为了研究霰粒肿组织中肿瘤坏死因子 (TNF)的表达 ,探讨霰粒肿的确切病因。采用SABC免疫组织化学 ,对 42例霰粒肿组织中肿瘤坏死因子的分布与表达进行研究。结果 :42例中 34例阳性 ,8例阴性。提示肿瘤坏死因子在霰粒肿的发生中起重要作用。
In order to study the expression of tumor necrosis factor (TNF) in chalazion tissue and to explore the exact etiology of chalazion. Using SABC immunohistochemistry, the distribution and expression of tumor necrosis factor in 42 cases of chalazion were studied. Results: Of the 42 cases, 34 were positive and 8 were negative. Tumor necrosis factor play an important role in the occurrence of chalazion.
