A clinical trial was made on 76 patients with pulmonary tuberculosis to determine the effectiveness and acceptibility of 6 month 2SHRZ/4HR antituberculosis regimen. Out of 76 patients, 13 patients (17.1%) dropped out and 11 patients (14.5%) were excluded due to drug resistance. In 3 patients (3.9%), regimen was changed due to adverse effects. Treatment failure rate was 2.0% in 50 patients. One patient, who had far advanced lesion, was treated longer than 6 months due to failure of sputum conversion. The most common adverse effect was arthralgia, which was controlled by the administration of allopurinol and nonsteroidal anti-inflammatory drug. In conclusion, 2SHRZ/4HR for 6 months was effective regimen in treating the newly-diagnosed patients with tuberculosis, but change of the regimen and duration might be carefully considered by the severity of the lesion and adverse effect of the drug But further study will be needed to evaluate not only the efficacy and efficiency of 6 month chemotherapy but also relapse rates.

A new liquid chromatographic chiral stationary phase based on (2S,3S)-O,O'-bis-(10-undecenoyl)-N,N'-bis-(3,5-dinitrobenzoyl)-2,3-diamino-1,4-butandiol was prepared starting from (2R,3R)-1,4-bis(benzyloxy)-2,3-butanediol. The new chiral stationary phase was applied to the resolution of racemic anilide derivatives of N-acetyl-a-amino acids, 1,1'-bi-2-naphthol and 3,3'-diaryl-1,1'-bi-2-naphthols. The CSP was also applied to the resolution of some chiral drugs including a diuretic, bendroflumethiazide, and non-steroidal anti-inflammatory agents such naproxen and alminoprofen. In every case, the chiral recognition efficiency of the new CSP was quite excellent.

There is a growing consumer preference for self-medication, which has resulted in the growth of the Korean functional food market to \1.5 trillion in 2014. Functional foods that can modulate immune responses and enhance liver health are in the top 2 product-specific health functional food categories. The aim of this project was to develop and commercialize new health functional foods incorporated with Cordyceps militaris. Cordyceps genus includes about 400 species, many of which have been used as traditional medicines for many years in Asian countries. C. militaris belongs to the class Ascomycetes and has been used extensively as a crude drug and tonic food in East Asia. Owing to the various physiological activities of its main active constituent, cordyceptin, C. militaris is currently being used for multiple medicinal purposes. Recently, many studies have tried to elucidate the pharmacological mechanisms underlying the activities of Cordyceps spp., which include immune activation, anti-inflammatory, anticancer, and antiviral effects. After continuous attempts and research toward industrialization, C. militaris cultivated using brown rice was developed into a product by a standardized process and mass-cultivating system. It was successfully introduced into the market and was approved as a functional food ingredient for the first time in Korea. Based on this information, C. militaris containing functional food product for strengthening the immune system was released in August 2014 under the brand name "Dongchoong Ilgi." Dongchoong Ilgi is potentially beneficial for improving immune and liver functions and may enhance both the convenience and effectiveness of health functional foods taken by healthy people and patients with minor illness. In addition, the results of our study may be applicable for the development of health functional foods that could lower the risk of diseases such as the common cold and cancer.

The effect of acteoside, a phenylpropanoid glycoside isolated from Clerodendron trichotomum Thunberg, on histamine and arachidonic acid release was investigated in RBL 2H3 cells. Histamine was dose-dependently released from RBL 2H3 cells by melittin, arachidonic acid and thapsigargin. In extracellular $Ca^{2+}-free$ solution, basal secretion of histamins increased by two fold. The response of histamine release to melittin and thapsigargin in $Ca^{2+}-free$ solution was significantly decreased, whereas the response to arachidonic acid was significantly increased as compared with those in normal solution. Acteoside inhibited histamine release induced by melittin, arachidonic acid and thapsigargin in a dose-dependent manner in the presence or absence of extracellular $Ca^{2+}$. However, the inhibitory activity of acteoside was more potent in normal solution than that in $Ca^{2+}-free$ solution. These data suggest that inhibitory mechanism of acteoside on histamine release may be related to extracellular $Ca^{2+}$. On the other hand, acteoside significantly inhibited arachidonic acid release and prostaglandin $E_2$ production Induced by $0.5\;{\mu}M$ melittin. It is possible that acteoside may be developed as an anti-inflammatory agent.

Objectives : Mahuang-Chuanwu(Mahwang-Cheonoh) Pharmacopuncture(MCP) has been used to treat obesity in Clinical Korean Medicine. MCP solution(MCPS) is also expected to have strong anti-obesity activities. However, little is known about the mechanisms of its inhibitory effects on adipocyte differentiation and lipogenesis. Methods : In the present study, we examined the effects of MCPS on differentiation and lipogenesis of 3T3-L1 adipocytes. To elucidate the mechanism of the effects of MCPS on lowering lipid content in 3T3-L1 adipocytes, we examined whether MCPS modulates the expressions of transcription factors to induce lipogenesis and adipogenic genes related to regulate the accumulation of lipids. Results : Our results showed that MCPS significantly inhibited differentiation and lipogenesis of 3T3-L1 adipocytes in a dose-dependent manner. MCPS suppressed the mRNA expressions of cytidine-cytidine-adenosine-adenosine-thymidine(CCAAT)/enhancer binding proteins ${\alpha}$($C/EBP{\alpha}$), C/EBP ${\beta}$, $C/EBP{\delta}$, and peroxisome proliferator-activated receptor ${\gamma}$($PPAR{\gamma}$) genes related to the induction of adipose differentiation. MCPS inhibited the mRNA expressions of adipose-specific aP2, adipsin, lipoprotein lipase(LPL), CD36, TGF-${\beta}$, and leptin genes related to the fat formation. MCPS downregulated the mRNA expressions of liver X receptor(LXR) ${\alpha}$ and fatty acid synthase(FAS) genes related to the induction of lipogenesis. In addition, MCPS reduced the production of adipocyte-induced pro-inflammatory cytokines. Conclusions : MCPS could regulate the accumulation of lipids and expression of adipogenic genes via inhibition of transcript factors related to induction of adipose differentiation.

