【摘要】 本文报道用微量中和试验测定73例急性和慢性病毒性心肌病患者血清柯萨奇B病毒中和抗体水平,并与39名正常人作比较。结果:柯萨奇B病毒中和抗体滴度≥1;64的阳性率,急性心肌病组为74.2%,慢性心肌病组为52.4%,对照组为28.2%,抗体滴度≥1;128的阳性率,急性心肌病组为54.8%,慢性肌心病组为33.3%,对照组为7.7%。本文认为血清柯萨奇B病毒中和抗体滴度≥1;128可作为病毒性心肌病病因学诊断依据之一。更多还原

【Abstract】 The antibody titre against coxsackie B virus is determined by microneutralization test in 73 cases of acute and chronic viral cardiomyopathy and in 39 normal individuals. The titres of≥1:64 in acute viral cardiomyopathy, chronicviral cardiomyopathy and normal subjects are 74.2%, 52.4% and 28.2% respectively (P<0.001 and P<0.05). The positive rates of the titres of≥1:128 are54.8%, 33.3% and 7.7% in the three groups respectively (P<0.001 and P<0.05). It is concluded that the titre of≥1:128 could be considered as a positive diagnotic criterion of coxsackie B viral cardiomyopathy.更多还原
