Abstract:
Objective To investigate the protective effects of soybean isoflavone(SI) on genetic toxicity induced by di-n-butul phthalate(DBP) in mice.Method(1) Micronucleus test:40 male 7 w old Kunming mice were randomized into 4 groups:High and low dose SI intervention groups,DBP model group,and solvent control group.SI intervention groups were given different doses of SI(50,100mg/kg) for 30 d,meanwhile,the DBP group and solvent group were given 0.5% sodium carboxymethyl cellulose.Then all groups were treated by 0.5g/kg DBP for 5d except solvent group.Mice were sacrificed 6 hour after last treatment,and then counting micronucleated cells in bone marrow.(2) Sperm malformation test:40 male 6w old Kunming mice were grouped and treated the same as micronucleus test.Mice were sacrificed at 35 day after the first treatment,and then sperm quantity,motility,viability and abnormality rate were calculated.Result Micronucleus rate and sperm abnormality rate of SI intervention group were lower than DBP model group,while sperm motility and viability were higher than DBP model group.Conclusion SI can relieve the genetic toxicity induced by DBP in mice.
