作者应用染色体畸变(CA)、姊妹染色单体互换(SCE)和微核实验对倍硫磷、克线磷、灭多威、涕灭威、代森锌、杀虫环、杀虫磺、磷胺等9种农药,以及氯丁二烯的遗传毒性进行了检测,结果如下: CA和SCE实验动物选用200克左右Wi-star雄性大鼠,每组6只。9种农药各按其L D_(50)的1/2 1/10和1/20的剂量灌胃染毒,阴性对照给予蒸馏水,阳性对照腹腔注射环磷酚
The authors used the methods of chromosome aberration (CA), sister chromatid exchange (SCE) and micronucleus test to analyze the effects of fenthion, trimethoprim, methomyl, aldicarb, dexamethasone, insecticidal ring, Phosphate pesticides and nine kinds of pesticides, as well as the genotoxicity of chloroprene were tested, the results are as follows: CA and SCE experimental animals selected about 200 grams of Wi-star male rats, 6 in each group. The nine pesticides were intragastrically administrated at a dose of 1/2 1/10 and 1/20 of their L D_ (50), while the negative control was given distilled water. The positive control was injected intraperitoneally with cyclophosphamide
