作者研究了100例重症肌无力患者和45例其他神经肌肉病病人,测定这两种病人的血清中对多核苷酸,多核苷酸—多核尿苷酸及天然和变性的DNA抗体。全部重症肌无力患者均可检测到抗乙酰胆(卤咸)受体的抗体,平均滴度为1.2×10~(-7)M。用微孔滤膜放射免疫试验法检查病人血清中的抗多核苷酸抗体,结果48％的重症肌无力病人有此抗体, The authors studied 100 patients with myasthenia gravis and 45 patients with other neuromuscular disorders and determined the serum levels of polynucleotides, polynucleotides - polynucleotides and natural and denatured DNA antibodies in both patients. Antibody to anti-acetylcholine receptor was detected in all patients with myasthenia gravis with the average titer of 1.2 × 10 ~ (-7) M. Using microporous membrane radioimmunoassay to examine anti-polynucleotide antibodies in patient serum, 48% of myasthenia gravis patients had this antibody,
