Total lymphocyte counts and the number of SmIg positive and E-rosetting cells in the blood of 103 healthy Brazilian children between birth and eight years and fifty-one healthy adults were compared. A high number of total lymphocytes were observed during the first year of life and decreased thereafter to reach adult values by the age of seven years. The proportion of SmIg positive cells was high in the newborn, further increased during the second trimester and remained unchanged up to the end of the first year of life. Thereafter they gradually decreased reaching adult levels by the age of three years. The percentage of E-rosetting cells was low in the newborn and young children and increased after the second year of life to reach adult levels by the age of seven years. The absolute number of both lymphocyte subpopulations changes with approximately the same pattern as the total lymphocyte counts.
对103名出生至8岁的健康巴西儿童及51名健康成年人血液中的淋巴细胞总数、Smlg阳性细胞数量和E-玫瑰花结形成细胞数量进行了比较。出生后第一年观察到大量的淋巴细胞总数，此后减少，到7岁时达到成人水平。Smlg阳性细胞比例在新生儿中较高，在孕中期进一步增加，并在生命的第一年末保持不变。此后它们逐渐减少，到3岁时达到成人水平。E-玫瑰花结形成细胞的百分比在新生儿和幼儿中较低，在生命的第二年之后增加，到7岁时达到成人水平。两个淋巴细胞亚群的绝对数量变化模式与淋巴细胞总数大致相同。
