BackgroundGanghwaljetongyeum (GHJTY) is a complex herbal decoction comprising 18 plants; it is used to treat arthritis. In order to develop a new anti-arthritic herbal medication, we selected 5 out of 18 GHJTY plants by using bioinformatics analysis. The new medication, called ChondroT, comprised water extracts of Osterici Radix, Lonicerae Folium, Angelicae Gigantis Radix, Clematidis Radix, and Phellodendri Cortex. This study was designed to investigate its chondroprotective and anti-inflammatory effects to develop an anti-arthritic herb medicine.MethodsChondroT was validated using a convenient and accurate high-performance liquid chromatography–photodiode array (HPLC–PDA) detection method for simultaneous determination of its seven reference components. The concentrations of the seven marker constituents were in the range of 0.81–5.46 mg/g. The chondroprotective effects were evaluated based on SW1353 chondrocytes and matrix metalloproteinase 1 (MMP1) expression. In addition, the anti-inflammatory effects of ChondroT were studied by Western blotting of pro-inflammatory enzymes and by enzyme-linked immunosorbent assay (ELISA) of inflammatory mediators in lipopolysaccharides (LPS)-induced RAW264.7 cells.ResultsChondroT enhanced the growth of SW1353 chondrocytes and also significantly inhibited IL-1β-induced MMP-1 expression. However, ChondroT did not show any effects on the growth of HeLa and RAW264.7 cells. The expression of cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) was induced by LPS in RAW264.7 cells, which was significantly decreased by pre-treatment with ChondroT. In addition, ChondroT reduced the activation of NF-kB and production of inflammatory mediators, such as IL-1β, IL-6, PGE2, and nitric oxide (NO) in LPS-induced RAW264.7 cells.ConclusionsThese results show that ChondroT exerted a chondroprotective effect and demonstrated multi-target mechanisms related to inflammation and arthritis. In addition, the suppressive effect was greater than that exhibited by GHJTY, suggesting that ChondroT, a new complex herbal medication, has therapeutic potential for the treatment of arthritis.
Objectives This study was designed to investigate the effects of ChondroT on thrombus in FeCl3-induced rats. Methods We exposed FeCl3 to rat's carotid artery to induce thrombus. Specimens were divided in 5 groups; Intact, Control, ASA10 (aspirin 10 mg/kg), CT100 (ChondroT 100 mg/kg), and CT200 (ChondroT 200 mg/kg), each n=6. We investigated thromboxane, platelet activating factor (PAF), histological change, lipid metabolism, transaminase, leukocyte, erythrocyte and thrombocyte level. Results In ASA10, CT200 groups, there was significants decrease in both thromboxane level and total cholesterol level, compared to control group and there were significant histological changes of blood vessel, compared to control group. In CT200 group, there was significant decrease in PAF level, compared to control group (p<0.05). In ASA10, CT200 groups, triglycerides level tended to decrease, compared to control group. Conclusions Based on these results, it could be suggested that ChondroT was effective on thrombus in FeCl3-induced rats, and further study is needed to conduct a rigorous clinical research.
Objectives The purpose of this study is to present evidence by analyzing the research trends in acupuncture treatment in the last 10 years for thromboangiitis obliterans. Methods Randomized controlled trials about acupuncture on thromboangiitis obliterans were searched China National Knowledge Infrastructure (CNKI), PubMed,
Background:In South Korea, a few patients with low back pain (LBP) are currently being treated with a combination of traditional Korean medicine (KM) and Western medicine (WM). Although a recent research has reported results regarding patient satisfaction and exploratory effectiveness, evidence of comparative effectiveness still needs to be reviewed. The aim of this study is to evaluate the clinical and cost-effectiveness of KM and WM collaborative treatment (CT) compared with that of sole treatment (ST) for patients with LBP in Korea.Method/design:This multisite, prospective observational comparative effectiveness research study is part of a nationwide pilot project for KM and WM collaboration launched by the Korean Ministry of Health and Welfare. The duration of the study is 8 weeks, and the target number of inclusion is 360 patients. Participants receive treatment according to their treatment plan, and a researcher conducts investigations thrice, every 4 weeks. In the final analysis, the merged data from the participants’ questionnaire responses, hospital medical records, and administrative data, and Health Insurance Review and Assessment service data will be compared between the CT and ST groups.Discussion:This study will provide clinical and economic information about CT for LBP, which might be a milestone for establishing future polices about this collaboration in Korea.Trial registration:The study protocol has been registered with the Clinical Research Information Service (KCT0002827).
