Effects of Combination Treatment with Pulsed Electromagnetic Fields and Electroacupuncture on Ovariectomy-induced Osteoporosis in Rats
摘要
Abstract
Objective To explore whether combination treatment with pulsed electromagnetic fields ( PEMFs) and electroacupuncture ( EA) have additive benefits on bone mineral density( BMD) and biomechanical properties in OVX rats. Methods Fifty 3-month old female Sprague-Dawley rats were assigned to one of five groups:sham-operated control ( Sham) ,ovariectomy ( OVX) ,ovariectomy with PEMFs treatment ( PEMFs) ,ovariectomy with EA treatment ( EA) ,and o-variectomy with PEMFs﹢EA treatment ( PEMFs﹢EA) . After 12-week treatments,bone mineral density,histomorphometric parameters,and bone biomechanical properties were examined. Results PEMFs,EA and combination treatment signifi-cantly increased BMD of the femur (P<0. 01,P<0. 05) compared to OVX group. There was no significant difference in the femur BMD among the five groups(P>0. 05). PEMFs,EA and combination treatment significantly increased BMD of L5 vertebral body (P<0. 01) compared to OVX group. What’s more,combination treatment with PEMFs and EA was more ef-fective than PEMFs or EA alone for improving BMD in L5 vertebral body(P<0. 05). The biomechanical three-point ben-ding experiment showed that PEMFs and combination treatment significantly increased maximum load in the left femur com-pared to OVX group (P<0. 05). There was no significant difference in maximum load of the left femur among the five groups(P>0. 05). The compression test showed that PEMFs,EA and combination treatment significantly increased maxi-mum load (P<0. 01) and energy to failure (P<0. 01) in L5 vertebral body compared to OVX group. What’s more,combi-nation treatment was more effective than PEMFs or EA alone for improving maximum load (P<0. 05,P<0. 01) and energy to failure (P<0. 01) in L5 vertebral body. Conclusions Combination treatment with PEMFs and EA have additive ben-efits on BMD and bone biomechanical properties in the lumbar vertebral body.关键词
