Because of their oddly shaped nuclei, granulocytes are sometimes called polymorphonuclear leucocytes (PMN).

由于它们形状奇特的细胞核，粒细胞有时被称为多形核白细胞（PMN）。

Bacterial growth and death of alveolar macrophages produce powerful chemotactic factors that cause a large influx of polymorphonuclear leukocytes and monocytes from the peripheral blood.

军团菌的增长及肺泡巨噬细胞的死亡产生了强大的趋化因子，造成大量多形核白细胞和单核细胞从外周血涌入。

If we look at a bigger sample, like say a decilitre, then around 70% of those will be lymphocytes, 30% monocytes, and just a few polymorphonuclear cells -- PMNs -- like neutrophils.

如果我们看一个更大的样本，比如一分升；那么70％左右是淋巴细胞、30％的是单核细胞及一些多形核细胞（PMNs），比如中性粒细胞。
