为探讨蚊香烟雾对生物体细胞的遗传毒理效应,我们应用紫露草微核技术对此作了研究。1 材料与方法采用由南京植物研究所引进的美国沼泽紫露草(Tradescantia paludosa)3号敏感品种,由本室室外栽培供实验用。将紫露草花枝插入盛满蒸馏水的烧杯中,每个实验组插15支花序,放入有机玻璃染毒柜,点燃一盘蚊香或使用一片蚊香片(均为市售),使紫露草花枝接
In order to explore the genotoxic effects of mosquito-repellent tobacco smoke on living cells, we applied this method to investigate the genetic toxicity of mosquito-repellent incense. 1 Materials and Methods The sensitive cultivars of Tradescantia paludosa 3 introduced by Nanjing Institute of Botany were cultivated in our laboratory for experiment. Will flowering branches inserted into the beaker filled with distilled water beaker, each experimental group inserted 15 inflorescences, into the plexiglass poison cabinet, lit a mosquito coil or use a piece of mosquito (both commercially available), so that the flowering branch
