研究了ＯＫ-432与ＩＬ-2抑制Ｃ57ＢＬ/6小鼠Ｌｅｗｉｓ肺癌(ＬＬＣ)生长及增殖细胞核抗原(ＰＣＮＡ)的表达。选用40只Ｃ57ＢＬ/6荷瘤ＬＬＣ小鼠,雌雄各半,分4组,分别用生理盐水、ＯＫ-432与ＩＬ-2处理,观察用药后对肿瘤生长的抑制及用抗鼠ＰＣＮＡ单克隆抗体进行ＳＡＢＣ免疫组
OK-432 and IL-2 were used to inhibit the growth of Lewis lung cancer (LLC) and the expression of proliferating cell nuclear antigen (PCNA) in C57BL/6 mice. A total of 40 C57BL/6 tumor-bearing LLC mice were selected and divided into 4 groups. They were treated with normal saline, OK-432 and IL-2. The inhibition of tumor growth after treatment and anti-rat PCNA monoclonal antibody were observed. SABC immunization group
