本文旨在比较A蛋白类制剂(SPA、SAC和SAW)与CP的体内抗肿瘤效应,确定它们的免疫保护强度,寻找提高其免疫疗效的方法。结果表明,A蛋白类制剂体内抗实验性肿瘤的疗效接近CP,尽管它们不足以对付10~7瘤细胞(EAC)的攻击,但其疗效可通过与化疗药物的联合应用而提高。 This article aims to compare the in vivo anti-tumor effects of Protein A (SPA, SAC, and SAW) and CP, to determine their immunoprotective strength, and to find ways to improve their immune response. The results showed that the efficacy of protein A preparations against experimental tumors in vivo was close to that of CP, although they were not sufficient to deal with 10 to 7 tumor cells (EAC) attacks, but their efficacy could be improved through the combined use of chemotherapeutic drugs.
