1879年Ehrlich发现血液中有一种胞浆含嗜碱性染色颗粒的白细胞,称为嗜碱性粒细胞(Basophilic leukocyte, BL)。BL占血液白细胞的1%。由于分离精制的困难,对其功能和其在机体防御机理上的重要性认识较晚。至今仍有一些问题尚待阐明。
Ehrlich discovered in 1879 that there was a cytoplasmic basophilic leukocyte called basophilic leukocyte (BL) in the blood. BL accounted for 1% of blood leukocytes. Due to the difficulty of separation and purification, its function and its importance in the body defense mechanism awareness late. There are still some problems to be clarified yet.
