对正常人31名,腮腺肿瘤患者44名(良性25名,恶性19名)的混合唾液和腮腺液中 IgA,IgG 含量进行了测定,结果表明:腮腺恶性肿瘤患者第一、二段腮腺液中 IgG 浓度比正常组、良性腮腺肿瘤组明显升高。腮腺良、恶性肿瘤腮腺液中 IgA 浓度无显著差别。影响混合唾液中 IgA 和 IgG 的含量因素多,对诊断和鉴别肿瘤性质意义不大。
The contents of IgA and IgG in mixed saliva and parotid gland fluid of 31 normal people and 44 salivary gland cancer patients (25 benign and 19 malignant) were measured. The results showed that the parotid gland cancer patients had first and second parotid gland fluids. The IgG concentration was significantly higher than that of the normal group and the benign salivary gland tumor group. There was no significant difference in IgA concentration in parotid gland fluid between benign and malignant salivary glands. There are many factors affecting the content of IgA and IgG in the mixed saliva, which is of little significance for the diagnosis and differentiation of tumor properties.
