The result were as follows:
1. The age of admitted patients changed evidently into middle and old aged class.
2. Among these patients, 38 per cent were expected discharge from sanatorium by improvement, but 44 per cent were not.
3. The cases which were not responded to treatment and were expected discharge, were observed in 78 per cent of the group of F and G2, 3 KY3, Z type by Gakken's
