2010

Abstract

Introduction: With the onset of menopause, reduced estrogen levels and decreased physical activity created serious problems with resultant osteoporosis and fractures. Recent moves away from hormone replacement therapy suggested exercise, as the simplest and cheapest strategy to treat and prevent osteoporosis. Aim of the Work: The present study aimed to focus (from the histological point of view )on the efficacy of exercise in the amelioration of osteoporotic bone loss in ovariectomized rats with special reference to bone mineral density and bone histomorphometry. Materials and Methods: Forty adult female albino rats were used and divided into four groups. Group I (control group) which were further subdivided into 2 equal subgroups, Ia: received no intervention. Subgroup Ib included nonovariectomized rats experiencing daily exercise training program. Group II (overiectomized rats) which were further subdivided into 2 equal subgroups. Subgroup IIa: were ovariectomized on day 1 of the ...
