Abstract

This study was investigated the effect of antioxidative vitamin supplementation ($\beta$-carotene 175 mg, vitamin C 200 mg, vitamin E 33.5 mg) for 12 weeks on antioxidant status and autistic related behaviors in autistic children. The antioxidative vitamin-supplemented children had significantly lower concentrations of toxic mineral, such as cadmium (Cd), mercury (Hg) and lead (Pb) in hair, while they had higher concentration of antioxidant minerals (Se, Zn, Fe) in hair. Antioxidant vitamin supplementation for 12 weeks reduced free radical while it increased the hair levels of serotonin compared to the beginning of the study. Additionally, antioxidative vitamin supplementation resulted in significant improvement in social age. These results indicate that the consumption of antioxidative vitamin supplementation for 12 weeks in autistic children may increase plasma antioxidant mineral concentration, resulting in reduced toxic mineral and free radical and improved autistic behavior.

본 연구에서는 소아정신과에서 자폐로 진단받은 아동을 대상으로 항산화비타민을 공급하기 전후를 비교하여 신체 계측과 모발 내 유해 무기질 함량, 혈장 내 항산화 체계를 관찰하였고 혈장 지질 및 간 기능에 미치는 영향, 자폐성향 측정 및 사회성숙도를 비교하였다. 항산화비타민 섭취 전과 후의 영양소 섭취량을 조사한 결과 섭취량에는 큰 차이를 보이지 않았다. 자폐아동에게 3개월간 항산화 비타민을 공급한 후 유해중금속 함량을 측정한 결과는 As, Pb 및 Al의 경우에는 항산화 비타민 공급 후 유의적인 차이를 나타내지 않았으나 감소하는 경향이었다. 그러나 Cd와 Hg은 항산화 비타민 공급 후 유의적으로 감소함을 관찰할 수 있었다. 학습장애에 영향을 미치는 미네랄인 Na, Cr도 항산화 공급 후 감소되어지는 것을 관찰하였으며 여러 항산화 효소들의 구성요소인 Fe, Zn, Mn 및 Se을 관찰한 결과 항산화비타민 공급 후 함량이 증가되었으나 유의적인 차이는 없었다. 혈중 serotonin을 측정한 결과는 항산화 비타민 섭취 전에 비해 섭취 후 serotonin 함량이 다소 증가하였으나 유의적인 차이는 없었으며 free radical 함량은 항산화비타민 섭취 전에 비해 섭취 후 free radical 함량이 23% 유의적으로 감소하였다. 따라서 본 연구를 통해 항산화 비타민이 모발 내 미네랄함량, 중금속 함량, free radical 함량 및 자폐성향 및 사회성숙도에 영향을 미치는 것으로 보아 자폐아동에게 항산화비타민의 보충이 자폐아동의 행동 및 발달장애를 개선시킨 것이라고 사료되어진다.
