The purpose of the present study was to investigate the effect of IFN-${\tau}$ on prostaglandin synthesis, cyclooxygenase-2 (COX-2) gene expression in vitro and concentration of progesterone (P4) in endometrial cells. Epithelial and stromal cells cultured in vitro were isolated from bovine endometrium and stimulated with increasing doses of IFN-${\tau}$ (0, 0.02, 0.2 and 2 ug/ml). Human chorionic gonadotropin (hCG, 1.5 IU/ml) was used as a positive control. Prostaglandin $E_2$ and $F_{2{\alpha}}$ levels in the culture media were analyzed by enzyme immunoassays and total RNA was extracted from the cells for RT-PCR. P4 concentrations of blood samples were assayed by chemiluminescent immuno assays system. In epithelial cells, COX-2 gene expression was increased in the presence of IFN-${\tau}$ (p<0.05), but it was not significantly different in all groups of stromal cells except for 2 ug/ml IFN-${\tau}$ group (p<0.05). Although IFN-${\tau}$ did not affect $PGE_2$ and $PGF_{2{\alpha}}$ production in epithelial cells, it decreased $PGE_2$ and $PGF_{2{\alpha}}$ production significantly in stromal cells (p<0.05). In vivo experiment, blood concentration of P4 was significantly increased after addition of IFN-${\tau}$ (1 ug/ml). The results indicate that PG production was mediated by COX-2 expression in stromal cells but it was not affected in epithelial cells and this suggest that treatment of IFN-${\tau}$ could improve the implantation environment of uterine by maintenance of high P4 concentration.

This study was conducted to develop functional sources of herbal cosmetics for treatment of skin aging and inflammatory disorders using volatile flavor extracts of four different herbal medicinal prescriptions including Cnidium officinale Makino (COM), Angelica gigas Nakai (AGN), Mentha arvense L. (MAL), Artemisiae argyi Folium (AAF), Paeonia lactiflora Pall (PLP), Rehmanniae Radix Preparata (RRP), Scutellaria baicalensis Georgi (SBG), Panax ginseng C.A. Meyer (PGM), Glycyrrhiza uralensis Fisch (GUF). The volatile flavor extracts of four different herbal medicinal prescriptions (HH-1: COM, AGN, PLP, RRP, HH-2: COM, AGN, PLP, RRP, SBG, PGM, GUF, HH-3: COM, AGN, MAL, AAF, HH-4: COM, AGN, MAL, AAF, SBG, PGM, GUF) were extracted using SDE and their antioxidant and anti-inflammatory effects were measured by using DPPH radical and SLO, respectively. As a result, HH-2 showed moderate DPPH radical scavenging activity (68.24 %) and the strongest SLO inhibitory activity (83.96 %) at 100 ${\mu}g$/mL. Moreover, HH-2 of four different prescriptions significantly inhibited NO production on LPS-stimulated RAW 264.7 cells in a dose-dependent manner without considerable cell cytotoxicity at range of 2.0 ~ 50 ${\mu}g$/mL. Additionally, HH-2 also effectively suppressed the production of $PGE_2$ and IL-6, which are responsible for promoting the inflammatory process. Major volatile components of HH-2 were identified as eugenol, paeonol, butyl phthalide, ${\beta}$-eudesmol and butylidene dihydrophthalide by GC-MS analysis. Thus, these results suggest that HH-2 may be useful as a potential source of anti-inflammatory agents in herbal medicinal cosmetics.

Objectives This study was performed to investigate the effects of Bujasasim-tang ethanol extract (BST) on oxidative stress, inflammation and osteoarthritic rat model. Methods To ensure safety of BST, heavy metal levels were measured and cytotoxicity test was done. In vitro, To evaluate antioxidative effects of BST, total phenolic contents, 1,1-diphenyl-2-picryl-hydrazyl (DPPH), 2,2'-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) scavenging activity, reactive oxygen species (ROS) levels were measured. Also, to evaluate anti-inflammatory effects of BST treated group, total nitric oxide (NO) and pro-inflammatory cytokines (IL-$1{\beta}$, IL-6, TNF-${\alpha}$) levels were measured in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. In vivo, We injected MIA $50{\mu}l$ (60 mg/ml) into knee joints of rats to induce osteoarthritis. Rats were divided into total 3 groups (normal, control, BST treated group, each n=7). Normal group was not treated at all without inducing osteoarthritis and taken normal diet. Control group was induced osteoarthritis by MIA and taken with 2 ml of distilled water once a day for 4 weeks. BST treated group was induced osteoarthritis by MIA and taken BST 2 ml (200 mg/kg/mouse) once a day for 4 weeks. We evaluated dynamic weight bearing with the Incapacitance Test Meter. At the end of experiment, the rats were sacrificed to observe the functions of liver and kidney, changes of WBC, neutrophil, lymphocyte, monocyte levels in blood, to evaluate the levels of pro-inflammatory cytokines, tissue inhibitor of metallopreteinases-1 (TIMP-1), matrix metalloproteinase-9 (MMP-9), prostaglandin $E_2$ ($PGE_2$), leukotriene $B_4$ ($LTB_4$) within serum. We observed change of articular structures by Hematoxylin & Eosin (H&E), safranin-O staining method and measured amount of cartilage by micro CT-arthrography. Statistical analysis was done by unpaired student's t-test with significance level at p<0.05 in SPSS 11.0 for windows. Results 1. Safety of the BST was identified. 2. AST, ALT, BUN, creatinine levels of BST treated group were within normal limit. In vitro, 1. DPPH and ABTS free radical scavenging activities of BST showed dose-dependent increase. 2. ROS production were significantly decreased. 3. Total nitric oxide (NO) and IL-$1{\beta}$ production were decreased. 4. IL-6 and TNF-${\alpha}$ production were significantly decreased. In vivo, 1. Weight bearing ability was significantly increased. 2. WBC, neutrophil, lymphocyte, monocyte levels in blood were decreased. 3. IL-$1{\beta}$ and TNF-${\alpha}$ levels in serum were significantly decreased. and the IL-6 level was decreased. 4. TIMP-1, MMP-9, $LTB_4$, $PGE_2$ levels in serum were significantly decreased. 5. Cartilage volume of BST treated group was significantly increased. Also changes of cartilage, synovial membrane, fibrous tissue were suppressed. Conclusions The results obtained in this study Bujasasim-tang have effects of antioxidative, anti-inflammatory, relieve pain and protection of cartilage. Therefore we expect that Bujasasim-tang is effective treatment for osteoarthritis.

