수궐음심포경을 전기 자극한 후 두 자극점내 경혈점에서 온도강하가 이루어짐으로 보아 수궐음심포경에 대한 자극은 열의 발산을 활발하게 한다고 생각되어진다. 50Hz에서 노궁 (PC8)과 극문 (PC4)사이 온도차이가 100Hz와 150Hz의 자극에 비하여 적게 나타남을 확인할 수 있었다. 따라서, 인체의 열에너지 발산정도가 주어지는 자극세기에 비례한다고 생각되어진다.

Crystal A and B were isolated from L. pseudo-leave Nakai and their pharmacological action was observed. Crystal A, in dose of 5 * $10^{-4}$ - 5 * $10^{-5}g/ml$, stimulated excised frog heat but at 2.5 * $10^{-6}$ - 0.5 * $10^{-5}g/ml$ of crystal B, depressant effect was observed. Mild stimulation of rhythmicity of exercised rabbit intestine was produced by 1 * $10^{-4}$ g/ml of crystal A and 2 * $10^{-4}g/ml$ of crystal B. Marked depression of tone was produced by 2 * $10^{-4}g/ml$ of crystal A, antagonizing by pilocarpine. Crystal B(4 * $10^{-4}gm/l)produced$ mild stimulation, followed by depression of tone. No curare-like action on excised frog abdominal muscle was elicited with both substances.

The use of Duplex stainless steel as a thermo-implant categorizes into two clinical applications: hyperthermia and thermal ablation or destruction. The goal of hyperthermia is to destroy the heat-sensitive abnormal cells and minimize normal cell death maintaining heat between $42^{\circ}C$ and $46^{\circ}C$. Thermal ablation takes place when the local tissue temperature increases greater than $46^{\circ}C$. This elevated temperature denatures protein irreversibly resulting cellular death. The author introduced several thermo-implants such as thermo-rod, thermo-stent, thermo-coil and thermoacupuncture-needle. Those thermo-implants are made of duplex stainless steel which can produce regulated heat by itself within an induction magnetic field. Thermal ablation characteristics of the thermo-rod on tumor hyperthermia depend on configurations of the thermo-rods and the magnitude of the induction magnetic strength. The exothermic properties of the thermo-implants can be characterized using the calorimetric test and the heat affected zone(HAZ) analyses in vitro. Thermal radiation studies using thermo-coils and thermo-stents show the capability of the occlusion of animal blood vessels and inhibiting the proliferation of the abnormal smooth muscle cell growth and inflammatory cell reactions maintaining the heat between $42^{\circ}C$ and $46^{\circ}C$ minimizing a normal cell death in the study on external iliac artery of the New Zealand White (NZW) rabbit. Thermal stimulation study using thermo-acupuncture needles suggests the potential applications of the automated acupunctural therapies.

Purpose: The purpose of this study was to investigate influence of superficial heat and deep heat for lumbo-sacral segment on H-reflex. Methods: Subjects of this research were 12 normal men and women (6 men and 6 women) and they were assigned to superficial heat group (6) and deep heat group (6). Heat treatment was applied between Th12-L2 by placing them at prone posture. superficial heat was applied for 20 min at 30 cm height with infrared lamp. Deep heat was applied for 20 mm at 5 cm height with 100 watt of microwave diathermy. H-reflex used diagnostic electromyography, active electrode was placed at muscle belly of medial gastrocnemius muscle at prone posture and electrical stimulation was given to posterior tibial nerve. Measurement was made before and after experiment and 10 min. and 20 min. after experiment. All data were analyzed with window 12.0 program, comparison of differences among measured items of groups according to repeated measurement was made with repeated measures ANOVA and significance level a was 0.05. Results: M latency at latency analysis showed little changes at two groups. H latency was reduced a little immediately after experiment and recovered to original state, there was significant difference. In analysis of amplitude, Mmax amplitude showed rise a little immediately after.

Objectives : The present study was conducted to evaluate the analgesic effects of automatically controlled heating acupuncture(ACHA) using 2 different pain models(acute pain and neuropathic pain) and 2 different stimulation conditions (heating $41.5^{\cdot}C$ and heating $44.5^{\cdot}C$) in Sprague-Dawley rats. Methods : Tail flick latency(TFL) to a noxious radiant heat stimulus in lightly anesthetized rats was measured before and after ACHA stimulation for 5-min at the Zusanli(ST36) acupoint. For the neuropathic surgery, the right superior caudal trunk was resected at the level between S1 and S2 spinal nerves innervating the tail. Two weeks after the nerve injury, ACHA stimulation($41.5^{\cdot}C$ or $44.5^{\cdot}C$) was delivered to Zusanli(ST36) for 5 min. The behavioral signs of warm allodynia were evaluated by the tail immersion test (i.e. immersing the tail in warm $water(40^{\cdot}C)$ and measuring the latency to an abrupt tail movement) before and after the ACHA stimulation. Results : In the TFL test, ACHA stimulations under both the conditions above produced more potent analgesic effects than plain acupuncture(PA, acupuncture needle insertion only) and control(no treatment). In the tail immersion test, ACHA stimulations under all of the conditions had markedly relieved the warm allodynia signs. Conclusion : Automatically controlled heating acupul1cture produced analgesic effecs in acute and neuropathic pains.

