我们采用末端脱氧核苷酸转移酶（ TDT）介导的 d-UTP－生物素缺口末端标记（ TUNEL）技术检测凋亡细胞，同时应用抗增殖细胞核抗原（ PCNA）免疫组化法检测增殖细胞，研究各种良恶性皮肤淋巴增生性疾病中细胞凋亡指数、增殖指数以及两者之间的比率，探讨它们在皮肤淋巴增生性疾
We detected the apoptotic cells by terminal deoxynucleotidyl transferase (TDT) -mediated d-UTP-biotin nick end labeling (TUNEL), and detected proliferating cells by immunohistochemistry with anti-proliferating cell nuclear antigen (PCNA) To study the apoptosis index, proliferation index and the ratio between them in various benign and malignant cutaneous lymphoepithelial diseases,
