Objectives : The aim of this study is to investigate the effect of Shinmun-acupuncture stimulation on the relationship of change in electrocardiopgraphy (ECG). Methods : For this purpose, 11 healthy volunteers were acupunctured at Shinmun acupoint using the reinforcing or reducing by inserting the needle in the same direction as the channel runs or in the opposite direction (迎隨補瀉). Then, we measured and observed the change of standard leads I, II and III in ECG. Results : In lead I , acupuncture treated groups were increased the activity of PR interval and PR segment compared to the control group. In lead II, during the acupuncture treated group by inserting the needle in the opposite direction as the channel runs was increased the activity of T wave duration, and after the acupuncture group by inserting the needle in the same direction as the channel runs was increased the activity of PR interval. In lead III, acupuncture treated groups were increased the activity of ST duration, PR interval and QT interval. Conclusions : These results suggested that Shinmun acupuncture stimulation plays an important role on the activities of ECG.

Objectives : This study is to investigate stimulation effects of acupoints at differential meridian along arm and leg on the physiological phenomenon of heartbeats. Methods : 8 subjects were participated in this study. The experiments were performed in Resting session(Rs), Insertion session(Is), Stimulation session1(Ss1), Stimulation session2(Ss2), Stimulation session3(Ss3) sequence. Time of each session and the interval between each session was 30 seconds all. Acupuncture was performed manually on PC3 or LR8 at random with a two-day interval. stand deviation of N-N interval(SDNN) was measured for each session. Results : At PC3, SDNN increased in Ss1, Ss2, and Ss3 compared to Rs but at LR8, there was little change between Ss1, Ss2, Ss3 and Rs. Post-hoc analysis revealed that mean value of SDNN significantly increased in Ss1 compared with Baseline at PC3, while there was little change at LR8. When LR8 and PC3 were compared at each time point, there was a significant difference only in Ss1. Conclusions : Our results indicate that there is a correlation between specific physiological functions and acupoints.

We examined the radioprotection effects of acupoint (acupuncture point) stimulation during organogenesis stages of ICR mice. Pregnant mice received 1.5 Gy whole body X-irradiation on day 8 of gestation, which is the early stage of organogenesis. The embryonic death rate and teratogenesis rate by radiation were examined. Electroacupuncture to the leg acupoints and/ or transcutaneous stimulation to the back acupoints on the pregnant mice showed no protective effect against irradiation on embryonic or fetal death rate. On the contrary, the strong stimulation resulted in increase in the mortality after irradiation rather than protection. However acupoint stimulation to the pregnant mice never showed harmful effects by itself on embryos. It tended to reduce the skeletal malformations induced by X-ray irradiation. We suspect that acupoint stimulation removed the cells injured by irradiation during embryonic development, resulting in an increase in embryonic death rate and reduction in skeletal anomalies.

Objective : Recent studies Suggested that there is a strong correlation between acupuncture stimulation and its related cortical activation. Anther study showed that either positive or negative BOLD effects could be observed depending on anatomical structure in acupuncture. Material and Methods : 1) Subjects and paradigms : Two separate stimulation paradigms were performed on five healthy (aged 22-23 yrs) in this study. First, the paradigm of acupuncture stimulation was that the acupuncture needle was inserted in acupoints KI6(照海), which is located in lateral side of the foot and then continuously twisted(補瀉를 除外한 捻轉法) for 70 seconds for 10 cycles of activation. During rest period (70 seconds), the needle was completed removed from acupoint. Total 60 cycles were performed and 10 images were obtained per cycle. Second, non-acupoint was randomly selected and the same paradigm was performed as acupoint stimulation. The stimulation protocol comprised 10 cycles of alternating activation and rest (10 images per cycle). Total 60 cycles were performed and each cycle take about 1.5 sec for motor task. Subjects take an at least 15 minutes break before starting anther paradigm. Conclusion : In this study, I investigated a new acupoint KI6(照海) which was known as motor - related acupoint and obtained an evidence that the stimulation of KI6(照海) resulted in negative BOLD response to stimulation.

A 30-year-old woman with Grade III hemorrhoid complained of excruciating pain that continued for several hours, especially with defecation. She was not able to frequent the clinic due to COVID-19 shutdowns, therefore additional treatment using acupoint electrical stimulation (AES) was self-administered. She administered AES bilaterally on BL57 and LR10 for fifteen minutes before each defecation as a preconditioning treatment. She assessed her pain using a Numerical Rating Scale (NRS) during defecation, and 3 hours later. The patient initially complained of pain rating 9 on the NRS. After the first session of AES, the pain dropped to 5. On one-month follow-up, the pain was at 3 and the patient was able to terminate all treatment. Self-administered AES preconditioning at BL57 and LR10 can be used to reduce extreme cases of hemorrhoid pain.

