摘　　要：目的:探讨Ca2+与经络现象之间的联系。方法:采用新型Ca2+生物传感针,实时、动态观测Ca2+在山羊膀胱经腧穴以及非经穴上的分布特性,取“肝俞”“大肠俞”“关元俞”及各穴旁开3cm处为测试点,共记录3min。结果:山羊膀胱经腧穴的Ca2+浓度明显高于旁开对照点(P<0·01或P<0·05)。结论:膀胱经穴Ca2+浓度高于旁开非穴对照点,提示循经脉线上有Ca2+富集现象,其浓度的测定有可能作为鉴别腧穴的重要理化指标。Objective： To explore the relationship between calcium ion and meridian phenomenon. Methods： A total of 10 female goats （30- 35 kg） tranquilized by muscular injection of chlorpromazine hydrochloride （25 mg） were used in the present study. Electrical potential values （reflecting the concentration） of Ca^2＋ in the tissues at ＂Ganshu＂（BL 18）, ＂Dachangshu＂（BL 25）, ＂Guanyuanshu＂ （BL 26） of the Bladder Meridian and 3 control points 3 cm lateral to the abovementioned 3 acupoints were detected by using a needle-type calcium sensor. One minute after insertion of the calcium sensor, the electrical potentials of Ca^2＋ were determined once every 5 sec, continuous for 3 min. Results： The values of electrical potential of calcium ion in the afore-mentioned 3 acupoints were all significantly higher than those in the 3 non-acupoints （P〈 0.01 or P〈 0.05）, which suggests an enrichment phenomena of calcium ion in meridian-points. Conclusion： Calcium ion concentration in BL-18, BL-25 and BL-26 is significantly higher than that of non-acupoint, which may be one of the specificities of acupoint, it suggests that the determination of concentration of calcium ion could be regarded as an important physicochemical marker in identifying acupoints.
