云锡矿粉中钒和锆的细胞转化实验

云锡矿工肺癌高发,昆明医学院病理教研室曾分别用矿粉、矿粉加吸氡以及冶炼厂烟尘诱发金仓鼠肺癌均获成功。矿粉及烟尘中含有30余种相似的化学成分,为了排除其中微量放射元素的致癌作用,证实非放射性无机化学成分与肺癌发生是否有关,并逐步缩小矿粉及烟尘中致癌因素的研究范围,本实验选择两者中共有的钒(V)和错(Zr)进行体外细胞转化实验,结果:①钒和锆细胞毒性试验阳性;②钒的细胞转化实验阳性,锆为阴性。目前国内外尚未见报导。

Cell Transformation Test of Vanadium (V) and Zirconium (Zr) in Yunnan Tin Mine Dust

There is a high incidence of lung cancer among the miners of Yunnan Tin Mine. We have successfully induced lung cancer in hamsters separately by mine powder, mine powder plus radon or flue dust of the refinery. There are more than thirty similar chemical elements in both mine and flue dust. In order to exclude the action of the trace radioactive chemical elements and to confirm the carcinogenic effect of the non-radioactive inorganic chemical substances, We choose vanadium (V) and zirconium (Zr) to carry out cell transformation test in vitro. The results are as follows: 1. The cell toxicity test of V and Zr is positive.2. The cell transformation test of V shows positive and that of Zr is negative. This is reported for the first time.
