  • The effect of water extract composed of panax ginseng radix rubra, acanthopanacis cortex, and cordyceps (PAC) on diabetic animal models were investigated in two different diabetic animal models. FAC water extract significantly reduced the plasma glucose levels on day 30 as compared with the diabetic control group in $KKA^Y$ obese, hyperglycemic and hyperglycemic and hyperinsulinemic mice, and also reduced the plasma glucose levels as well as total cholesterol in multiple low dose (MLD) strep tozotocin-induced diabetic SD rats. PAC water extract also showed an inhibitory effect on reduction of body weight and on development of MLD STZ-induced diabetic state. Elevated kidney hypertrophy, which is a characteristic feature shown in early stage of diabetic nephropathy and calculated as the ratio of kidney mass (g) relative to the body weight (g), was also markedly improved in PAC water extract- treated group as compared to the diabetic control group. Taken together, these data suggest that PAC water extract may have a potential as a antidiabetic agent in type 2 diabetes mellitus.

  • In Northeast Asia, Paeoniae Radix has been used in treatments of inflammation-causing diseases such as arthritis for many centuries. Paeoniflorin, one of the principle bioactive monoterpene glucosides from the paeony root, is reported to be mostly responsible for the effectiveness of the treatments. However, the anti-inflammatory effect of a monoterpene, paeoniflorigenone (PFG) which partially has the moiety of paeoniflorin minus a glucose structure is unknown. Thus, the aim of this work was to investigate anti-inflammatory activity of PFG. For the investigation, PFG activity on the NO (nitric oxide) production from LPS-stimulated macrophages, and the anti-inflammatory effect was tested in the animal model of septic arthritis caused by Candida albicans, a major etiological agent for septic arthritis. For induction of the arthritis, mice were administered with an emulsion of C. albicans cell wall (CACW) mixed with Complete Freund's Adjuvant (CFA) via footpad-injection (Day 0); PFG at a dose of 0.5 or 1 mg/mouse (25 or 50 mg/kg of body-weight) was given to the animals on Day 3, 6, and 9; footpads were scored for arthritis. Moreover, the PFG effect on proliferation of T-lymphocyte that causes aggravation of arthritis was additionally tested. Data resulting from those tests showed that PFG inhibited the NO production from the stimulated macrophage in a dose dependent manner (P<0.05), indicating that PFG is an anti-inflammatory. To confirm the in-vitro results, anti-inflammatory activity of PFG was determined against C. albicans-caused septic arthritis. Data showed that PFG-treatment reduced footpad-swelling which indicates that PFG has anti-arthritic effect (P<0.05), which is therapeutic. The anti-arthritic effect appeared to be mediated by PFG suppression of T-cell proliferation. Ultimately, PFG, a monoterpene component, has anti-inflammatory activity analogous to paeoniflorin. The anti-inflammatory activity treats the septic arthritis due to a pathogenic fungus C. albicans.

  • Objectives : The purpose of this study was to confirm whether Codonopsis Radix(CR) could be used in the same way for expected indications or diseases of adaptation instead of Ginseng Radix(GR), which acts as a principal herb in Sagunja-tang. Methods : The Traditional Chinese Medicine Systems pharmacology(TCMSP), a database for the study of systems biology related to Chinese medicine, screened potential active compounds in each quartet. By searching for all the proteins that each compound provides, the target of Sagunja-tang with GR(GRST) and the target of Sagunja-tang with CR(CRST) were compared using the network analysis method, and the top ranked target of each serving was selected. Results : Through TCMSP, a Chinese medicine database, the potential effective ingredients of GRST or CRST screened, and the target proteins related to these substances were found to be the most affected by Glycyrrhizae Radix et Rhizome, an herbal medicine mixed in Sagunja-tang, and the target diseases were the same. And the same were found for the target protein, gene and target diseases of GRST and CRST. Conclusions : The prescription with similar composition is likely to have similar network pharmacology analysis results, and the analysis result may be controlled by the herbal medicines which are assumed to be the main function. Therefore, rich and reproducible basic studies is more important because network pharmacological studies can be dominated by data that has been done a lot of previous studies.

  • Objectives : Traditional medicines isolated from natural products often have positive effects in the prevention and healing of various immune disorders, such as allergy and atopic inflammation. Scrophulariae Radix (SR) been used in oriental medicine used for treatment of acute and chronic inflammatory diseases. Mast cells are known to play important roles in the initiation of allergic reactions. In this study, we investigated the effects of SR ethanol extract on inflammatory responses in IgE-stimulated RBL-2H3 mast cells. Methods : Rat basophilic leukemia RBL-2H3 cells were purchased from Korean Cell Line Bank (KCLB No. 22256). Cell viability was measured by MTT assay. Assays for ${\beta}-Hexosaminidase$ Secretion : RBL-2H3 cells were sensitized with dinitrophenyl-ImmunoglobulinE (DNP IgE). The next antigen DNP-BSA ($25ng/m{\ell}$) was added for 10 minutes and the reaction was terminated after 5 minutes in the ice bath. To determine ${\beta}-Hexosaminidase$ release, supernatants were aliquoted into 96-well plates. Samples were mixed with substrate solution and incubated for 1 h at $37^{\circ}C$. Absorbance was measured with a spectrophotometer at 405 nm. IL-4 and tumor necrosis $factor-{\alpha}$($TNF-{\alpha}$) concentrations in cell culture supernatants were measured using enzyme-linked immunosorbent assay (ELISA) kits. Results : The cytotoxicity of SRE in RBL-2H3 cells was less than 5%. SRE inhibited DNP-IgE-imduced degranulation of mast cells in RBL-2H3 cells. Also significantly decreased the levels of inflammatory cytokine, IL-4 and TNF-alpha. In this study, the SRE showed potential anti-allergic and antiinflammatory. Conclusions : These results indicate that SRE could be inhibit the allergic response through suppressing the mast cell activation.

