Comparison of Acupuncture Effect on Blood Perfusion between Needling Nonacupoint on Meridian and Needling Nonacupoint off Meridian.

To verify the ancient theory of rather missing the acupoint than missing the meridian, acupuncture at nonacupoint on meridian and acupuncture at nonacupoint off meridian were performed, respectively. The blood perfusion (BP) on the calf around bladder meridian area was measured with a laser Doppler perfusion imager before, during, and after acupuncture. The whole scanning field was divided into seven subareas, and mean BP on each area was calculated.

[Experimental verification of "treating lumbar-back problems by puncturing Weizhong (BL 40)" with blood perfusion imaging technique].

Objective: To verify the classic saying of "Treating lumbar-back problems by puncturing Weizhong (BL 40)" in acu-moxibustion learning and to explore its underlying mechanism.

Methods: Forty volunteer sublects were asked to accept twice tests respectively, i.e.

[Re-discrimination on "reinforcement can be achieved by slow-yet-rapid needling, and rapid-yet-slow needling weakens evil qi"].

Objective: To study on the original meanings of "reinforcement can be achieved by slow-yet-rapid needling, and rapid-yet-slow needling weakens evil-qi", one of important bases of reinforcing-reducing in acupuncture.

Methods: Using the principle of knowledge archaeology and through structure an d through structure analysis on the subjects described by "slow" and "rapid" and the papers appearing the words, the meanings of this sentence are re-discriminated.

Conclusion: "Slow-rapid" prescribed in the reinforcing-reducing needling method in Huangdi's Internal Classic includes 3 subjects: pulse condition, needle-retained time, and velocity of withdrawing the needle.

[Diuretic effect of injecting furosemide into low hydraulic resistance point Shuifen along the conception meridian in pigs with acute edema].

Objective: To observe whether injection of medicine into low hydraulic resistance point along meridian brings about higher medicinal effect and to explore the efficacy of the theory that meridians are made up of channels featuring low hydraulic resistance by observing the diuretic effect of injecting furosemide or saline into the low hydraulic resistance point Shuifen (CV 9), vein and Zusanli (St 36) respectively.

Methods: Acute edema was induced in pigs by rapid intravenous injection of 2 000 ml normal saline. The pigs were divided into four groups: Shuifen (CV 9) injection of half dose furosemide group (SFF group), intravenous injection of full dose furosemide group (VF group), Zusanli (St 36) injection of full dose furosemide group (ZSLF group), and Shuifen (CV 9) injection of half dose normal saline group (SFS group).
