Objectives The suppressive effect of CSBHT has been mysterious. Thus, the present study is designed to investigate the suppressive effect and its mechanism. Methods To investigate the anti-allergy effect from ChungShimBoHyeolTang(CSBHT), RBL-2H3 cell was used and examined by Real-Time PCR, and IL-4 and IL-13 from RBL-2H3 was examined by ELIS. In addition, GATA-1, GATA-2, NFAT-1, NFAT-2, c-Fos, c-Jun, NF-${\kappa}B$ p65 transcription factors of RBL-2H3 mast cell were examined by Western Blotting. Also, OVA/alum-sensitized mice were orally administrated CSBHT and serum OVA-specific IgE production, IL-4, and IL-13 production in splenocytes supernatant were examined. Results As a result of treating with CSBHT extract, RBL-2H3 mast cells significantly suppressed the IL-4 and IL-13 mRNA expression and IL-4 and IL-13 production. Western blot analysis of transcription factors involving IL-4 and IL-13 expression also revealed a prominent decreases of mast cell's specific transcription factors including GATA-1, GATA-2, NFAT-1, NFAT-2, c-Fos, and NF-${\kappa}B$ p65. Also, examining the mice, administration of CSBHT suppressed the amount of OVA-specific IgE in OVA/alum-sensitized mice and IL-4 and IL-13 production in splenocytes supernatant. Conclusions The study suggested that the anti-allergic activities of CSBHT suppresses IL-4 and IL-13 production from the Th2 cytokines by suppressing transcription factors as GATA-1, GATA-2, NFAT-1, NFAT-2, c-Fos and NF-${\kappa}B$ p65 in mast cells.

In the intestinal mucosa, mast cells are thought to be responsible for the expulsion of parasites. We investigated the relationship of worm expulsion and mast cells in C3H/HeN and BALB/c mice infected with Echinostoma hortense. In addition, we examined whether the worm recovery rate was associated with the strain of mice, and whether a toluidine stain and immunohistochemistry using the c-kit antibody was effective in the detection of mast cells. In order to investigate the mucosal immune response of C3H/HeN and BALB/c mice, each mouse was infected orally with 30 E. hortense metacercariae. Then, the number of mucosal mast cells and worm recovery rates was observed in experimentally infected mouse strains between 1 week and 8 weeks post infection (PI). Mucosal mast cells were increased in 3 weeks P.I. in C3H/HeN and BALB/c mice. On the other hand, only mucosal goblet cells and worm recovery rates correlated in C3H/HeN mice (P=0.0482). Worm recoveries in C3H/HeN mice were 65.7$\pm$5.6, 53.3$\pm$5.4 and 6.7$\pm$0.6 in week 1, 2, and 3 P.I. and strongly decreased in week 3 P.I. Worm recoveries in BALB/c mice were 23.0$\pm$2.5, 10.0$\pm$1.0, and 6.7$\pm$0.6% in week 1, 2, and 3 P.I. and gradually decreased from week 1 P.I. to week 3 P.I. Worm recoveries in C3H/HeN mice were significantly higher than in BALB/c mice (P<0.00l). The number of mast cells in C3H/HeN and BALB/c mice using the anti-c-kit antibody reached to a peak in week 3 P.I. and recovered as normal level in week 5 P.I. and 6 P.I. The number in E. hortense-infected C3H/HeN mice (P=0.0015) was higher than in E. hortense-infected BALB/c mice (P=0.01) compared with the control group. There were significant differences in the number of mast cells among regions of the intestine in in C3H/HeN mice (P<0.05) but not in BALB/c mice (P>0.05). Immunohistochemistry using the anti-c-kit antibody was significant method as an examination of the number of mast cells (P=0.0002). In conclusion, the present study demonstrated that mast cells play an important role in worm recovery, and immunohistochemistry using the anti-c-kit antibody was superior to toluidine stain as an examination of mast cells.

