ABSTRACT
The effect of acupuncture on the autonomic nervous system was analyzed by simultaneous measurement of sympathetic skin response (SSR), sympathetic flow response (SFR) and Palmer emotional sweating evoked with electric stimuli to the forehead at random interval and intensity. The mutual relation of measurements by those parameters was examined electrophysiologically.<BR>The subjects were ten healthy male volunteers. SSR at the left palm and SFR at the fingertip of the left forefinger were measured using laser doppler flowmetry, and emotional sweating at teh right palm was measured with the ventilated capsule method (hydrography). The measurements were performed in two sessions, with and without acupuncture stimulation that was given at L14 with the technique of sparrow picking (1Hz) for 1 minute and retaining the needle for 10 minutes. The amplitude of SSR, the reduction rate of SFR, and the sweat rate were measured before and after acupuncture stimulation, while those were measured before and after resting in the other session as a control study. As a result, habituation in each response was not seen and the correlation coefficient in each index was low, while SSR and Palmar sweating were inhibited significantly in the stimulation group only, and SFR was inhibited in both groups.<BR>These results suggested that acupuncture stimulation might inhibit the activity of the skin sympathetic nerve system.
ABSTRACT
To investigate the effect of acupuncture treatment combined with extreme infra-red rays radiation, we measured both skin surface and deep temperature at the stimulated area and peripheral site. The subjects were seven healthy volunteers with no problems involving the skin or autonomic nervous system. Acupuncture stimulation was performed on the Subject's back in combination with extreme infra-red rays radiation. The skin surface and deep temperature were measured at both the stimulated area and peripheral site (sole of the foot) using a thermistor temperature sensor and deep tissue thermometer during stimulation. We also measured temperature at those sites during extreme infrared rays radiation without acupuncture stimulation as a control study. Acupuncture stimulation combined with extreme infra-red rays radiation on the subject's back increases both surface and deep temperature at both the stimulated area and the peripheral site (sole of the foot), while the radiation alone had no effect on the temperature at the peripheral site. We suggested that acupuncture treatment combined with extreme infra-red rays radiation was useful to increase skin surface and deep temperature not only at the stimulated area but also at the peripheral site.
ABSTRACT
We studied the effects of transcutaneous electrical nerve stimulation (TENS) of Baxie on local cold tolerance as an index of cold induced vasodilatation (CIVD). The subjects consisted of 22 healthy adult volunteers.<br>The skin temperature and skin blood flow in the middle finger were measured simultaneously before, during, and after immersing the finger in cold water. TENS at 1Hz with 100-V intensity was applied for 5 minutes before immersion of the finger.<br>Experiments were conducted with no stimulation and with TENS on the same subjects on different days.<br>The results revealed the following:<br>1. The minimum skin temperature and minimum skin blood flow during immersion of the finger in cold water were higher in the TENS group than in the control (no stimulation) group.<br>2. The maximum skin temperature, mean skin temperature, and increase and decrease of skin blood flow rate during immersion of the finger in cold water and in the rising phase of skin temperature were higher in the TENS group than in the control group.<br>3. The index of resistance to frostbite was higher in the TENS group than in the control group.<br>4. The number of fluctuations in skin temperature during immersion of the finger in cold water was significantly higher in the TENS group than in the control group.<br>5. The incidence of abnormal perception during immersion of the finger in cold water was lower in the TENS group than in the control group.<br>These results suggest that TENS enhances the local cold tolerance of fingers by suppressing SSA in the initial falling phase on skin temperature and increasing the motion of skin blood vessels in the rising phase of skin temperature.
ABSTRACT
We studied the effects of electro acupuncture stimulation of Baxie on local tolerance as an index of cold induced vasodilation (CIVD). The subjects consisted of 22 healthy adult volunteers. The skin temperature and skin blood flow in the middle finger were simultaneously examined before, during, and after immersion of the finger in cold water. Electroacupuncture stimulation at 1 Hz with a 66 to 100V intensity was performed for 5 minutes. Experiments of no stimulation and electroacupuncture stimulation were conducted on the same subject on different days.<br>The results revealed the following:<br>1. CIVD was caused by rapid increase of skin blood flow during immersion of the finger in cold water.<br>2. The minimum skin temperature, minimum skin blood flow, maximum skin blood flow, mean skin temperature in the rising phase of skin temperature, and the index of resistance to frostbite of the electroacupuncture stimulated group were higher than those of the unstilmulated group, and rates of skin temperature increase and decrease during immersion of the finger in cold water in the electroacupuncture stimulated group were significantly higher. These results show that electroacupuncture stimulation increases local cold tolerance in the finger.
ABSTRACT
Objective: Very few studies have been reported on the specific functions of individual meridians and acupuncture points. We examined the functional relations between “the gallbladder Meredian and gallbladder” using the gallbladder's form as an index, in older to identify the specific functions of individual meridians and acupuncture points.<br>Subjects and Methods: This study was made on five healthy male adult volunteers who fasted during the experiment day.<br>The gallbladder was selected as the target organ and its form was measured with an ultrasonic diagnostic apparatus (Toshiba SSA-90A). The images of the gallbladder form were taken at the pointwhen the major axis of the cross-sectional area of the gallbladder was maxium. The cross-sectional area of the gallbladder was measured with an image analyzer. The gallbladder form was measured 15 minutes after the subject had lied on his back. Images were taken at intervals of 2 to 5 minutes 10 minutes before stimulation and for 30 minutes during and after stimulation. Acupuncture stimulation was given at the points of C34. Dannang, G36, G37, G40, and G44 on the right side of the body. After getting the degi, 1 minute of sparrow picking needle technique and 1 minute of leaving needle technique were repeated three times.<br>Results: 1) Stimulation of the G34, G36, G37, and G44 gave no effects on the gallbladder form. 2) Stimulation of the Dannang (EX) produced contraction of the gallbladder. 3) Stimulation of the G40 produced distension of the gallbladder. From the above results, we found that there two types of acupuncture points; one causes contraction of the gallbladder, and the other, distension of the gallbladder. This suggests that individual acupuncture points have specific functions.
ABSTRACT
Objective:<br>There have been a few reports on the specificity of the meridians and Acupuncture-points. In order to identify the specific effects of the meridians and Acupuncture-points, the functional relations between “the gallbladder Meridian and gallbladder” were investigated using the gallbladder's form as an index.<br>Materials and Methods:<br>Ten healthy male adult volunteers participated in the experiments in fasting conditions. The target organ was the gallbladder, and its form was measured with the ultrasonic diagnostic apparatus (Toshiba SSA-90A). The images of the gallbladder form were taken at the point when the major long axis of the cross-section of the gallbladder reached the peak. The cross-sectional area of the gallbladder was measured with the image analyzer. The measurement of the gallbladder form was conducted after 15 minutes lying on the back, taking images for 10 minutes before stimulation, for 30 minutes during and after stimulation, every two to five minutes. The acupuncture stimulation was given at the points of G34, G36, G37, G40 and G44 on the right side of the body. After getting the deqi, 1 minute of sparrow pecking needle technique and 1 minute of leaving needle technique were conducted three times. The effect of the G40 under the egg yolk loading were also investigated.<br>Results:<br>1) The stimulation of the G34, G36, G37, and G44 showed no effects on the gallbladder form. 2) The stimulation of the G40 caused the distension of the gallbladder form. 3) The stimulation of the G40 showed the suppressive effect on the contraction of the gallbladder due to the load of egg yolk.<br>As described above, the results of this study showed that there is an acupuncture-point on the gallbladder meridian to cause the distension of the gallbladder specifically. It suggests the existence of the specificity of acupuncture-point.
