Purpose: We investigated the effects of the combined therapy in rats with rheumatoid arthritis induced by type II collagen for 28 days, which consisted of the oral administration of the AR and EA applied to zusanli acupoint(ST36). Methods: Normal group was oral administered with 0.9% NaCl $0.5\;m{\ell}/day$ to normal rats. Control group was oral administered with 0.9% NaCl $0.5\;m{\ell}/day$ to arthritic rats. Group I was oral administered with AR 500 mg/kg $0.5\;m{\ell}/day$ to arthritic rats. Group II was given 2 Hz EA of ST36 in the test group for 30 min/day to arthritic rats. Group III was oral administered with AR 500 mg/kg $0.5\;m{\ell}/day$ and 2 Hz EA of ST36 in the test group for 30 min/day to arthritic rats. We Observed effect of the histopathological changes by H&E stain of liver, kidney, knee joint and ELSIA of cytokines($TNF-{\alpha}$). Results: 1. The vacuolization of liver tissue was decreased in group I, II, III comparing with control group. 2. The glomerular sclerosis of kidney tissue was decreased in group I, II, III comparing with control group. 3. The erosion of arthritic site of knee joint tissue was decreased group I, II, III comparing with control group. In particular group III was the most effective comparing with group I, II on the histopathological view. 4. In the ELSIA test of $TNF-{\alpha}$ concentration, Control group significantly increased in the concentration more than group I, II, III. The rate of increase in concentration slowed down in group III more than group I, II(p<0.05). Conclusion: It is concluded that 500 mg/kg of AR extracts and EA have clear therapeutic effect on the rheumatoid arthritis.

The present study aims to investigate a possible mechanism of electroacupuncture (EA) in the spinal dorsal horn that may underlie N-methyl-D-aspartate (NMDA) receptor-associated extracellular signal-regulated kinase (ERK) mitogen-activated protein kinase (MAPK) signaling pathways. The hot plate latency of the ipsilateral hindpaw of EA-treated rats was significantly decreased compared with complete Freund's adjuvant (CFA)-injected ones. The expressions of NR1 and NR2B subuint mRNA of NMDA receptor in the whole L4-5 segments are decreased by CFA treatment, but NR2B subunit was significantly recovered by EA treatment. When we detected the expression of ERK, there were no significant difference between normal and CFA-treated rats with EA or NMDA receptor antagonist MK801. But phosphorylated ERK expressions were markedly induced by CFA, but these inductions were significantly modulated by EA treatment. Although hosphorylation of ERK was also arrested by MK801, these inductions of CFA-injected rats was markedly inhibited only by co-treatment with EA and MK801. Phosphorylated cAMP response element-binding protein (CREB), ERK-related transcriptional factor, showed a significant increase in CFA-treated rats and this increase was slightly inhibited by EA and MK801 treatments. But immunoreaction for phosphorylated CREB were significantly increased by CFA treatment in the superficial laminae of the dorsal horn and these inductions were significantly arrested by co-treatment of EA and MK801. Consequently, the hyperalgesia induced by CFA are associated NMDA receptor and EA and MK801 may showed anti-hyperalgesia via same mechanism for inhibition of ERK and CREB phosphorylation in the dorsal horn.

The purpose of this case study is to show a case of acute posterior cruciate ligament(PCL) complete injury improved by conservative acupuncture therapy. The patient was treated for 100 days. The patient received deep interarticular electroacupuncture(EA) stimulation at S35, LE200, LE211 and treated by other acupoint stimulation, herb medication, cupping, physical treatments and exercise. We evaluated through MRI and Lysholm knee score. We suggest to treat acute posterior cruciate ligament(PCL) injury with acupuncture therapy meaning conservative therapy and would like to research acupuncture treatment plan for the further treatments.

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.

