Objective : Lumbar disc herniation can induce sciatica by mechanical compression and/or chemical irritation. The aim of this study was to compare the effects of GCSB-5 (Shinbaro$^{(R)}$) and NSAIDs on pain-related behavior and on the expressions of microglia, astrocytes, CGRP, TRPV1, IL-6, and CX3CL1 in a rat model of lumbar disc herniation. Methods : 112 male Sprague-Dawley rats underwent implantation of nucleus pulposus to a dorsal root ganglion (DRG). Rats were divided into five groups as follows; a saline group (the vehicle control group) (n=27), a 10 mg/kg aceclofenac group (the aceclofenac group) (n=22), and 100, 300 or 600 mg/kg GCSB-5 groups (the GCSB-5 100, 300, or 600 groups) (n=21 for each group). Rats were tested for mechanical allodynia at 3 days after surgery and at 1 day, 3 days, 7 days, 14 days, 21 days, 28 days, 35 days, 42 days, 49 days, and 56 days after treatment commencement. Immunohistochemical staining of microglia (Iba1), astrocytes (GFAP), CGRP, and TRPV1, and PCR for IL-6 and CX3CL1 were performed on spinal dorsal horns and DRGs at 56 days after medication commencement. Results : After 56 days of GCSB-5 300 administration, mechanical withdrawal thresholds were significantly increased (p<0.05), and immunohistochemical expressions of Iba1, GFAP, CGRP, and TRPV1 were reduced than other groups, but this difference was not statistically significant. Conclusion : These results indicate GCSB-5 reduces mechanical allodynia and downregulates neuroglial activity and the expressions of CGRP and TRPV1 in the spinal segments of a rat model of lumbar disc herniation.

Synovitis acne pustulosis hyperostosis osteitis (SAPHO) syndrome is a rare disease that involves the skin, bones and joints. It is thought to be caused by infection with low-toxicity bacteria and to be the result of reactive infectious osteitis. However, this hypothesis has not yet been clearly established. New SAPHO syndrome treatment methods are needed because the disease does not respond to treatment in many cases. In this paper, a case is reported of SAPHO syndrome with pain in the acromioclavicular joint and with squamous and pustular macules on the palms and soles. First, the patient was treated with aceclofenac, prednisolon and sulfasalazine for two weeks. However, the symptoms were not relieved, so methotrexate and pamidronate were added to the treatment. Since no improvement was seen after four weeks of treatment, adalimumab was prescribed. The skin lesions were relieved two weeks later, and the bone pain and arthralgia, four weeks later. No recurrence or adverse effects were observed at the 22-week follow-up.

Background & Object: Ankylosing spondylitis (AS) is a chronic inflammatory disease that causes ankylosis and deformation of axial joints. Since current medicine cannot cure the disease yet, alleviating pain and preventing deformation with medications are the main therapy for patients with AS. The key medications for these purposes include nonsteroidal anti-inflammatory drugs (NSAIDs), and tumor necrosis $factor-{\alpha}$ ($TNF-{\alpha}$) inhibitors. This study aims to analyze prescribing patterns of AS patients in South Korea. Method: National Patients Sample data compiled by the Health Insurance Review and Assessment Service from 2013 was analyzed. Patients with AS were identified with Korean Standard Classification of Diseases code-6, which was M45. The rates of prescription, discontinuation, and switching ingredients were calculated for each medication during 2013. Results: Total number of patients was 655, and most of them were male (n = 514, 78.5%). Of all age groups, the proportion of 30-40 year old patients was the greatest (35.1%). The most utilized drug class was NSAIDs (82.4%). Less than half of patients were prescribed $TNF-{\alpha}$ inhibitors (n = 212, 32.4%). Meloxicam, aceclofenac, and celecoxib were the most frequently prescribed NSAIDs. In case of $TNF-{\alpha}$ inhibitors, adalimumab, etanercept and infliximab were the top three most prescribed drugs. Although not recommended by the current practice guideline, significant proportions of patients were identified using disease modifying anti-rheumatic drugs (DMARDs). Conclusion: Considering the current practice guideline and previous studies about the efficacy, the use of DMARDs should be reduced and medical insurance term in South Korea should be re-examined.

