本文采用IHA对125例弱智儿童、68例正常人及19对弱智儿童母子弓形虫感染情况进行了调查,同时检测了26例感染弓形虫的弱智儿童,38例未感染弓形虫的弱智儿童和28例正常儿童血清IgG、IgA、IgM和补体C_3含量。结果表明,弱智儿童弓形虫感染率20.8％,明显高于对照组(4.41％)(P<0.01),提示弓形虫感染与智力低下密切相关.弓形虫血清抗体阳性弱智儿童与未感染弓形虫的弱智儿童和正常儿童血清IgG、IgA和IgM含量无差异(P>0.05),说明血清抗体与弓形虫感染关系不大;弓形虫抗体阳性弱智儿童血清补体C_3含量0.93±0.35g/l,明显低于正常儿童1.68±0.64g/l(p<0.001),提示补体G_3含量降低与弓形虫感染密切相关.
In this paper, IHA 125 cases of mentally retarded children, 68 normal subjects and 19 pairs of mentally handicapped children infected with Toxoplasma gondii were investigated, while 26 Toxoplasma gondii mentally retarded children, 38 Toxoplasma gondii mentally retarded children and 28 Cases of normal children serum IgG, IgA, IgM and complement C_3 content. The results showed that the infection rate of Toxoplasma gondii in children with mental retardation was 20.8%, which was significantly higher than that in control group (4.41%) (P <0.01), suggesting that Toxoplasma gondii infection was closely related to mental retardation. Serum IgG, IgA and IgM levels in mentally retarded children and normal children had no significant difference (P> 0.05), indicating that the serum antibody had little to do with Toxoplasma gondii infection; the serum complement C_3 of Toxoplasma gondii-positive mentally retarded children was 0.93 ± 0.35g / l The normal children 1.68 ± 0.64g / l (p <0.001), suggesting that the reduced complement G_3 content and Toxoplasma infection are closely related.
