Abstract : 「抄録」 唾液中のロダンに関する報告は多く, 喫煙者および妊婦などに多量に排泄されるといわれている. 生体内におけるロダンの生成は, シアン化合物, タンパク代謝, 硫黄代謝などに関係があり, 生理化学的意義については, シアンの解毒と考えられているが, いまだ不明の点も多い. そこで, 実際に健康な日本人成人の唾液斑および尿斑を作成し, ロダン含有量により喫煙者, 非喫煙者の識別が可能か否かについての検討を行った. その結果, 唾液と尿とのロダン量の相関係数はr=0.7435(t0=9.8359, P<0.001)で, 相関関係が認められた. その平均値は, 唾液で10.77±5.79mg/dl, 尿で1.83±0.05mg/dlであった. 喫煙者と非喫煙者に分けた場合, 個体により変動はみられたが, その平均値は明らかに差が認められた(唾液-非喫煙者:4.6±2.785mg/dl, 喫煙者:13.74±4.30mg/dl, 尿-非喫煙者:1.22±0.41g/dl, 喫煙者:2.17±0.53mg/dl). 1日平均の喫煙本数別では, 本数によりロダン量に差がみられ, 本数が多ければロダンも多量に検出された, 斑痕からの検査では, 生の試料同様, 喫煙者, 非喫煙者のロダン量は平均値であるが, 明らかに喫煙者に優位の差が認められた. 試料別に比較すると, ロダン量はナイロン糸では少ない傾向がみられたが, 他の試料同士では, その差はほとんど認められなかった. また, 実際にロダン量から喫煙者, 非喫煙者の識別を行うには, 1日平均30本以上喫煙する個体でその可能性があるものと思われた.

Abstract : Many studies have been made on rhodane contents in saliva, with the results that much rhodane is found in excretion of smokers and pregnant women, that the formation of rhodane in the living creature has something to do with cyanide compound, protein metabolism and sulfur metabolism, and that rhodane is thought to have a chemico-physiological signification because of its having an antidotal virtue against cyanide. The present study deals the possibility of using rhodane contents in saliva in individual identification pertaining smoker or non-smoker. The materials were saliva stains and urine stains obtained from healthy Japanese adults. The result was as follows : The coefficients of correlation of rhodane in saliva and urine were r=0.7435 (to=9.8359, p<0.001), indicating the existence of correlationship between them. The mean values of rhodane in saliva and urine were 10.77+-5.79mg/dl and 1.83+-0.05mg/dl, respectively. In the investigation by smoker and non-smoker, the mean value showed distinct difference between the two although there were individual variation. By the number of cigarettes consumed per day, it was clarified that the amount of rhodane increased in direct proportion to the number of cigarettes consumed. In the investigation by the use of stains, the amount of rhodane in the smokers was greater than that in the non-smokers in the mean value, similar to the results obtained from living subjects. Furthermore, by the kind of materials examined it was found that, whereas nylon seemed to have a property of holding less amount of rhodane, other materials showed almost no difference among them. It was concluded that in the individual identification of smoker and non-smoker, the method of using saliva or urine stain is effectual in the case of individuals whose average daily consumption of cigarettes is more than thirty.