Objectives : Proper acupuncture stimulation is associated with a characteristic set of sensation usually referred to as 'De-Qi'. In order to develop the appropriate sham acupuncture, various sensations to each stimulation should be considered through analysis of the profiles of acupuncture sensation. It was therefore investigated to compare the acupuncture sensation scale (ASS) of two types of sham acupuncture to that of the real acupuncture. Methods : Ninety-four participants (mean age 26.4, range 26-49) were asked to complete five point-Likert scale ASS developed by Vincent et al. after real or two-kinds of sham acupuncture stimulation: blunted tip sham acupuncture (BT) and round tip sham acupuncture (RT). Needling was done at LI4 acupoint on non-dominant hand and stimulated for 30 seconds with real or two-kinds of sham needle. Finger withdrawal latency (FWL) of each group was also measured to evaluate the pain sensitivity to noxious heat stimuli. Results : BT acupuncture significantly less produced penetrating, numb, intense, hurting, pulling, shock, tingling, throbbing sensation than real acupuncture stimulation. RT acupuncture significantly less produced penetrating, burning, electric, numb, intense, hurting, pulling, aching, shasharp, shock, stinging, tingling, throbbing sensation than real acupuncture. Each group did not demonstrate the differences of pain sensitivity to noxious stimuli. Conclusions : These results indicated that types of tip of acupuncture produced different kinds of acupuncture sensation. Our finding provides a general information of sensations to two kinds of sham acupuncture for development of ideal placebo sham needle.

Objectives : Moxibustion has been become very useful tool to prevent and treat various diseases with acupuncture in oriental medicine. Expecially, moxibustion combining the heat stimulation and chemical stimulation of Artemisiae Argyi has a non-invasive characteristics comparing to the other therapeutic tools. However, because the moxibustion makes the patient's skin be burn by the combustible feature of moxibustion, most of people have been scared of being scald. Methods : In this study, we have developed new non-combustible moxibustion tools in collaboration with company (Hana Medical, co. and ICURE, co.) and tested the efficacy through effects of moxibustion of Cheon-chu $(ST_{25})$ on the abdominal thermography of health subject. The non-combustible moxibustion has main characteristics of controlled heating to inhibit being scald and heat stimulation lasting over 1 hrs. Also, to induce the chemical stimulation, the bottom contacting with skin was coated by the extract of artemisiae argyi. The volunteers who participating in this study had taken rest for 20 - 30 mins in room temperature $(23-25^{\circ}C)$ before the examination and informed them what to prohibit smoking, drinking and administration of drug for the previous day The thermography of abdomen including a below part of the chest was taken using Infra-Red Imaging System (IR 2000, MEDI-CORE Co., Korea) by time interval of 15 minutes. Results : The results showed that moxibustion of Cheon-chu $(ST_{25})$ had more potencies of changes on all the ROIs of abdominal thermography than those of control group. Also, it was observed that the quantities of thermal changes following moxibustion of Cheon-chu $(ST_{25})$ been increased significantly comparing that of control group at all the ROIs (region of interest). Observed the thermography classified by ROI, however, moxibustion of Cheon-chu $(ST_{25})$ could modulate ipsilateral specific areas concerning to the abdominal pathway of Stomach Meridian. Conclusion : These results suggest that new non-combustible moxibusion has some similarity as like as the conventional moxibustion and moxibustion of Cheon-chu $(ST_{25})$ may modulate thermal changes of abdominal areas.

In order to get the basic data for the study of the heat stimulation of burning moxa, the pattern of combustion temperature, which is one of the important factors of thermal characteristics, was measured by density of cone moxa along the time procedure. The following results have been obtained 1) The pattern of combustion temperature by moxa burning was classified into input period which means the infiltration of heat into the area and output period which means the radiation of heat from the area. The input period consists of preheating and heating periods, while the output period consists of heat retaining and cooling periods. 2) The pattern of combustion temperature showed the same type or curve, which was not influenced by the moxa weight. However, Its pattern gradient are varied by density. It is considered that the pattern of combution temperature is primarily influenced by the rate of combustion temperature, gradient temperature and duration of combustion.
