With human chromosomes,as antigen,anti—human—chromosome antibodies (AhChrA)were detected specifically from SLE patients sera by the methods of immunogold—silver staining(IGSS)and immnuofluorescenee tese (IFT)。To SLE,the sensitivity and specificity of serumAhChrA was 58.1%and98.5%respeetively in IGSS,34.9%and99.5%respectively in IFT。Boththe incidence and titer of AhChrA were found to be colsely related to the pathoactivity and thedamages of some important organs or tissues,such as kidney damage,abnormal immunity andhematocytopenia.A preliminary analysis of the antigen components reacting to AhChrA was alsoperformed。
