عنوان انگلیسی New Physical Approaches combined with nanoparticles in Leishmania major Treatment
چکیده انگلیسی مقاله Introduction: Cutaneous leishmaniasis is a mutual parasitic disease, which is endemic in some countries of the world. The use of common drugs has been restricted because of confirmed side effects and drug resistance. There are still serious challenges in the treatment of CL. Developing new therapeutic methods for leishmaniasis, besides obtaining a prompt treatment response that prevents lesions' progression and scarring, is a significant success in the treatment of the disease. Novel approaches such as nanotechnology have been applied as a therapeutic modality. This study aimed at evaluating the influence of three physical approaches combined with nanoparticles on promastigotes, amastigotes, and lesion-induced parasites. Materials and Methods: Leishmania promastigotes were treated with gold nanoparticles combined with different duration of the microwave with 2450 MHz frequency. So, the promastigotes treated with electroporation and ultraviolet irradiation in presence of silver and titanium dioxide nanoparticles respectively. Leishmania amastigotes were preserved by GNP and SNP with different conditions exposure of Microwave irradiation and electroporation. Ultraviolet irradiation in presence of silver nanoparticles used to reduce the size of lesion-induced parasites. Results: Promastigotes survival rate induced a significant decline in different conditions of all three approaches in the presence of nanoparticles in comparison to similar samples without there. The least survival of amastigotes was also recorded in the groups containing nanoparticles received the microwave and electroporation. In addition, the findings on parasite burden and size of lesions showed a significant difference between the treatment groups with SNPs and UV irradiation and control group. Conclusion: The finding emphasized to the utility of new approaches by nanotechnology could be useful for the treatment of cutaneous disease such as leishmaniasis. For validation of this statement need to more research and some studies have been planned for this aim.
