2、x射线照射I型糖尿病小鼠,检测不同时间点小鼠体质量、血糖和肾功能改变情况,为低剂量照射用于预防和治疗糖尿病提供实验证据.方法建立I型糖尿病小鼠动物模型,用血糖仪和全自动生化监测仪测量血糖、检测尿液中尿肌酐及尿白蛋白的含量.结果I型糖尿病小鼠体质量显著低于非糖尿病组(P<0.05).给予剂量为25mGyx射线照射后,各组小鼠体质量无显著性差异.低剂量照射使糖尿病组小鼠血糖水平受到了抑制,显著低于糖尿病组(P<0.05).照射后2—16周,糖尿病组尿肌酐、白蛋白含量与糖尿病照射组比较差异具有统计学意义(P3、水平,还能有效降低I型糖尿病小鼠尿中自蛋白含量,促进尿肌酐的排出,从而缓解由糖尿病高血糖引起的肾脏损伤.关键词:低剂量电离辐射;I型糖尿病小鼠;血糖;肾功能中图分类号:Q691文献标志码:A【引用格式】张晶,赵大力,谢忠伟,等.低剂量电离辐射对I型糖尿病小鼠血糖和肾功能影响的实验研究[J].北华大学学报:自然科学版,2015,16(1):30—33.ExperimentalStudyontheInfluenceofLowDosesIonizingRadiationonBloodGlucoseandRenalFunctioninDiabetesMiceZhangJing,Zha4、oDali,XieZhongwei,LiuYanjun。,QiYali。(1.SchoolofPublicHealth,BeihuaUniversity,Jilin132013,China;2.JilinCityEntryandExitInspectionandQuarantineBureau,filin132012,China;3.People’SHospitalinChangchunCity,Changchun130021,China)Abstract:ObjectiveProvideexperimentalevidencesfortheeffectoflowdoseir5、radiationonthepreventionandtreatmentofdiabetes,byexaminingbodyweight,bloodglucoselevelandrenalfunctionchangesintypeImiceatdifferenttimes.MethodAftertypeIdiabetesmicemodelwasestablished,bloodglucoselevel。contentsofcreatinineandalbumininurineofthemiceweremeasuredwithglucosemeterandautomaticbi6、ochemicalmonitor.ResultsTheweightoftypeIdiabetesmiceweresignificantlylowerthanthatofthenon.diabeticgroup(P<0.05).Under25mGyX—ray,thebodyweightofeachgrouphadnosignificantdifferenceinmice.Lowdoseirradiationrestrainedthebloodglucoselevelindiabeticmice.whichwassignificantlylowerthanthatofthemod7、elgroup(P<0.05).Fromweek2toweek16afterradiation.theconcentrationsofurinecreatinineandurinaryalbuminshowedstatisticaldifferencesinthediabetesmicecomparingwiththeX.rayexposuregroups(P<0.05).ConclusionLowdoseirradiationwasabletoprotectthetypeIdiabetesmice,t
