| چکیده انگلیسی مقاله |
Abstract Background: Although pentavalent antimony compounds are used as antileishmanial drugs but they are associated with limitations and several adverse complications. Therefore, always effort to find a new and effective treatment is desired. In this study, the effect of ZnO nanoparticles with mean particle size of 20 nanometers (nm) on Leishmania major promastigotes and amastigotes was evaluated. Methods : Viability percentage of promastigotes after adding different concentrations of ZnO nanoparticles (30, 60, 90 and 120 µg/ml) to the parasite culture was evaluated by MTT assay. In the flow cytometry study, Annexin V-FITC Apoptosis detection Kit was used to study the induced apoptosis and necrotic effects. Result : IC50 after 24 hours of incubation was 37.8 µg/ml. ZnO nanoparticles exert cytotoxic effects on promastigotes of L. major through the induction of apoptosis. A concentration of 120 µg/ml of ZnO nanoparticles induced 93.76% apoptosis in L. major after 72 hours. Conclusion : ZnO NPs can induce apoptosis in L. major by dose and time-depended manner in vitro condition.
