Objectives : Regulatory T cells can reduce inflammation and allergic reactions through their inhibitory functions. Gardeniae Fructus(GF) is a Heat-clearing herb used in traditional Korean medicine, and a wide range of studies on its antiinflammatory effects are being carried out. The authors investigated the effect that Gardeniae Fructus has on regulatory T cells. Methods : The authors screened 14 herbs for their effects on regulatory T cells. 100mg of each herb were separately dissolved in 1ml of sterile saline and the supernatant was harvested after 10 minutes of centrifuge at 15,000 rpm. The supernatant was filtered through a 0.2 ${\mu}m$ syringe filter, and the resulting stock was refrigerated at $4^{\circ}C$. The stock was diluted before testing and used at a final concentration of $0.01{\mu}g/ml$. CD4+CD25+ T cells from healthy BALB/c spleens were used as natural regulatory T cells (nTreg), and CD4+CD25- T cells were used as reactive T cells. CD4+CD25+ and CD4+CD25- T cells were activated with anti-CD3e ($10{\mu}g/m{\ell}$)/anti-CD28 ($1{\mu}g/m{\ell}$) and cultured. IL-10 from supernatant of the culture medium was measured by IL-10 cytokine ELISA. The percentages, cell numbers, phenotype and function of CD4+CD25+ Treg cells were determined by flow cytometry. Results : Gardeniae Fructus was shown to be the most potent herb among the 14 herbs tested for suppressing CD4+CD25- reactive T cell proliferation by stimulating CD4+CD25+ natural regulatory T cells. Gardeniae Fructus induces IL-10 secretion increase by stimulating CD4+CD25+ natural regulatory T cells, and indirectly suppresses CD4+CD25- reactive T cell proliferation through increasing CD25 (IL-2 receptor $\alpha$) expression and thus promoting bonding with IL-2. Gardeniae Fructus did not directly affect CD4+CD25- reactive T cell proliferation. Conclusions : Gardeniae Fructus suppressed reactive T cell proliferation through inducing increases in IL-10 secretion and CD25 (IL-2 receptor $\alpha$) expression.

Objectives : The objective of the paper was to study cutting method of Gardeniae frutus, that tends to show symptom of separations in a packing, in accordance with the comparison experiment of quantification and antioxidant effect proceed with the intact Gardeniae fructus(Gf), seed of Gardeniae fructus (Gs) and the pericarp of Gardeniae fructus (Gp) separately. Methods : The Gf, Gs, and Gp were extracted using 80% MeOH, followed by quantizing geniposide contained in each group. A MTT assay was conducted and ROS generation and NO production were measured for comparing its antioxidant effect. Results : As a result of quantizing geniposide contained in the Gf, Gp, and Gs, respectively, the geniposide content was shown to be the highest in the Gs. MTT assay showed that no cytotoxicity was observed in the groups treated with Gf, Gp, and Gs, respectively, at a dose of 500 ${\mu}g/ml$. The ROS generation was shown to have more significantly decreased in the group pretreated with Gf 500 ${\mu}g/ml$ than in the group treated with LPS. The NO level was shown to have more significantly decreased in the group pretreated with Gp 500 ${\mu}g/ml$ than in the group treated with LPS. Conclusion : As the geniposide content and antioxidant effect of Gf varies according to its each part, it is recommended that Gf should be distributed as an intact form other than segregation in packing.

Objectives: Chijasitang (CJST) has been prescribed for patients with anxiety disorder, and is believed to treat insomnia. The present study was carried out to investigate whether Fructus Gardeniae, Fermented Semen Sojae Preparatum and CJST have beneficial effects on treating anti-stress. Methods: The mice were divided into the following groups: normal, control, positive control, and experimental. Then, the experimental groups were further divided into the Fructus Gardeniae group (FG), the Fermented Semen Sojae Preparatum group (FS), the Chijasitang water extract group (CJSTW), and the Chijasitang 30% ethanol extract group (CJSTE). In the positive control group, a single dose of imipramine ($500{\mu}g/g$) was applied to the mice. In the experimental groups, each single dose of FG, FS, CJSTW and CJSTE ($50{\mu}g/g$) was applied to the mice. After one hour, the mice in all groups except the normal group were exposed to immobilization stress. Their body weights, phagocytosis, nitric oxide in macrophage, corticosterone, and adrenocorticotropic hormone (ACTH) were observed. Results: Fructus Gardeniae, Fermented Semen Sojae Preparatum and Chijasitang prevented weight loss and suppressed the decrease of phagocytosis in the mice after their exposure to immobilization-stress. Although they did not influence the amount of NO, they suppressed the increment of ACTH and corticosterone in the immobilization-stressed mice. Conclusions: According to the results of this study, they suggest that Fructus Gardeniae, Fermented Semen Sojae Preparatum and Chi-Ja-Si-Tang all have some anti-stress effects.

Objectives: The object of this study was to observe the in vitro anti-bacterial and anti-inflammatory effects of three single aqueous herbal extracts(Trichosanthes Semen, Gardeniae Fructus, and Angelicae Dahuricae Radix), traditionally used for treating various gynecological diseases including mastitis in Korea, against Staphylococcus aureus and lipopolysaccharide(LPS)-activated Raw 264.7 cells. Methods: Anti-bacterial activities of three single aqueous herbal extracts against S. aureus were detected using standard agar microdilution methods. In addition, the effects on the cell viability, $PGE_2$, NO, TNF-${\alpha}$, IL-$1{\beta}$ and IL-6 productions of LPS activated Raw 264.7 cells. The anti-bacterial and anti-inflammatory effects were compared with lincomycin and piroxicam, respectively in the present study. Results: MIC of three single aqueous herbal extracts against S. aureus were detected as over 25, $4.063{\pm}2.096$ and $1.641{\pm}0.972$ mg/ml, respectively. MIC of lincomycin was detected as $0.469{\pm}0.297{\mu}g/ml$ at same conditions. In addition, $ED_{50}$ against LPS-induced cell viabilities and cytokine releases of three single aqueous herbal extracts were as follows - cell viability: 7.635, 13.761, 6.986 mg/ml, NO production : 4.808, 22.015, 2.949 mg/ml, $PGE_2$ production : 3.040, 4.312, 0.821 mg/ml, TNF-${\alpha}$ production : 9.563, 54.931, 1.240 mg/ml, IL-$1{\beta}$ production : 1.362, 1.801, 0.534 mg/ml, IL-6 production : 0.371, 0.797, 0.202 mg/ml, respectively. $ED_{50}$ of piroxicam against LPS-induced cell viabilities, NO, $PGE_2$, TNF-${\alpha}$, IL-$1{\beta}$ and IL-6 were detected as 35.179, 6.552, 1.162, 7.273, 7.101 and 5.044 ${\mu}g/ml$, respectively at same conditions. Conclusions: The results of the study showed anti-bacterial effects against S. aureus in the order of Gardeniae Fructus and Angelicae Dahuricae Radix aqueous extracts, except for Trichosanthes Semen. They also showed anti-inflammatory effects against LPS-activated Raw 264.7 cells in the order of Angelicae Dahuricae Radix, Trichosanthes Semen, and Gardeniae Fructus aqueous extracts. These three herbs are expected to be great substitutes to reduce side-effect of lincomycin and piroxicam, if the amount of those three single aqueous herbal extracts is adjusted appropriately.
