The aim of this study was to find the non-invasive optimal alternative method for Manual Acupuncture. Existing researches had reported that Transcutaneous Electrical Acupoint Stimulation (TEAS) was an effective treatment method instead of manual acupuncture. In place of the TEAS, we suggested the Pulsed Electromagnetic Fields (PEMFs). Thus, we designed the PEMFs system which can stimulate only an acupoint. There have been no researches which reported therapeutic effect when stimulating at an identical acupoint by TEAS and PEMFs. Hence, this study investigated the therapeutic effect on the muscle fatigue after the strenuous knee extension/flexion exercise by two stimulations. We selected the stimulation method of both TEAS and PEMFs by using 2Hz biphasic rectangular wave pulse and pulse width 0.2ms. The magnetic flux was the 30.92mT (309.2gauss) at 2 Hz. The electromyogram (EMG) and the maximal voluntary contraction (MVC) at rectus femoris were measured. The Median Frequency (MF) at TEAS group was significantly effective at 6 minutes (p=0.499). The PEMFs group was recovered to the MF rapidly after 4 minutes (p=0.166). The results of the peak torque indicated that both non-stimulation group and TEAS group did not recover to the peak torque at pre-exercise during the recovery period (p<0.05). In contrast, the significant treatment effect of PEMFs group was found after 14 minutes (p=0.135). The results of this study demonstrated that PEMFs were better than TEAS as a non-invasive method to replace the manual acupuncture.

Obesity is the state of excessive body fat accumulation and is mainly caused by consuming more calories than are burned through physical activity. Herbal acupuncture (HA), also known as pharmacopuncture, has been increasingly used in clinics of Korean medical to alleviate obesity. This review analyzed four clinical studies and 16 animal studies on the effectiveness of HA as a treatment for obesity. Clinical evidence suggests that various kinds of HA might be beneficial for treating obesity; however, further investigations with well-designed, evidence-based, randomized clinical trials are needed. Animal studies support the idea that HA might be beneficial for the treatment of obesity and provide possible mechanisms, such as anti-inflammation, antioxidation, modulating lipid metabolism and so on, to explain the effect of HA on obesity. This review, based on the evidence collected, suggests that HA could have a beneficial effect for alleviating obesity by modulating inflammation, oxidative stress, lipid metabolism, leptin, and the insulin signal.

Background Obesity is a main cause of insulin resistance (IR), metabolic syndrome, and fatty liver diseases. This study evaluated Euphorbia kansui radix (Euphorbia) as a potential treatment option for obesity and obesity-induced IR in obese human and high-fat diet- (HFD-) induced obese mice. Methods In the human study, we analyzed the body weight change of 14 patients who took a single dose of 6 g of Euphorbia powder. In the animal study, male mice were divided into three groups: normal chow, HFD, and Euphorbia (high-fat diet and 100 mg/Kg Euphorbia once per week). Body weight, epididymal fat pad weight, fasting blood glucose, fasting insulin, HOMA-IR, and oral glucose tolerance test were measured. Also, macrophage infiltration and expression of CD68, tumor necrosis factor- (TNF-) α, interferon- (IFN-) γ, and interleukin- (IL-) 6 genes in the liver and adipose tissue were analyzed. Results The human study showed that Euphorbia has a potential effect on body weight loss. In the in vivo study, body weight, epididymal fat weight, glucose level, IR, expression of CD68, TNF-α, IFN-r, and IL-6 genes, and macrophages in liver and adipose tissue were significantly reduced by Euphorbia. Conclusions These results suggest that Euphorbia attenuates obesity and insulin resistance via anti-inflammatory effects.

Development of a Multi-frequency Impedance Measurement System for Acupuncture Points and Preliminary Report of Measurement Results

Objectives: The purpose of this paper was to suggest a new diagnostic method to estimate the electrical properties at acupoints. Thus, we developed a multi-frequency bioelectrical impedance measurement system to analyze the state of bioions in body fluids, not the skin impedance at an acupoint, for various body compositions. Methods: At low frequencies, the current does not penetrate the cell membrane, and at high frequencies, the current passes through both intracellular and extracellular fluids because of a decrease in the cell membrane’s impedance. To confirm the effect of the composition of an extracellular fluid or an intracellular fluid in a segment such as an acupoint, are developed a system to detect the acupoint potential at 5, 50 and 200 KHz between two adjacent points in the areas of LU3, LU4 and LU9. Results: The detected acupoint potential decreased with increasing frequency. A correlation analysis of identical left/right acupoints showed a high correlation for three types of acupoint potentials at multiple frequencies. Moreover, we observed a low correlation at 5 KHz, which is a significant factor to be considered for the unbalanced relationship between identical acupoints. Conclusions: On the basis of a meridian theoretical point of view, we may infer the acupoint’s physiological composition by using the multi-developed frequency bioelectrical impedance measurement system.
