为了解肿瘤患者的抗-A、抗-B效价同正常人是否有差异,我们对本院确诊的155例肿瘤患者进行了调查,现将结果报道如下。1 观察对象与方法1.1 对象 肿瘤组:本院确诊的肿瘤患者155例。对照组:重庆巴县地区来我院献血者183例。1.2 方法 试管法。采静脉血,用双草酸抗凝后,分离血浆,将血浆倍比稀释,每管加相对应的2％红细胞悬液1滴。1000r/min,离心1min;取出稍加振摇,仔细观察,以不显凝集的前一管作为抗体的效价。数据经t
To understand whether the anti-A and anti-B titers of cancer patients are different from those of normal people, we investigated 155 tumor patients diagnosed in this hospital. The results are reported below. 1 Observed objects and methods 1.1 Subjects Tumor group: 155 cases of cancer patients diagnosed in our hospital. Control group: 183 cases of blood donors from our hospital in Chongqing County. 1.2 Methods Test tube method. After venous blood was collected and anticoagulated with oxalic acid, the plasma was separated and the plasma was serially diluted. One drop of the corresponding 2% erythrocyte suspension was added to each tube. 1000 r / min, centrifugation 1min; remove slightly shaken, carefully observed, in order to agglutinate the former tube as antibody titer.
