چکیده
مقدمه

علی‌‌رغم مزایای متعدد، اثرات سمی و مضر نانوساختارها به یکی از دغدغه‌‌های اصلی‌‌ محققان تبدیل شده است. هدف مطالعه حاضر بررسی اثرات نانوذرات طلا بر هورمون‌‌های LH، FSH، و تستوسترون در موش‌‌های سوری نر نژاد NMRI می‌‌باشد.

مواد و روش‌‌ها

ابتدا۳۰ سر موش سوری نر نژاد NMRI به طور تصادفی به سه گروه ده تایی کنترل و گروه‌‌های تجربی شامل موش‌‌های دریافت‌‌کننده دوز ppm ۵۰ و ppm ۱۰۰ تقسیم شدند. نانوذرات طلا به مدت ۷ روز بصورت درون‌‌ صفاقی به موش‌‌ها تزریق شد. پس از اتمام این دوره، حیوانات توسط کتامین و زایلین بیهوش و خون‌‌گیری از قلب آنها انجام شد. در مرحله بعد، حیوانات تشریح و بافت بیضه از بدن آنها خارج شد و جهت انجام مراحل بافت‌‌شناسی آماده گردید. تحلیل داده‌‌ها با استفاده از نرم‌‌افزار SPSS v/۲۱ و در سطح معنی‌‌داری آماری ۰/۰۵ انجام شد.

یافته‌‌ها

نتایج حاکی از افزایش معنی‌‌دار غلظت‌‌ هورمون‌‌های LH و FSH و کاهش معنی‌‌دار هورمون تستوسترون در گروه‌‌های تجربی نسبت به گروه کنترل بود.

نتیجه‌‌گیری

با توجه به یافته‌‌ها می‌‌توان نتیجه گرفت نانوذرات طلا میزان هورمون ‌‌های LH و FSH و تستوسترون را در موش‌‌های سوری نر تغییر داده و می‌‌توانند باعث تداخل سیستم متابولیسمی شوند.

Introduction

Nanoparticles manufactured using nanotechnology, have always been a concern because of their toxic and harmful effects, despite having numerous benefits. In this study, the effect of gold nanoparticles on LH and FSH hormones as well as testosterone was investigated in males NMRI.

Materials and Methods

30 male NMRI were classified randomly into 3 groups of 10 including control and experimental groups where the mouse received 50ppm and 100ppm of nanoparticles. Then, gold nanoparticles were injected for 7 days using intraperitoneal injection and after the seven-day period, animals were anesthetized using ketamine and xylazine and blood samples are taken from heart. Then, they were dissected and testicle tissue was extracted to be prepared to perform histological studies.

Results

In this study, significant differences was observed in concentration of LH and FSH hormones (increased concentration) in taken doses and significant changes were observed in testosterone hormone (decrease) in doses of 100 and 50 ppm that could be because of the inhibiting effect of gold nanoparticles on the performance of testosterone producing cells. Statistical calculations were performed using the statistical software version SPSS v.21.

Conclusion

Results of this study showed that gold nanoparticles change the amount of LH and FSH hormones as well as testosterone in male Syrian mouse and this will result in interference with metabolism system.
