我科从1970年6月开始试用血清铝反应辅助诊断消化道肿瘤。现将初步结果介绍如下:方法及病例选择方法:试剂:称三氯化铝(AlCl_3·6H_2O)50毫克溶于100毫升蒸馏水中。操作:取0.5毫升血清注入内径为10毫米的小试管内,加试剂0.3毫升混合均匀。垂直放沸水浴中1分钟(准确计时)。取出后静置30秒后观察结果。 Our department from June 1970 began trial serum aluminum reaction to assist in the diagnosis of gastrointestinal tumors. Now the preliminary results are introduced as follows: Methods and Case Selection Method: Reagents: 50 mg of aluminum trichloride (AlCl 3 · 6H 2 O) was dissolved in 100 ml of distilled water. Operation: Take 0.5 ml of serum into a small test tube with an inner diameter of 10 mm, add reagent 0.3 ml and mix well. Vertical boiling water bath for 1 minute (accurate timing).
