链球菌-722是类似于日本OK-432(商品名picihanil)的制剂,是一种抗肿瘤的非特异性免疫制剂。在体外实验中,证实对肿瘤细胞具有抑制与杀灭作用。在临床试用中,单独局部注射治疗口腔鳞癌,显示一定的疗效。据文献报道,OK-432有促进机体细胞免疫功能的作用。本实验提示链球菌-722制剂可促进人NK细胞活性,现报道如下。 Streptococcus-722 is a preparation similar to Japanese OK-432 (trade name picihanil) and is an anti-tumor non-specific immunological preparation. In vitro experiments confirmed the inhibition and killing of tumor cells. In clinical trials, local injection of oral squamous cell carcinoma alone showed a certain effect. According to reports in the literature, OK-432 has a role in promoting cellular immune function. This experiment suggests that streptococcal-722 preparations can promote human NK cell activity and are reported below.
