  • Chemokines are important for the recruitment of leukocytes to sites of infection, which is essential in host defense. The thymus and activation-regulated chemokine (TARC) is a CC chemokine which potentially plays a role via a paracrine mechanism in the development of allergic respiratory diseases. Objectives : The objective of this study is to investigate the effect of Youn-Gyo-Pae-Doc-San on the secretion of TARC of human bronchial epithelial cell Methods : Enzyme-linked immunosorbent assay (ELISA) was performed to detect the secretion of TARC. The cytotoxicity was measured by MTT assay. Results : Youn-Gyo-Pae-Doc-San significantly inhibited the secretion of TARC with a dose -dependant manner. The effective dosage did not have the cytotoxicity on human bronchial epithelial cell. Conclusions : Results of our study show that Youn-Gyo-Pae-Doc-San would play an important role in modulation of TARC in human bronchial epithelial cells.

  • 저온 플라즈마를 발생시키는 대기압 마이크로-플라즈마 젯(Micro-plasma jet)을 이용하여 플라즈마와 세포와의 상호작용에 대한 연구를 진행하였다. 세포의 대사과정에서 생성되는 활성산소 종(Reactive Oxygen Species, ROS)은 세포에 산화 스트레스를 유발시킨다. 이러한 스트레스는 세포 예정사(programmed cell death)의 원인이 된다. 플라즈마 형성 기체로 헬륨, 아르곤, 질소를 사용하여 각각의 기체에 따른 세포의 형태 변화 및 세포 내 활성 산소 종의 영향을 분석하였다. 실험에 사용된 세포는 인체의 폐암 세포[Human lung cancer cell, A549]이며 플라즈마 처리 후 Intracellular ROS assay를 통하여 플라즈마에서 발생되는 활성 산소 종(Reactive Oxygen Species, ROS)이 세포 내에 들어가 활성 산소 종을 증가시키는 것을 확인하였다. 이때, 플라즈마에서 발생되는 활성 산소 종(Reactive Oxygen Species, ROS)들은 광 방출 스펙트럼(Optical Emission Spectroscopy)로 분석하였고, 기체별로 비교하여 보았다. 또한, 이 때 발생되는 플라즈마의 전류-전압 특성에 따른 optical intensity를 비교하였다.

  • Five known compounds, cimigenol (1), 25-O-acetylcimigenol (2), cimigenol 3-O-${\beta}$-D-xylopyranoside (3), ferulic acid methyl ester (4), and visnagin (5), were isolated from Cimicifugae Rhizoma (Ranunculaceae). The chemical structures of these compounds were determined on the basis of spectroscopic analyses including 2D NMR. Compounds 1 - 5 were evaluated for their cytotoxic activity against the HL-60, MCF-7, and A549 cancer cell lines in in vitro. Among them, compounds 4 and 5 showed moderate inhibitory activity against HL-60 cancer cell lines with $IC_{50}$ values of 24.8 and 18.1 ${\mu}M$, respectively.

  • Two new sulfated saponins designated as certonardosides P$_{2}$ and I$_{3}$ (1 and 2) were isolated from the brine shrimp active fraction of the MeOH extract of the starfish Certonardoa semiregularis. The structures were determined on the basis of spectral analysis. Compounds 1 and 2 were tested for cytotoxicity against five human tumor cell lines (A549, SK-OV-3, SK-MEL-2, XF498, and HCT15), and compound 1 displayed significant cytotoxicity against the SK-MEL-2 skin cancer cell.

  • Bioassay-guided fractionation of the aerial parts of Pilea mongolica(Urticaceae) afforded two cytotoxic triterpenoids, epi-oleanolic acid (I) and oxo-oleanolic acid (II). The structures of the compounds were confirmed by spectral and synthetic evidences. Compound I and compound II exhibited cytotoxicity against cultured human tumor cell lines, A549 (non small cell lung adenocarcinoma), SK-OV-3 (ovarian), SK-MEL-2 (skin melanoma), XF498 (CNS) and HCT15 (colon) with $ED_{50}$ values of $3.2-8.1{\mu}g/ml$ and $0.7-6.8 {\mu}g/ml$, respectively.

  • The cytotoxicity-guided fractionation of the roots of Sophora flavescens (Leguminosae) extracts led to the isolation of fifteen active principles 1~15, responsible for the cytotoxicity against five kinds of cultured human tumor cell lines, i.e., A549(non small cell lung), SK-OV-3(ovary), SK-MEL-2(skin), XF498(central nerve system) and HCT-15(colon), evaluated by SRB method in vitro. Compounds 2~14 were classified as unusual flavonoid occurred exclusively in this species and the proliferation of each examined tumor cells were significantly inhibited during the continuous exposure to compounds 1~15 for 48 hours, respectively.

