【摘要】 目的分析自然灾害中儿童青少年应激反应后唾液中生化成分的改变。方法以汶川地震灾区236例儿童青少年为研究对象,按照不同地区、不同年龄分组,使用Hitachi 7600全自动生化分析仪对唾液生化成分进行分析。结果在受灾较重的漩口镇人群Ca含量降低,SA含量增高;青少年组Mg、Cl含量较高;对不同地区不同年龄间多因素分析提示Mg、Na、Cl、SA在水磨镇<14岁组水平较高,而漩口镇≥14岁组水平较高。结论突发自然灾害会改变儿童青少年唾液中生化成分,可能与应激程度有关。更多还原

【Abstract】 Objective To analyze the levels of biochemical components in saliva of children and adolescents with stress after sudden natural disasters.Methods A total of 236 children and adolescents from Wenchuan earthquake region were divided into children group and adolescent group according to the regions where they lived and their ages.Levels of biochemical components in their saliva were measured with a Hitachi 7600 biochemical analyzer.Results The Ca levels were lower while the SA,Mg and Cl levels were higher in saliva of adolescents than in children from Xuankou Town(P<0.05).Multi-factor analysis showed that the Mg,Na,Cl and SA levels were higher in children from Shuimo Town than in adolescents from Xuankou Town(P<0.05).Conclusion Sudden natural disasters can change the levels of biochemical components in saliva of children and adolescents,which may be correlated with the severity of stress.更多还原
