Abstract: (1050 Views) |
Background & objectives: Menopause and especially acute menopause due to surgery is associated with many complications in women. The aim of this study was to determine the effects of genistein and regular swimming exercise (alone/or in combination) on pain through a possible mechanism of inflammation and oxidative stress in ovariectomized rats.
Methods: In this study, rats were divided into six groups, including: control, sham, ovariectomy (OVX), ovariectomized with eight weeks of swimming exercise training (OVX.E), ovariectomized with eight weeks of genistein administration (OVX.G), and ovariectomized with eight weeks of combined treatment (OVX.G.E). The effects of genistein and/or exercise were evaluated by examining the pain intensity with tail-flick and formalin tests. The serum levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), total antioxidant capacity (TAC), total oxidant status (TOS), and malondialdehyde (MDA) were also evaluated by ELISA and spectrophotometer.
Results: In the OVX group compared to the control group, tail-flick and formalin tests showed an increase in pain response. Also, a significant increase in the serum levels of IL-1β, TNF-α, MDA, TOS and a decrease in TAC was observed in the OVX group, however, in the OVX.E, OVX.G and especially OVX.E.G groups, pro-inflammatory cytokines and oxidative stress as well as pain responses showed a significant decrease compared to the OVX group.
Conclusion: A combination of genistein and regular swimming exercise was synergistically more effective in reducing acute and chronic pain than using them alone in the postmenopausal period.
