چکیده

مقدمه: بهبود آسیب اعصاب محیطی یکی از چالش های مهم از نظر کلینیکی می‌باشد. استفاده از روش های نوین مثل نانو داروها و ترکیبات طبیعی به دلیل اثرات موثر و عوارض جانبی کمتر می تواند گزینه مناسبی باشد. در این مطالعه اثرات سینرژیستی نانوذرات سریم اکسید و اوژنول در بازیابی عصب سیاتیک در مدل موش صحرایی بررسی شد. مواد و روش: بیست و هشت موش صحرایی نر به وزن 300-250 گرم به چهار گروه تقسیم شدند ((n=7. به گروه کنترل و مدل سیاتیک سالین ( ml0.5) به صورت داخل صفاقی تزریق شد. همچنین دو گروه مدل سیاتیک به ترتیب ( mg/kg50 اوژنول و mg/kg20 نانوذرات سریم اکسید) یا ( mg/kg100 اوژنول و mg/kg20 نانوذرات سریم اکسید) را به صورت داخل صفاقی دریافت کردند. سپس تست-های رفتاری حسی و حرکتی انجام شدند. بافت عضله خارج شد. در نهایت تغییرات بافت وزن عضله بررسی شد. نتایج: تزریق داخل صفاقی اوژنول همراه با نانوذرات سریم اکسید باعث افزایش سرعت بازیابی عملکرد نورون‌های حسی و حرکتی نسبت به گروه مدل سیاتیک شد. همچنین در گروه دریافت کننده اوژنول و نانوذرات سریم اکسید میزان آتروفی عضلات کمتر بود. بهبود بافت عصبی در گروه با دوز بالا معنی دار بود. نتیجه گیری کلی: با توجه به نتایج حاصل که نشان داد اوژنول و نانوذرات سریم اکسید باعث سرعت بهبود بافت عصبی می‌شود. بنابرین از پتانسیل نوروپروتکتیو آنها می توان برای درمان بیماری های مربوط به آسیب اعصاب محیطی استفاده کرد.

چکیده [English]

Introduction: Improvement of peripheral nerve damage is one of the most important challenges clinically. Using new methods such as nano drugs and natural compounds can be a suitable option due to their effective effects and less side effects. In this study, the synergistic effects of eugenol and cerium oxide nanoparticles was investigated on sciatic nerve recovery in a rat model. Method and material: In this study, twenty-eight male rats weighing 250-300 g were divided into four groups (n=7). The control group and sciatica model injected saline (0.5ml, IP). Two groups model sciatic received intraperitoneally (50 mg/kg eugenol and 20 mg/kg cerium oxide nanoparticles) or (100 mg/kg eugenol and 20 mg/kg cerium oxide nanoparticles). Then sensory and motor behavioral tests performed. The muscle tissue removed. Finally, changes in muscle weight investigated. Results: Intraperitoneal injection of eugenol plus cerium oxide nanoparticles increased the recovery speed of sensory and motor neurons compared to the sciatica model group. Also, in the group receiving eugenol plus cerium oxide the amount of muscle atrophy was lower. The improvement of nerve tissue was significant in the high-dose group. Conclusion: The results showed that eugenol/cerium oxide accelerates the regeneration of nerve tissue. Therefore, its neuroprotective potential can be used to treat diseases related to peripheral nerve damage.
