摘要
本文报告采用F-8836单管一步法对200例9至70岁的正常健康人和260例经临床、病理证实的各类癌肿病人进行血清唾液酸(SA)测定的情况。结果显示:健康人组血清唾液酸平均吸光度为0.154±0.018 A(以大于0.19 A为阳性阈值),阳性率为8.5％(17/200);恶性肿瘤组平均吸光度为0.252±0.052 A,阳性率为83.9％(218/260)。两组间呈显著性差异(P<0.001),具有统计学意义。健康人组、恶性肿瘤组的各年龄组间无显著性差异(P>0.05)。本方法操作简单(一步完成),快速,灵敏准确,对肿瘤的早期诊断及预后判断有广泛实用价值。
F-8836 one-rube and one step method was used to measure the salivary acid level in 200 normal persons (age 9～7O) and 260 patients with various mailgnant tumours confiemed clinically and pathologically. The results showed that the mean transmittance of serum, salivary acid of health and patients groups were 0. 154±0. 018 A and 0. 252±0. 052 A (normal limit<0. 19 A) respectively and the positive rates were 8.5％ (17/200) and 83.9％ (218/260) respectively. There was significant difference (P<0.001 between two groups and no difference (P>0.05) in each age group of two groups. This method is simple, rapid accurate and can be used extensively in early diagnosis and prognosis evaluation of tumours.
