Introduction: Free radicals increase with age and disease, so the aim of this study was to investigate the effect of exercise and vitamin D on the expression of alkaline phosphatase and osteocalcin genes in bone tissue of rats poisoned with hydrogen peroxide.
Methods: In this experimental trial, 36 adult male Wistar rats were randomized into six groups of six rats, 1) control; 2) hydrogen peroxide; 3) hydrogen peroxide + vitamin D; 4) hydrogen peroxide + exercise; 5) hydrogen peroxide + exercise and vitamin D and 6) Sham. For eight weeks, groups 2, 3, 4, and 5 were given daily dose of 1 mmol/kg hydrogen peroxide on even days, groups 3 and 5 received 0.5 mg / kg of Vitamin-D daily, and sham group received only vitamin D solvent intraperitoneally. Groups 4 and 5 performed aerobic exercise 3 day/week. Osteocalcin and alkaline phosphatase gene expression were measured by PCR and were analyzed using independent t-test, two-way analysis of variance and Boferroni’s post hoc test with SPSS 16 (p≤0.05).
Results: The interactive effect of exercise and vitamin D on increasing alkaline phosphatase and osteocalcin was significant. (p≤0.05); exercise increased alkaline phosphatase and osteocalcin (p ≤ 0.05); vitamin D was also associated with increased alkaline phosphatase and osteocalcin (p=0.0001). The greatest effect on increasing osteocalcin and alkaline phosphatase showed in groups 5 and 3, respectively (p=0.001).
Conclusion: Exercise and vitamin D had a positive effect on bone tissue, so that even the systemic effect of hydrogen peroxide could not change the results of this constructive effect.
