近年来无脑儿较多,传染病学调查发现与巨大细胞病毒及柯萨奇B_4、B_5病毒的联合感染有关,因而产生本症的新学说。一般讲先天性胎儿畸形不外三种因子,即环境因子、遗传因子与促畸形因子。无脑儿与病毒感染可能关系很大,但这方面研究报道很少。作者观察10例无脑儿,并连同其双亲均做红细胞凝集试验、补体结合试验,发现巨大细胞病毒、柯萨奇B_4及B_5病毒的抗体效价明显增高,提示以上病
In recent years no brain more children, infectious disease investigation found that with the cytomegalovirus and Coxsackie B_4, B_5 virus co-infection, resulting in a new doctrine of this disease. In general, no more than three kinds of congenital fetal malformations, namely, environmental factors, genetic factors and pro-malformation factor. No brain children and viral infection may be a great relationship, but little research reports in this area. The authors observed 10 cases of brainless children, and together with their parents are done hemagglutination test, complement fixation test and found that the cytomegalovirus, coxsackievirus B_4 and B_5 virus antibody titers significantly increased, suggesting that the above diseases
