It is important to know the circadian rhythms of immune cells when we study the effects of exercise on immune system. The purpose of this study to investigate about the circadian rhythms of whiteblood cell and neutrophil phagocytic function in men. Seven men volunteered for this study. The blood samples were collected at 7:30, 12:00, 16:00, 20:00 and next day 8:00 (n-8:00). Counts of totasl White blood cell (WBC), neutrophils lymphocytes, monocytes and the defferental white blood count were measured. At 20:00, the number of total WBC were significancy higher than at 7:30(p<0.01), 16:00(p<0.05), n-8:00(p<0.05). Neutrophils were significantly higher at 20:00(p<0.01),16:00(p<0.05), 12:00(p<0.01) and it increased at 7:30 than 12:00. Neuriphil phagocytic index was significantly higher at 12:00 than 7:30, 16:00 and n-8:00. Neutrophil phagocytic index was significantly lower at 7:30 than 12:00 and 20:00. These dates suggested that there are circadian rhythms of the number of total WBC and neutrophil
