增殖细胞核抗原（ProliferatingcellnucLarantisen，PCNA）是一种36kd的酸性核蛋白，其表达状况与癌细胞增殖活性有关。本文用免疫组化染色方法研究PCNA在食管鳞癌中的表达，并探讨其临床意义。1材料和方法我院1987年12月～1989年12月手术切除食管鳞癌存档蜡块SO例。男42例，女
Proliferating cell nuclear growth factor (PCNA) is a 36 kd acidic nuclear protein whose expression status is related to the proliferation activity of cancer cells. In this paper, the expression of PCNA in esophageal squamous cell carcinoma was studied by immunohistochemical staining and its clinical significance was discussed. 1Materials and Methods In our hospital from December 1987 to December 1989, surgical resection of esophageal squamous cell carcinoma paraffin blocks was performed. 42 males and females
