title: [A comparison of chromosome fragile sites in elderly and young people].
abstract: In this comparative study, the authors investigated the chromosome aberrations and expression of fragile sites in the lymphocytes which were collected from 45 elderly people and 29 young people and were cultured with FUDR for 24 hours. The results showed that the aberration rate was 24.75% for elderly people, but 4.22% for young people (P < 0.01): that the expression of fragile sites was 45.94% for elderly peoples, but 23.02% for young people (P < 0.01): and that the relation of aberrations with fragile sites was 79.98% for elderly people, and 92% for young people. These findings suggest that chromosome aberration is in close association with fragile site.
