X chromatin analysis of 30 aged and 30 control women failed to confirm X chromosome loss as responsible for the increase in incidence of hypodiploid cells observed with increasing age in women. No evidence was found to support a previously suggested relationship between X chromosome loss and the loss of mental function (senility) as measured by psychological tests.
对30名老年女性和30名对照女性进行的X染色质分析未能证实X染色体丢失是导致女性随着年龄增长观察到的亚二倍体细胞发生率增加的原因。没有证据支持先前提出的X染色体丢失与通过心理测试测量的心理功能丧失（衰老）之间的关系。
