In order to investigate the Immunomodulatory effects of ginseng, we have studied the effects of ginseng saponin on the proliferation and cytosine gene expression of human pheripheral blood mononuclear cell (PBMC). In the PBMC proliferation assay, total saponin exhibited proliferation inhibition on the PBMC or phytohemagglutinin(PHA)-stimulated PBMC in a dose-dependent fashion. Immunomodulatory effects of ginseng were further investigated using the cytokine gene expression as the indicators. In the reverse transcription-polymerase chain reaction (RT-PCR) test, interleukin (IL)-1, IL-2, IL-3, IL-4, IL-6, IL-13, granulocyte macrophage-colony stimulating factor, tumor necrosis factor (TNF), migration inhibitory factor and transforming growth factor genes were expressed in the PHA-stimulated PBMC 48 hrs after cell culture. Among expressed cytokines, total saponin could increase the expression of IL-1 and TNF of PBMC without stimulation of PHA. All of ginsenosides, $Rb_1$, $Rb_2$, $Rg_1$, Rc, Re, incresed TNF gene expression. Especially, Rb2 (20 g/ml) showed most prominent effect on TNF gene expression and it also slightly increased IL-1 gene expression of PBMC.

This study was to evaluate the effect of Samjayangchin-tang (STYCT) on mouse Th1 and Th2 cells' differentiation and ovalbumin (OVA)-induced allergic inflammation. The proliferation of mouse CD4 T cells and the secretion of Th1/Th2 cytokines under the influence of STYCT extract were measured as well as the amount of ${\beta}-hexosaminidase$ in RBL-2H3 cells and the levels of $TNF-{\alpha}$ and IL-6 secretion in Raw264.7 cells. BALB/c mice were orally administered with STYCT extract and simultaneously inoculated with OVA to induce allergic reaction and measure the level of total IgE, OVA-specific IgE and the production of IFN- g, IL-4, IL-5 by the spleen cells. When mouse CD4 T cell were stimulated with anti-CO3 and anti-CD28 for 48 hours in various concentrations of STYCT extract, it decreased proliferation of CD4 cells. CD4 T cells under Th1/Th2 polarizing conditions for 3 days with STYCT resulted in mild decrease of IFN- g in Th1 cells and significant decrease of IL-4 in Th2 cells. STYCT extract had a dose-dependent inhibitory effect on antigen-induced release of ${\beta}-hexosaminidase$ in RBL-2H3 cells. Treatment of STYCT extract on LPS stimulated Raw 264.7 cells showed dose-dependent decrease in IL-6 production. Oral administration of STYCT extract on OVA-induced allergic mice showed an inhibitory effect on the levels of total serum IgE and OVA-specific IgE by 53% and 44%, respectively. Culture of spleen cells with OVA resulted in significant increase of IFN- g by 54% and significant decrease of IL-4 and IL-5 by 42%, and 29%, respectively. The results show that STYCT does not strongly induce mouse T cells to transform into Th1 or Th2 but it has an anti-allergic effect in vitro, and that it also corrects the unbalance between the reactions of Th cells in allergic diseases.

Pumpkin has long been used as traditional health materials in oriental medicine, pharmacy, medicine, and food industries in many countries. In this study, the water extract and two active components from tendril of young C. moschata Duch. were investigated on inflammation inhibitory activity. The water extract of young C. moschata Duch. showed high cell viability over 95% and it decreased the production of interlukin 6 (IL-6) and tumor necrosis factor (TNF-${\alpha}$) in the capacity of mouse bone marrow-derived macrophages (BMDM) upon lipopolysaccharide (LPS) stimulation. Also, isolated fraction (B4) suppressed the secretion of IL-6 and TNF-${\alpha}$. Among the domestically cultivated pumpkins, B4 fraction contained in the tendril part of them and it comprised of the order of tendril from Cucurbita pepo var. cylindrica, old of C. moschata Duch., and young of C. moschata Duch. These results suggest that water extracts of C. moschata Duch. and purified active compound, rutin, show anti-inflammation activity by suppression of the secretion of IL-6 and TNF-${\alpha}$. It can be applicable as pharmaceutical materials.

