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.
12주령 랫트의 양측 난소를 적출한 후, 난소적출이 골다공증 형성에 미치는 영향을 이해하고자 본 연구를 시행하였던 바 아래와 같은 결과를 얻었다. 난소적출 후 매주 골소실이 일어나기 시작하였으며 5주부터 시작하여 7주에서는 정상대조군에 비하여 골소실의 증가가 두드러지게 나타났다. 이상의 결과를 종합해보면 랫트의 난소를 적출하여 여성호르몬의 결점을 유발하면 난소적출 후 5주부터 시작하여 7주에는 골다공증이 발생되었다.
