Restless leg syndrome is a nervous system disorder that causes an overpowering urge to move one's legs. Symptoms of restless leg syndrome usually worsen when one tries to fall asleep and can prevent sufficient sleep. Restless leg syndrome is common in patients with chronic kidney failure and can be caused or worsened by chronic kidney failure and hemodialysis. Various medications can treat restless leg syndrome, though the long-term use of medications can cause augmentation and adverse effects. In addition, the use of dopamine agonists is limited in patients with chronic kidney failure. This is because the dose of administration should be controlled for patients with chronic kidney failure, and the treatment effect has not been clearly proven. This study reports the case of a 56-year-old male diagnosed with chronic kidney failure complaining of uncomfortable leg sensations. The patient underwent Korean medicine treatment using Jakyakgamcho-tang. The IRLS, NRS, and AIS scores were evaluation tools during treatment. This study suggested significantly improved symptoms through the individual interventions of Jakyakgamcho-tang in a restless leg syndrome patient with chronic kidney failure.

Paeoniae Radix, Glycyrrhizae Radix and Jakyakgamchotang have been used in Oriental Medicine for many centuries as a treatment for various disease. The purpose of the present study is to determine the effect of Paeoniae Radix, Glycyrrhizae Radix and Jakyakgamchotang on narepinephrine(NE) induced contraction of isolated rabbit femoral artery. Rabbits (2.0kg, female) were killed by CO₂ exposure and a segment (8-10mm) of the aortic ring from each rabbit was cut into equal segments and mounted 'in pairs' in a tissue bath. Contractile force was measured with force displacement transducers under 1.5g loading tension. The dose of NE which evoked 50% of maximal response (ED/sub 50/) was obtained from cumulative dose response curves for NE (10/sup -7/～10/sup -4/M). Contractions evoked by NE (ED/sub 50/) were inhibited significantly by Paeoniae Radix, Glycyrrhizae Radix and Jakyakgamcho-tang. The mean percent inhibition of NE induced contraction was 83.9% (p<0.01) after 150㎕/㎖ Paeoniae Radix, 101.1 %(p<0.01) after 150 ㎕/㎖, Glycyrrhizae Radix and 107.3%(p<0.01) after 150㎕/㎖ Jakyakgamcho-tang, Indomethacin slightly but significantly attenuated the inhibitory effects of Paeoniae Radix. Following treatment with indomethacin, the mean percent inhibition caused by 150㎕/㎖ Paeoniae Radix fell to 16.4% in femoral artery induced by NE contraction. Propranolol, ODQ, and L-NNA did not significantly alter the inhibitory effect of Paeoniae Radix. ODQ slightly but significantly attenuated the inhibitory effects of Glycyrrhizae Radix. Following treatment with ODQ, the mean percent inhibition caused by 150㎕/㎖ Glycyrrhizae Radix fell to 13.0% in femoral artery induced by NE contraction. Propranolol, indomethacin and L-NNA did not significantly alter the inhibitory effect of Glycyrrhizae Radix. L-NNA slightly but significantly attenuated the inhibitory effects of Jakyakgamchotang. Following treatment with L-NNA, the mean percent inhibition caused by 150㎕/㎖ Jakyakgamchotang fell to 13.8% in femoral artery induced by NE contraction. Propranolol, ODQ and indomethacin did not significantly alter the inhibitory effect of Jakyakgamcho-tang. These results indicate that Paeoniae Radix, Glycyrrhizae Radix and Jakyakgamcho-tang can relax NE induced contraction of the isolated rabbit femoral artery, and that this inhibition related to nitric oxide.

Objectives Danggwisoo-san and Jakyakgamcho-tang are frequently prescribed for traffic accident patients in Korea. The aim of this study was to examine index compound analysis, antioxidant activity and amount of starch measurement by extraction method. Methods Danggwisoo-san and Jakyakgamcho-tang were extracted with water and 70% ethanol. Antioxidant activity was measured by 2,2-Diphenyl-1-picrylhydrazyl, 2,2-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) and ferric reducing antioxidant power according to the standard protocol. The contents of the indicator components nodakenin, paeoniflorin, and glycyrrhizin were measured by high-performance liquid chromatography, respectively. All starches were hydrolyzed and then total D-glucose was measured and compared. Results Antioxidant activity was excellent in 70% ethanol in all assays. The index component was jagged because its solubility was different depending on the extraction solvent. Starch content was significantly lower in 70% alcohol extract than water extract. Conclusions The results of this study showed that physiological activities and components are different according to extraction conditions. Each herbal medicine has a suitable extraction solvent. Also, the difference in starch content is an object to be considered as it may affect digestion and absorption.

