The numbers of T, B, and "null" blood lymphocytes were determined in 216 normal healthy persons, whose ages ranged from 20 to 94 years. No change was found in the numbers of T or B lymphocytes with increasing age of the subjects, whereas both the total lymphocytes and the number of "null" lymphocytes decreased just significantly with age (p less than 0.05). The response of blood lymphocytes to phytohaemagglutinin in vitro was measured in 25 subjects aged 20-30 years and compared with the response in 23 subjects aged over 60 years. There was no significant difference in the response of the two groups.
对216名年龄在20至94岁之间的正常健康人测定了T、B和“无标记”血液淋巴细胞的数量。随着受试者年龄的增加，未发现T或B淋巴细胞数量有变化，而总淋巴细胞和“无标记”淋巴细胞数量均随年龄显著减少（p<0.05）。对25名年龄在20至30岁之间的受试者测定了血液淋巴细胞对植物血凝素的体外反应，并与23名年龄超过60岁的受试者的反应进行了比较。两组的反应没有显著差异。
