| Abstract: | The methods to find hereditary muscular dystrophy mice (dy-mice) were described. One was to observe whether or not mice dragged their hind limbs immediately after they were dropped onto a table following their suspension by their tails. The other was to observe dragging their hind limbs immediately after they were restored to a normal position from a supine one. This limbs-dragging induced by these methods were characteristic of dy-mice. Among 437 mice checked by these methods, 76 showed the drag during 14-23 days after birth (18.3 days on the average) and later they were confirmed to be dy-mice without exception. Therefore, it was concluded that these methods were useful for the accurate diagnosis of dy-mice at an early stage. |
