        The effect of Lead-X oral solution to lead poisoning children and their immune status

        TAO Xue-mei (Beijing Haidian Hospital pediatric,Beijing  100080, China)

         [Abstract]  Objective: To study the effect of Lead-X oral solution to lead poisoning children and their immune status. Methods: 75 cases of children with mild lead poisoning were randomly divided into two groups, A group (nutrient supplement group) 37 cases, take Centrum300; B group (Lead-X oral solution group) 38 cases, take Lead-X oral solution. The treatment continues for two mouths. Result: After treatment, the average blood lead level and neurobehavioral score of two groups were reduced significantly, B group was better than A group (P <0.01).  Compared with A group, the average level of IFN- was increased, of IL-4 was decreased, and the ratio of IFN- / IL-4 was elevated In B group (P <0.05). Conclusion: Lead-X oral solution can cut down blood lead level, improve neurobehavioral score, and increase immune function of lead poisoning children significantly.
