Unlike neutrophils and eosinophils, basophils are non-phagocytic.

和中性粒细胞和嗜酸性粒细胞不同的是，嗜碱性粒细胞并不具备吞噬功能。

Now, in comparison to neutrophils, eosinophils and basophils are far less common.

比起中性粒细胞，嗜酸性粒细胞、嗜碱性粒细胞要不常见得多。

Eosinophils stain pink with the dye eosin - which is where they get their name.

嗜酸性粒细胞用伊红Eosin染色呈粉红色，也就是它英文名Eosinophil的来源。

This inflammation is caused by infiltration of immune cells, like neutrophils and eosinophils, which then cause inflammation.

这种炎症是由于免疫细胞渗入导致的，比如中性粒细胞和嗜酸性粒细胞，从而造成炎症。

IL-5, on the other hand, activates eosinophils which promote an immune response by releasing more cytokines and leukotrienes.

另一方面，IL-5激活嗜酸性粒细胞，通过释放更多的细胞因子和白三烯来促进免疫反应。

The mucus may also contain Charcot-Leyden crystals which are shaped like needles and are formed by the breakdown of eosinophils.

黏液中也可能含有一些针状的Charcot-Leyden晶体，由嗜酸性粒细胞分解形成。

That wouldn't give you an elevated eosinophil count.

脉管炎不会导致嗜酸性粒细胞增加。

Loffler syndrome, where eosinophils accumulate in the lung tissue, can also affect the heart tissue, called Loeffler endocarditis or sometimes loeffler endomyocarditis.

Loffler综合征：嗜酸性粒细胞聚集在肺组织中，也可以累及心脏组织，这种情况叫做Loeffler心内膜炎，有时也叫Loeffler心内膜肌炎。

Early symptoms include oliguria and eosinophiluria, which is eosinophils in the urine, but also general symptoms like a fever and a rash.

早期症状包括少尿和嗜酸性尿，即尿液中存在嗜酸性粒细胞，但也有发烧和皮疹等一般症状。

In this case, eosinophils accumulate in the endocardial layer of the heart tissue, causing inflammation and endocardial fibrosis, making it stiffer and again less compliant.

在这类病例中，嗜酸性粒细胞聚集在心脏组织的心内膜层，导致炎症和心内膜纤维化，让其更加僵硬、顺应性更差。