Objectives : The objectives of this study is to compare the effects of electroacupuncture(EA), warm needling(WN) and Radio Frequency warm needling(RFWN) stimulations on the acupoints at the artificially damaged ankles of Sprague-Dawley rats, which could be classified as the Grade 3. Methods : The foot weight bearing force ratio(FWBFR) of ankle sprain was measured first at 24 hours after without any other stimulations. Pain Recovery Index(PRI) represents the analgesic level, and modified Pain Recovery Index(mPRI) shows the accumulated recovery level. PRI was measured at 2 hours after each stimulus on GB34, GB39 and GB42, and mPRI was during 7 days. Results : EA stimulation of GB34 and GB39 acupoint in grade 3 ankle sprain showed a marked analgesic and recovery effect. RFWN of GB42 exhibited significant analgesic and pain recovery effect. RFWN of GB34 resulted in pain recovery effect but not analgesic effects, and RFWN of GB39 resulted in analgesic effect 2 hours after but not pain recovery. However, WN did not affect the pain recovery among three acupoints at all. Conclusions : In the Grade 3 ankle sprain model, the difference of analgesic effects were explained by the acupoints and the stimulation methods according to the accumulated recovery effects during 7 days. It is insufficient to determine that a certain acupoint has a specific analgesic effect depending on the stimulation method by the results of this study. Therefore, the effects of each stimulation on the acupoints in any other meridians at the sprained ankle should be compared and analyzed.

Objectives : The purpose of this study was to investigate the Effect of Acupuncture Chok-samni(ST36) on Skin temperature(ST), Galvanic skin response(GSR) and Heart rate(HR) in humans. ST36 is used in uneasiness, high fever, stroke, paralysis on oriental medicine. Methods : Subjects were 18 healthy oriental medical students volunteers(15male, 3female, mean age-28). Under sequence of ST36 acupuncture, the first group was observed ST, the second group was observed GSR and the third group was observed HR. Skin temperature was measured on Haegye acupoint(ST41) before and after acupuncture stimulation. Each test took 15minutes. This test was performed twice in order to increase the statistical authenticity. Results : Our result indicates that acupuncture stimulation of ST36 statistically decreased skin temperature on ST41. Also statistically decreased in HR. The change of GSR after ST36 acupuncture was decreased, but there is no statistical. Conclusions : These results suggested that acupuncture stimulation of ST 36 has effect on ST and HR in human body, and may be used by treatment as control the nerve system.

The purpose of this study was to investigate the effect of pulsed magnetic field (PMF) and low frequency low level laser (LFLLL) stimuli on acupoint LI4 (Hegu) using photoplethysmography (PPG). Our PMF system was designed to generate maximum intensity of 0.20 T at a transition time of 0.16 ms, with pulse intervals of 1 Hz. The diode laser with wavelength of 650 nm and power of 5 mW was also employed. It was observed the change of the pulsating blood volume through measuring PPG signals from both hands. These results imply that stimulating acupoint LI4 with PMF and LFLLL improves the circulation of peripheral vascular system. In particular, PMF stimulation brings a big improvement of the blood flow even with short term stimulation of 3-4 minutes compared to LFLLL stimulus.

The aim of this study is to learn the effects of ST36 ST44 and ST25 ST36 electroacupuncture stimulation on high fat diet-induced obese mouse. The control group was provided with high fat diet without electroacupuncture stimulation, while the experimental group received a electroacupuncture stimulation on ST36 ST44 and ST25 ST36 with three frequencies (10Hz, 100Hz, 200Hz) for 5 times a week during five week periods with the high fat diet. We investigated the body weight, weight gain, and food intake. After the electroacupuncture stimulation, a significant inhibition of increase in weight was found in the experimental group compared with the high fat diet group. But there were no significant differences made by the change of acupoint combinations and frequencies. After the electroacupuncture stimulation, no significant change was found in the food intakes, but the weight gain a week was decreased compared with the high fat diet group. Electroacupuncture stimulation may be effective in treatments of obesity to high fat diet, But no significant difference was found between three frequencies.

Purpose: The aim of this study is to find the location of acupoints that are effective for increasing parasympathetic nervous system(PNS) activity among acupoints used to relieve symptoms such as dizziness and nausea. Materials and Methods: Twenty healthy adult men participated in this experiment. Transcutaneous electrical nerve stimulation(TENS) was applied to P6(Neiguan), ST36(Zusanli) and BL20(Pishu) for 30 minutes. For 5 minutes before and after stimulation, Electrocardiogram(ECG), Electrodermal activity(EDA), Respiration, and Skin temperature(SKT) were measured using biosignalsplux Professional(biosignalsplux; Portugal). Paired t-test was performed for the results before and after stimulation, and a one-way ANOVA test between stimulations was performed for the rate of change before and after stimulation. Results: When each acupoint was stimulated with TENS, it was found that the PNS was generally activated. In addition, when considering the change in biosignals after stimulation, the participants stimulated with P6 showed the most consistent results. Conclusion: As a result of stimulating each acupoint, it was found that stimulating P6 can effectively increase PNS activity. These results indicate that methods of stimulating P6 may be most effective in alleviating symptoms of motion sickness.
