マウスの遺伝的白内障について

Hereditary cataract in mice

　国立予防衛生研究所で飼育されているマウスに，1958年1月偶々眼球に異常をみとめるマウスが見出され，この異常は後述の如く白内障であることがたしかめられた。

　今回はそのあらわれ方，遺伝的性質について検討を行つた結果を報告する。

An occurrence of abnormality in the eye was found among animals belonging to a line which had been raised at the mouse colony in the National Institute of Health. The eye abnormality was observed through the course from eye opening to the completion of the change. It was proved as well ophthalmologically as histopathologically that the abnor-mality must be congenital cataract. Genetical studies revealed that the trait was trans-mitted recessively by a simple factor. It was suggested to give a mark (ca) to the factor.
