Objectives : To determine whether the pragmatic acupuncture treatment provides more effective pain relief than treatment using the same acupuncture point to the all patients. Methods : We randomly allocated participants to treatment group 1 and 2. The group 1 is the pragmatic treatment group and the group 2 is using the same acupuncture point to the all patients. Primary outcomes were measured by the Western Ontario and McMaster Universities Osteoarthritis index(WOMAC) pain and function scores at 4, 8, and 14 weeks. Secondary outcomes were measured by 100mm VAS(Visual Analog Scale), ROM(Range of Motion) using Goniometer, and pain threshold using pressure algometer. Results : When patients were extension of the knee, they were statistically significant in improvement of the ROM in 14 weeks. Whole body condition and pain rate through VAS measurement were improved significantly in 14 weeks. Also pain score and function score of WOMAC were improved significantly in 14 weeks. We could get difference in pain score of two acupuncture groups significantly in 14 weeks. But we could not get difference in whole score of two acupuncture groups significantly. Local temperature using T.C thermometer was changed significantly in 14 weeks. But we could not get difference in whole score of two acupuncture groups significantly. Excluding above item, DITI, pain threshold, and ROM of the knee flexion were no difference in before and after treatment.

Objectives : Macrophage has an important innate defense role in the immune system. When we are infected with pathogens, macrophage ingests them through phagocytosis or endocytosis, and then secretes many cytokines, such as IL-1, IL-6 and $TGF{\alpha}$, which are regulators of immune responses. The aim of this study is to determine how Samjunghwan effects the expression of cytokine and other immune-related genes in macrophages. Methods : Cells were treated directly with Samjunghwan and/or LPS at regular intervals. Total RNA of cells was isolated using TRIzol reagent, and the changes in cytokine gene expressions were investigated using RT-PCR, western blot and ELISA. Results : $IL-1{\alpha},\;IL-1{\beta}$ and COX-2 genes were inducibly expressed specifically by Samjunghwan in macrophage. Especially, $IL-1{\beta}$ gene was induced most strongly by treatment with Samjunghwan. Over time, treatment with Samjunghwan showed that the expression levels of $IL-1{\alpha}\;and\;$IL-1{\beta}$ genes increased from 1 to 4h, and then decreased from 4 to ISh. However, the expression level of COX-2 gene increased continuously up to 11h. $IL-1{\alpha},\;IL-1{\beta}$ and COX-2 genes were expressed synergistically by a simultaneous treatment of both Samjunghwan and LPS in macrophages. Secretion levels of translated $IL-1{\beta}$ increased continuously up to 11h. Conclusions : Though this study is only a start in the investigation of the efficasy of Samjunghwan, these results suggest that Samjunghwan has positive effects on immune responses.

Resveratrol, a phytoalexin found at high levels in grapes and in grape products such as red wine, has been reported to possess a wide range of biological and pharmacological activities including anti-oxident, anti-inflammatory, anti-mutagenic, and anti-carcinogenic effects, but its molecular mechanism is poorly understood. In this study, we examined the effects of resveratrol on lipopolysaccharide (LPS)-induced growth inhibitory activity and cell growth-regulatory gene products in astroglioma C6 cells to elucidate its possible mechanism for anti-cytotoxicity. It is shown that LPS induced time-dependent growth inhibition and morphological changes of C6 cells, which were recovered by pre-treatment with resveratrol. The anti-proliferative effect of LPS was associated with the induction of tumor suppressor p53 and cyclin-dependent kinase (Cdk) inhibitor p21 (WAF1/CIP1) expression assessed by RT-PCR and Western blot analysis in time-dependent manner in C6 cells. In addition, the pro-apoptotic Bax expression was also up-regulated in LPS-treated C6 cells without alteration of anti-apoptotic Bcl-2 and Bcl-XL expression. However, resveratrol significantly inhibited LPS-induced p53, p21 and Bax levels, suggesting that the modulation of p53, p21 and Bax levels could be one of the possible pathways by which resveratrol functions as anti-cytotoxic agent.

Objectives: This review aimed to investigate the effectiveness of Chai-Hu-Shu-Gan-San (CHSGS) for treatment of insomnia. Methods: 9 databases were comprehensively searched from their inception dates until Jan 2020 using keywords like Insomnia, Chai-Hu-Shu-Gan-San and Sihosogan-san. We included randomized controlled trials (RCTs) using CHSGS as the main intervention for insomnia patients. We assessed the quality of RCTs using the Cochrane risk of bias tool and Jadad scale. Results: 5 RCTs were included. The Chinese classification of mental disorders -3 (CCMD-3) was the most frequently used diagnostic criteria. The effective rate was the most frequently used as outcome. All the 5 RCTs that reported CHSGS and CHSGS adjunctive therapy on insomnia were more effective compared to western medication. Only one study reported adverse effects. The methodological quality of the included RCTs were generally poor. Conclusions: This review found that CHSGS may be effective to treating insomnia. However, because of the small number, heterogeneity and very low methodological quality of included studies, we could not draw any definitive conclusions. Therefore, more rigorous randomized control studies are warranted.

