【摘要】 作者对正常健康人73名、颅内良性肿瘤40例、恶性胶质瘤30例及脑转移瘤13例的血清TSA进行测定。结果显示：所有颅内肿瘤患者组血清TSA水平均显著高于正常对照组，其中，脑转移瘤组最高，恶性胶质瘤组次之，良性肿瘤组居第三位。所以，测定血清TSA水平对CT或MRL显示的颅内肿瘤的性质判定具有辅助诊断价值。更多还原

【Abstract】 Total sialic acid was determined in the serum in 73 normal controls,40 patients with intracranial benign tUmor, 30 patients with malignant glioma, and 13 patients with metastatic brain tumor. The resultsshowed that the level of m in the serum of those of intracranial tumours is remarkably higher than thatof noed control occupies first place, that group. of all the intracranial tumour patients, those of intracranial metastasis had the highest level of m in their serum, those of malignant glloma had the intermediatelevel of TSA in the serum, while those with benign tumor had the lowest level of m in their serum.Therefore the determination of TSA level in the serum contributes much to the judgement of the nature ofintracranial tumor by CT or MRI.更多还原