The aim of this study was to examine the effects of electroacupuncture(EA) at the PC6 (Naegwan) on normal humans using KarhunenLoeve decomposition method. Electroencephalogram(EEG) is a multi-scaled signal consisting of several components of time series with different dominant frequency ranges and different origins. EEG KarhunenLoeve decomposition method exibit site-specific and state-related differences in specific frequency bands. In this study, KarhunenLoeve decomposition method was used as a measure(D2) of complexity. 30 channel EEG study was carried out in 10 subjects (10 males; $age=21.4{\pm}0.5$ years). Results : We found that the average values and standard deviations of D2 at FP1, FP2, FTC1, FTC2, TT1, TT2, T4, TCP1, P3, P4, T6, OZ channel (p<0.05) were higher than during the acupuncture treatment, and the average values and standard deviations of D2 at F3, F8 channels(p<0.05) were lowered than during the acupuncture treatment. However, the comparison with that before and after the treatment shows no significant differences in all channels.

The aim of this study was to examine the effects of low frequency electroacupuncture(EA) at the $B_{62}$ (Shinmaek) $K_6$(Chohae) on vascular dementia in humans using nonlinear dynamics. Electroencephalogram(EEG) is a multi-scaled signal consisting of several components of time series with different dominant frequency ranges and different origins. Nonlinear measures of the EEG like the correlation dimension ($D_2$) and the first positive Lyapunov exponent ($L_1$) reflect the complexity of the EEG. In this study, $D_2$ was used as a measure of complexity. Sixteen channel EEG study was carried out in six subjects (5 females and 1 males; $age=83.83{\pm}7.19years$). We found that the baseline $D_2$ values of the EEG at F4 and F8 channels (P<0.01) were lowered than during the acupuncture treatment, indicating decreased complexity of the EEG. However, the comparison with that before and after the treatment shows no significant differences in all channels.

This study was carried out to investigate the effects of electrical stimulation on the change Tyrosine-Hydroxylase immunoreactive(TH-IR) cells in the Central gray and retrorubral field of the male SD rats. 9 healthy and normal rats were divided into three groups, 3 SD rat in each group. The one group has been stimulated by electroacupuncture(EA, 2Hz) for 30min and the other group by EA for 1hr 30min and control group has been stimulated. TH-IR cells were found in the Central gray(CG) and Retrorubral field(RF). The numbers of TH-IR cells of CG and RF were significantly increased after 30 min (CG $6.2{\pm}0.83$, RF $1.4{\pm}0.55$)as compared with control group(CG $24{\pm}3.16$, RF $6.4{\pm}0.55$) and were also significantly increased after 1hr 30min(CG $75.6{\pm}4.51$, RF $18.8{\pm}0.89$) than 30min. These results show that TH is related into CG and RF in response to electrical stimulation.

Objectives: The purpose of this study was to summarize current research trends and results regarding acupuncture treatment for hypertension. Methods: Articles published from 2009 to 2019 were searched on domestic databases (OASIS, NDSL, RISS) and PubMed using the keywords 'Hypertension', 'Hypertensive', 'Acupuncture', 'EA' (electroacupuncture), 'Autonomic nervous system', 'ANS', 'CVD' (cardiovascular disease), '고혈압', '침', '전침', and '자율신경계'. The studies were analyzed according to the year, type of study (domestic or foreign articles, nationality of the first author), acupuncture type for human and animal studies, BP (blood pressure) measurement, and acupuncture intervention. Results: In total, 21 articles were selected. There were 8 randomized controlled trials (RCTs), 3 non-randomized controlled trials (nRCTs), 2 before-after studies, 1 case series, and 7 animal studies. Manual acupuncture (11 articles) was most frequently used, and ST36 (足三里) was most frequently used in human studies. In 18 of 21 articles, acupuncture was reported as effective in lowering systolic blood pressure (SBP) or diastolic blood pressure (DBP) in hypertensive patients. Conclusions: Acupuncture treatment for hypertension is deemed useful. Further studies are necessary for application of acupuncture therapy in clinical practice.