Background: Local anesthetics alone or in combination with adjuncts, such as oral medications, have routinely been used for pain control during endodontic treatment. The best clinical choice amongst the vast numbers of agents and techniques available for pain control for irreversible pulpitis is unclear. This network meta-analysis combined the available evidence on agents and techniques for pulpal anesthesia in the maxilla and mandible, in order to identify the best amongst these approaches statistically, as a basis for future clinical trials. Methods: Randomized trials in MEDLINE, DARE, and COCHRANE databases were screened based on inclusion criteria and data were extracted. Heterogeneity was assessed and odds ratios were used to estimate effects. Inconsistencies between direct and indirect pooled estimates were evaluated by H-statistics. The Grading of Recommendation, Assessment, Development, and Evaluation working group approach was used to assess evidence quality. Results: Sixty-two studies (nine studies in the maxilla and 53 studies in the mandible) were included in the meta-analysis. Increased mandibular pulpal anesthesia success was observed on premedication with aceclofenac + paracetamol or supplemental 4% articaine buccal infiltration or ibuprofen+paracetamol premedication, all the above mentioned with 2% lignocaine inferior alveolar nerve block (IANB). No significant difference was noted for any of the agents investigated in terms of the success rate of maxillary pulpal anesthesia. Conclusion: Direct and indirect comparisons indicated that some combinations of IANB with premedication and/or supplemental infiltration had a greater chance of producing successful mandibular pulpal anesthesia. No ideal technique for maxillary anesthesia emerged. Randomized clinical trials with increased sample size may be needed to provide more conclusive data. Our findings suggest that further high-quality studies are required in order to provide definitive direction to clinicians regarding the best agents and techniques to use for mandibular and maxillary anesthesia for irreversible pulpitis.

The purpose of this paper was to enable patients, who suffer from muscle damage. to return to their normal activities as soon as possible. With this in mind. this experiment was carried out to make an analysis of a variety of ingredients subjected to changes when muscle damage or muscle soreness was treated with aceclofenac, NSAID, and to find out what effect the anti-inflammation produced in relation to such symptoms. It made use of male rats (Sprague-Dawely) as subjects. It carried out two kinds of experiments: one was a preliminary experiment from March 15, 2001 to March 20, 2001 and the other was a main experiment from March 30, 2001 to April 15, 2001. Each group was composed of five rats. In case of DOMS. it worked with eight male adults from April 20. 2001 to April 30, 2001. It have come up with the following conclusions: 1. The leucocytes and erythrocytes of the experiment group were decreasing with the lapse of time in comparison with those of the contrast group. And a decrease in the number of hemoglobin had remarkably statistic significance (P<0.05). 2. Neutrophil, Lymphocyte and Monocyte decreased in 36, 24, 12 and 24 hours, respectively, which means that they had a significant difference(P<0.05). 3. CPK and LDH were reduced remarkably through the whole time slot in comparison with the contrast group, and had statistic significance(P<0.05). The findings above show that anti-inflammations cure bruises or damage or myalgia in a shorter period of time than the normal recovery of other treatment.

Polymer based physical mixtures or solid dispersions containing solubilizing compositions[OA, tween80 and SLS] were prepared using a spray-dryer. Lovastatin(LOS), simvastatin(SIMS), aceclofenac(AFC) and cisapride(CSP) were selected as poorly water-soluble drugs. Dextrin, poly(vinylalcohol) (PVA), poly(vinylpyrrolidone)(PVP) and polyethylene glycol(PEG) were chosen as solubilizing carriers for solid dispersions. The solid dispersions containing solubilizing compositions without drug were prepared without using organic solvents or tedious changes of formulation compositions. This system could be used to quickly screen the dissolution profiles of poorly water-soluble drugs by simply mixing with drugs thereafter. In case of solid dispersion containing drug, organic solvent systems could be used to solubilize model drugs. The dissolution rates of the drugs were higher when mixed with drug and solid dispersions containing solubilizing compositions. However, solid dispersions of LOS, AFC, and CSP simultaneously containing drug and solubilizing compositions in organic solvent systems were more useful than physical mixtures of drug and solid dispersions without drug except SIMS. Based on solubilizing capability of polymer based physical mixtures in gelatin hard capsules, optimal solid dispersion system of poorly water-soluble drugs could be formulated. However, it should be noted that dissolution rate of poorly water-soluble drugs were highly dependent on drug properties, solubilizing compositions and polymeric carriers.

