在研究磁场各种生物效应和开展应用的同时,不可忽视其对生物体可能存在的某些潜在危害。为此我们采用国际上近年发展的监测环境中致遗传毒性微生物学检测方法-Unm法,以及Ames法度从诱导和诱变二个方面来探讨170mT永磁体磁场是否具有致遗传毒性。 一、材料和方法 1.实验磁场 永磁材料制成的医用强力磁片,直径为9毫米 While studying the various biological effects and applications of magnetic fields, some potential hazards to organisms may not be neglected. To this end, we use the internationally developed detection environment in the detection of genetic toxicity of microbiological detection methods-Unm method, and the Ames method from two aspects of induction and mutagenesis to explore 170mT permanent magnet magnetic field is genotoxic. First, materials and methods 1. Experimental magnetic field made of permanent magnet material powerful magnet, a diameter of 9 mm