동백잎의 열수 추출물이 신생혈관 생성억제 효과가 강하게 나타남으로써 이들 추출물에 대한 독성 시험을 HUVECs를 사용하여 검토한 바는 200 ug/mL에서도 독성이 없는 것으로 나타났으며, 1.5, 3.0, 15 및 30 ug/mL으로 농도가 증가함에 따라 각각 30.7%, 38.5%, 53.8% 그리고 70.0%의 신생혈관 생성억제율을 보였다. 세포부착 저해효과는 C. japonica leaf (CJL)의 농도가 50, 100, $200{\mu}g{/well}$으로 증가할 때 E-selectin이 46.7%, 66.7% 그리고 86.76%, VCAM-1이 23.0%, 61.5% 그리고 84.6%, ICAM-1이 11.0%, 55.5% 그리고 88.8%로 나타났다. C. japonica leaf (CJL)의 성분 증가에 따라 발현이 감소되는 것을 보아 농도가 증가함에 따라 cell adhesion의 저해 효과가 높아짐을 알 수 있었다. 신호전달의 기전규명은 western blot으로 행하였으며 CJL의 농도가 증가함에 따라 밴드의 발현이 약해지는 것을 관찰할 수 있다. 따라서 신호전달 분자인 VEGFR-2, $\beta$-catenin, Pl3-K는 CJL에 의해 신호전달이 차단되는 것을 볼 수 있고, 이는 NF-${\kappa}$B를 억제함으로서 신생혈관 생성을 저해하는 것으로 확인되었다. 따라서 동백잎은 신생혈관 생성에 의존하고 있는 것으로 알려진 암 등의 치료와 암전이의 억제, 류마치스성 관절염, 그리고 항비만제제로서 개발될 수 있음을 시사한다.

The effect of aqueous extract of Lycopus lucidus Turcz. (Labiatae)(LLAE) on mast cell-mediated immediate-type allergic reactions was investigated. LLAE (0.01 to 1 mg/g) dose-dependently inhibited systemic anaphylaxis induced by compound 48/80. LLAE (0.001 to 1 mg/g) also dose-dependently inhibited local anaphylaxis activated by anti-dinitrophenyl (DNP) IgE. When LLAE was pretreated at the same concentration with systemic anaphylaxis, serum histamine levels were reduced in a dose-dependent manner. LLAE (0.001 to 1 mg/mι) dose-dependently inhibited histamine release from rat peritoneal mast cells (RPMC) activated by compound 48/80. The level of cAMP in human mast cell line (HMC-1) cells, when LLAE (1 mg/mι) was added, significantly was increased, compared with that of normal control. These results provide evidences that LLAE may be beneficial in the treatment of allergic diseases.

Objectives : The objective of present study is to evaluate anti-inflammatory and anti-allergic effects of Perilla(Perilla frutescens; Labiatae, PF), the roots of Peucedanum praeruptorum(PP) and the root of Scutellaria baicalensis(SB) in vitro and anti-asthmatic effects of mixture of PF, PP and SB(PS) on ovalbumin (OVA)-induced asthma in BALB/c mice. Methods : Anti-inflammatory and anti-allergic effects were observed on the lipopolysaccharide(LPS) treated RAW 264.7 cells through Nitric Oxide(NO) production and RBL-2H3 cells through ${\beta}$-hexosaminidase. Anti-asthmatic effects were observed on the number of inflammatory cells in bronchoalveolar lavage fluid(BALF) and the level of IgE in serum on OVA-induced BALB/c mice. Results : The treatment of PF, PP and SB(12.5, 25, 50, $100{\mu}g/m{\ell}$) resulted in a significant inhibition of NO production in RAW 264.7 cells and mast cell degranulation in RBL-2H3 cells. Oral administration of PS(400mg/kg/day) resulted in a significant reduction in the numbers of eosinophils in BALF and level of IgE in serum. Conclusion : The oral administration of PS is effective in ameliorating the eosinophilic infiltration in vivo and thus can be a good therapeutic candidate for allergic asthma.

