Abstract
著者는 姙娠 8日이 되는 白鼠에다 X線을 照射하고 이로부터 出生된 後 4週 乃至 5週된
白鼠의 下顎骨 發育相을 檢索한 바에서 다음과 같은 結果를 얻을 수 있었다.
1. 100∼200 rads 照射한 白鼠에서는 不規則한 骨樑이 觀察되나 構造的要素의 變化所見은
觀察하기 어려웠으나 萎縮된 核을 가진 纖維芽細胞 및 骨芽細胞를 볼 수 있었다.
2. 一般的으로 X 線 照射量이 增加함에 따라 破骨細胞의 數的인 增加現象이 觀察되고 있
었다.
3. 300 rads 照射된 白鼠에서는 固有齒槽骨을 이루는 骨樑이 不規則하고 骨髓腔은 一般的
으로 넓어지는 傾向이 있었다.
The author studied on the side effects of x-ray irradiation to the developing mandible
of the gestation and period of grow the stage rats,
For experimental observation, 100 rads, 200 rads, and 300 rads of x-ray were
irradiated in regular order at the lower abdomen of the 8th day gestated rats.
5 weeks after conception, their offspring were sacrificed and their mandibles were
extracted with intact form.
All the extracted mandible were examined for their developing modes histological
findings.
The results were as followed
1) In 100-200 rads irradiated rats offsprings, their mandibles were not revealed any
morphological changes except of the irregular pattern of trabeculatum.
In accompany with this findings, most of all the fibroblasts and osteoclasts had their
nucleus with shrunken and eccetric position,
2) In according to the increasing x-ray irradiation, marked advent of osteoclast and
cortical bone resorption were observed.
3) In 300 rads irradiated rats offsprings, there irregular pattern of trabeculae and
windening of bone morrow cavity in their alveolar proper.
