【摘要】 本文采用单向琼脂扩散试验（SRTD）血循环免疫复合物测定法（CiC）及淋巴细胞转化试验（LTT）对50例复发性口腔溃疡患者及50例正常人进行了系列免疫指标测定.实验结果表明患病组TgG、TgA、IgM、C₃及LTR明显降低,而CIC含量显著升高,与对照组相比（P<0.01）,有非常显著的差异。由此表明复发性口腔溃疡可能为自身免疫性疾病。更多还原

【Abstract】 In this paper, we have determined series immune index of 50 patients with Aphthae ulcer （RAU） and 50 normal persons, using SRID, CIC and LTT. LTR_?Ig and C₃ of patients with RAU remarkably decreased,CIC increased obviously. Compared with the controlled group, there was remarkable difference（P<0.01）. The results show that RAU may be a self-immunity disease.更多还原
