RESUMO
Nanotechnology and its byproducts are used increasingly considering its global nanotechnology market size and many applications in the health field. The aim of the present study was to investigate the effect of aerobic and anaerobic exercises on cellular uptake of nanoparticles in body tissues. Fusarium oxysporum was used to synthesize biological AgNPs in silver nitrate solution and UV-vis spectrophotometer; XRD and TEM were used to confirm production of nanoparticles. Moreover, 45 male Wistar rats were purchased and randomly divided into 9 equal groups including healthy control groups, aerobic preparation, anaerobic preparation, biological AgNPs, chemical AgNPs, biological AgNPs+aerobic preparation, biological AgNPs+anaerobic preparation, chemical AgNPs+ aerobic preparation, chemical AgNPs+anaerobic preparation. In order to induce aerobic and anaerobic preparation and to create tissue adaptations, male rats completed two types of aerobic and anaerobic protocols three sessions per week for 10 weeks. At the end of the study, sampling was done for histopathology study. The size and shape of AgNPs was 20-30 nm and spherical to polygonal, respectively. The results showed that anaerobic exercise was significantly effective in weight loss. The chemical nanoparticle group led to more intensive tissue degradation in all variables and there were no significant tissue changes in the aerobic, anaerobic, the biological nanoparticles + aerobic and anaerobic groups. It seems that biological AgNPs are more effective than chemical AgNPs on body tissues and chemical AgNPs lead to more tissue damage in most variables. RESEARCH HIGHLIGHTS: There were severe degradative histological effects in the chemical AgNPs groups compare biological AgNPs groups, in terms of most variables.
