胸腺瘤系一种上皮细胞肿瘤,瘤内常伴有不同程度的淋巴细胞浸润。准确测定胸腺瘤组织中浸润淋巴细胞的数量及不同成熟期细胞亚群是评定胸腺瘤功能的客观依据。而传统的组织学方法难以达到上述目的,故应用能够衡量淋巴细胞成熟标志的OKT 系列单抗检测了16例胸腺瘤患者。按测定的淋巴细胞亚群可将胸腺瘤分为三型:(1)胸腺淋巴细胞型:本型有12例病人,淋巴细胞亚群特征为,OKT_6~+细胞占52～95%,OKT_3 Thymoma is an epithelial tumor, the tumor often accompanied by varying degrees of lymphocyte infiltration. Accurate determination of the number of infiltrating lymphocytes in thymoma tissue and the different subpopulations of mature cells is an objective basis for assessing the function of thymoma. Traditional histological methods are difficult to achieve these goals, so OKT series of monoclonal antibodies that measure lymphocyte maturation markers were used to detect 16 patients with thymoma. According to the measured lymphocyte subsets, thymoma can be divided into three types: (1) Thymus lymphocyte type: There are 12 patients in this type. The characteristics of lymphocyte subsets are as follows: OKT_6 ~ + cells account for 52 ~ 95%, OKT_3
