Nitric oxide is involved in various physiological processes. Among isoforms of nitric oxide synthase, iNOS is partly responsible for inflammation and septic shock. During our continual search for anti-inflammatory flavonoids, we have found that flavonoids, especially flavones, possessed the inihibitory activity of NO production by iNOS from LPS-activated RAW 264.7 cell. In this study, flavonoids from Scutellaria radix were investigated for their inhibitory activity of nitric oxide production. It was found that wogonin, among tested flavonoids including baicalein, oroxylin A, skullcapflavone II, showed the strongest inhibition of nitric oxide production (IC$\sub$50/ = 17 uM). And this inhibition was, at least partly, due to down-regulation of iNOS enzyme induction, not due to direct inhibition of iNOS enzyme activity.

In many cases of human cancer, the appearance of hypersialylated glycan structures is related to a precise stage of the disease ; this may depend on the elebated sialyltransferase activity during carcinogenesis. The aim of this study was to investigate the inhibitory effects of Oriental medicinal herbs on enzymatic activities of two kinds ofsialyltransferase, Gal $\beta$ 1,3GalNAc$\alpha$2,3-sialyltransferase(ST3Gal I) and Gal $\beta$ 1,4GlcNAc $\alpha$2,6-sialyltransterases(ST6Gal I), which are well known as glycosyltransterases associated with cancer. The aqueous extracts of Scutellaria Baicalensis Georgi, Coptidis Rhizoma, Glycyrrhiza urlensis Fisch, Bupleuri Radix and Platycodi Radix were prepared and tested, respectively. At concentration of 100$\mu$g, Glycyrrhiza uralensis Fisch showed the highest inhibitory effects(about 42% and 57%, respectively) on ST3Gal Iand ST6Gal Iactivities. ST3GAl I was inhibited about 23% by Scutellaria baicalensi G댁햐, but not by the other samples, whereas ST6Gal I was inhibited about 20% and 40%,respectively, by Scutellaria baicalensis Georgi and Bupleuri Radix. All inhibitory effects were obtained in a concentration-dependent manner.

Objectives : Categorized as 'cheongyeol' herbs, Herba Prunellae, Flos Lonicerae and Radix Scutellaria have been proven to have effect on degenerative brain disease, cerebrovascular disease and brain tumor because of their anti inflammation, antioxidant, or anticancer effects. In this study, we studied activity against reactive oxygen species and anti inflammation effect of these three 'Cheongyeol' herbs. Methods : We measured each herb's yield of ethanol extracts, phenolic contents and activities against DPPH, hydroxyl radical and superoxide anion. Also through 6-hydroxydopamine (6-OHDA) induced oxidative damage in SH-SY5Y human neuroblastoma cell line, we measured antioxidant effect and NO activity of the three herbs. From the three herbs, we chose Prunella Herba, which showed the highest antioxidant effect, and studied its cell survival rate and anti inflammation effect through COX-2 and iNOS. Results : All three herbs showed significant results, and especially Prunella Herba showed significant effect on phenol contents, antioxidant effect on various active oxygen and antioxidant, and anti inflammation effect through cell line. Conclusions : Further study of the origin concept of 'cheongyeol' and research into specific mechanisms and role in treatment of cranial nerve disease, seems warranted.

objective : The purpose of this research is to examine the effects of Scutellaria Radix(SR) extract on immune cells and cytokines in ovalbumin(OVA)-induced asthmatic mice. Methods : In vivo, C57BL/6 mice were sensitized and handicapped by OVA for 9 weeks. In this experiment, one group was not treated, and the other group was treated with SR extract for six weeks(five times per week) and analyzed by ELISA and flow cytometer. Results : In vivo, there were significant decreases in eosinophils, IL-4, IL-13 in BALF (bronchoalveolar lavage fluid) compared with that of control group. However,$IFN{\gamma}$ in the SR group increased significantly compared with that of control group. Additionally, the population of $CD3e^-/CCR3^+,\;CD69^+/CD3e^+,\;IgE^+/B220^+,\;CD11b^+/Gr-1^+$ cells in the SR group decreased compared with that of control group. conclusion : The results of this study support a role for SR as an effective treatment for asthma in its experimental success in significantly decreasing inflammation and asthma reactions, and in increasing $IFN{\gamma}$, Which helps prevent such reactions.

