塑料笼器具是当前国内外饲养实验动物普遍使用的容器。为获得可靠的实验动物,容器的材料应是安全无毒的。评价这种材料毒性的方法有很多。目前,用体外细胞培养技术评价材料的毒性,越来越受到重视。为对饲养实验动物的塑料笼器具进行安全性评价提供资料,我们做了细胞毒性 Plastic cage appliances are commonly used containers for domestic and foreign experimental animals. In order to obtain reliable laboratory animals, the material of the container should be safe and nontoxic. There are many ways to evaluate the toxicity of this material. At present, more and more attention has been paid to evaluate the toxicity of materials by cell culture in vitro. To provide information on the safety evaluation of plastic cage appliances for experimental animals, we performed cytotoxicity