Objectives : Jakyakgamcho-tang (JGT) has been traditionally used to treat muscular convulsion and pain in South Korea. According to recent studies, JGT has been reported to have anti-depression, anti-inflammation, anti-oxidative, anti-diabetics, anti-spasm and analgesic effects, but studies on its anti-neuroinflammatory and neuroprotective effect have not been deeply conducted. Thus, we investigated the anti-neuroinflammatory activity of JGT on lipopolysaccharide (LPS)-stimulated mouse microglia cells. Methods : To investigate the anti-neuroinflammatory effects of JGT on BV2 microglial cells, we examined the production of nitric oxide (NO) using griess assay, and mRNA expressions of pro-inflammatory cytokines such as interleukin (IL)-1𝛽, IL-6, and tumor necrosis factor (TNF)-𝛼 using real time RT-PCR. Furthermore, to determine the regulating mechanisms of JGT, we investigated the heme oxygenase (HO)-1 by real time RT-PCR. Results : Pre-treatment of JGT effectively decreased NO production in LPS-stimulated BV2 cells at concentrations without cytotoxicity. Additionally, JGT significantly suppressed the production of IL-1𝛽, IL-6, and TNF-𝛼 in LPS-stimulated BV2 cells. Furthermore, JGT activated the HO-1 expression, which is one of the immunomodulatory signaling molecules. And the abolishment of HO-1 by tin protoporphyrin IX (SnPP, the HO-1 inhibitor) reversed the anti- inflammatory activity of JGT in LPS-stimulated BV2 cells. Conclusions : Our results suggest that the JGT has anti-neuroinflammatory effect through the activation of HO-1 in LPS-stimulated BV2 cells. Thereby, JGT could expected to be used for the prevention and treatment of neurodegenerative disease related to neuroinflammation.

MRSA is Staphylococcus aureus resistant to β-lactam antibiotics, and is a worldwide infectious disease. Even with the discovery of new antibiotics, resistance develops rapidly, so new alternatives are needed. Jakyakgamcho-tang (JGT) is a combination of Jakyak and Gamcho, and has been mainly used as an antispasmodic and analgesic in oriental medicine. This study was conducted to find out whether there is an effect on MRSA in relation to the anti-inflammatory effect of JGT and the antibacterial effect of Jakyak and Gamcho found in previous studies. In this study, in order to investigate the antibacterial activity of JGT and the combined effect of existing antibiotics, after extracting JGT with 70% EtoH, the disc diffusion method, minimum inhibitory concentration (MIC), drug combination effect (FICI), and time-kill analysis (Time-kill assay), metabolic inhibition, Western blot and qRT-PCR analysis were used to confirm the antibacterial activity mechanism of MRSA of JGT. As a result of the experiment, all of MRSA showed antibacterial activity in JGT's disc diffusion method, and the MIC was 250-1000 ㎍/mL. When existing antibiotics and JGT were combined with drugs, most had synergy or partial synergy. In addition, it was confirmed that the degree of bacterial growth was suppressed over time when simultaneous administration for 24 hours. JGT showed a synergistic effect when administered together with the ATPase-inhibitor DCCD, suggesting that it affected the inhibition of ATPase. As a result of observing the expression of PBP2a, and hla protein in the JGT-treated group and the untreated control group through wstern blot, it was confirmed that the protein expression of the JGT-treated group was significantly suppressed, and the expression levels of mecA, mecR1 and hla genes were also suppressed during JGT treatment. was observed by qRT-PCR. Combining the results of the experiment, it can be seen that JGT has antibacterial activity in MRSA, and when combined with existing antibiotics, the effect was increased compared to treatment with the drug alone. This suggests that JGT can be an alternative to treatment for antibiotic resistance of MRSA.
