Unlike most bacteria, Treponema pallidum subspecies cannot be readily isolated or sustained in cell culture for numerous generations. In korea, two non treponemal tests are currently considered as standard; the VDRL slide test and RPR card test. These tests are based on an antigen composed of an alcoholic solution containing measured amount of cardiolipin, cholesterol, and sufficient purified lecithin to produce reactivity. The nontreponemal reagin tests measure immunoglobulin M (IgM) and IgG to lipoidal material released from damaged host cells as well as to lipoprotein-like material and possibly by cardiolipin released from the treponemes. The object of the evaluation was to evaluate the performance of the Mediace RPR kit on the automated biochemistry analyzer system as a method for screen method of syphilis as well as to identify BFP possibility. For evaluation of routine screening test, a total 2,380 specimens tested by Mediace RPR from 28th Oct, 2007 to 22th Feb, 2008. For evaluation of BFP possiblility, we measured samples which have potential BFP reaction in Syphilis test such as ANA (anti-nuclear antibody) positive (135 samples), CRP (C-reactive protein) positive (100 samples), RF (Rheumatoid factor) positive (26 samples), and other potential BFP cases (17 samples) including total 278 samples. These samples were tested quantitative test Mediace RPR with Hitachi 7600 P module. For comparison with current manual test, VDRL slide test were performed. Of these 2380 specimens, 2350 were negative, 30 were positive, and one were positive with TPHA. Both methods agreed for 2356 (98.9%) samples. Of the 30 samples showed positive results over 1.0 R.U, 6 samples showed positive results with VDRL test. Of these 6 samples, 1 samples showed positive with TPHA test. The combination of the Automated Biochemistry analyzer and VDRL test for retest can be increase efficiency of syphilis screening test.
Autoimmune arthritis, such as rheumatoid arthritis (RA), is a chronic inflammatory disorder that primarily affects the joints and then results in their progressive destruction. Effector Th cells have been classified as Th1 and Th2 subsets based on their cytokine expression profiles and immune regulatory function. Another subset of T cells termed Th17 was recendy discovered and known to selectively produce IL-17. Also, Th17 was shown to be generated by TGF${\beta}$ and IL-6 and maintained by IL-23. IL-17 is a proinflammatory cytokine that is considered to involve the development of various inflammatory autoimmune diseases such as RA, asthma, lupus, and allograft rejection. IL-17 is present in the sera, synovial fluids and synovial biopsies of most RA patient. IL-17 activates RA synovial fibroblasts to synthesize IL-6, IL-8 and VEGF via PI3K/Akt and NF-${\kappa}B$ dependent pathway. IL-17 increases IL-6 production, collagen destruction and collagen synthesis. In addition, it not only causes bone resorption but also increases osteoclastogenesis and fetal cartilage destruction. Inhibition of the IL-17 production may contribute a novel therapeutic approach along with potent anti-inflammatory effect and with less immunosuppressive effect on host defenses.
Objectives: The purpose of this study was to investigate the current trends in research on pharmacopuncture in Korea since 2007. Methods: A literature review was performed by using the search engines 'Science and Technology Society Village', 'Korean Studies Information Service System', 'National Discovery for Science Leaders', and 'Oriental Medicine Advanced Searching Integrated System' in Korea from January 2007 to December 2013. Searched key words were 'pharmacopuncture', 'herbal acupuncture', 'aqua-acupuncture', and 'bee venom'. Finally, we selected 457 papers, including Korean experimental studies and clinical studies. Selected papers were classified according to year of publication, type of pharmacopuncture, disease & topic, research type and the publishing journal. Results: One hundred fifty pharmacopunctures were studied in 457 papers. Single compound pharmacopuncture was the most studied pharmacopuncture in experimental studies while animal-based pharmacopuncture was the most studied pharmacopuncture in clinical studies. Bee venom placed first among the various pharmacopunctures, followed by placenta, sweet bee venom, mountain-ginseng, and anti-inflammatory pharmacopunctures. Experimental research on pharmacopuncture has fallen since 2007 when 55 papers were published. However, clinical research has been increasing steadily. In clinical studies, case reports were numerous than randomized clinical trials (RCTs). Musculoskeletal diseases were the most frequently-treated diseases in studies on pharmacopuncture; among the musculoskeletal diseases, rheumatoid arthritis was the most frequently-treated disease in experimental studies and low back pain was the most frequently-treated condition in clinical studies. Since 2007, 45 different journals have published studies on pharmacopuncture, with the Journal of the Korean Acupuncture and Moxibustion Medicine Society having the largest number of papers on pharmacopuncture and the Journal of Pharmacopuncture the second largest number. Conclusion: The trends in research on pharmacopuncture published in studies from 2007 to 2013 were similar to those in studies published before 2006. Many studies on pharmacopuncture focused on bee venom and musculoskeletal diseases. Additional studies on diverse types of and indications for pharmacopuncture are needed.
