近年来有报道,磷脂(?)肌醇(以下简称Pi)及其代谢产物在癌病发生过程中有重要作用。本文论证利用全血Pi指标诊断颌面部恶性肿瘤的可能性。材料和方法检查颌面部鳞癌134例。对照组是50例健康献血者。用改进的流动薄层层析法检查红细胞、血小板、淋巴细胞、血浆和全血Pi含量。用双缩脲法测 In recent years, it has been reported that phosphatidylinositol (PI) and its metabolites play an important role in the development of cancer. This article demonstrates the possibility of using the whole blood Pi index to diagnose malignant tumors in the maxillofacial region. Materials and Methods 134 cases of maxillofacial squamous cell carcinoma were examined. The control group was 50 healthy blood donors. The Pi content of red blood cells, platelets, lymphocytes, plasma, and whole blood was examined with modified flow cytometry. Biurea assay
