Gebe Ratlara uygulanan Akrilamid ve E Vitaminin Plasenta Dokusu Üzerine Olası Etkilerinin Araştırılması

Gebelik boyunca akrilamid (AA) ve koruyucu olarak E vitamini (E vit) uygulanan ratların plasenta dokularında meydana gelen değişimlerin incelenmesi amaçlanmıştır. Vajinal smear ile gebelikleri doğrulanan 30 rat; Kontrol, Mısır yağı, E vitamini, Akrilamid, E vitamini + Akrilamid: grupları olmak üzere rastgele seçilerek 5 farklı gruba ayrıldı. Gebeliğin 20. gününde gebe ratlar dekapite edildi. Plasenta dokularında; malondialdehid (MDA), redükte glutatyon (GSH), total antioksidan kapasite (TAS), total oksidan kapasite (TOS) ve ksantin oksidaz (XO) düzeyleri ölçüldü. Gebe ratların plasenta dokusunda: gebelik boyunca uygulanan akrilamidin; diğer tüm gruplarla kıyaslandığında MDA, TOS, XO seviyelerini istatistiki olarak anlamlı ölçüde arttırdığı, GSH ve TAS seviyesini ise azalttığı, E vitamini uygulanan grupta ise, diğer tüm gruplara kıyasla GSH, TAS seviyelerini istatistiki olarak anlamlı ölçüde arttığını ve TOS ile XO seviyelerini ise kontrol grubu seviyelerine düşürdüğü tespit edildi. Ağız yoluyla gebe ratlara verilen AA, plasenta dokusunda MDA, XO ve TOS seviyelerini arttırarak antioksidan/oksidan dengeyi oksidanlar lehine değiştirdiği ve oksidatif strese neden olduğu, E vitamini uygulamasının ise antioksidan/oksidan dengeyi normal sınırlara getirerek oksidatif stres kaynaklı toksikasyonları önlediği görülmektedir.

Research on Possible Effects of Acrylamide and Vitamin E Administered to Pregnant Rats on Placenta Tissue

Investigate the changes that occur in the placenta tissues of pregnant rats that were administered acrylamide (AA) and vitamin E as a protective agent during pregnancy. Thirty rats that were proven positive for pregnancy with vaginal smear test were randomly distributed into control, corn oil, vitamin E, acrylamide and vitamin E + acrylamide groups. Pregnant rats were decapitated on the 20th day of the experiment. Malondialdehyde (MDA), reduced glutathione (GSH), total antioxidant capacity (TAS), total oxidant capacity (TOS) and Xanthine oxidase (XO) levels were measured in placenta tissues. It was determined that acrylamide application during pregnancy statistically significantly increased MDA, TOS and XO levels and reduced GSH and TAS levels in the placenta tissue of pregnant rats when compared to all other groups, and GAS and TAS levels statistically significantly increased in vitamin E administered group when compared to all other groups and TOS and XO levels were decreased to control group levels. It was observed that orally administered AA changed the antioxidant / oxidant equilibrium favoring the oxidants by increasing MDA, XO and TOS levels in pregnant rats and caused oxidative stress, while vitamin E administration returned the antioxidant / oxidant equilibrium back to normal levels, preventing oxidative stress induced toxicity.