Rat skin permeation of various nonsteroidal antiinflammatory drugs (NSAIDs) was investigated in vitro using Franz diffusion cell at $37^{\circ}C$. The effect of various skin permeation enhancers was also observed as a preliminary study of developing transdermal delivery systems of NSAIDs. Lipophilicity of NSAIDs was determined from thε partition coefficient (log P) in 1-octanol/water and 1-octanol/IPB mutual-saturated solutions. The solubility was determined in water, isotonic phosphate buffer (IPB), and propylene glycol (PG) at $37^{\circ}C$. The rat skin permeation rate of acetaminophen, piroxicam, and aceclofenac was almost negligible, although they were saturated in PG. Addition of 1 % permeation enhancer increased the permeation rate of ketoprofen, ketorolac, and diclofenac. However, the skin permeation rate of ibuprofen did not increase with the addition of various enhancers. Among the permeation enhancers testεd, oleic acid was the most effective for various NSAIDs. Based on the daily dose, lipophilicity, and the skin permeation ratε achieved in this study, ketoprofen and ketorolac seem to be the most promising drug candidates for transdermal delivery systems, especially when formulated with unsaturated fatty acids, such as oleic acid.

Objectives: Dry socket may occur secondary to the removal of any tooth. However, most dry socket cases develop in the third molar region. Dry socket is multifactorial in nature and has been treated using various modalities with varying success rates. This study assessed the efficacy of platelet rich fibrin (PRF) in established dry socket. Materials and Methods: Ten patients of either sex aged from 41 to 64 years with established dry socket according to established criteria were treated using PRF. Evaluation was performed by observing the reduction of pain using visual analogue scale, analgesic tablet use over the follow-up period, and healing parameters. Results: Pain was reduced on the first day in all patients with decreased analgesic use. Pain was drastically reduced during follow-up on the first, second, third, and seventh days with a fall in pain score of 0 to 1 after the first day alone. The pain scores of all patients decreased to 1 by the first day except in one patient, and the scores decreased to 0 in all patients after 48 hours. Total analgesic intake ranged from 2 to 6 tablets (aceclofenac 100 mg per tablet) over the follow-up period of 7 days. Healing was satisfactory in all patients by the end of the seventh day. Conclusion: PRF showed early pain reduction in established dry socket with minimal analgesic intake. No patients had allergic reactions to PRF as it is derived from the patient's own blood. PRF showed good wound healing. Our study suggests that PRF should be considered as a treatment modality for established dry socket.

DA-9601 is an extract obtained from Artemisia asiatica, which has been reported to have anti-inflammatory effects on gastrointestinal lesions; however, its possible anti-inflammatory effects on the small intestine have not been studied yet. Therefore, in this study, we investigated the protective effects of DA-9601 against the ACF-induced small intestinal inflammation. Inflammation of the small intestine was confirmed by histological studies and the changes in the CD4⁺ T cell fraction induced by the inflammation-related cytokines, and the inflammatory reactions were analyzed. Multifocal discrete small necrotic ulcers with intervening normal mucosa were frequently observed after treatment with ACF. The expression of IL-6, IL-17, and TNF-α genes was increased in the ACF group; however, it was found to have been significantly decreased in the DA-9601 treated group. In addition, DA-9601 significantly decreased the levels of proinflammatory mediators such as IL-1β, GM-CSF, IFN-γ, and TNF-α; the anti-inflammatory cytokine IL-10, on the other hand, was observed to have increased. It is known that inflammatory mediators related to T cell imbalance and dysfunction continuously activate the inflammatory response, causing chronic tissue damage. The fractions of IFN-γ⁺ Th1 cells, IL-4⁺ Th2 cells, IL-9⁺ Th9 cells, IL-17⁺ Th17 cells, and Foxp3⁺ Treg cells were significantly decreased upon DA-9601 treatment. These data suggest that the inflammatory response induced by ACF is reduced by DA-9601 via lowering of the expression of genes encoding the inflammatory cytokines and the concentration of inflammatory mediators. Furthermore, DA-9601 inhibited the acute inflammatory response mediated by T cells, resulting in an improvement in ACF-induced enteritis.
