The effect of the scent of the test sample on the level of consciousness using a racemate of theaspirane, 2S-theaspirane, and 2R-theaspirane diluted with ethanol to a concentration of 0.1% by mass as the test sample investigated.
As the racemic body of theaspirane, 2S-teaspiran, and 2R-teaspirane, those manufactured by Takasago International Corporation were used.
まず、本実施例において鎮静効果の確認のために採用した試験方法について説明する。
（ＣＮＶ測定による意識水準評価試験の方法について）
事象関連電位のひとつである随伴陰性変動（ＣＮＶ：Contingent Negative Variation（以下、「ＣＮＶ」と称する。））を測定することにより被験者の意識水準を評価し、鎮静効果の検討を行った。ＣＮＶは、その早期成分の変動の大きさが意識の覚醒水準と正の相関を示し、香りが意識水準に及ぼす効果（精神鎮静/高揚効果）を定量評価できることが報告されている。
First, the test method employed for confirming the sedative effect in this example will be described.
(About method of consciousness level evaluation test by CNV measurement)
The level of consciousness of the subject was evaluated by measuring contingent negative variation (CNV), which is one of event-related potentials, and the sedative effect was examined. CNV has been reported to be able to quantitatively evaluate the effect of a scent on the level of consciousness (mental sedation / uplifting effect), with the magnitude of fluctuation of its early component showing a positive correlation with the level of consciousness.
そこで、２Ｒ−テアスピランの鎮静効果を確認するために、ＣＮＶ測定による意識水準評価試験により検討を行った。
本実施例においては２０歳代女性６名を被験者とした。被験者には予め試験内容を説明し、文書にて試験参加への同意を得た。
本実施例においては、被験者の頭頂部、前頭極部中央、左耳及び右耳に脳波計の白金電極を装着し、被験者の頭頂部の電位Ｃｚ、前頭極部中央の電位Ｆｐｚ、左耳の電位Ａ１、及び、右耳の電位Ａ２を計測した。そして、Ｆｐｚを基準として、Ｃｚ−（Ａ１＋Ａ２）の電位差を算出した。脳波計は、日本光電株式会社製、誘発電位検査装置ＭＥＢ−２２１６を用いた。
Therefore, in order to confirm the sedative effect of 2R-teaspiran, examination was conducted by a consciousness level evaluation test by CNV measurement.
In this example, six women in their twenties were subjects. The test contents were explained to the subjects in advance, and written consent was obtained.
In this example, a platinum electrode of an electroencephalograph is attached to the subject's parietal region, frontal pole center, left ear and right ear, and the subject's parietal potential Cz, frontal pole center potential Fpz, left ear's The potential A1 and the right ear potential A2 were measured. Then, the potential difference of Cz− (A1 + A2) was calculated using Fpz as a reference. As the electroencephalograph, an evoked potential inspection device MEB-2216 manufactured by Nihon Kohden Co., Ltd. was used.
