مقاله پژوهشی




مقدمه: بیماری مزمن کلیوی یک بیماری کاتابولیکی است، که منجربه آتروفی عضلانی می‌شود. هدف از پژوهش، مقایسه‌ی تأثیر دو نوع تمرین با شیب مثبت و شیب صفر بر بهبود آتروفی عضلانی و عملکرد کلیه موش ماده نژاد C57bl6 مبتلابه بیماری مزمن کلیوی بود.
روش‌ها: تعداد ۲۴ سر موش ماده نژاد C57bl6 دوماهه با وزن 1/26 ± ۲۵ گرم تصادفی به چهار گروه: کنترل سالم، کنترل بیمار، بیمار و تمرین هوازی با شیب صفر و بیمار و تمرین هوازی با شیب مثبت تقسیم شدند. به منظورالقای بیماری کلیوی پودر آدنین 0/2 درصد میلی‌گرم بر کیلوگرم به مدت ۴ هفته به صورت خوراک دریافت کردند. گروه‌ تمرین هشت هفته تمرین تردمیل (۵ جلسه در هفته) یک گروه با شیب ۲۰ درجه و گروه دیگر با شیب صفر درجه اجرا کردند. پس از آخرین جلسه‌ی تمرین، خون‌گیری به منظور اندازه‌گیری اوریک اسید، اوره و کراتینین به روش الایزا انجام شد. بیان ژن‌های Myod,Myogenin,Myf-5 با تکنیک qPCR-Real Time اندازه‌گیری شد. برای تجزیه ‌و تحلیل آمار از آزمون ANOVA  یک طرفه و تعقیبی Tukey در سطح معنی‌داری 0/05 ≥ P استفاده شد.
یافته‌ها: نتایج نشان داد، القای بیماری کلیوی، موجب افزایش معنی‌دار مقادیر اوره، اوریک اسید وکراتینین سرم نسبت به گروه کنترل سالم می‌شود (0/05 > P). از سویی در گروه تمرین با شیب مقادیر اوره، اوریک اسید و کراتینین سرم کاهش معنی‌دار وجود دارد (0/05 > P). میزان بیان Myod, Myogenin ,Myf-5 در گروه تمرین با شیب افزایش معنی‌دار داشت ( 0/05 > P).
نتیجه‌گیری: تمرینات با شیب، سبب کنترل آتروفی عضلانی و بهبود دهنده‌ی مقادیر اوره، اوریک اسید و کراتینین در موش مبتلا به بیماری مزمن کلیوی می‌شود و اثر تمرین با شیب نسبت به بدون شیب بهتر می‌باشد.

چکیده [English]

Background: Chronic kidney disease is a catabolic disease, which leads to muscle atrophy. The purpose of the research was to compare the effect of uphill incline and zero incline training on improving of muscle atrophy and kidney function in C57bl6 female mice suffering from chronic kidney disease(CKD).
Methods: A total of 24 two-month-old female C57b16 mice weighing 25 ± 1.26 grams, were randomly divided into four groups: healthy control, patient control, patient and aerobic exercise with zero incline, and patient and aerobic exercise with positive incline. To induce CKD, they received adenine powder at a concentration of 0.2% mg/kg orally for four weeks. The training groups performed eight weeks of treadmill training (five sessions per week) with one group exercising on a 20-degree incline and the other on a zero-degree incline. After the last training session, blood samples were collected to measure serum uric acid, urea and creatinine using the ELISA method. The expression levels of the Myod, Myogenin, Myf-5 genes were measured using real-time quantitative PCR (qPCR). For statistical analysis, a one-way ANOVA test and Tukey's post hoc test were employed, with a significance level set at P ≤ 0.05.
Findings: The results showed that induction of CKD caused a significant increase in the amount of urea, uric acid and serum creatinine compared to the healthy control group (P < 0.05). On the other hand, there is a significant decrease in the values of urea, uric acid and serum creatinine in the training group (P < 0.05). The expression levels of Myod, Myogenin and Myf-5 increased significantly in the slope training group (P < 0.05).
Conclusion: Exercises performed on an incline controlled muscle atrophy and improves urea, uric acid and creatinine levels in mice with chronic kidney disease. Furthermore, the effects of incline exercise were found to be superior to those of exercise without incline.
