The analysis was performed of influence of urban and rural population on peripheral blood cell counts in 961 children aged 0 to 7 years. No relevant differences were found in peripheral blood cell counts in urban and rural children. This could be explained by a marked penetration of the urban population by the country people. The predominance of the lymphocyte count over the granulocyte count occurred first as soon as on the 5th day of life, lasted until the 66th month of life when it got reversed. The physiologic erythrocytopenia has been found as soon as in the 2nd month of life.
对961名0至7岁儿童的城乡人口对其外周血细胞计数的影响进行了分析。城乡儿童的外周血细胞计数未发现相关差异。这可以用农村人口大量涌入城市来解释。淋巴细胞计数高于粒细胞计数的情况最早在出生后第5天出现，持续到第66个月，之后情况逆转。生理性红细胞减少最早在出生后第2个月就已发现。
