Objectives : This study was performed to investigate the effects of fixed-intensity and varied-intensity electroacupuncture on heart rate variability in healthy people with stress task. Methods : Forty healthy subjects were randomly assigned to either group A or group B or C. Group A received fixed-intensity electroacupuncture(F-EA) at $ST_{36}$ and $ST_{37}$. After 1 week wash out period to prevent overlapping residual effects, they received varied-intensity electroacupuncture(V-EA) in which the intensity was changed every two minutes based on individual heart rate variability at the same points. Group B received the treatments in reverse order. Group C received no intervention as a control group. Results : Control group showed a significant increase of LF and LF/HF during the 2nd working memory task, while both F-EA and V-EA did not. In addition, V-EA showed a significant increase of HF during 2nd rest while F-EA did not. Conclusions : These results suggest that F-EA and V-EA can inhibit sympathetic activation more than control group and that V-EA can enhance parasympathetic activation more than F-EA.

The aim of this study was to collect and analyze clinical studies on electro-acupuncture therapies of post-stroke dysphagia to suggest the methods of the study about electro-acupuncture therapy. In this study, electronic searches were performed with searching sites. Searched words such as '중풍', '뇌졸중', '연하장애', '전침', 'stroke', 'dysphagia', 'deglutition disorders', 'electro-acupuncture' were used as a single keyword or in combinations. Through searching, 27 studies were selected and analyzed. In comparison of results before and after electro-acupuncture treatment, there were statistically significant improvement in 26 studies by using assessment such as video fluoroscopy swallowing study, swallowing water function test. The study of electro-acupuncture treatment for post-stroke dysphagia needs to be standardized and high-quality study models should be introduced.

Objective : This experimental in vitro study investigates the effects of electro acupuncture stimuli to the DCX and PSA-NCAM positive cells in the dentate gyrus of spontaneously hypertensive rats. Methods : We used immunohistochemical methods to observe the change of neuron cells, and then counts the immunoactive cells under the $100{\times}$ visual field optical microscope. Results : 1. The counts of DCX-positive cells in the dentate gyrus significantly increased in the 2Hz group versus control group. Otherwise 100Hz group did not have a significant differance. 2. The counts of PSA-NCAM-positive cells in the dentate gyrus rather decreased in the both 2Hz group and 100Hz group versus control group. Conclusions : We find out the electro acupuncture stimuli have some effects upon cerebral neuron cell in the dentate gyrus spontaneously hypertensive rats.

Objectives : The purpose of this study was to observe the anti-oxidative effects of electroacupuncture at Pungyung($ST_{40}$) in rats. Methods : The author performed several experiments, including measurements of body weightrelative liver weightslevels of albumin, total bilirubin, LDL-cholesterol, LDH, GOT and GPT in serum levels of SOD, glutathione, catalase, NO and MDA in the liver and histological analysis of the liver. Results : 1. Liver index was decreased in the $ST_{40}-EA$ group compared with the holder group and the control group. 2. LDL-cholesterol was significantly decreased in the $ST_{40}-EA$ group compared with the group. 3. SOD activity was significantly increased in the $ST_{40}-EA$ group and $ST_{40}-NR$ group compared with the control group. Glutathione activity was significantly increased in the $ST_{40}-EA$ group compared with the control group, the holder group, and the Sham-EA group. Catalase activity was significantly increased in the $ST_{40}-EA$ group compared with the control group and the holder group. Conclusions : These results suggest that electroacupuncture at $ST_{40}$ has an antioxidant effect in rats.

The purpose of this study was to know the difference of the effect between the E- A and the S-A. The 19 patients complaining the pain on the neck, shoulder and upper limb were chosen, divided and controled by two groups; One was the E-A group treated at upper limb meridian point, the other was the therapy group treated by S-A at the scalp and E-A at upper limb meridian point together. In 20 minutes after treatment, the change of plasma cortisol concentration was observed. The results were as follows: 1. In E-A group, there was no significant change of plasma cortisol concentration. 2. In S-A and E-A group, there was significant increase to plasma cortisol concentration. In conclusion, it seems that the increased stimulation by the treatment of S-A and E-A together has close relation with the plasma cortisol concentration. And the further study about the intensity of acupuncture stimulation and S-A is expected.

Objectives : This study was to evaluate the effect of electroacupuncture on symptoms of peripheral facial paralysis. Methods : We investigated 34 cases of patients with Peripheral Facial Paralysis. We flip a coin and divide into two groups. Electroacupuncture was performed at one group, and the other group didn't do it. we evaluated the treatment effect of each group by using Gross Grading System of House-Brackmann, Yanagihara's Unweighed Grading System. Results : 1. In Pain back of the ear, we found that two groups have no significant differences. 2. As a result of evaluation by using Gross Grading System of House-Brackmann, Yanagihara's Unweighed Grading System, treatment score after 2weeks was marked higher than that before treatment and treatment score after 4weeks treatment was higher than treatment score after 2weeks within each group. 3. After 4weeks treatment, electroacupuncture group showed significant difference on Gross Grading System of House-Brackmann, Yanagihara's Unweighed Grading System compared with acupuncture group. Conclusion : These results suggested that electroacupuncture treatment should be more effective in the patient with peripheral facial paralysis.

Blood coagulation time, bleeding time, clot retraction ability, thrombocytes counts and hematological values under electroacpuncture anesthesis and medicament anesthesia, using 10 mongrel dogs were compared. The results were summarized as follows: 1. Blood coagulation time under electroacupuncture anesthesia was shorter than that under medicament anesthesia (p<0.001). 2. Bleeding time under electroacupuncture anesthesia was shorter than that under medicament anesthesia (p<0.01). 3. Clot retraction ability under electroacupuncture anesthesia was better than that under medicament anesthesia (p<0.01). 4. Thrombocytes counts under electroacupuncture anesthesia was more increased than that under medicament anesthesia (p<0.05). 5. Erythrocytes counts, hematocrit values, hemnglobin contents and leukocytes counts were decreased (p<0.01) under medicament anesthesia in comparison with control group, but there was no significant difference under electroacupuncture anesthesia.

Objectives : Electroacupuncture(EA) has been suggested as a treatment for stroke rehabilitation. But whether, how much, by what mechanism and when it is effective has not been answered satisfactorily. Therefore it is important to critically review clinical trials and laboratory researches about EA for stroke rehabilitation. Subjectives : We researched various recent sources of EA for stroke rehabilitation such as medical journals and especially tried to review methodologically best randomized controlled trials(RCTs). Results and Conclusions : 1) EA increases brain plasticity, activity, blood flow and secretion of neuropeptides in CNS. 2) EA is significantly effective at the case that more than half of the neural motor pathway is reserved. 3) The acupoints, frequncy and intensity of EA should be determined by patient-specific symptoms of stroke. 4) More studies is needed for merdian functions for stroke rehabilitation.

This study aims to examine the effects on nociceptive neuron excitability by application of electroacupuncture in rat with inflammation. It used 20 rats for experiment, divided them into control group, electroacupuncture group (EA group), caused hyperalgesia by injecting ${\lambda}$-carrageenan into hindpaw and conducted treatment three times for experimental period. Change of NFR(reaction time, RMS) showed no significant differences among EA group showed significant differences compared to control group from 48 hours. This study showed that EA group had an effect on nociceptive neurone excitability. Therefore, it is considered that electroacupuncture for pain control will be very desirable.
