Abstract: ObjectiveTo assess the effects of taurine supplementation on development of youngrats ex posed to low-level lead.MethodsLow level poisoning lead model of rat was set up in order to observe the protection of supplementing different dose of taurine on the normal development of rat's offspring.The adolescent's blood lead,cerebral lead were measured.ResultsYoungrat's cerebral-lead contents of all taurine-supplementation groups were low than lead groups,higher than control group(P<0.01).The time(day)of negative tendency,aural stun,cirrus locat ion of lead+taurine groups is shorter long lead group(P<0.01).ConclusionSupplementing taur ine could reduce lead deposit in youngrat's brain and prevent retardation on behavioral development from lead poison.