This study was performed to investigate the effects of Shigyungbanha-tang(SGT) on the lipopolysaccharide(LPS) induced acute lung injury(ALI) in mice. 1 and 24 h before LPS intratracheal instillation, control group was taken distilled water orally. Treated groups was taken each concentrate SGT(2.5 g/kg, 6.7 g/kg) by orally as same times. Normal group was not instilled with LPS and was taken distilled water. 24 h after LPS intratracheal instillation, lung histology was performed in inflated-fixed lungs in 3 mice of each groups. The other mice of each groups, bronchoalveolar lavege fluids(BALF) was obtained to measure proinflammatory cytokines(TNF-$\alpha$, IL-$1{\beta}$, IL-6) and blood sample was obtained to measure white blood cell(WBC). In vitro, the effect of SGT($100\;ug/m{\ell}$, $500\;ug/m{\ell}$, $1000\;ug/m{\ell}$) on the release of RANTES, TARC induced by TNF-$\alpha$ and IL-4 in human alveolar epithelial cell(A549) was examined. Histopathologically, SGT prevented LPS-induced lung injury. SGT decreased protein, TNF-$\alpha$, IL-$1{\beta}$ and IL-6 according to concentrations. In vitro, $500\;ug/m{\ell}$, $1000\;ug/m{\ell}$ concentrate SGT suppressed the expression of RANTES and TARC on A549 cells. On the basis of these results, SGT had a markedly anti-inflammatory effect in a clinically relevant model of ALI. Nevertheless, further investigations are required to determine the potential clinical usefulness of SGT in the adjunctive therapy of ALI.

Acute transverse myelitis(ATM) is defined as an acute intramedullary dysfunction of the spinal cord, ascendng or static involving both halves of the cord and appearing without any history of previous neurological diseases due to traumatic accident, tumor of all kind, encephalitis and of course excluding all possible viral, bacterial and fungal infection. It is mainly characterized by acute motor disorder of both limbs in respect to which spinal segments are affected as well as sensory disorder and dysuria & dyschezia. The exact cause is unknown, however it is recently suggested that immunological factors are highly involved. It has been reported by several reliable sources that it is often accompanied by immunological diseases such as systemic lupus erythematosus(SLE). As treatments non steroid anti-inflammatory drugs(NSAIDS) are primarily recommended as to steroids, limited doses are injected only with the proper prescription from the physician. Operative methods are not options as traumatic accidents and tumors are excluded as factors. To enhance muscle strength and prevent articular contracture physical therapy and passive exercise is imperative. The following patient whose chief complaints were mainly about hypoesthesia of Rt. lower limb and stiffness of phalanges of both fingers as well as to weakness of lower extermity. Therefore it has been diagnosed as arthalgia syndrome. In oriental medicine factors such as wind evil heat-evil, dampness-heat evil, cold evil cause the arthalgia syndrome. In this case the patient was diagnosed as dampness-heat evil and herbal medicine Chunglijagam-Tang and Dong-Qi acupuncture was applied to treat bladder disorder.

Application of membranes for guided tissue regeneration(GTR) have been confined to the subgingival barrier functions; however, many studies have provided evidence that some drugs, including tetracycline, initially can promote the growth of periodontal ligament or alveolar bone in peridontal therapy. Osseous regeneration in periodontal defects is increased by local administration of tetracycline due to its anti-collagenolytic effect, which enhances bone-forming ability via osteoblast cell chemotaxis and reduced bone resorption. The aim of this study was to evaluate effects of tetracycline loaded poly-L-lactide(PLLA) barrier membranes for guided bone regenerative potential. Tetracycline was incorporated into the PLLA membrane with the ratio 10% to PLLA by weight. Ability to guided bone regeneration of the membranes were tested by measuring new bone in the tibial defects($7{\times}10{\times}5\;mm^3$) of the beagle dog for 4,5, and 6 weeks. In control, drug-unloaded PLLA membranes were used in same size of defect. In histologic finding of the defect area, a few inflammatory cells were observed in both groups. These membrane were not perforated by connective tissue and maintained their mechanical integrity for the barrier function for 4-6 weeks. New bone formation was greater in defects covered by tetracycline-loaded membrane than in defects covered by drug- unloaded membranes. In bone regeneration guiding potential test, tetracycline-loaded membrane was more effective than drug- unloaded membranes(p<0.05). These results suggest that tetracycline-loaded PLLA membranes potentially enhance guided bone regenerative efficacy and might be a useful barrier for GTR in periodontal treatment.
