پنج گروه شامل گروه‌های شاهد، شم (Sham) و سه گروه دریافت کننده‌ی PFOA با دزهای 1، 5 و 10 میلی‌گرم/‌کیلوگرم وزن بدن، تقسیم شدند. در پایان مطالعه، مغز موش‌های نوزاد 20 روزه خارج شد و با استفاده از رنگ‌آمیزی‌های لوکسال فست‌بلو و ایمونوهیستوشیمی مورد بررسی قرار گرفت. در نهایت، داده‌ها با استفاده از نرم‌افزار SPSS مورد واکاوی قرار گرفت.یافته‌ها: میانگین تراکم میلین در گروه دریافت کننده‌ی PFOA با دز 10 میلی‌گرم بر کیلوگرم نسبت به سایر گروه‌ها کاهش معنی‌داری داشت (050/0 > P).نتیجه‌گیری: نتایج این مطالعه نشان داد که مواجهه با PFOA در زمان حاملگی، می‌تواند منجر به اختلال در فرایند ساخت میلین شود. از این رو، پیشنهاد می‌شود در دوران بارداری از مواجهه با عوامل توکسیک نظیر PFOA اجتناب گردد.

چکیده [English]

Background: Disruption of myelination process due to exposure to perfluorooctanoic acid (PFOA) can lead to movement disorders. In the present study, the effects of exposure to PFOA during pregnancy on myelin degradation in brain of newborn rat were investigated.Methods: Fertile Wistar rats were randomly divided into five groups of control, sham, and three groups receiving PFOA at doses of 1, 5, and 10 mg/kg body weight. At the end of the study, the brains of 20-day-old neonatal rats were removed and examined using loxal fast blue and immunohistochemical staining. Finally, the data were analyzed using SPSS software. Findings: The mean myelin density in the group receiving PFOA at a dose of 10 mg/kg was significantly lower than the other groups (P < 0.050).Conclusion: The results showed that exposure to PFOA during pregnancy can lead to disruption of myelin production process; so, it is recommended to avoid exposure to toxic agents such as PFOA during pregnancy.
