我们应用免疫组织化学方法,分别用 NSE 及五种中间丝蛋白抗体对25例髓母细胞瘤进行染色,通过观察各种蛋白在细胞中的表达对肿瘤的分化潜能进行分析。(一)材料及方法:从近二年病例中随机抽取25例髓母细胞瘤,其中典型髓母细胞瘤22例,促纤维增生型髓母细胞瘤3例,肿瘤原发于小脑蚓部21例,小脑半球4例。男性18例,女性7例,儿童17例,成人8 We used immunohistochemical staining of NSE and five intermediate silk fibroin antibodies in 25 cases of medulloblastoma, respectively, by observing the expression of various proteins in the cell differentiation potential analysis of the tumor. (A) Materials and Methods: 25 cases of medulloblastoma were randomly selected from the past two years, including 22 cases of typical medulloblastoma, 3 cases of fibroblastic proliferative medulloblastoma, 21 cases of primary tumor in the cerebellar vermis 21 Cases, 4 cases of cerebellar hemispheres. 18 males, 7 females, 17 children and 8 adults
