中文摘要 | 傳統中醫將人體的表面分成十二皮部,分別歸屬於十二經絡。根據中 醫典籍的記載,每一穴位和每一經絡都有它們特異性的功能。另外,傳統中醫認 為十二經絡的經氣是從五輸穴的井穴開始,而從合穴進入經脈系統,因此本研究 的目的是在探討經絡的特異性和比較同一經絡井穴和合穴之間的異同。對象是 16位醫學生,他們都是健康的自願者。方法是使用皮部微循環測定儀(Laser Doppler flowmetry),以微循環中的血液灌流(blood perfusion),移動血球的濃度 (concentration of moving blood cells),速率(velocity)和能量變化(energy index) 為指標。所有的受測者都分別接受以下三種試驗: 1)假刺激組,沒有電針刺激; 2)穴位組,使用2Hz的電針於右側合谷穴刺激;3)非穴位組,使用2Hz的電針於 離右側合谷穴位外3公分的位置刺激。每個試驗都分為電針前期、電針期和電針 後期,每期是20分鐘。我們也較電針前期、電針期和電針後期的右側大腸經的 井穴商陽穴和合穴曲池穴區微循環的變化。另外,也比較穴位組的右側曲池穴和 尺澤穴區微循環的變化。結果顯示在休止狀態下商陽穴處有較大微循環的血液灌 流、移動血球濃度和動能量(kinetic energy),2Hz電針刺激合谷穴位區或非穴位 區兩者都能引發商陽穴和曲池穴區微循環的改變,但兩者間的變化形式(pattern) 不同。同樣的,刺激右側合谷穴所引發曲池穴和尺澤穴區間微循環的變化形式也 不同。 結論是由於指端區比肘端區有較豐富的動靜脈的吻合,所以它在靜態下商陽 穴擁有比曲池穴較高微循環的血液灌流、移動血球濃度和動能量。2Hz電針合谷 穴或非穴位都引發商陽穴區和曲池穴區,以及曲池穴區和尺澤穴區間微循環的變 化,但他們之間的變化形式不同,這些說明內位和經絡的特異性是存在的。 |
英文摘要 | In order to investigate the belonging of cutaneous microcirculation (MC) to the meridian system and the differences of cutaneous MC between finger pulp and elbow portion in the same meridian system. 16 healthy male volunteers were studied. We used laser Doppler flowmetry to measure the MC, with the blood perfusion, concentration of moving blood cells, velocity as well as the energy index to be the parameters. Three assessments were performed in each subject over a period of at least three days. Each assessment was divided into pre-electroacupuncture (EA) period with no EA stimulation, followed by an EA period, and then a post-EA period. Each period was 20 min. Three assessments were performed as follows: 1) Sham: no stimulation was performed, 2) Acupoint: 2Hz EA was applied to right Hoku acupoint; 3) Non-acupoint: 2Hz EA was applied to 3cm lateral to right Hoku acupoint. The MC on the right Shangyang (LI-1) and Quchi (LI-l1) acupoint regions were measured. In addition, the MC of Quchi and Chize (Lu-5) acupoint regions were measured simultaneously in the acupoint group. Our results showed that the perfusion, concentration of moving blood cells and kinetic energy were greater in the Shangyang acupoint regions than those in the Quchi acupoint regionin the resting state. 2Hz EA applied to Hoku acupoint or non-acupoint could induce the changes of MC in the Shangyang and Quchi acupoints region, but the patterns of changes between them were not similar.Likewise, 2Hz EA applied to Hoku acupoint induced the patterns of MC changes were different between Quchi and Chize acupoints region. In conclusion, the perfusion, concentration of moving blood cells and kinetic energy are greater in the Shangyang acupoint region than those in the Quchi acupoint region in resting state, suggesting these results resulting from the existence of arteriovenous anastomsis on the finger pulp. The different patterns of cutaneous MC changes between Shangyang and Quchi acupoints regions induced by 2Hz EA on both Hoku acupoint and non-acupoint, and the different patterns also are found between Quchi and Chize acupoint region induced by 2Hz EA stimulation of Hoku acupoint, these results response to the specific property of acupoint and meridian system. |
