由中国医学科学院血研所培育的615近交系小鼠已较广泛地应用于肿瘤学,免疫学等生物医学的实验研究,因而有必要对其正常生理数值进行系统的研究。鉴于615小鼠的胸腺、牌和肝指数以及外周血象正常生理数值尚未见公开报道。所以,我们在1979—1981年曾先后对三批共110只正常615小鼠进行了有关这方面的观察。现将结果整理如下 The 615 inbred mice cultivated by the Institute of Blood Research, Chinese Academy of Medical Sciences have been widely used in experimental studies of oncology, immunology and other biomedical sciences. Therefore, it is necessary to systematically study the normal physiological values. In view of the fact that the thymus gland, brand and liver index of 615 mice and the normal physiological values ​​of peripheral blood have not been publicly reported. Therefore, we conducted observations on three aspects of a total of 110 normal 615 mice in 1979-81. The results are now collated as follows
