摘　　要：免疫印迹和盐裂皮肤间接免疫荧光检测 ５例大疱性系统红斑狼疮（ＢＳＬＥ）血清，对照为 ５例获得性大疤性表皮松解症（ＥＢＡ）、２０例类天疱疮（ＢＰ）、２０例ＳＬＥ和１０例正常人血清。结果表明，３例（３／５）ＢＳＬＥ血清结合盐裂皮肤真皮侧和真皮提取物中２９０ ０００抗原，其中２例ＢＳＬＥ血清也结合表皮提取物中 １６５ ０００抗原，结果与 ＥＢＡ和部分ＢＰ血清相同。ＳＬＥ血清未结合 ２９０ ０００和 １６５ ０００抗原。提示ＢＳＬＥ血清中存在ＥＢＡ和ＢＰ抗体，推测ＥＢＡ和ＢＰ抗原可能是ＢＳＬＥ的皮肤基底膜带相关抗原。Using immunoblotting analysis and salt-split skin indirect immunofluorescence, we studied sera from 5 patients with bullous systemic lupus erythematosus (BSLE) and 55 control subjects,including 20 cases of SLE, 20 cases of bullous pemphigoid (BP),5 cases of epidermolysis bullosa acquisita (EBA) and 10 normal volunteers. The results showed that the sera from 3 of 5 BSLE patients combined with dermal side of saltsplit skin and 290 000 antigen of dermal extracts in human skin. Sera from 2 BSLE patients which reacted with 290 000 antigen also combined with 165 000 antigen of epidermal extracts. Sera from SLE patients did not combined with both 290 000 and 165 000 antigens. The results suggest that there are EBA antibody and BP antibody in BSLE. We consider that EBA antigen and BP antigen may be the related antigens of skin basement membrane zone in BSLE.