  • We compared the hypoglycemic effects of Ginseng Radix Alba (GRA) and Mori Folium (MF) in multiple low dose (MLD) streptozotocin(STZ)-induced diabetic rats. In order to induce hyperglycemic state 25 mg/kg of STZ was injected intraperitoneally for 5 consecutive days. SD rats were randomly divided into diabetic control and treatment groups. Treatment groups were administered with either 500 mg/kg of GRA (G500), 500 mg/kg of MF (M500), or 250 mg/kg of GRA mixed with same dose of MF (GM250) for 3 weeks. Blood glucose level and body weight were measured every 5th day. G500 and M500 both significantly reduced blood glucose levels as compared to the diabetic control group (diabetic control, 458.3$\pm$25.4 mg/dl; G500, 275.0$\pm$12.0; M500, 278.0$\pm$15.4; GM250, 324.0$\pm$18.4). While body weight in diabetic control group was decreased slightly after 3 weeks, treatment groups showed gradual increases of body weight during 3 week-period. Plasma insulin level was increased by treatment with GRA, but those levels in M500 and GM250 groups were similar to the diabetic control (normal control, 32.0$\pm$13.9 $\mu$IU/mι; diabetic control, 12.4$\pm$1.9; G500, 17.5$\pm$3.4; M500, 11.1$\pm$3.2; GM250, 10.5$\pm$t3.7). Urine glucose levels were also remarkably reduced in all treatment groups (normal control, 0.0$\pm$0.0 g/day; diabetic control, 11.4$\pm$2.5; G500, 4.9$\pm$0.2; M500, 5.7$\pm$1.6 ; GM250, 8.2$\pm$0.2). At the second and third week of the treatment, food and water intakes were determined. At the third week, food and water intakes were significantly decreased in all treatment groups. Taken together, we may conclude that GRA and MF alone may prevent or delay the development of hyperglycemia, however, synergistic hypoglycemic activity was not be seen in group treated with mixed formula of GRA and MF when compared to GRA or MF alone.

  • The objective of the present study was to evaluate the effect of a mixed extract of three herbs, Panax Notoginseng, Rehmanniae Radix and Acanthopanacis cortex (AIF), for the treatment of horses with experimentally induced osteoarthritis. Twelve healthy male horses were included in this study. Horses were assigned to one of two groups: the AIF group (n=6) or the control group (n=6). Osteoarthritis was induced in all horses by intraarticular injection of sodium monoiodoacetate (0.12 mg/kg). Horses in the AIF group received 3 g of AIF with food daily, and those in the control group received food only. Treatment began on the day of intraarticular injection. Clinical and radiographic evaluations were performed every 2 weeks. At week 12, horses were euthanatized, and postmortem gross pathologic and histologic examinations of the middle carpal joint were performed. There were no significant differences in clinical values between the two groups. Radiographic evaluation revealed that the percentages of narrowness of joint space width in the control group were significantly higher than those in the AIF group (p<0.02). On gross pathologic examination, the mean total dimensions of articular cartilage erosions and fibrillations in the control group ($101.5{\pm}41.5mm^2$) were significantly wider than those in the AIF group ($29.3{\pm}39.7mm^2$; p<0.01). On histopathologic evaluation, significantly higher grades of staining intensity and lower empty lacunae (EL) ratios were found in the AIF group (p<0.03). The present study revealed that AIF had significant disease modifying effects in horses with experimentally induced osteoarthritis.

  • The objective of present study is to evaluate concentration-dependent in vitro anti-osteoarthritic (OA) effects of synergic mixed formula consisted of dried pomegranate juice concentrate powder, Eucommiae Cortex aqueous extract and Achyranthis Radix aqueous extract 5:4:1 (g/g) mixture on the primary cultured rat articular chondrocytes. First, any cytotoxic effect of mixture was observed using MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium Bromide) assay. Next, cyto-protective effect of test substances was evaluated by using the recombinant human interleukin $(rhIL)-1{\alpha}$ induced chondrocytes. In addition, anti-inflammatory effects were also observed on the lipopolysaccaride (LPS) treated chondrocytes through prostaglandin $E_2(PGE_2)$ productions and 5-lipoxygenase (LPO) activities, and inhibitory effects on matrix metalloproteinase (MMP)-2 and MMP-9 activities were observed on $rhIL-1{\alpha}$ treated chondrocytes with their extracellular matrix (ECM) related mRNA expressions. No obvious cytotoxic effects of mixture were demonstrated. Inflammatory damages of chondrocytes and related ECM degradations induced by treatment of LPS or $rhIL-1{\alpha}$ were significantly and concentration-dependently inhibited by pretreatment of mixture from a concentration level of 0.001 mg/ml to 1 mg/ml. In addition, mixture showed $IC_{50}$ for $rhIL-1{\alpha}-induced$ MMP-2 and MMP-9 activities as 44.01 and $162.47{\mu}g/ml$, and also showed $EC_{50}$ for $rhIL-1{\alpha}-induced$ inhibition of collagen type II, SOX9 and aggrecan mRNA expression as 8.61, 10.79 and $4.47{\mu}g/ml$, respectively. It is observed that mixture showed concentration-dependent anti-inflammatory and cytoprotective ECM preserved effects on the primary cultured rat articular chondrocytes without cytotoxicity.
