Objectives : The purpose of this study is to investigate the preventive and therapeutic efficacy of osteoarthritis using a Yeonsan-Ogye egg. so, we researched at effects of Yeonsan-Ogye egg extract on MIA-induced Osteoarthritis animal models. Methods : Yeonsan-Ogye egg extract was administered 500 mg/kg/day, 1000 mg/kg/day and 2000 mg/kg/day to SD-Rat for 2 weeks. After that, osteoarthritis was induced with $60mg/m{\ell}$ of monosodium iodoacetate (MIA) and futher administration was continued for 4 weeks. 3D imaging of cartilage patella were obtained using a Micro-CT system and the pathology change of knee was observed by H&E and safranin-O staining. The weight bearing ratio was measured by incapacitance test meter. MMP-2, MMP-9, COMP, CTX II, calcitonin and glycosaminoglycan level in serum were measured using a ELISA. Results : Micro-CT and Histopathological analysis showed the volume of the patella cartilage and the proteoglycan contents were increased in all groups. also weight bearing ratio was decreased in all groups compared with control group. Calcitonin production was increased in and 2000 mg/kg/day group and glycosaminoglycan production was increased in all groups. In addition, MMP-2, MMP-9, COMP and CTX II production were decreased in 1000 and 2000 mg/kg/day groups respectively in comparison with control. Conclusions : The results for Yeonsan-Ogye egg showed prevention and treatment efficacy against arthritis at serum and the cartilage. These results may be used a remedy for new korea medicine to ease the symptoms mentioned above. also, suggest that Yeonsan-Ogye egg can be used preventive and therapeutic material for osteoarthritis.

Objectives: This study aims to investigate the effects of diabetes mellitus care mixture (DCM) on blood glucose and lipid metabolism in type 2 diabetic mellitus mice. DCM consisted of lagerstroemia speciose, allium hookeri, momordica charantia, amaranthus tricolor, and boesenbergia rotunda, which have been proven to have antidiabetic properties. Methods: In this study, we researched the effects of DCM in type 2 diabetic mellitus mice. C57BLKS/J mouse groups had no treatment, db/db mouse randomly assigned to 2 groups, and treated with distilled water and DCM (200 mg/kg/day). Blood glucose levels and body weight were checked every week. After 4 weeks of treatment, liver function indicators (AST, ALT, and LDH) and lipid metabolites (triglyceride, total cholesterol, LDL-cholesterol, HDL-cholesterol) were measured with a biochemistry analyzer. Diabetic factors (insulin, resistin, and leptin) were measured with ELISA. Results: DCM was decreased blood glucose, diabetic factors, liver function indicators, triglyceride, total cholesterol, and LDL-cholesterol significantly. Also, HDL-cholesterol was significantly increased in DCM group. The bodyweight of DCM group decreased but, no significant difference with the control group. DCM may have the potential to improved diabetes mellitus by regulating blood glucose levels and diabetic factors. Also protecting from diabetic complications by adjusting liver function indicators and lipid metabolites. Conclusions: These results suggest that DCM to be used as an oriental medicine for diabetes, the results of clinical trials are needed.

The purpose of this study is to examine the antioxidant effect of hamyang wild-simulated ginseng and ginseng berry complex(HGC) and to investigate the mechanism of anti-inflammatory effect on macrophage cell line (RAW264.7 cells). For antioxidant activity of HGC was measured by total polyphenol contents were estimated with folin-ciocalteu method, and total flavonoid contents were estimated with aluminum chloride methods. And, assessed with 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid (ABTS) radical scavenging activity assay. MTT assay was performed to determine the effect of HGC on cell viability in RAW264.7 cells. In addition, anti-inflammatory effect of HGC was investigated in RAW264.7 cells. RAW 264.7 cells, in which an inflammatory response was induced by lipopolysarccharide (LPS), were treated with HGC, and nitric oxide production was measured by griess assay. And protein expression level of inflammatory cytokine and phosphorylation of MAPK signaling pathways were confirmed by western blot analysis. Total polyphenols and flavonoids contents in HGC were quantified, and increased DPPH and ABTS radical scavenging activity in a concentration-dependent manner was confirmed. In addition, HGC was significantly inhibited nitric oxide (NO) production and inflammatory cytokine (iNOS, IL-1β, IL-6, and TNF-α) expression in LPS-stimulated RAW264.7 cells. Also, HGC was significantly inhibited the phosphorylation of MAPK signaling pathways. These results suggest that HGC can be used as effective herbal medicine extract for antioxidant and anti-inflammatory effect. As a result, it is thought that HCG can be used as a functional material effective for antioxidant and anti-inflammatory effects. And it will be possible to promote industrialization using hamyang wild-simulated ginseng and ginseng berry, and to increase high-value-added.

