Abstract
Frequency of the fluorescent Y-chromatin bodies in the white blood elements of aged men was found to be significantly lower than that of young men (aged: N=35, mean frequency 68,78%; young: N=47, mean frequency 75,96%). This finding indicates that in the progressed age, the Y-chromosome tends to get lost from the cell, probably as a consequence of generalized functional im pairment of aged cell.
摘要
研究发现，老年男性白细胞中荧光Y染色体小体的频率显著低于年轻男性（老年组：N = 35，平均频率68.78%；年轻组：N = 47，平均频率75.96%）。这一发现表明，在老年阶段，Y染色体可能由于衰老细胞普遍的功能受损而倾向于从细胞中丢失。
