为了探讨几种化合物对温石棉促人胚肺（ＨＥＬ）细胞增殖作用的影响，用不同浓度的柠檬酸铝、混合稀土或亚硒酸钠溶液浸泡温石棉１小时后，再将其与人胚肺细胞共同孵育，通过测定［３Ｈ］ＴｄＲ掺入量，来了解人胚肺细胞的增殖状况。结果显示，２．５～１０μｇ／ｍｌ的温石棉、时间作用在２４小时之内，或２０～８０μｇ／ｍｌ温石棉、时间作用在６小时之内均可促使人胚肺细胞增殖。与未处理温石棉组相比，经三种化合物处理的温石棉其促细胞增殖作用明显下降。提示，采用三种化合物溶液浸泡温石棉，有可能减轻温石棉的致癌危害性
In order to investigate the effects of several compounds on the proliferation of human embryo lung (HEL) cells induced by chrysotile, chrysotile was treated with different concentrations of aluminum citrate, mixed rare earths or sodium selenite solution for 1 hour, and then mixed with human embryos Co-incubation of lung cells, by measuring the [3H] TdR incorporation, to understand the proliferation of human embryonic lung cells. The results showed that 2.5 ~ 10μg / ml of chrysotile, the role of time within 24 hours, or chrysotile 20 ~ 80μg / ml, time within 6 hours can promote human embryonic lung cell proliferation. Compared with untreated chrysotile, the three compounds treated chrysotile significantly decreased its role in promoting cell proliferation. Tip, the use of three compounds soaking chrysotile solution, may reduce the carcinogenicity of chrysotile asbestos
