Abstract

|
|
|
Osteoporosis means a deficiency in the amount of bone tissue in the skeleton or part of the skeleton. Osteoporosis is a lesion, not a specific disease. ’’Osteoporotic’’ describes the slate of a bone or skeleton at a given time. Osteoporosis may be diagnosed subjectively by visual appraisal, or objectively by measurement of radiographs, sawn bones, or microscopic sections. This study was carried out to make clear of the influence of ovariectomy on time course of fibular osteoporosis in rats. Seven weeks after ovariectomy, osteoporosis was evident, when the size of the bone marrow cavities significantly increased and the width from the bone marrow cavity and cortex significantly decreased than normal.
