本文对肺心病血清中免疫球蛋白及补体含量变化进行研究表明,100例肺心病IgG、IgM、IgA含量范围略高于正常人,但与健康人相比,无显著性差异而补体C3含量变化较大,明显低于正常人,与健康成人相比,均有极显著性差异,说明肺心病病人补体C3有一部分被破坏,致使肺心病患者含量减低。 In this paper, the study of serum immunoglobulin and complement levels in patients with cor pulmonale showed that the content of IgG, IgM and IgA in 100 cases of pulmonary heart disease was slightly higher than that in normal people, but there was no significant difference between the two groups Larger, significantly lower than normal, compared with healthy adults, there is a very significant difference, indicating that patients with cor pulmonale, complement C3 partially destroyed, resulting in decreased levels of patients with pulmonary heart disease.
