应用体外溶血试验，就混合稀土、亚硒酸钠、柠檬酸铝对温石棉溶血活性的影响进行了研究。结果显示，用上述三种化合物浸泡温石棉纤维，均可抑制其溶血活性，并且随着温石棉浓度的升高，抑制作用愈加明显。表明用上述三种化合物浸泡温石棉纤维，均可降低其体外细胞毒性。 The effect of mixed rare earth, sodium selenite and aluminum citrate on hemolysis of chrysotile was studied by in vitro hemolysis test. The results showed that soaking chrysotile fibers with the above three compounds all inhibited the hemolytic activity, and the inhibitory effect became more obvious as the concentration of chrysotile asbestos was increased. These results indicate that soaking chrysotile fibers with the above three compounds can reduce their in vitro cytotoxicity.
