摘　　要：报道一种从全血中分离嗜中性白细胞的方法．人血经过葡聚糖沉降，淋巴细胞分离液梯度分离，特殊分离液的洗涤和红细胞的溶胀后，得到了嗜中性白细胞．经瑞特氏染色和台盼蓝染色证明细胞纯度与存活率均在９５％以上．以化学发光和细胞色素ｃ还原法证明了细胞的高活力与膜受体的完整性．与国外的分离方法相比较，该方法简便易行，且分离效果好，是一种高效、经济的分离方法．A modified method for seperating neutrophils from whole blood was reported. Neutrophils was obtained by dextran sedimentation, centrifuged with lymphocytes separating solution, special seperting medium washing and erythrocyte depletion. The purity and viability were proved to be both about 95% by Wright's stain and Typan blue respectively. Both the chemiluminescence method and cytochrom c reduction method proved the high activity and the integrity of the membrane receptor of the neutrophils. Compared with other method, this method is more simple and easier to handle, which suggests that it is a efficient and economic method for seperating neutrophils.
