To investigate possible functions of acupuncture, oxygen (O(2)) levels were measured at two different acupuncture points (APs) [Hegu and Laogong] and at the corresponding non-APs (3-5 cm away from the APs) in real time using a high sensitive electrochemical O(2) microsensor. The sensor had a small planar sensing platinum disk (diameter = 25 microm) and therefore was able to monitor the O(2) levels at the localized APs. Significantly higher O(2) levels (p < 0.05) were observed at both APs (n = 5, without exceptions) in comparison with the non-APs. Sufficient sensor sensitivity to distinguish the O(2) level differences between APs and non-APs was achieved. This research provides useful information on possible functions of APs and meridians.
为研究针刺的潜在作用，使用高灵敏度电化学氧微传感器实时测量了两个不同穴位（合谷和劳宫）及其相应非穴位（距穴位3 - 5厘米处）的氧（O₂）水平。该传感器有一个小型平面传感铂盘（直径 = 25微米），因此能够监测局部穴位处的氧水平。与非穴位相比，在两个穴位处（n = 5，无一例外）均观察到显著更高的氧水平（p < 0.05）。实现了足够的传感器灵敏度以区分穴位与非穴位之间的氧水平差异。本研究为穴位和经络的潜在作用提供了有用信息。
