摘要
采用自化学电离ＧＣ／ＭＳ技术，以氘水为人体内示踪剂（０．６ｇ／ｋｇ体重），测定了氘水在５例成人体内的平衡速度，并比较了在血、尿和唾液样品中的异同。根据摄入氘水后２．５、３．０、３．５小时唾液中同位素的平均稀释程度计算了一组正常中国成人体内总体水（ＴＢＷ）等参数。
Equlibrium speeds of D_2O administered orally in 5 normal adults were measured with the technique of self-chemical ionization on GC/MS.The variations of D_2O in serum,urine and saliva werecompared too.The total body water(TBW)in 6 normal Chinese adults were determined according tothe average dilution in the saliva at 2.5,3 and 3.5 hours after D_2O intake at the dosage of 0.6g/kgbody weight.