Objective：The Herbal Remedy for Diabetes Mellitus-01 (HRDM-01) is composed of 11 species of medicinal plants. HRDM-01 is used as anti-hyperglycaemic agent. Anti-hyperglycaemic agents in western medicine often have hepatotoxicities. Therefore, we investigated safety of HRDM-01, especially in liver functions. Methods：We investigated the effects of HRDM-01 on liver function measuring serum AST, ALT and LDH levels and histopathological changes of liver tissue using photomicroscope. In addition, we also investigated the effects on serum lipid levels such as total cholesterol, HDL-cholesterol and triglyceride. Results：In our experiment, single injection of streptozotocin elevated levels of AST and ALT in serum. But LDH level was not affected. In addition, our animal model showed elevated levels of total cholesterol and triglyceride in serum. 30 days treatment with HRDM-01 lowered serum AST level. Serum levels of ALT and LDH did not affected. In addition, HRDM-01 lowered serum triglyceride level significantly. In histopathological observation, we did not find any abnormal changes in all experimental groups. Conclusions：Briefly, HRDM-01 did not elevate serum levels of ALT, LDH, total cholesterol and did not affect histopathological changes in liver tissues. Moreover, HRDM-01 lowered serum AST, triglyceride, which are elevated by induction of diabetes mellitus. These results suggest the safety of HRDM-01 in diabetic treatment.

Objectives : Recent etiological studies show that oxidative stress might play a major role in the diabetes and its complications. Mori Ramulus (MR) has been known to have antioxidative, anti-inflammatory and antidiabetic effects. The methanol extract of MR was tested for its effectiveness in LLC-PK1 cells exposed to high glucose. Methods : The cytoprotective effect of MR was evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The antioxidative effect was measured in terms of generation amount of ${\cdot}O_2^-$ by 2',7'-dichlorodihydrofluorescein diacetate (DCFDA), NO by 4,5-diaminofluorescein (DAF-2), $ONOO^-$ by dihydrorhodamine 123 (DHR 123) in the high glucose -treated LLC-$PK_1$ cells. Western blotting was performed using anti-AGE, anti-RAGE, anti-MAPKs(ERK1/2, JNK, p38), anti-PI3K, anti-Akt, and anti-NF-${\kappa}$B (p50, p65) respectively. Results : MR extract reduced cell death and inhibited the generation of ${\cdot}O_2^-$, NO, $ONOO^-$ in the high glucose-treated LLC-$PK_1$ cells. MR inhibited the expression of AGE, RAGE, MAPKs, PI3K, and Akt by means of decreasing NF-${\kappa}$B activation. MR also inhibited NF-${\kappa}$B activation itself. Conclusions : These results indicate MR has cytoprotective, antioxidative, and anti-inflammatory effects. Therefore it is suggested that MR might prevent and cure diabetes and its complications.

We demonstrate that magnolol, a hydroxylated biphenyl compound isolated from Magnolia officinalis, inhibits LPS-induced expression of iNOS gene in RAW 264.7 cells(murine macrophage cell line). Treatment of RAW 264.7 cells with magnolol inhibited LPS-stimulated nitric oxide production in a dose-related manner. RT-PCR analysis showed that the decrease of NO was due to the inhibition of iNOS gene expression. Western immunoblot analysis of phosphorylate p38 kinase showed magnolol significantly inhibited the phosphorylation of p38 kinase which is important in the regulation of iNOS gene expression. The specific p38 inhibiter SB203580 abrogated the LPS-induced NO generation and iNOS expression, whereas the selective MEK-1 inhibitor PD98059 did not affect the NO induction. Immunostaining of p65 and reporter gene assay showed that magnolol inhibited NF-${\kappa}/Rel$ nuclear translocation and transcriptional activation, respectively. Collectively, this series of experiments indicates that magnolol inhibits iNOS gene expression by blocking NF-k/Rel and p38 kinase signaling. Due to the critical role that NO release plays in mediating inflammatory responses, the inhibitory effects of magnolol or iNOS suggest that magnolol may represent a useful anti-inflammatory agent.

