摘要
昼夜节律是有机体适应自然环境的一种表现,本文依据昼夜节律的特点,选用明期(09:00)和暗期(21:00)的两个时辰对大白鼠的血象进行测定。结果发现:红细胞两个时辰变化不显著;白细胞由09:00时的16.2±2.6×10~9/L降至21:00时的7.5±2.8×10~9/L(P<0.01);血小板由494±110×10~9/L降至243±82×10~9/L(P<0.01);血红蛋白却由70.7±26g/L上升至75.1±12.3g/L(P<0.05)。说明大白鼠的血象具有昼夜节律。
The circadian rhythm of hemogram in rat was investigated. At 09: 00 and 21: 00,experiment was made. The result showed that RBC was unchanged, WBC and platelet decreased (P<0,01),but Hb increased (P<0.05 ). The circadian rhythm seem to affect hemogram of rat.
