作者对14例慢淋患者和12例正常人淋巴细胞表面球蛋白(SIg)和免疫球蛋白分泌能力进行了研究。用免疫荧光染色法测定SIgM阳性细胞,用放射免疫分析技术进行SIgM定量,从而计算出SIgM密度。12例正常人中,SIgM阳性细胞平均为8% The authors studied the lymphocyte surface globulin (SIg) and immunoglobulin secretory capacity in 14 patients with chronic lymphocytic leukemia and 12 healthy individuals. SIgM positive cells were determined by immunofluorescence staining and SIgM quantification was performed by radioimmunoassay to calculate SIgM density. In 12 cases of normal people, the average number of SIgM positive cells was 8%