Cheonggeumganghwa-tang(CGT) has been used for the purpose of prevention and treatment of bronchial asthma and allergic asthma in Korea. To investigate the biological effect of CGT, the author examined cytotoxicity and inflammatory cytokines secretion with human mast cell line, HMC-1. HMC-1 was stimulated with phorbol 12-myristate 13-acetate (PMA) and calcium ionophore A23187. CGT by itself had no effect on viability of HMC-1. The effects of CGT on the secretion of tumor necrosis factor-alpha (TNF-α) and interleukin (IL)-6 from HMC-1 were evaluated with enzyme-linked immunosorbent assay (ELISA). CGT (1 ㎎/㎖) inhibited PMA plus A23187 -induced TNF-α and IL-6 secretion, by 93.86 ± 2.05%, 68.69 ± 2.86%, respectively. CGT also inhibited the NF-κB (p50) expression. Taken together, these results suggest that CGT inhibit the production of inflammatory cytokines in HMC-1 cells through blockade of NF-κB activation.

Objectives : Patrinia scabiosaefolia (PS) has long been as a remedy for treating infectious diseases in Korea. In the present experiments, the author examined the effects of PS on the cholecystokinin-octapeptide (CCK)-induced pancreatitis (AP) in rats. Methods : Male Wister rats weighing 200 to 250 g were divided into two group. Normal untreated group, in treatment with PS group; PS was administered orally, followed by $75{\mu}g/kg$ CCK subcutaneously three times, after 1, 3 and 5 h. This whole procedure was repeated for 5 days. In treatment with saline group, the protocol was the same as in treatment group with PS. The author determined the pancreatic weight/body weight ratio, the levels of pancreatic heat shock proteins(HSP)60, HSP72 and the secretion of pro-inflammatory cytokines. Results and Conclusion : PS was significantly decreased the pancreatic weight/body weight ratio in CCK-induced AP. PS increased HSP60 and HSP72 compared with CCK-induced AP. Additionally, the secretion of tumor necrosis factor(TNF)-${\alpha}$, interleukin(IL)-$1{\beta}$ and IL-6 the levels of amylase and lipase were lower than that of saline. These results suggest that PS may has a inhibitory effect against CCK-induced AP.

Prostate cancer is the most frequently diagnosed cancer. Although prostate tumors respond to androgen ablation therapy at an early stage, they often acquire the potential of androgen-independent growth. Elevated transcriptional activity of androgen receptor (AR) and/or signal transducer and activator of transcription-3 (STAT3) contributes to the proliferation of prostate cancer cells. In the present study, we examined the effect of resveratrol, a phytoalexin present in grapes, on the reporter gene activity of AR and STAT3 in human prostate cancer (LNCaP-FGC) cells stimulated with interleukin-6 (IL-6) and/or dihydrotestosterone (DHT). Our study revealed that resveratrol suppressed the growth of LNCaP-FGC cells in a time- and concentration-dependent manner. Whereas the AR transcriptional activity was induced by treatment with either IL-6 or DHT, the STAT3 transcriptional activity was induced only by treatment with IL-6 but not with DHT. Resveratrol significantly attenuated IL-6-induced STAT3 transcriptional activity, and DHT- or IL-6-induced AR transcriptional activity. Treatment of cells with DHT plus IL-6 significantly increased the AR transcriptional activity as compared to DHT or IL-6 treatment alone and resveratrol markedly diminished DHT plus IL-6-induced AR transcriptional activity. Furthermore, the production of prostate-specific antigen (PSA) was decreased by resveratrol in the DHT-, IL-6- or DHT plus IL-6-treated LNCaP-FGC cells. Taken together, the inhibitory effects of resveratrol on IL-6- and/or DHT-induced AR transcriptional activity in LNCaP prostate cancer cells are partly mediated through the suppression of STAT3 reporter gene activity, suggesting that resveratrol may be a promising therapeutic choice for the treatment of prostate cancer.

Thuja orientalis extract (TOS) has been used on the hemostatic roborant, sedatives and stressless in oriental countries. We investigate the inhibitory effects on the productions of pro-inflammatory cytokines such as interleukin-1beta (IL-1β), IL-6, tumour necrosis factor alpha (TNF-α), and nitric oxide (NO) and the hair promotiont of TOS in the macrophage celline RAW264.7 or hair loss-induced DBA1J mice. T08 (50-500 ㎍/㎖) per se had no cytotoxic effect non-stimulated cells, but this extracts concentration-dependently reduced the release of NO, (IL-1β), IL-6, and TNF-α in the stimulate RAW264.7 cells with lipopolysaccharide (LPS). Moreover, when applied TOS (500 ㎍/㎖) to DBA 1J/mice, hair growth was promoted remarkably. These data suggest that T08 promotes hair growth on hair loss induced model mice and these properties may contribute to the anti- hair loss activity of the Thuja orientalis.