Objectives & Methods : The purpose of this study is to observe the effects of Coicis Semen Herbal-acupuncture solution (CS-HAS) at the Joksamni (ST36) on the collagen-induced arthritis in the DBA/1J mouse. The author performed several experiments to analyze the effects of CS-HAS on arthritis; change of the weight; the spleen size and adhesion rate; serum cytokine levels; serum antibody levels; changes of immunocyte counts; the histological changes of joint. Results : In the Coicis Semen Herbal-acupuncture (CS-HA), arthritis index, the incidence of arthritis, and the degree of joint edema were decreased. In CS-HA, there was no weight loss. The size of the spleen, adhesion rate, and the edema and transformation of joint were lowered. In CS-HA, the levels of IL-1${\beta}$, IL-6, TNF-${\alpha}$, IFN-${\gamma}$, IgG, IgM, and anti-collagen II in serum and the levels of IFN-${\gamma}$, IL-4, IL-10 in spleen were significantly decreased. In CS-HA, the expression ratios of $CD45^+$ to $CD3e^+$ and $CD8^+$ to $CD4^+$ were decreased. Also, the overall $CD4^+/CD8^+$ cell ratio was lowered in spleen. Ratios of the $CD4^+/CD25^+$, $CD45^+/CD69^+$ cells were decreased in lymph nodes. In addition, ratios of the $CD3^+/CD69^+$, $CD11b^+/Gr-1^+$ cells were also decreased in synovium. In the histological study, the cartilage destruction and synovial cell proliferation, and collagen fiber destruction were decreased with CS-HA treated group. Conclusions : From the results mentioned above, it is suggested that CS-HA at the ST36 has several significant effects on the collagen-induced arthritis.
Objective: Bee venom (BV) has been used for the treatment of inflammatory diseases such as rheumatoid arthritis and relief of pain in Oriental medicine. The two main components of BV are melittin and phospholipase A2 (PLA2). Of these, melittin, the major active ingredient of BV, has been reported to induce apoptosis and to possess anti tumor effects. Several studies have established that the agents inducing apoptosis in target organs suppress tumorigenesis. As the other component, PLA2 has been reported to induce neurite outgrowth in PC12 cells. However, there was no report about proliferative effect of BV in neuronal cells. In order to examine the effect of BV on glioma cell, human glioma cell line, U87 was used. Methods: Analysis of proliferation was confirmed by MTT assay. BV increased cell number through dose and duration dependent manner and these effects are apparent at a concentration of 10 ug/ml. To observe which signaling molecules will be activated by BV, phosphorylation of Akt, MAPK, PYK2 or CREB were examined by Western blot analysis. To study the long term effect of BV in U87 cells, the image of cells treated with BV for 4 days were obtained. Results: The phosphorylation levels of PYK2 and Akt were increased at 5 min after addition of 10 ug/ml of BV and sustained to 2 hours. On the other hand, phosphorylation of MAPK and CREB were increased at 5 min, maximum at 10 min, and returned to 30 min. These imply that BV may activate two different signaling pathways, PYK2/Akt and MAPK/CREB. BV treated cells showed increased neurite number and length. Conclusion: These results propose that BV may induce differentiation as well as proliferation of U87 cells through the activation of PYK2/ Akt and MAPK/ CREB.
Ibuprofen (IBU), is a non-steroidal anti-inflammatory drug, used to treat rheumatoid arthritis, removal of fever and mild to moderate pain. Because of small dosage and very low accumulation in the body, IBU has been used to heal children's fever. However, IBU was very low solubility in a low pH and water (in water $0.03{\sim}2.5$ mg/ml). A nanoemulsion containing IBU by means of self-microemulsion drug delver system (SMEDDS) was prepared in order to enhance the solubility of IBU. The SMEDDS was composed of cosurfactant, oil and surfactant The solubility of IBU in various components such as cosurfactant, oil and surfactant was examined. $Carbitol^{\circledR}\;(386.99{\pm}20.5\;mg/ml)$ as a cosurfactant, $Labrafil^{\circledR}$ M1944CS $(90.16{\pm}1.60mg/ml)$ as an oil and $Cremopher^{\circledR}$ RH-40 $(239.01{\pm}2.8\;mg/ml)$ as a surfactant were used in this study for preparing SMEDDS. Optimized formulation of SMEDDS was obtained by phase diagram which express the section of nanoemulsion formation. The SMEDDS containing IBU had higher dissolution rate than conventional IBU sirups. Thus the SMEDDS was a potential candidate of stable conventional and effective oral dosage form for IBU.
