小鼠外周血白细胞计数变异很大,其正常值的报告也不一致。本实验采用北京医科大学动物部的健康成年雄性LACA小鼠12只.观察两个月,晚八点采尾血,常规计数及分类,共计10次。结果如下:白细胞计数7800～18100/mm~3。分类:中性粒占36.6～54.8％,淋巴占42.1～61.8％,单核占0～5％,嗜酸、 Mouse peripheral blood leukocyte count variation, the report of its normal value is also inconsistent. In this study, 12 healthy adult male LACA mice from Animal Department of Beijing Medical University were used.Forteted blood was collected at two months and eight at night, routine counting and classification, a total of 10 times. The results are as follows: white blood cell count 7800 ~ 18100 / mm ~ 3. Classification: Neutrophil 36.6 ~ 54.8%, lymphatic 42.1 ~ 61.8%, mononuclear 0 ~ 5%, eosinophilic,
