新疆与天津两地区部分成人血清抗氧化状态比较

Comparison of the Serum Antioxidantion Status of Adults in Xinjiang and Tianjin

目的研究不同地域间部分成人血清抗氧化状态的差异及其影响因素。方法抽样调查新疆与天津地区74名男、女成人血清总抗氧化能力(TAOC)、超氧化物歧化酶(SOD)和丙二醛(MDA)水平。结果新疆地区成人TAOC和SOD水平显著高于天津地区(P<0.001),两地区间MDA水平差异无显著性。新疆地区TAOC水平女性显著高于男性(P<0.01);天津地区未显示明显差异。新疆组TAOC有随年龄增高而降低的趋势,天津组SOD、MDA有随年龄增高而升高的趋势。结论新疆地区居民在受日照时间长、紫外线辐射量多的情况下,仍能使机体维持良好的抗氧化状态,可能是由于机体在一定范围内所具备的代偿能力和饮食习惯不同所致。

Objective To study the differences in serum antioxidant ion status of adults living in different regions and relat-ed influential factors.Methods Serum levels of total antioxidation capacity(TAOC),superoxide dismutase(SOD)and malon-dialdehyde(MDA)were determined in37local residents in Xinjiang(Xinjiang group)and37Tianjin residents(Tianjin group).Results Serum levels of TAOC and SOD were significantly higher in the Xinjiang group than that in the Tianjin group(P<0.001),while there was no statistical difference(P>0.05)for the MDA between the two groups.The TAOC levels were sig-nificantly higher in the females than that in the males(P<0.01)in Xinjiang group,but no difference in sex was found in the Tianjin group.The serum levels of TAOC in Xinjiang residents tended to decrease with increasing age.The levels of SOD,MDA in Tianjin residents tended to increase with age.Conclusion The results suggested that residents in Xinjiang still maintained good serum antioxidative activity despite living under the conditions of more sunlight and ultraviolet radiation,which might be caused by the bodys intrinsic compensatory abilities with a definite range for local residents in Xinjiang and their different di-etary habits.
