关于嗜酸性粒细胞(Eos)特异性颗粒的化学成份虽有较多的了解,但其确切作用仍不太清楚。同中性粒细胞相比,Eos的吞噬作用较弱,而且在化脓性感染部位常难以见到。然而,当血液中Eos数超过1.5×10~9/l时,在下列疾病中均可见到组织的Eos浸润,如寄生虫病,免疫缺陷儿童的感染性疾病,内因性哮喘,某些脉管炎性和肉芽肿性疾病,结缔组织病(如结节性多动脉炎和Eos肋膜炎),皮肤病(如天疱疮样病,多种药疹),恶性肿瘤(如支气管癌,何杰金病,T-细胞白血病)。在排除了这些主要疾病后,仍有一些Eos持续
Although the chemical composition of eosinophilic granulocytes (Eos) -specific particles is well understood, its exact role remains unclear. Compared with neutrophils, Eos phagocytosis is weak, and often difficult to see in the purulent infection site. However, when the number of EOS in the blood exceeds 1.5 × 10 ~ 9 / l, Eos infiltration of the tissue can be seen in the following diseases such as parasitic diseases, infectious diseases in immunocompromised children, endogenous asthma, certain vessels Inflammatory and granulomatous diseases, connective tissue diseases (such as polyarteritis nodosum and Eos pleurisy), dermatoses (such as pemphigus, multiple drug eruptions), malignancies (such as bronchial carcinoma, Hodgkin’s disease , T-cell leukemia). After excluding these major diseases, there are still some Eos continued
