1) Strontium-90 level was determined in May 1989 in 40 sample groups of Japanese teeth, for a total of 1022 third molars, obtained from donors born in 1900-1970.2) The teeth from donors born in 1925-1931, and which were extracted in the donors' twenties did not contain detectable strontium-90.3) Strontium-90 level of the teeth from donors born in and after 1942 suddenly increased, and reached peak value of 62.8 to 72.8mBq/g Ca in 1953. It abruptly decreased after 1954 and reached approximately 20mBq/g Ca by 1970.4) In the teeth obtained from donors born in 1900-1924, and which were extracted at the age of 30 to 69, a small amount of strontium-90 was detected.

高性能個人用計算機向けOSを,データ抽象機能を持つ言語CLUを用いて開発した.本システムの基本設計は1985年秋に開始され,現在NEC PC-98XA/XL計算機上で中核部分(記憶域管理,プロセス管理,モジュール管理),ファイルシステム,CLUコンパイラ,ウィンドシステム,ネットワークモジュールおよびいくつかの応用プログラムが動作している.本システムは単一言語系の考え方を採用することにより,コンパクトで見通しのよいシステムにできた.またCLU言語のデータ抽象機能は,モジュール間の独立性を高め,分かりやすく構造化されたシステムとする上で効果があった.

An analytical method for the determination of aromatic compounds exhalated from hand skin has been proposed. The sampling of exhalated aromatic compounds was performed as follows: after the intake of aromatic compounds included in chewing gum or a capsule, exhalated skin gas was collected from a hand. The hand was covered with a sampling bag of poly vinyl fluoride (PVF) for 30 min. Then, the inner space of the sampling bag was sprayed with a 25% of ethanol aqueous solution. After removing the hand from the bag, the trapped solution containing skin gas was collected. The aromatic compounds in the trapped solution were extracted to the solid phase as Twister® (stir bar coated with poly dimethyl siloxane, Gerstel). Extracts were determined by gas-chromatograph mass spectrometry using a thermo desorption system and a selective ion mode. Linalool, citronellol and geraniol, which are the main components of rose essential oil, were detected from the skin of a hand after an oral intake of rose oil. The exhalated absolute amount of linalool, citronellol and geraniol increased in 30 to 60 min, and then decreased after intake. The recoveries of linalool, citronellol and geraniol were 53.5%, 66.7% and 55.1%, respectively. The correlation coefficient of the standard curves for linalool, citronellol and geraniol were 0.9977, 0.9994 and 0.9987, respectively. Each compound exahalated from the skin of a human body during 6 hours after intake was estimated to be, according to the amount of intake, 0.39%, 0.09% and 0.25%, respectively, for one subject. The absolute amount of geraniol exhalated from a hand increased significantly after oral intake for 8 subjects (P<0.025). This is the first report to present hard proof that an aromatic compound was exhalated from human skin after its intake as food.
