The studies of serum from a case with C9 (the ninth component of complement) deficiency are described. A 29-year-old woman in good health was found to have low serum complement levels (CH50). C9 of her serum was undetectable by the hemolytic assay and by the immunochemical analysis but all other components were normal. It was demonstrated that low CH50 of her serum was due to the hemolysis of the sensitized sheep erythrocytes (EA) by the complement components from C1 to C8.
本文描述了对一名C9（补体第九成分）缺乏症患者血清的研究。一名29岁身体健康的女性被发现血清补体水平（CH50）较低。通过溶血试验和免疫化学分析，均未检测到其血清中的C9，但所有其他成分均正常。结果表明，其血清中CH50较低是由于补体成分C1至C8对致敏绵羊红细胞（EA）的溶血作用所致。
