Three-dimensional (3D) topographic structures of acupuncture points were investigated by using synchrotron radiation in-line X-ray phase contrast computerized tomography. Two acupuncture points, named Zhongji (RN3) and Zusanli (ST36), were studied. We found an accumulation of microvessels at each acupuncture point region. Images of the tissues surrounding the acupuncture points do not show such...

OBJECTIVE To investigate the dynamics underlying the sustained effect of acupuncture as a possible explanation of earlier findings that acupuncture stimulation at the vision-related acupuncture point, GB37, cannot specifically change the functional MRI (fMRI) signals of the visual cortex compared with stimulation at an adjacent non-meridian point. METHODS The 'on-off' experimental design was ...

Purpose Acupuncture has gained popularity since the National Institutes of Health 1997 Consensus Statement concluded that acupuncture is an effective anti-emetic for adult postoperative and chemotherapy-induced nausea and vomiting. The most commonly used acupuncture point to control nausea and vomiting is the Pericardium 6 (P6), or Neiguan point. Some evidence suggests that the anti-emetic effe...

Acupuncture can be an effective treatment for chronic anxiety disorders. The purpose of this study was to assess the effectiveness of acupuncture in reducing anxiety in a volunteer population. If found effective, this modality could be introduced as a treatment of anxiety before surgery. Adult volunteers (n = 55), were randomized to three treatment groups: a) Shenmen group--bilateral auricular ...

This short review article presents a current overview of existing publications and scientific results regarding liquid (ear) acupuncture. The injection of liquids into defined acupuncture points of the ear is not a method commonly used in the Western world. The term liquid acupuncture has different definitions, which makes understanding each definition and differentiating one from the other dif...

Although acupuncture is effective in the treatment of several clinical conditions, its specificity has been questioned. We studied the effects of needle stimulation applied to 'ear-specific' acupuncture point GB43 on activations in primary auditory cortex using functional magnetic resonance imaging in comparison with sham acupuncture. Twenty healthy volunteers participated in this cross-over in...

Therapeutic benefits of acupuncture for chronic pain patients have been clearly identified in recent clinical trials. Underlying mechanisms of acupuncture action mediated by endogenous opioids have been well demonstrated. The existence of pain inhibitory systems in the central nervous system has also been clarified and acupuncture seems to be a potent stimulus for activating the analgesic syste...

The topographic structures of acupuncture points were investigated by using the synchrotron radiation based Dark Field Image (DFI) method. Four following acupuncture points were studied: Sanyinjiao, Neiguan, Zusanli and Tianshu. We have found that at acupuncture point regions there exists the accumulation of micro-vessels. The images taken in the surrounding tissue out of the acupuncture points...

Location-dependent skin surface's partial nitric oxide pressure (pNO) is studied using highly sensitive amperometric NO microsensor with a small sensing area (diameter  = 76 μm). The pNO level of LI4 (Hegu) acupuncture point is measured and compared with the pNO level of nonacupuncture point. In addition, the mapping of pNO is carried out over the left wrist skin area one- as well as two-dimens...

OBJECTIVE To explore the effect of acupuncture at HT7 on heart rate variability (HRV) in healthy volunteers. METHODS 120 subjects were divided into four groups using a random number table. The following groups of acupuncture interventions were used: HT7 verum acupuncture; HT7 non-penetrating sham acupuncture; acupuncture at a sham point; and no acupuncture. HRV was recorded 10 min before, dur...