Silsosangami(SSG) is a formula of oriental medicines as an effective biological response modifier for augmenting host homeostasis of body circulation. Also SSG has been known to have an anti-diabetic activity and anti-platelet aggregation activity. The present study was undertaken to examine the effects of a new SSG on murine macrophage and human neutrophil functions as well as on several enzymes relevant to the inflammatory process. The results of the present study indicate that SSG exerts anti-inflammatory effects related to the inhibition of neutrophil functions and of PGE2 production, which could be due to a decreased expression of and COX-2.

Present study was aimed to examine whether indomethacin affected the production of NO in the rat paw exudate by carrageenin. Paw edema and nitrite/nitrate levels in the paw exudate were maximal after 4 h and remained elevated up to 10 h, whereas indomethacin (10 mg/kg, po) significantly inhibited the carrageenin-induced paw edema and levels of nitrate in the paw exudate. However, paw edema and nitrite/nitrite levels were increased thereafter for 10 h. Indomethacin also enhanced the expression of iNOS mRNA and protein 4 h after carrageenin infection. Indomethacin inhibited the level of $PGE_2$ in the paw exudate in a time-dependent manner. These results suggest the possibility that indomethacin may potentiate expression of iNOS and subsequently increase nitrite/nitrate level in the late phase of carrageenin-induced rat paw inflammation possibly by suppressing cycloxygenase activity.

This study was performed to evaluate the effect of Carthami tinctorius(HH) on osteoblast function and gene expression. The osteoblasts separated from the rat calvariae were cultivated to evaluate the cell function, and MG-63 cell was also cultivated for the test of mRNA synthesis. In this experiments, cell proliferation of rat calvarial cells was increased by HH. PKC activity, intracellular free calcium level and collgen synthesis from calvarial cells were increased by HH, but not PKA activity. And the mRNA of $PLA_2$, COX-2, and $PGE_2$ synthase from MG-63 were decreased by HH, but the mRNA of prostacyclin synthase was increased. It is concluded that HH might increase the proliferation of calvarial cell resulted from augumentation of osteoblast activity and its mRNA synthesis.

Angelica keiskei has exhibited numerous pharmacological effects including antitumor, antimetastatic, and antidiabetic effects. However, the anti-inflammatory effects and mechanisms employed by xanthoangelol E isolated from Angelica keiskei are incompletely understood. In this study, we attempted to determine the effects of Xanthoangelol E on the lipopolysaccharide (LPS)-stimulated mouse peritoneal macrophage. The findings of this study demonstrated that xanthoangelol E inhibited the production of tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-6, and prostaglandin $E_2$ ($PGE_2$). Xanthoangelol E inhibited the enhanced levels of cyclooxygenase (COX)-2 and inducible nitric oxide synthase (iNOS) caused by LPS. Additionally, we showed that the anti-inflammatory effect of xanthoangelol E is through the regulation of the activation of nuclear factor (NF)-${\kappa}B$ and caspase-1. These results provide novel insights into the pharmacological actions of xanthoangelol E as a potential candidate for the development of new drugs to treat inflammatory diseases.

Poria cocos is a natural substance known to have anticancer, antioxidant and anti-inflammatory effects. The aim of this study is to investigate the analgesic effects of Poria cocos extract (PCE). We evaluated the analgesic effects of PCE using adjuvant induced arthritis rat model. Male SD rats were administered intra-orally with PCE according to prescribed dosage, during 6 days. After 6 days later, serum TNF-α, IL-1β, and IL-6 levels were measured by ELISA. In our experiment, administration of PCE decreased TNF-α, IL-1β, IL-6 and PGE2 level in serum. Furthermore, it was confirmed that allodynia was relieved in evaluation of pain behavior. It was confirmed that administration of PCE reduces nociceptive pain by reducing nociceptive stimuli by acting as an anti-inflammatory drug.
