人,像许多种动物那样,细胞免疫和体液免疫的反应能力随年龄的增加而逐渐降低。作者采用六种不同指标:E玫瑰花、抗人T淋巴细胞抗原(HTLA)血清、“早期”(early)E玫瑰花、ECA玫瑰花、EA玫瑰花和表面免疫球蛋白(SmIg)等方法,检测了118例(男76例,女42例)健康人外周血T和B淋巴细胞亚群的数量。其中新生儿26例(13个男性,13个女性,出生后3～21天),婴儿12例(3个男性,9个女性,出生后3个月),成年人40例(20～50岁),老年人40例(75～97岁)。结果发现: 1.全血总的淋巴细胞的百分数和绝对数在新生儿和婴儿之间没有统计学差异。
People, like many kinds of animals, the cellular and humoral immune response ability decreases with age. The authors used six different measures: E rose, anti-human T lymphocyte antigen (HTLA) serum, early E rose, ECA rose, EA rose and surface immunoglobulin (SmIg) The number of T and B lymphocyte subsets in 118 healthy volunteers (76 males and 42 females) were detected. There were 26 newborns (13 males and 13 females, 3-21 days after birth), 12 infants (3 males and 9 females, 3 months after birth) and 40 adults (20-50 years old) ), 40 elderly patients (75 to 97 years old). The results showed that: 1. The percentage and absolute number of total lymphocytes in whole blood were not statistically different between newborns and infants.
