This study was performed from March to September 1997 on 95 healthy students to observe the effects of acupuncture at Hap-kok (LI4) according to the meridian and qi-xue(氣血) phenomenon of oriental medicine's theory. Skin temperature on the Hap-kok (LI4) and Chun-Choo (ST25) were measured by D. 1. T. I. (Digital Infrared Thermograph Imaging) before acupuncture stimulation and 1min, 10 min after acupuncture stimulation. 1. In healthy students, the left and right mean temperature of LI4 and ST25 was $29.04\;^{\circ}C,\;29.12\;^{\cir}C\;and\;30.29\;^{\circ}C,\;30.22\;^{\circ}C$ respectively. 2. In control group, the time dependent changes for 10 min of LI4 and ST25 were $-0.32\;^{\circ}C,\;-0.36\;^{\circ}C\;and\;-0.5\;^{\circ}C,\;-0.46\;^{\circ}C$ respectively, however, the thermal differences of both sides LI4 and ST25 were not changed for 10 min. 3. In acupuncture stimulation of both sides LI4, the time dependent changes of ST25 were $-0.13\;^{\circ}C,\;-0.06\;^{\circ}C$, and the thermal differences of both sides ST25 were reduced, but not changed significantly. In acupuncture stimulation of right side LI4, the time dependent changes of LI4 were $-0.1\;^{\circ}C,\;-0.32\;^{\circ}C$ respectively, and the thermal differences of both sides LI4 were increased more than control, but not significantly. Also, that of ST25 were changed by $-0.69\;^{\circ}C,\;-0.63\;^{\circ}C$ respectively, but not significantly. 4. In acupuncture stimulation group, it was classified following the thermal differences of both sides LI4 and ST25, and the effects of acupuncture were observed by changes of classification. The acupuncture of both sides LI4 results in temperature of the left side ST25 to be high after acupuncture. The acupuncture of right side LI4 results in increased ratio of the left side higher than right LI4. The above results indicates that D. I. T. I. was a useful method to observe follow-up the effects and changes by acupuncture stimulation on objective evaluation of phenomenon for the meridian system. Thus, acupuncture on LI4 affects to thermal changes of ST25 and LI4, but exact examination of thermal changes on ST25 will have to be.

Objectives : This study was aimed to show the effect of electroacupuncture combined with magnetic acupuncture on abdominal obesity without patient dieting, exercise or use of herbal medication. Methods : Women over 85 cm in waist circumference were treated with electroacupuncture combined with magnetic acupuncture. Acupuncture points were located at the abdomen ($CV_{12}$, $CV_6$, $ST_{25}$, $ST_{21}$, $SP_{15}$, $SP_{14}$), extremities ($LI_4$, $LI_{11}$, $ST_{36}$, $ST_{44}$) and were stimulated 30 minutes with 2.1~3 Gaus, 500 Hz, tolerable strength. The Interference wave forms were by Whata 153 (Medi Lab, Korea). Two or three treatment sessions per week (five or ten sessions in total) were done. Before treatment, and after the last treatment, we measured waist circumference, hip circumference, waist hip ratio, thickness of abdominal subcutaneous fat, body weight, body mass index, body fat ratio, visceral fat area, free fat mass, body fat mass and skeletal muscle mass. We also measured the subcutaneous temperature of the abdomen($CV_{12}$, $ST_{25}(Rt)$, $ST_{25}(Lt)$, $CV_6$) by using digital infrared thermal imaging(DITI). Results : In this study, significant reductions were shown in waist circumference, hip circumference, thickness of abdominal subcutaneous fat, body weight, body mass index, body fat ratio and body fat mass. There were no significant differences in waist hip ratio, free fat mass or skeletal muscle mass. There were also significant increases of the subcutaneous temperature on $CV_{12}$, $ST_{25}(Rt)$, $ST_{25}(Lt)$. Conclusions : From the above results, electroacupuncture combined with magnetic acupuncture might be an effective treatment for abdominal obesity.

Objectives : This study was to investigate the regulatory effect of electro-acupuncture on Jogsamni ($ST_{36}$) in bradygastric condition or gastroparesis which is a neuropathic complication of type 2 diabetes mellitus(T2DM), assessed using 4-channel electrogastrography (EGG). Methods : It was a case series study. Each patient was given electro-acupuncture(EA) one point, Jogsamni($ST_{36}$) or Gyeonu($LI_{15}$) bilaterally for thirty minutes with 2Hz bipolar square wave frequency and moderate intensity of stimulation. With attaching electrodes around stomach region throughout pre-acupuncture, acupuncture, and post-acupuncture session, these parameters were produced; percent rate of bradygastria power compared to sum of power in all kind of gastric rhythm(% bradygastria), dominant frequency(DF) and dominant power(DP). Parameter was analysed per each channel's variable change from pre-acupuncture session by paired t-test. Results : There was statistically significant decrease in % bradygastria parameters on one of the $ST_{36}$ treated patients from pre-acupuncture session and to post-acupuncture session(P=0.015, P=0.008 respectively). A marginal significant decrease of DP was shown in the other $ST_{36}$ treated patient from pre-acupuncture session through post-acupuncture session(P=0.049). Combined data of two $ST_{36}$ Treated patients showed that there was significant decrease of %bradygastria from pre-acupuncture session to acupuncture session(P=0.020), and was decrease of DP from pre-acupuncture session to post- acupuncture session(P=0.020). Conclusions : EA at $ST_{36}$ resulted in statistically significant decrease in %bradygastria and DP for dysrhythmic condition in T2DM gastroparesis patients. Considering this limited results, further study will be needed to elucidate the effect of multiple-acupuncture on gastric myoelectrical activities.
