摘要
作者报道了16例经手术证实的脑包虫病,手术前用皮内试验(ID)、间接血凝试验(IHA)和对流免疫电泳试验(CIEP)三项试验方法检查结果,三项试验的阳性率分别为56.2％、46.1％和15.4％,其阳性率远远低于人体其它各部位包虫病。其主要原因与中枢神经系统的解剖学和免疫学特性有关,可能是血脑屏障阻止了脑组织中棘球蚴的代谢产物进入全身免疫系统。但在临床应用上,免疫学试验检查还是有助于流行区内脑囊性病灶的鉴别诊断。
16 patients with cerebral hydatid disease proved by operation were examined with ID, IHA, CIEP test. Positive rate of ID, IHA, CIEP test is 56.2％, 46.1％, 15.4％ respectively, which is evidently lower than that in the other parts of the body. We considered that it may be due to the characters of the anatomy and immunology of brain. The hematoencephalic barrier may prevent the product of the metabolite of hydatid cysts from entering into the immunologic system of the whole body. However, the immunologic tests can help the differential diagnosis on other cystic form disease in brain in epidemic district.
