草酸是曲霉菌尤其是黑色曲霉菌的酵解产物,在曲霉菌侵犯的机体组织中常有草酸沉积。有人报道肺草酸盐沉积症与肺曲霉菌病有关。因此,作者回顾性研究了免疫受损患者支气管肺泡灌洗(bronchoalveo-lar lavage,BAL)液中的草酸含量,探讨其对肺曲霉菌病的诊断价值。实验对象分为两组:Ⅰ组14例,为 BAL 直接镜检或培养、或尸检证实的肺曲霉菌病患者;Ⅱ组37例,
Oxalic acid is the product of the fermentation of Aspergillus, especially Aspergillus niger, and often oxalic acid deposits in the tissues of the body invading Aspergillus. It has been reported that pulmonary oxalate deposition is associated with pulmonary aspergillosis. Therefore, the authors retrospectively studied the oxalic acid content in bronchoalveolar lavage (BAL) fluid of immunocompromised patients and explored its diagnostic value for pulmonary aspergillosis. The subjects were divided into two groups: 14 cases in group I were patients with pulmonary aspergillosis confirmed by direct microscopy or culture of BAL or confirmed by autopsy; group (n = 37)
