Abstract

AIm: Nitrogen Mustard (NM) is an alkylating agent that damages cellular nuclear DNA after penetrating tissue. This results in cytostatic, mutagenic and cytotoxic effects. We used biochemical analyses to investigate the effect of NM gas administered through the dermal and respiratory routes, on the brain cortex of rats and also tried to show whether the antioxidant Proanthocyanidin (PC) could decrease this effect. Ma terIal and Methods: A total of 30 rats were randomized into three groups: Group I: Control group, Group II: NM group, and Group III: NM + PC group. The rats were sacrificed 3 days after NM gas exposure. A segment of the cortical tissue was prepared for biochemical analyses. Results: Biochemical analyses of cortical neural tissue regarding the Enzymatic Antioxidant Defense against NM were performed. The results of these analyses implied that PC was effective for healing of cortical neural tissue. ConclusIon: These findings imply that structural changes induced by mustard gas can be prevented and restored by proanthocyanidin treatment.

Özet

AMAÇ: Nitrogen Mustard (NM) dokuya penetre olduktan sonra hücrede mutagenik ve sitotoksik etkilere neden olan alkilleyici bir ajandır. Cilt ve respiratuvar yoldan uygulanan NM gazının, rat beyin dokusunda enzimatik antioksidan savunma mekanizmaları üzerine etkisi ve proantosiyanidin’in (PC) tedavi değerinin araştırılması amaçlandı. YÖNTEM ve GEREÇLER: Toplam 30 rat üç gruba randomize edildi: Grup I: Kontrol grubu, Grup II: NM grubu, Grup III: NM+PC grubu. Ratlar NM gazı uygulamasından 3 gün sonra sakrifiye edildiler. Biyokimyasal analizler için kortikal bir doku segmenti hazırlandı. BULGULAR: NM için kortikal nöral dokunun Enzimatik Antioksidan Defans mekanizmaları ile ilgili biyokimyasal analizler uygulandı. Analiz sonuçları kortikal nöral dokunun iyileşmesi üzerine PC’nin etkili olduğunu ima etmektedir. SONUÇ: Bu bulgular mustard gazının indüklediği yapısal değişikliklerin proantosiyanidin tedavisi ile önlenebildiği ve onarılabildiğini ima etmektedir.