Objectives: This study seeks to investigate the effects of Gamidohongsamul-tang (GDT) on the Gene expression levels of eNOS, KLF2, ICAM-1 and VCAM-1 in HUVEC cells. Methods: HUVEC cells were treated at a concentration of 1, 10, 100 (${\mu}g/ml$) of Gamidohongsamul-tang (GDT). To measure the NOS, KLF2, ICAM-1 and VCAM-1 gene expression in HUVEC cells, the synthesized cDNA was subjected to polymerase chain reaction (PCR) and electrophoresis was performed to verify gene expression level. Results: 1. GDT significantly increased eNOS and KLF2 gene expression. 2. GDT significantly reduced ICAM-1 and VCAM-1 gene expression. Conclusions: These experiments suggest that Gamidohongsamul-tang (GDT) regulates gene expression related with anti-dyslipidemic effects in HUVEC cells. In order to clinically apply this to diseases related to dyslipidemia, such as cardiovascular disease, additional in vivo experiments are needed to verify the anti-dyslipidemic effects of GDT.

Cotoneaster horizontalis Decne 에탄올 추출물(CHEE)의 항산화능과 항염증 생리활성을 분석하였다. CHEE의 항산화능을 DPPH radical scavenging activity로 분석한 결과 radical 소거능의 정도가 양성 대조군으로 사용한 ascorbic acid와 유사한 정도의 높은 활성을 보여 매우 강한 항산화능을 보유함을 확인하였다. 또한 RAW 264.7 세포주를 이용하여 H₂O₂ 유도에 의해 생성된 ROS에 대한 소거능을 분석한 결과에서도 강한 소거능을 보였다. 뿐만 아니라 항산화효소 HO-1 및 그 전사 인자인 Nrf2의 단백질 발현이 CHEE의 처리에 의해 증가되었다. 한편 CHEE가 LPS에 의해 유도된 NO 생성에 미치는 영향을 분석한 결과 농도의존적인 NO 생성 저해능을 보였으며 이는 NO 생성 단백질인 iNOS의 발현 저해에서 기인함을 확인하였다. 이러한 결과를 통해 C. horizontalis의 항산화능과 항염증 활성을 세포 수준에서 처음으로 확인하였으며 향후 기능성 소재로서 유용하게 활용될 수 있을 것으로 판단된다.

Purpose: Cytolethal distending toxin (CDT) considered as a key factor of localized aggressive periodontitis, endocarditis, meningitis, and osteomyelitis is composed of five open reading frames (ORFs). Among of them, the individual role of CdtA and CdtC is not clear; several reports presents that CDT is an AB2 toxin and they enters the host cell via clathrin-coated pits or through the interaction with GM3 ganglioside. So, CdtA, CdtC, or both seem to be required for the delivery of the CdtB protein into the host cell. Moreover, recombinant CDT was suggested as good vaccine material and antibody against CDT can be used for neutralization or for a detection kit. Materials and Methods: We constructed the pET28a-cdtC plasmid from Aggregatibacter actinomycetemcomitans Y4 by genomic DNA PCR and expressed in BL21 (DE3) Escherichia coli system. We obtained the antibody against the recombinant CdtC in mice system. Using the anti-CdtC antibody, we test the native CdtC detection by ELISA and Western Blotting and confirm the expression time of native CdtC protein during the growth phase of A. actinomycetemcomitans. Results: In this study we reconstructed CdtC subunit of A. actinomycetemcomitans Y4 and generated the anti CdtC antibody against recombinant CdtC subunit expressed in E. coli system. Our anti CdtC antibody can be interacting with recombinant CdtC and native CDT in ELISA and Western system. Also, CDT holotoxin existed at 24h but not at 48h meaning that CDT holotoxin was assembled at specific time during the bacterial growth. Conclusion: In conclusion, we thought that our anti CdtC antibody could be used mucosal adjuvant or detection kit development, because it could interact with native CDT holotoxin.
