Abstract

Leishmania major, one of the causative agents of cutaneous leishmaniasis, is an obligate intracellular parasite. In this study, the toxic effect of hydrogen peroxide (H2O2) upon L maior promastigote cells was investigated. L. maior promastigote cells were propagated in medium-199 supplemented with 20 % fetal calf serum (FCS) in log phase. Toxicity of H2O2 for L. major promastigote cells was assessed with a colorimetric assay using 'MTT (4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide). Hydrogen peroxide, at concentrations equal and greater than 125 xM, demonstrated a toxic effect upon L. maior promastigote cells. After filtration of the Staphvlococcus aureus-added 10 mM Hfi2 solution, it was observed that the lethal effect upon L. major was abolished.

Özet

Kütanöz leishmaniazis etkenlerinden biri olan Leishmania major zorunlu hücre içi parazittir. Bu çalışmada hidrojen peroksit (H2O2)'in L. maior progmastigot hücreleri üzerine toksik etkisi araştırıldı. L. major progmastigot hücreleri % 20 fetal calf serum (FCS) içeren medium-199 besiyerinde logaritmik fazda üretildi. Hidrojen peroksitin L. major promastiaot hücrelerine toksik etkisi MTT (4,5-dimetiltiazol-2-yl)-2,5-difeniltetrazolium bromür) maddesi kullanılarak kolorimetrik yöntem ile değerlendirildi. Hidrojen peroksitin 125 /iM ve daha üzerindeki konsantrasyonlarında L. major promastigot hücrelerine toksik etki gösterdiği saptandı. Staphvlococcus aureus eklenen 10 mM' lık H^OJ ın fütrasyon sonrasında L. major promastigot hücreleri üzerine olan öldürücü etkinin kaybolduğu saptandı.
