In the present study the variations in the leukocyte and erythrocyte counts were investigated in the peripheral blood within the light and darkness periods during the postnatal development of rats. The animals were kept under an artificial illumination regime (12 hours light, 12 hours darkness), and examined at the ages of 7, 14, 21, 28, 35 and 45 days, and in maturity (56 days). Erythrocyte counts exhibited no light-dark rhythm. The circadian rhythm of leukocyte counts developed in male and female laboratory rats in the fourth week of age.
在本研究中，对大鼠出生后发育过程中明暗周期外周血中的白细胞和红细胞计数变化进行了研究。将动物置于人工光照制度（12小时光照，12小时黑暗）下，并在7、14、21、28、35和45日龄以及成年期（56日龄）进行检查。红细胞计数未表现出明暗节律。雄性和雌性实验大鼠在4周龄时白细胞计数出现昼夜节律。
