作者利用白细胞粘附抑制(LAI)试验的改良法对60名有胃肠症状的住院病人(其中最后确诊为直肠或结肠腺癌的11例;胃腺癌6例;胰腺腺癌3例)进行试验,以测定他们对结肠腺癌、胃腺癌和胰腺腺癌提取物的特异性免疫反应能力。试验方法的改进包括:单核性细胞的初步纯化;电子细胞计数器的应用以及用玻璃管代替血球计算盘作为白细胞粘附的固体表 The authors used a modification of the Leukocyte Adhesion Inhibition (LAI) test to test 60 hospitalized patients with gastrointestinal symptoms (11 of them were finally diagnosed with rectal or colon adenocarcinoma; 6 cases of gastric adenocarcinoma; 3 cases of pancreatic adenocarcinoma). To determine their specific immune response to colon adenocarcinoma, gastric adenocarcinoma and pancreatic adenocarcinoma extracts. Improvements in test methods include: preliminary purification of mononuclear cells; application of electronic cell counters and replacement of hemocytometer plates with glass tubes as solid tables for leukocyte adhesion
