足太阳膀胱经阻滞机理的临床研究

目的:验证"外周阻断"的观点,为阐明经络现象的机理和经络的实质提供实验依据.方法:随机对59例患者在针刺昆仑穴的同时按实验要求依次压迫承扶、肾俞、膈俞,以压迫3穴旁开1cm处作为对照组,采用TCD观察压迫前后及解除压迫后对椎动脉血流变化情况的影响.结果:针刺同时压迫穴位可明显阻断针效,而压迫对照组则不能阻断针效,均P＜0.01.结论:压迫膀胱经不同段的穴位均可阻断针刺的效应,这种阻断效应只有施加在经线上才能表现出来.提示针刺过程中外周可能确实存在某种"循经行进的实质性过程".

Clinical study on mechanisms of blocking the Urinary Bladder Meridian of Foot-Taiyang

Objective To test and verify the peripheral blocking action of the Urinary Bladder Meridian and to provide experimental basis for expounding the mechanism of meridian phenomenon and essence of meridians. Methods Fifty-nine cases were treated by acupuncture at Kunlun (BL 60),at the same time,Chengfu (BL 36) was pressed in 20 cases of them,Shenshu (BL 23) was pressed in 20 cases and Geshu (BL 17) was pressed in 19 cases,and pressing the points at 1 cm lateral to Chengfu (BL 36),Shenshu (BL 23) and Geshu (BL 17) were used as control points respectively. Changes of velocity of blood flow in vertebral artery were investigated by TCD before and after pressing and after removing the pressing. Results Pressing acupoints at the same time of acupuncture could significantly block the acupuncture effect,but pressing the control points could not block the acupuncture effect ( P <0.01). Conclusion Pressing acupoints at different segments of the Urinary Bladder Meridian can block the effect of acupuncture,indicating that a certain essential moving process along channel possibly occurs in the periphery du-ring acupuncture.
