Many patients who receive general acupuncture treatment have many complaints concerning their autonomic nervous systems. Applying CMI and CMI type classification (Abe method-a variation of CMI) to 100 new patients who came to our clinic last year, we found vegetative dystonia in half of them. Upon this finding, the following examinations were carried out by means of an function test of autonomic nervous system developed by Kageyama et al.: the coefficient of variation (CV) of R-R interval in ECG obtained through the function test is regarded as an expression of vagal function.
(1) Using this test, the participation of the autonomic nervous system in the condition of those patients who visited our clinic was examined.
(2) Effects of acupuncture treatment on the autonomic nervous system were examined.
(3) Acupuncture stimulation was separately applied to S36 (Zusanli), P4 (Ximen) and Liv3 (Taichong) to examine the influence of the acupuncture point location on the CV obtained through the test.
Results:
(1) 15 new patients (25%-comparatively high rate) showed low CV (less than 2%) of R-R interval in ECG.
(2) In some cases, acupuncture treatment caused an increase in CV.
(3) Acupuncture caused pulse infrequens: R-R interval showed a tendency toward prolongation during the in situ needle technique and after withdrawing the needle on each of the three points (S36, P4 and Liv3). CV increased after withdrawing the needle on either S36 or Liv3 and shortly after needle insertion and after withdrawing the needle on P4.
These result suggest that many patients who receive acupuncture treatment have additional disorder in parasympathetic nervous system which can be improved through acupuncture.

Comparing the effects of low energy laser and acupuncture was conducted in 14 patients with gonarthrosis. Effectiveness on the pain on going up or down stairs, range of motion (ROM) of knee joint and tenderness were examined. After acupuncture treatment, the pain on going up or down stairs, and ROM of knee joint were significantly improved. Laser therapy showed the same significant effects both on the pain on going up or down stairs and ROM of knee joint. In addition, laser therapy showed a significant effect on tenderness. In the statistical evaluation, no remarkable difference was shown between acupuncture therapy and laser therapy. Present data suggest that the laser therapy is as effective as acupuncture therapy in gonarthrosis.

Laser-Doppler velocimetry was used to evaluate the effects of acupuncture stimulation on peripheral circulation disturbance in patients with collagen disease, progressive systemic sclerosis (PSS) and systemic lupus erythematosus (SLE). The response to acupuncture stimulation to shou-san-li was recorded in 8 patients with PSS and 6 patients with SLE. The digital pitting scars and Raynaud's phenomenon were observed in all the patients. The mean of laser-Doppler flow values in fingertips at room temperature 23°C was 4.83 (V) in normals (n=11), 2.82 (V) in patients (n=14). Patient group showed significantly lower values than normals (p<0.01). Ten minutes after acupuncture stimulation to shou-san-li, the flow values increased in 7, and decreased in 1 out of 13 patients (p<0.05). In normals no significant change was observed after the same stimulation. Present data suggest that the acupuncture therapy to the patients with PSS or SLE who suffered from peripheral circulation disturbance is effective.

Laser-Doppler velocimetry (LDV) was used to evaluate the effects of low energy laser irradiation on peripheral circulation disturbance in patients with collagen diseases, progressive systemic sclerosis (PSS) and systemic lupus erythematosus (SLE).
Using a commercially available LDV flometer (Periflux, Perimed KB, Sweden), the response to laser irradiation at the acupuncture points of Tian zhu, Feng chi, Jian jing, Shou san li, Jing qu, He gu, Stellate ganglion, was recorded in 4 patients with PSS and 6 with SLE. The digital pitting scars and Raynaud's phenomenon were observed in all the patients. The low energy of 10mW laser was irradiated for 1 minute at each acupuncture points, and LDV flow values ware recorded in fingertips at room temperature 25±0.5°C. Ten minutes after the laser irradiation, the LDV flow values increased significantly (p<0.5).
Present data suggest that the low energy laser irradiation to patients with PSS or SLE who suffered from circulation disturbance is effective.
