چکیده
هدف: این پژوهش با هدف بررسی اثر ده هفته تمرین هوازی و مصرف عصاره دانه‌ی گلرنگ بر بیان ژن PIK3R1 و عملکرد کلیه پس از مصرف دگزامتازون در موش‌های صحرایی نر بالغ طراحی شد.
روش‌شناسی: تعداد 25 سر موش صحرایی نر بالغ نژاد ویستار (وزن32±371 گرم) به‌طور تصادفی به پنج گروه کنترل، دگزامتازون، دگزامتازون+گلرنگ (mg/kgbw 500، به‌صورت روزانه، توسط گاواژ)، دگزامتازون+تمرین هوازی(60 دقیقه، سرعت 28 متر/دقیقه، پنج روز در هفته، ده هفته)، دگزامتازون+گلرنگ+ تمرین هوازی تقسیم شدند. القای آسیب کلیوی با تزریق زیرپوستی دگزامتازون (mg/kgbw 8) به مدت شش روز انجام شد. تجزیه و تحلیل داده‌ها با آزمون آنالیز واریانس دو‌طرفه در سطح معناداری 05/0P≤ انجام شد.
یافته‌ها: یافته‌های بیان ژن PIK3R1 تأثیر معناداری را در گروه‌های مختلف نشان نداد. علی‌رغم تغییرات مشاهده شده در بافت‌شناسی کلیه، دگزامتازون موجب تغییرات غیرمعنادار اوره و اسیداوریک شد. نتایج حاصل از این مطالعه نشان داد که ده هفته مصرف عصاره‌ی گلرنگ موجب کاهش معنادار اوره و افزایش غیرمعنادار اسیداوریک در موش‌های مبتلا به آسیب کلیوی شد. همچنین ده هفته تمرین هوازی نیز موجب کاهش معنادار اوره و کاهش غیرمعنادار اسیداوریک در موش‌های مبتلا به آسیب کلیوی شد. علی‌رغم تغییرات معنادار اوره و غیرمعنادار اسیداوریک تمرین هوازی و عصاره‌ی گلرنگ می‌تواند موجب بهبود آسیب کلیوی شود.
نتیجه‌گیری: به نظر می‌رسد ده هفته تمرین هوازی و مصرف عصاره‌ی دانه ی گلرنگ می‌تواند موجب بهبود آسیب کلیوی شود اما مداخله گرهای این پژوهش نمی‌توانند تغییری در بیان ژن PIK3R1 ایجاد کنند.

چکیده [English]
Aim: The aim of present study is to evaluate the effects of ten weeks of aerobic exercise and consumption of safflower seed extract on PIK3R1gene expression and serum creatinine levels in male rats, after consuming Dexamethasone.
Method: 25 male Wistar rats (371± 32 gr) were randomly divided into five groups including; control, dexamethasone, dexamethasone + safflower (500 mg/kg of body weight), dexamethasone + aerobic exercise (60 minutes, speed of 28m/min, 5 days a week), dexamethasone + safflower + aerobic exercise. Kidney damage was induced by subcutaneous injection of Dexamethasone (8 gr /kg of body weight) for 6 days.
Results: Findings didn’t show a significant effect in the expression of PIK3R1 gene in different groups. Despite the observed changes in renal histology, dexamethasone caused insignificant changes in urea and uric acid. The results of this study showed that 10 weeks of consumption of safflower extract caused a significant decrease in urea and an insignificant increase in uric acid in mice with kidney damage. Also, 10 weeks of aerobic exercise significantly reduced urea, while causing an insignificant reduction in uric acid in mice with kidney damage. Despite changes in urea and uric acid, aerobic exercise and safflower extract can improve kidney damage.
Conclusion: It seems that 10 weeks of aerobic exercise and consumption of safflower seed extract can be effective in improving kidney injury but the interveners in this study could not alter the expression of the PIK3R1 gene.
