Inhalation toxicity of cyfluthrin for 28-day repeated dose in rats
摘要
Abstract
Objective To determine the inhalation toxicity and find the non -observed adverse effect level (NOAEL) of cyfluthrin for a 28-day repeated dose in rats. Methods Clean-grade SD rats were randomly divided into 5 groups with 5 females and 5 males in each. The animals inhaled DMSO or cyfluthrin at the concentration of 0, 7. 81 , 9. 05 and 18. 98 mg/m for 4 weeks (6 h/d, 5 d/w). At the end of inhalation , all the animals were kindly sacrificed. Their organs were collected for histopathological examination . Blood samples were collected for analysis of complete blood count , biochemistry and coagulation. Results The animals in 18. 98 mg/m3 group were found scratching repeatedly around the mouth, listless, fidgeting, trembling, discharging blood around the mouth and nose . However, symptoms in females were less serious than in males. Furthermore , the body mass , feed efficiency , weight of kidney of animals in this dose male group were found decreased compared with the control group . Biochemistry detection revealed that serum AST was elevated markedly in both genders of 18. 98 mg/m3 group and in males of 9. 05 mg/m3 group. No obvious abnormity was found in 7.81 mg/m3 group or control group. Conclusion Based on the results above, the non-observed adverse effect level (NOAEL) of cyfluthrin in SD rats is 7. 81 mg/m3 for 28 d repeated inhalation in this study.关键词
