EXPERIMENTAL AND CLINICAL STUDY ON PNEUMOCYSTOSIS Ⅳ USE OF A 4D7 MONOCLONAL ANTIBODY TO DETECT PNEUMOCYSTIS CARINII BY IMMUNOPEROXIDASE STAINING

摘要: 用4D7单抗-免疫组织化学方法检查31例经病原学确诊的卡氏肺孢子虫肺炎病人肺组织切片及12例高危病人合并肺部感染的痰标本。结果显示,前者31例均呈阳性,阳性率100%(31/31);后者12例中1例阳性。与银染色法及亚甲胺蓝染色法比较表明,在3种方法的阳性率之间无显著性差异。而以单抗法更为清晰,易于判断。

Abstract: This paper reports on the diagnostic utility of the 4D7 monoclonal antibody (McAb) and immunohistochemical (IHC) staining to detect P.carinii. Specimens of 30 pathological sections of lung tissues and 1 smear of aspirated bronchial material from confirmed cases,and 12 sputum smears from high risk patients with pneumonia were examined by immunohistochemical method using the 4D7 McAb.The results showed that both the sensitivity and specificity of the 4D7 McAb IHC staining were 100% (31/31).A comparison between immunohistochemical staining with GMS and TBO staining was made,no difference in sensitivity was found.However,the IHC method gave a clear back ground that is useful for definite diagnosis.