Objectives : Recently there have been encouraging results, from a western perspective, in the cancer research field regarding the anticancer effects of herbal medicine. This paper was aimed to review herbal medicine playing its anticancer role in terms of apoptosis, inflammation control, differentiation and telomerase. Methods : New studies for tang, medicinal herb itself or effective ingradients of medicinal herb showing anti-cancer effectiveness were reviewed and summarized in terms of pharmacological action. Results : Ethanol extracts of $Spatholobus$ $suberectus$ greatly inhibited cancer cell growth inducing cell apoptosis and cytotoxic effects. $Scutellaria$ $baicalensis$ may be responsible for its anticancer activity showing inhibition of $PGE_2$ synthesis via suppression of COX-2 expression. Saikosaponins isolated from $Bupleurum$ induced the differentiation of C6 glioma cells, cancer cells, into astrocytes, normal cells. Acetone extract of $Bupleurum$ $scorzonerifolium$ inhibited proliferation of human lung cancer cells via inducing apoptosis and suppressing telomerase activity. Conclusions : Herbal medicine inhibited cancer cell growth inducing cell apoptosis and cytotoxic effects. Inflammation persisting for a decade eventually elevates the risk of cancer sufficiently that it is discernible in case control epidemiological studies. Differentiation therapy is defined as a therapy to treat cancers by inducing differentiation of the stem cells. Telomerase expression is a hallmark of cancer. Nearly the complete spectrum of human tumors has been shown to be telomerase positive.

목적 : 퇴행성 관절염은 염증성 사이토카인인 IL-$1\beta$에 의해 연골관절이 파괴되고 이로 인해 염증성 사이토카인이 더욱 증가하는 질환이다. 퇴행성 관절염을 치료하기 위해서는 연골 파괴를 가속화시키는 catabolic cytokines의 활성을 줄이고, 성장인자인 anabolic factor의 활성을 증가시는 연골 보호 작용이 있어야 한다. 본 연구에서는 독활 승마 처방(OAH19T)이 catabolic/anabolic 대사 조절에 어떤 영향을 미치는지와 그 신호 전달 기전에 대해 연구하였다. 또한 OAH19T를 구성하는 단미재 및 임상에서 사용되는 COX-2 inhibitor인 Celebrex(CEL)와 효능을 비교 실험하였다. 방법 : 배양된 세포에 IL-$1\beta$로 자극한 후 (1) glycosaminoglycan(GAG)의 분해 억제 정도, (2) OAH19T와 CEL에 대하여 MMP-1과 MMP-3의 유전자 발현 및 활성 억제, (3) Aggrecan 및 Aggrecanases의 유전자 발현 및 활성 억제, (4) OAH19T의 growth factor의 조절 능력, (5) MAPK pathway 등을 RT-PCR(reverse transcriptase-polymerase chain reaction), ELISA(Enzyme-linked immunosorbent assay), western blot, viability 측정을 통해 검증했다. 결과 : 사람 관절 세포에서 (1) 독활 승마 각각의 단미재, 임상에서 사용중인 셀레콕시브(CEL), 조인스보다 실험 약물(OAH19T)이 저농도에서 GAG 분해 억제 효과가 우수하였고, 부탄올로 분획한 OAH19B와는 동등한 효과를 보였다. (2) OAH19T는 IL-$1\beta$에 의하여 활성화된 MMP-1과 MMP-3의 발현을 모두 억제하였으나, CEL은 MMP-1의 발현은 억제하였으나 MMP-3의 발현은 억제하지 못하였다. (3) OAH19T는 IL-$1\beta$에 의하여 손상된 Aggrecan을 회복시켰으며 이는 활성화된 Aggrecanase-1과 Aggrecanase-2를 억제시킴으로써 나타난 결과이다. 그러나 CEL의 경우, 손상된 Aggrecan을 회복시키지 못하였다. (4) 배양된 세포는 IL-$1\beta$에 의하여 TGF-$\beta$II및 TGF-$\beta$ receptor II의 발현이 억제되었으나, OAH19T는 TGF-$\beta$II및 TGF-$\beta$ receptor II의 발현을 회복시켜 OAH19T가 anabolic한 조절능력이 있음을 시사한다. 그러나 CEL의 경우 growth factor에 대한 조절 능력이 없었다. (5) 대사 조절 작용에 대한 기전으로서 MAPK pathway에 대해서 연구한 결과 IL-$1\beta$에 의하여 유도된 pERK, pp38 kinase의 활성은 억제하였고, pJNK의 활성은 변하지 않았다. 또한 OAH19T는 연골 세포에 독성이 없었으며 IL-$1\beta$에 의해 유도된 세포 증식만을 억제시켰다. 이 결과로, OAH19T가 OA chondrocyte의 탈분화 및 세포 고사를 억제하여 연골보호 및 회복 효과가 있음을 알 수 있었다. 결론 : OAH19T는 이를 구성하는 단미재 및 CEL보다 연골보호 효과가 월등하였고, 이러한 연골보호 효과는 catabolic cytokines/growth factors의 균형으로 대사조절을 통해 연골세포의 탈분화 및 세포 고사를 억제하여 연골보호 및 회복 효과가 있음을 알 수 있었다.