被験者にヘッドフォンでクリック音を聞かせ、クリック音がしてから数秒後に点滅する発光ダイオードの点灯に合わせて手元のスイッチを押すという課題を行なわせ、課題の実行時に発生するＣＮＶを計測した。（Ａ）試験試料の香りを嗅がせる場合は、コットン片に５μｌの試験試料をしみこませ、鼻下に貼付して自然呼吸とともに香りを嗅がせた。（Ｂ）試験試料の香りを嗅がせない場合は、コットン片に５μlのエタノールをしみこませ、十分に揮発させた後にコットン片を鼻下に貼付し、上記課題の一連の動作の間、常に呼吸と共に香りを嗅がせた。試験試料の香りを嗅がせた場合（Ａ）と試験試料の香りを嗅がせない場合（Ｂ）のそれぞれについて、３０回繰り返して各ＣＮＶを計測し、積算したＣＮＶの波形の早期成分（４５０ｍｓ〜１０００ｍｓ）の面積（ＣＮＶ面積値）を取得した。そして試験試料の香りを嗅がせた場合（Ａ）のＣＮＶ面積値と、試験試料の香りを嗅がせない場合（Ｂ）のＣＮＶ面積値とを比較し、テアスピランのラセミ体、２Ｓ−テアスピラン、及び、２Ｒ−テアスピランの意識水準に及ぼす効果を評価した。試験試料の香りを嗅がせた場合（Ａ）のＣＮＶ面積値が、試験試料の香りを嗅がせない場合（Ｂ）のＣＮＶ面積値より減少している場合は、試験試料が意識水準を鎮静化したことを意味し、増加した場合は、意識水準を活性化させたことを意味する。 The subject was asked to listen to the click sound with headphones, and the task of pressing the switch at hand in response to the lighting of the light emitting diode flashing several seconds after the click sound was made, and the CNV generated when the task was executed was measured. (A) In order to smell the scent of the test sample, 5 μl of the test sample was soaked in a piece of cotton and applied under the nose to smell the scent along with natural breathing. (B) If the scent of the test sample cannot be sniffed, soak the cotton piece with 5 μl of ethanol, volatilize it sufficiently, and then apply the cotton piece under the nose. And smelled. For each of the cases where the scent of the test sample was sniffed (A) and the case where the scent of the test sample was not sniffed (B), each CNV was repeatedly measured 30 times, and the CNV waveform early component (450 ms to 1000 ms) area (CNV area value) was obtained. Then, the CNV area value in the case where the scent of the test sample is sniffed (A) and the CNV area value in the case where the scent of the test sample cannot be sniffed are compared, and a racemic body of 2 spirane, 2S-theaspirane, and The effect of 2R-teaspiran on the level of consciousness was evaluated. When the scent of the test sample is sniffed (A), the CNV area value is less than the CNV area value of (B) when the scent of the test sample is not sniffed. If it increases, it means that the level of consciousness has been activated.
（ＣＮＶ測定による意識水準評価試験の結果について）
結果を図１に示した。結果は、試験試料の香りを嗅がせた場合（Ａ）の被験者６名のＣＮＶ面積の平均値と、試験試料の香りを嗅がせない場合（Ｂ）の被験者６名のＣＮＶ面積の平均値とを比較して示した。図１において、白色のバーが試験試料の香りを嗅がせない場合（Ｂ）、黒色のバーが試験試料の香りを嗅がせた場合（Ａ）のＣＮＶ面積値を示している。また、一対の標本によるt検定を実施し有意差検定を実施した。
(About the result of the consciousness level evaluation test by CNV measurement)
The results are shown in FIG. The results are: the average value of CNV area of 6 subjects when smelling the test sample (A), and the average value of CNV area of 6 subjects when not smelling the test sample (B) Are shown in comparison. In FIG. 1, the CNV area value is shown when the white bar cannot smell the test sample (B) and when the black bar smells the test sample (A). In addition, a t-test with a pair of specimens was performed, and a significant difference test was performed.
図１から明らかな様に、２Ｒ−テアスピランの香りを嗅がせた場合には、香りを嗅がせない場合に比べて、統計的に有意にＣＮＶ面積値を減少させており（＊ｐ＜０．０５）、意識水準は鎮静化していることがわかる。一方、テアスピランのラセミ体の香り、及び、２Ｓ−テアスピランの香りを嗅がせた場合には、いずれも有意な影響を及ぼさないことがわかる。
このことから、２Ｒ−テアスピランは、テアスピランのラセミ体、及び、２Ｓ−テアスピランに比して、顕著に意識水準を鎮静化することがわかった。
以下、本発明の鎮静効果付与剤の好適な実施例について詳しく説明するが、本発明はこれらに限定されるものではない。
As can be seen from FIG. 1, when the scent of 2R-teaspiran was allowed to smell, the CNV area value was statistically significantly decreased (* p <0. 05), it can be seen that the level of consciousness has subsided. On the other hand, it can be seen that when the scent of the racemic form of theaspiran and the scent of 2S-theaspiran are made to smell, neither has a significant effect.
From this, it was found that 2R-teaspirane markedly calms the level of consciousness compared to the racemic form of theaspirane and 2S-teaspirane.
