The leukocyte blood composition was studied for seven years in dogs kept outdoors. The lymphocyte count proved to be higher from May to September than from November to March. Variations in the neutrophil and monocyte count were subject to reverse regularity. Changes in the total leukocyte count failed to coincide with the seasonal periodicity.
对户外饲养的狗的白细胞血液成分进行了为期七年的研究。结果证明，淋巴细胞计数在5月至9月高于11月至3月。中性粒细胞和单核细胞计数的变化则呈现相反的规律。白细胞总数的变化与季节周期性不一致。
