【摘要】 目的建立唾液碘的测定方法,探讨唾液碘与尿碘的相关性。方法用酸消化砷铈催化分光光度法测定33例青年男女正常健康志愿者不同时间的唾液及尿液中的碘含量。结果健康志愿者的唾液碘及尿碘均呈偏态分布,其中位数值分别为102.7μg/L和215.6μg/L。男女性别之间无显著性差异,且随取样时间不同,唾液碘及尿碘变化曲线也不相同。由所测数值进行统计学分析推算出18～22岁成人组唾液碘的正常值范围为70～150μg/L,尿碘的正常值范围为130～280μg/L。结论唾液碘与尿碘间存在着较好的相关性。更多还原

【Abstract】 Objective To develop a method of monitoring con centrations of iodine in salivary sa mples and study the rela-tionship between iodine in saliva an d urine.Methods The salivary and urine samples were g ot from 33healthy volunteers at 8,10,14,16,18,20o ’clock,respectively.We determined the iodine in these samples by using t he methods of acid digestion and ar-senic -cerium catalytic spectrophotometry.Results The median values of urinary and sali vary iodine were 215.6μg /L and102.7μg /L,respectively,their distribut ion curves are skew.There was no sign ificant difference between male and female(P>0.05).However,the curve of urine iodine within 12hours looked like a sine curv e and peak value is higher than that of salivary curve.But the curve of salivary iodi ne looked like a line,peak value is not high.According to statistic analy sis,we have got the nor-mal iodine range of saliva and urine i n 18～22years old healthy adults.They are 75～150μg /L and 130～280μg /L,respective-ly.Conclusion The methods of determination of salivary iodine is simple,reliable,acc urate and stable.There is a good rela tion-ship between salivary iodine and urine iodine.The normal iodine range of saliva and urine in 18～22years old healthy adults are75～150μg /L and 130～280μg /L,respectively.更多还原