  • For probing the importance of planarity of imidazolidinone motif of 4-phenyl-1-(N-acylindoline-5-sulfonyl)imidazolidinones 1 for their cytotoxicity, 4-phenyl-1-(N-acylindoline-5-sulfonyl)[1,2,5]thiadiazolidine-1,1-dioxides 2 were prepared and their cytotoxicity were measured against human lung carcinoma (A549), human colon carcinoma (COLO205), human ovarian cancer (SK-OV-3), human leukemic cancer (K562), and murine colon adenocarcinoma (Colon26) cell lines in vitro. Although only carbonyl moiety of imidazolidinone ring was replaced with sulfonyl group, compounds 2 do not show any activity against all five cancer cell lines unlike 1. Therefore the planarity of imidazolidinone ring of 1 should be an important factor for their cytotoxic activity.

  • The antimutagenic and cancer cell growth inhibitory effects of woorimil contained herb and seaweed powders were examined. While woorimil itself showed only 40% antimutagenic effect on S. typhymurium TA98 against 4NQO(0.15 g/plate), water extracts of mountain herbs and seweeds including Comfrey, wormwood, Kale, Angelica utilis and pine leaves showed 80~90% antimutagenicity. On the other hand, these extracts along with woorimil showed 68 to 80% antimutagenic activities. Low antimutagenic activities of less than 50% were shown when these extracts were tested on TA98 against Trp P 1(0.5 g/plate), but high antimutagenic activities of 80~93.3% were shown on TA100. Water extracts of Capsella bursa pastoris and Allium grayi exhibited 60~80% of the activites in cytotoxicity tests of woorimil water extracts(0.5mg/ml) on human lung carcinoma cell. A549 showed 10% cell growth inhibitory effect. When mixed with Comfrey and Angelica utilis extracts, it showed 23~25% inhibition and other extracts showed only 12~23% inhibition. Cytotoxicity test of woorimil extracts on human liver cancer cell Hep3B revealed 20% inhibition. The additions of pine needle extracts, Angelica utilis and Comfrey showed 33%, 29% and 25% inhibition, respectively. But other extracts showed only 20% inhibition.

  • Anti-angiogenesis is one of therapies which have been high-lightened on the research of cancer treatment. Anti-angiogenesis means that new blood vessels are created from a existing capillary tube and it is a important process on metastasis and permeation when cancer is created or formed. Since angiogenesis have been under research, a complete recovery oriented treatment against cancer have been suggested blocking metastasis, delaying the growth of cancer cell, and blocking the supply of oxygen and nutritive substance through the web of blood vessels. Until now, there are several anti-angiogenesis, which have been known to the public, such as thalidomide, angiostatin, endostatin, 2-methoxyestradiol, TNP-470, and marimastat, etc. Additionally, 17 clinical testing projects about anti-angiogenesis are on the process in NCI(National Cancer Institute). Especially, TNP-470 showed effectiveness against cancer on clinical testing after finishing animal testing. Based on existing researches showing that Yinsamyangwui-tang is effective to strengthening body resistance and Whallakhyolenyng-dan effects cells on the inside of blood vessel because Whallakhyolenyng- dan restrains cell adhesion during the restraining period of a blood vessel, I tried to research the effect of Whalakhyolenyng-dan plus Yinsamyangwui-tang on angiogenesis. I made a conclusion putting into operation through using SK-Hep-1 (KCLB 30052), A549(KCLB 10185), AGS(KCLB 21739), and BCE(Bovine Capillary Endothelial Cell). Followings are the results of my experimental research: 1. According to the researching results of anti-cancer activation against cancer cell, Whallkhyoleyng dan plus Yinsamyangwui-tang decreased the number of cancer cells -- While injecting $600{\mu}g/ml$, injected groups decreased 3.1% more comparing with the contrastive group of SK-Hep-1, 49.7% more comparing with the contrastive group of A549, and 31.0% more comparing with the contrastive group of AGS. 2. According to the researching results of DNA composition effect between BCE and cancer cell, Whallakhyoleyng-dan plus Yinsamyangwui-tang reduced the rate of SK-Hep-1 synthesis inhibition by 59.1% at $600{\mu}g/ml$ intensity comparing with contrastive group; for A549, 72.6%; for AGS, 6.1%, for BCE, 28.9%. 3. According to the researching results about the effect of BCE cell to angiogenesis, angiogenesis was restrained at $400{\mu}g/ml$ intensity during 18 hours observation. 4. In the case of aortic ring assay, the half level of angiogenesis was reduced comparing with the contrastive group while injecting with $400{\mu}g/ml$ intensity; with $800{\mu}g/ml$, under 10% comparing with contrastive group; and with $1600{\mu}g/ml$, complete restrain. According to the above results, Whallakhyoleyng-dan plus Yinsamyangwui-tang was proved to have an anti-angiogenetic effects.
