Much more prolongation ofsurvival term and improvement of survival rate,as well as appearance of a great dealof lymphocytes around pulmonary metastatic nodes and less pulmonary metastaseswere also observed in murines treated with activated、tumor antigen-pulsedmacrophages contrast to those treated with IL-2 gene-transfected macrophageswithout prior pulse of tumor antigen in vitro.

肿瘤抗原冲击的IL-2基因转染巨噬细胞治疗组小鼠期存活明显延长，肺转移结节明显减少，局部病理显示，肺肿瘤周围出现大量淋巴细胞浸润，我们推测这可能是因为抗原冲击的活化巨噬细胞除了增强对肿瘤细胞直接的杀伤效应外，还对其进行处理加工，将免疫信息传递给周围的淋巴细胞，从而引起其增殖活化，并浸润肿瘤组织中。

This prospective, nonrandomized, open study took place at a private dermatology practice. A sequence of four groups, each made up of 10 to 20 office patients with DSO, were treated with pulse-dosed oral terbinafine, 250 mg per day for seven consecutive days, at intervals of two, three, and four months. Treatment was stopped when the distally advancing new nail bed and nail had completely removed the mycotic defect, or when fungistasis had failed.