Carbon tetrachloride $(CCl_4)-induced$ liver injury depends on a toxic agent that has to be metabolized by the liver NAPDH-cytochrome P450 enzyme system to a highly reactive intermediate. Although several isoforms of cytochrome P450 may metabolize $CC1_4$, attention has been focused largely on the cytochrome P450 2E1 (CYP2E1), which is ethanol-inducible. Alternations in the activity of CYP2E1 affect the susceptibility to hepatic injury from $CC1_4$. In this study, the liver protective effect of the hot water extracts of Scutellaria radix (SR) was investigated. The SR exhibited a hepatoprotective activity against $CCl_4-induced$ liver damage in Chang liver cells. The expression of CYP2E1, measured by RT-PCR and Western blot analysis, was significantly decreased by SR treatment in Chang cells. Based on these findings, it is suggested that hepatoprotective effect of SR possibly related to downregulation of CYP2E1 expression.

This study was designed to investigate the effect of medicinal herb extract on the antioxidant and antimicrobial activities against Helicobacter pylori, which is known as a ulcerogenic pathogen. The concentration of total phenolic compound of Scutellaria baicalensis(13.14%) was highest among water extracts and that of Ulmus parvifolia(15.12%) was highest among the ethanol extracts. The antioxidant activity of the water extract of Scutellaria baicalensis and of the ethanol extract of Ulmus parvifolia were 91.00% and 65.03%, respectively, in DPPH assay. The antioxidant activity of the water extract of Scutellaria baicalensis and of the ethanol extract of Ulmus parvifolia were 32.90% and 27.70%, respectively, in SOD assay. The antioxidant activity of the water extract of Ulmus parvifolia and of the ethanol extract of Glycyrrhiza uralensis Fischer was 2.15 and 2.17, respectively, in TBARS assay. In disc method, Scutellaria baicalensis showed the highest anti-microbial activity against H. pylori, followed by Glycyrrhiza uralensis Fischer among the water extracts and Glycyrrhiza uralensis Fischer showed the highest anti-microbial activity followed by Radix puerariae among ethanol extract.

한약재로 수요가 많고 꽃이 아름다워 화훼용으로 개발 가능성이 있는 황금을 활성탄을 사용하여 분화재배를 실시할 경우 꽃의 수명이 오래가고 수확시 품질이 양호한 한약재를 생산 할 수 있을 것으로 기대되어 본 시험을 수행 한 결과는 다음과 같다. 1. 황금의 생장은 활성 탄(Activated Charcoal) 30%가 첨가되었을때 경장과 경태가 크고 가지수가 많아 생육이 가장 양호하였다. 2. 황금의 개화는 각 처리 공히 90%이상이 개화되었다. 3. 수량은 활성탄(Activated Charcoal)이 30%첨가되었을 때 생육이 양호하여 근경과 근장이 크고 근중이 무거워서 증수되는 경향이었다. 이와 같은 이유는 활성탄 시용에 의한 토양의 보수력과 보비력이 양호하여 물리성이 향상된 것으로 생각되며 이보다 더 낮은 농도나 높은 농도에서는 효과가 적은것으로 나타났다. 이상과 같은 결과로 보아 황금을 재배할 경우 활성탄(Activated Charcoal)의 효과가 인정되어 약초의 종류에 따른 농도별 시험이 계속적으로 이 루어 져야 할 것으로 사료된다.

Scutellariae Radix has been used as a traditional medicine for anti-oxidant, anti-inflammatory, anti-allergic function. But most study methods were restricted to in vitro and in vivo. Therefore to perform for clinical trials further for a new natural drug development is necessary and this study will be used as a basis for it. The studies selected from domestic academic database included the following key words; '황금', '黃芩', 'skullcap', 'Scutellariae Radix', 'scutellaria baicalensis' and considered were those published from 1990 to July, 2011. All 1080 studies were found to include the keywords related to the study subjects either in their title of contents or abstracts. and 298 studies were finally selected as subjects for this study. 243 studies among 293 studies were published between 2000 to 2011. Classification was proceeded according to study subjects as followed; anti-Inflammatory effect and antiallergic and antihistamin effect(66), antibacterial and antivirus effect(61), antioxidant effect(51), neuronal cell apoptosis and neuronal cell protective effect(22), liver cell protective effect(20).