The purpose of this study was to investigate the antioxidant and hangover cure effects of compound prescription containing Phyllanthus emblica and Azadirachta Indica leaf extract (CP). In vitro experiments, HepG2 cells were induced oxidative stress by hydrogen peroxide (H2O2) and treated with CP at 50, 100, 200 ㎍/㎖ concentration. Antioxidant enzyme (superoxide dismutase (SOD), catalse (CAT), glutathione peroxidase (GPx), glutathione reductase (GR) activity and glutathione (GSH) content were decreased by hydrogen peroxide-induced oxidative stress, but CP was increased that. In vivo experiments, experiment rats were orally administered alcohol 3 g/kg and, after 30 min administered CP 200 ㎎/㎏. After 1 and 3 h of alcohol administration, blood was collected from the tail vein, while after 5 h, blood was collected from the heart. CP modulates alcohol dehydrogenase (ADH) and acetaldehyde level, thereby decreased alcohol level in serum. Also, CP decreased the levels of aspartate aminotransferase (AST) and alkaline phosphatase (ALP). These results suggest that CP has antioxidant effects and alleviates alcohol hangover symptoms.

The purpose of this study was to investigate the effects of natural herb mixture containing Laminaria japonica Areschoung (LAM) on fine dust-induced bronchitis in mice. Laminaria japonica Areschoung is main content of LAM, which is including fucoidan. Fucoidan extracted from phaophyta is known to prevent bronchitis and to defend against bacteria and virus infection. In this study, we experienced the effect of LAM on bronchitis and investigated gene expressions (e.g ; IL-8, COX-2, MCP-1) and bio-markers (e.g ; IL-8, PGE2, MUC5AC) associated with bronchitis by using A549 cells. Also, we investigated whether LAM can suppress the bronchitis in fine dust-induced animal models. We injected fine dust (50 ㎕) twice as INT (Intra-Nasal-Trachea) method. Then LAM (200 ㎎/㎏ and 400 ㎎/㎏) were oral administered for 14 days. We analyzed the number of immune cells, immunoglobulin E, bio-markers level associated with bronchitis. LAM significantly decreased bio-marker (IL-1β, IL-6, IL-8, TNF-α, Histamine, PGE2), immune cells (white blood cell, neutrophil, lymphocyte, monocyte), and immunoglobulin E, that are increased by fine dust. Taken together, this study suggest that LAM can be used as effective herbal extract for bronchitis.

Objectives : Coronary and cerebrovascular disease with high mortality is a major factor in arteriosclerosis. Pro-inflammatory cytokines damage vascular endothelial cells, leading to vascular inflammation. These vascular inflammation can build up cholesterol and thrombus to cause atherosclerosis. Methods : In this study, we researched the effect of ChungHyul-Plus for vascular inflammation in human umbilical vein endothelial cells (HUVECs) stimulated with tumor necrosis factor-α (TNF-α). Change in mRNA expression of inflammatory cytokines (CCL5, CXCL8, CX3CL1, and MCP-1), cell adhesion molecules (VCAM-1 and ICAM-1), and anti-inflammation modulators (KLF2 and eNOS) were quantified by qRT-PCR. Results : ChungHyul-Plus decreased expression of inflammatory cytokines and cell adhesion molecules and increased anti-inflammation modulators expression in TNF-α stimulated HUVECs. Conclusions : These results suggest that ChungHyul-Plus can be used in the treatment and prevention of vascular inflammation and arteriosclerosis.
