Glucocorticoid is widely used in hospitals,and its mayor harm is osteoporosis.High dose of dexamethasonum was administered to rabbits for from four to eight weeks respectively.With the use of scanning electron microscope(SEM),the authors observed the bone trabecula at the proximal metaphysis of the femur in the rabbits.With the period of treatment became longer,there were manifested ations of thinning and discontinuance of the trabeculae.Apparently,these structural changes were followed by decline of the mechanical strength.