Talniflumate is a nonsteroidal anti-inflammatory drug (NSAID), which has been used treat of rheumatoid diseases, is insoluble in water, therefore it has low bioavailability after oral administration. The purposes of this study were to prepare O/W or W/O microemulsions for solubilization of poorly water soluble drug, talniflumate and to formulate into other dosage form. For this purpose, we made O/W or W/O microemulsion with oil(soybean oil, IPM), surfactant (Cremophor $EL^{(R)}$, Tween 80) and water or propylene glycol and evaluated solubility of talniflumate. The microemulsion systems were very stable and showed transmittance above 95% without flocculation or aggregation. Especially, the solubility of talniflumate in the formulation B-1 containing 18% of isopropyl myristate and 71% of tween 80 was 10 times higher than that of other O/W microemulsions. The addition of propylene glycol and N-methylglutamine to the fomulation B-1 showed excellent capacity on the solubilization of talniflumate and the percentage was almost 2.0%. These results suggest that the microemulsion system may be promising for the solubility improvement of talniflumate.
Purpose: Periodontitis is an infectious disease caused predominantly by gram-negative anerobes. The host inflammatory response to these bacteria causes alveolar bone loss that is characterized as periodontitis. Omega-3 fatty acids (${\omega}$-3 FAs) have anti-inflammatory properties, thus have been used to treat some chronic inflammatory diseases such as cardiovascular disease and rheumatoid arthritis. We aimed to evaluate the effect of dietary supplementation with ${\omega}$-3 FAs as a host modulating agent in patients with chronic periodontitis. Methods: Sixty otherwise healthy subjects with moderate and severe chronic periodontitis were enrolled in our randomised, double-blind, placebo-controlled trial. The control group (CG, n=30) was treated with scaling and root planing (SRP) and given a placebo; the treatment group (TG, n=30) was treated with SRP and dietary supplementation of ${\omega}$-3 FAs (one 300 mg tablet daily for 12 weeks). Periodontal clinical parameters and serum C-reactive protein (CRP) levels were evaluated in all patients at baseline, a 6-week and 12-week period after treatment. Results: A significant reduction in the gingival index, sulcus bleeding index, pocket depth, and clinical attachment level was found in the TG compared to the CG at a 12-week period. However, no statistically significant changes in serum CRP levels were found. Conclusions: Our findings suggest that ${\omega}$-3 FAs can successfully reduce gingival inflammation, pocket depth, and attachment level gain. Dietary supplementation with ${\omega}$-3 FAs may have potential benefits as a host modulatory agent in the prevention and/or C management of chronic periodontitis.
Objective : The aim of this study was to investigate anti-arthritic effects of Honghwa-ja herbal acupuncture extract through inhibitory MIF activation. Methods: After Rheumatoid arthritis(RA) knee joint was induced by lipopolysaccharide(LPS) in vivo, Honghwa-ja herbal acupuncture solution was applied on $ST_{35}$(犢鼻) and $EX-LE_{202}$(內膝眼) coresponding human body. To research the effect on the expression of MIF, COX-2, MMP-9 mRNA, RT-PCR was performed on LPS-stimulated Raw 264.7 cells. Results: In the Honghwa-ja herbal acupuncture solution treated Raw 264.7 cell, the mRNA expression of cytokines, RA related inflammation factors, such as the MIF, COX-2, and MMP-9 reduced concentration dependently. Positive reaction of RA-related cytokines MIF, $IL-6R-{\alpha}$, STAT3, COX-2, MMP-9 was reduced. Conclusion : Honghwa-ja herbal acupuncture extract has significant protecting ability against acute progressive RA by inhibiting the production of MIF, as a top in cytokines related to inflammation.
Inflammatory cells may produce active species of oxygen in antimicrobial defense. While such species can directly damage surrounding tissue, their major secondary role may be to mediate important components of the inflammatory response. Superoxide dismutase, antioxidant, have significant anti-inflammatory properties in rheumatoid arthritis, ischemic tissue injury and gastrointestinal disease. Increased oxidative product formation diseases. And superoxide dismutase produced by Porphyromonas Gingivalis is resistant to killing by polymorphonuclear leukocyte. The purpose of this study was to investigate on the effects of superoxide dismutase in 3T3 fibroblast and in experimental gingivitis in the rats. The effect of superoxide dismutase(SOD) to cell morphology and cell activity was measured in cultured mouse 3T3 fibroblast. After experimental gingivitis were induced by lipopolysaccharide(LPb) and bovine serum albumin(BSA), injection of SOD were done. WBC count and histologic findings were observed at 1, 2, 3, and 7 days. The results were as follows; 1. There was a little difference between LPS treated groups and SOD treated groups in 3T3 fibroblast morpholoy. 2. There was no difference between only SOD treated groups (except SOD 150U at 3days) and control in 3T3 fibroblast activity. 3. LPS $0.5{\mu}g/ml$ and SOD treated groups (except 150U) had decreased 3T3 fibroblast activity and no significant difference at 3 days. 4. LPS $5.0{\mu}g/ml$ and SOD treated groups were significantly increased cell activity of 3T3 fibroblast than control group at 1 day(P<0.05). 5. In LPS induced gingivitis, the number of leukocytes in SOD treated was significantly decreased than in saline treated at 1 day(P<0.05). 6. In histopathologic findings of LPS or BSA induced gingivitis, inflammatorycell infiltration in SOD treated groups were less than in saline treated group at 1, 2 and 3 days.
