免疫疗法用于治疗人和实验动物的恶性肿瘤已有20余年历史,其中卡介苗(BCG)应用较为广泛。本文使用~(51)Cr短期释放试验研究不同途径注射大剂量BCG(1mg/只)后,大鼠腹腔渗出细胞、脾脏细胞的自然杀伤活性;并用碳酸铁、抗体标记及萤光激活细胞分类仪研究自然杀伤细胞(NK)的细胞核型。本研究还发现BCG可同时活
Immunotherapy has been used for the treatment of malignant tumors in humans and laboratory animals for more than 20 years. BCG is widely used. The short-term release of ~ (51) Cr was used to study the natural killer activity of peritoneal exudative cells and spleen cells of rats injected with large doses of BCG (1mg / kg) by different routes. Iron carbonate, antibody labeling and fluorescent activated cell sorting Instrument to study the natural killer (NK) cell karyotype. The study also found that BCG can live at the same time
