“…[1][2][3][4][5][6][7][8][9][10] There are various views concerning the mechanism of this response, which is a general response that occurs when points on the arms, legs and trunk are stimulated. 1 One is that it occurs via the efferent pathway of the parasympathetic nerves, [1][2][3] while another is that it occurs via both the sympathetic and parasympathetic nerves. [4][5][6][7][8] Also, Nishijo et al report that light stimulation which is applied while a seated subject is exhaling mostly inactivates the parasympathetic nerves, 6 suggesting that posture is a major influence.…”

We investigated the difference in transient heart rate reduction associated with brief acupuncture in 20 healthy subjects at rest in a supine and in a sitting position. After the subjects had been at rest for about 20 minutes, acupuncture needling using the sparrow-pecking method, in which the needle is moved vertically lifting and thrusting, was performed for one minute at the Shousanli point on the right forearm (LI10). The procedure was carried out with the subjects in a supine position and in a sitting position. The position for stimulation of each subject, either supine or sitting, was selected at random, and on different days. The results showed that the average heart rate reduction associated with stimulation in supine subjects was 3.6±0.19 (mean ± standard error {SE}) beats per minute (bpm), while that for sitting subjects was about 7.0±1.07 (mean ± SE) bpm, indicating that stimulation reduces heart rate to a greater degree in subjects who are sitting (p<0.05, Mann-Whitney test). These results would be consistent with a mechanism involving reduced sympathetic drive to the heart, as sympathetic nerve activity has more influence on the heart rate in the sitting than in the supine position.

“…Our results indicated that the moxa group increased and maintained the value of EGG at the level of 3.0 -3.1 cpm (Figure 4). It is reported that the electrical activity of the normal human consists in regular pacesetter potential (frequency 0.05 Hz = 3.0 cpm) [4] and that amplitude and velocity of this activity increased as it approach the pylorus [15]. Thus the moxa stimulation increased gastric potential as well as acupuncture-like stimulation did.…”

“…Our study indicated that HR decreased after the moxa stimulation on ST36 ( Figure 5). Researchers reported that acupuncture-like stimulation to the leg decreased HR via polymodal receptors (PMR)s [15]- [19]. PMRs are characterized by activation from a wide variety of stimulations since the skin is exposed to various forms of stimulations from the external environment and they are widely distributed over the skin as well as in the somatic and visceral deep tissues.…”

The moxa therapy is a popular traditional hyperthermia therapy in East Asia. The moxa is made from dried mugwort (Artemisiaargyi). The moxa is usually put on a meridian point and then is burnt on to obtain a hyperthermic stimulation to the skin. However, very few researches have been studied in the effects and mechanism of the moxa therapy. Therefore, in this study, we gave the moxa stimulation to healthy subjects. In the moxa group, the moxa was lit on the ST36 (Zusanli: an acupuncture point in anterior tibialis of the leg) for 5 minutes. Their responses were traced with electrogastrogram (EGG) and assessed the change of gastric function. At the same time, their heart rate (HR) was recorded and observed to study the mechanism of moxa treatment. And then their results were compared with those of the control group. After the moxa stimulation, EGG showed significant increase and stayed 3.0 -3.1 cpm while HR prominently decreased. On the other hand, the control group did not indicate such results. Those results are common to the response of acupuncture-like stimulation by the reflex arc which consists of receptor, sensory neuron, central nervous system, motor neuron and effector. It may be explained as below: the elements of the acupuncture-like stimulation and the moxa are pain and hyperthermia respectively and they both are received by polymodal receptors. Thus the moxa stimulation applied on ST36 may be effective to enhance stomach function.

“…However, denervation caused by cutting the sciatic nerve, 9 destruction of the thin sensory nerves caused by capsaicin 7 and topical application of hCGRP [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27] (a CGRP receptor antagonist) 7 did not completely suppress the MA-induced increase in MBF, suggesting that other vasodilators contribute to this effect. A recent report showed that application of MA using the rotating needle technique locally raised the extracellular concentration of ATP, ADP, AMP or adenosine in mice 3 and humans.…”

Objective To investigate the contributions of nitric oxide (NO) and prostaglandins (PGs) to the increase in local muscle blood flow (MBF) observed following manual acupuncture (MA). Methods Male Sprague-Dawley rats (n=112; 250-310 g) were injected intraperitoneally with a non-selective NO synthase inhibitor (NG-nitro-Larginine methyl ester hydrochloride: L-NAME; 10, 50 or 500 mg/kg), a non-selective cyclooxygenase inhibitor (indomethacin; 10, 50 or 500 mg/kg), a combination of L-NAME and indomethacin (500 mg/kg each) or saline only under urethane anaesthesia (1.2 g/kg). We used the sparrow pecking technique for 1 min with a stainless steel acupuncture needle (0.20×30 mm) as the acupuncture stimulation method. The stimulus point was on the right tibialis anterior muscle. 51Chromium-labelled microspheres were used for MBF measurement. Results MA increased MBF in the saline-injected group ( p<0.001). This increase was partially inhibited by L-NAME in a dose-dependent manner ( p>0.05, p<0.05 and p<0.001 for 10, 50 and 500 mg/kg, respectively). On the other hand, indomethacin did not suppress the increase ( p>0.05 each for 10, 50 and 500 mg/kg). No significant difference was observed between the inhibitory effects of combined administration of L-NAME and indomethacin and single administration of L-NAME ( p>0.05). Conclusions These results suggest that NO is a major factor in the MA-induced increase in MBF, while PGs do not contribute significantly to this increase. As complete inhibition was not achieved by administration of L-NAME±indomethacin, it appears that non-NO and non-PG vasodilators are additionally involved.
