作者采用 Mancini 免疫扩散法,对一组肝癌病人系统地进行了血清免疫球蛋白的测定。病人分为两组:一组为原发性肝癌25例,均经组织学证实,其中16例甲胎蛋白阳性,占64％。另一组继发性肝癌(来自肺、卵巢、乳房、骨、胃、食道、胰腺转移)28例。据作者的操作方法,免疫球蛋白的平均正常值为;IgG(免疫球蛋白 G)800～ The authors used the Mancini immunodiffusion method to systematically measure serum immunoglobulins in a group of liver cancer patients. The patients were divided into two groups: one group consisting of 25 cases of primary liver cancer, all confirmed by histology, and 16 cases of alpha-fetoprotein were positive, accounting for 64%. Another group of 28 cases of secondary liver cancer (from lung, ovary, breast, bone, stomach, esophagus, pancreas metastasis). According to the author’s method of operation, the average normal value of immunoglobulin; IgG (immunoglobulin G) 800 ~
