鲨鱼软骨提取物（sharkcartilageactiveextract，SCAE）在体外细胞实验中，当浓度为50μg／ml时，对肿瘤细胞的抑制率是50．2％～60％。在小鼠移植瘤实验中表明，SCAE作用最佳的是分子量1×104～5×104部位。小鼠口服SCAE24～72mg／d的抑瘤率是54％～67％，小鼠注射SCAE6～18mg／d的抑癌率是67％～82．2％。SCAE有溶于水，用量小等特点。
In shark cartilage active extract (SCAE), in vitro cell experiments, when the concentration was 50 μg/ml, the inhibition rate of tumor cells was 50.2% to 60%. In mouse xenograft experiments, the best effect of SCAE was at a molecular weight of 1 x 104 to 5 x 104 sites. The inhibition rate of oral SCAE from 24 to 72 mg/d in mice was 54% to 67%, and the tumor suppression rate in mice injected with SCAE from 6 to 18 mg/d was 67% to 82.2%. SCAE is soluble in water and has a small amount of usage.
