  • We previously showed that the water extracts of rice wine-baked Scutellaria baicalensis Georgi (RWBS) ameliorated colonic inflammation more than crude Scutellaria baicalensis (CS) after oral administration. The aim of this study is to compare the effect of rectal and oral administration of RWBS in the experimental colitis. Experimental colitis was induced in mice by daily treatment with 5% dextran sulfate sodium (DSS) in the drinking water for 7 days. Water was used as vehicle of oral administration, while Carbopol/PEG mucoadhesive gel was used as vehicle of rectal administration. RWBS and RWBS gel (RWBSG) were administered once per day for 7 days. RWBS and RWBSG significantly attenuated the disease activity index (DAI) calculated as the sum of scores of body weight loss, stool consistency and rectal bleeding. Furthermore, RWBS and RWBSG reduced the mucosal myeloperoxidase activity and COX-2 (cyclooxygenase-2) expression in colon tissue. Anti-inflammatory effect of CS on colonic inflammation was increased by baking with rice wine in both oral and rectal administration. Moreover, anti-inflammatory effects of oral administration on colonic inflammation was greater than those of rectal administration. Further study would be required for the development of intra-rectal formulation.

  • Scutellaria baicalensis Georgi has been widely used in China for treatment of various diseases. This study investigated the effect of Scutellaria baicalensis Georgi extracts (SBE) against Coxsackievirus B3 (CVB3)-induced myocarditis in vitro and in vivo. In vitro, Hela cells and primary myocardial cells were infected with CVB3 and treated with SBE ($50-800{\mu}g/ml$) and ribavirin ($200{\mu}M$) for 48 h and then determined by CCK8 assay. Real-time PCR and western blotting assays were performed. In vivo, a myocarditis model was induced in male BALB/c mice by injecting CVB3 suspension intraperitoneally for three times, followed by treatment with SBE (400 and 200 mg/kg) and ribavirin (100 mg/kg) for 28 days. SBE ameliorated the cytotoxicity of CVB3 in Hela cells, especially at $400{\mu}g/ml$ (39.93% vs 65.67%, p < 0.05) without influencing cell growth and also significantly reduced CVB3 replication in primary myocardial cells. The levels of AKT, ERK, and p38 were increased after CVB3 infection. SBE could downregulate the expressions of AKT and p38. In vivo, the mortality rate from CVB3 reached to 66.67%, while 10.00% and 23.33% of this came after 400 and 200 mg/kg SBE treatment, respectively (p < 0.05). The CVB3 replication was obviously reduced after SBE administration from day 5. Similarly, the levels of AKT, ERK, and p38 mRNAs and proteins were increased, and SBE suppressed the expression of AKT and p38. Our study indicates that SBE is a promising potent antiviral agent against CVB3-induced myocarditis by inhibition of virus replication via depressing AKT and p38 expressions.

  • To overcome the limit of morphological method for classification of herbal drug, a novel method to discriminate its origin using pyrolysis mass spectrometry-multivariate analysis was developed. This method was applied successfully to Scutellaria baicalensis Georgi, one of the most popular herbal drug in oriental countries. The ethylacetate soluble fractions were prepared by sonication from pulverized roots of S. baicalensis which were collected from various regions including Korea and China, and subjected to direct insertion probe (DIP) mass spectrometry to achieve mass spectra of pyrolizates of extracts. The probe temperature was elevated from $30^{\circ}C$ to $320^{\circ}C$ at increasing rate $64^{\circ}C/min$, and the average mass spectrum calculated from total ion chromatography (TIC) was obtained. The relative peak intensities versus m/z were subjected to SAS program, and the training set (9 from Korea origin and 22 from China origin) was clustered two groups as its origin. In the test set, 11 samples among total 13 test sample were successfully classified according to their origin by developed method with accuracy of 85%.

  • Scutellaria baicalensis Georgi is one of most important medicinal herbs in traditional chinese medicine. The object of this study was to determine the effects of the water extracts of Scutellaria baicalensis (SB) on the anxiolytic-like activities in the elevated plus-maze (EPM) test. The watεr extracts of SB (100, 200, or 400 mg/kg) were orally administered to male SD rats for 3 days, and behavioral tests for the anxiolytic activity were performed. SB (100, 200, or 400 mg/kg) significantly increased in time-spent and arm entries into the open arms of the EPM compared with the control group. Futhermore, those anxiolytic-like activities of SB were antagonized by flumazenil (a $GABA_A$ antagonist, 3 mg/kg), but not by pindolol (a $5-HT_{1A}$ antagonist, 10 mg/kg). SB did not cause myorelaxant effects in the horizontal wire test at any dosage regimen. Therefore, these findings suggest that SB promote the anxiolytic-like activity mediated by GABAergic nervous system in rats.

  • Objectives : Anti-obesity drugs that have been developed so far have limited efficacies and considerable adverse effects affecting tolerability and safety. Therefore, most anti-obesity durgs have been withdrawn. We tried to develop anti-obesity agent by combinations from herbs that are used in food ingredients as well as in traditional medicines. Methods : The 80% (v/v) ethanol extracts from Bamboo (Phyllostachys pubescence) leaf (BL) and Scutellaria baicalensis (SB) and their 1:1 combination (BLSB) was evaluated on high fat diet induced obese mice compared to Omega-3 as a positive control. The mice were divided into six groups (n=5), one group fed a normal diet (ND), and the others fed a high fat diets for eight weeks. Two weeks after starting feeding the diets, the high fat diet groups were orally administered vehicle and Omega-3, BL, SB, and BLSB at dosage of 200 mg/kg/day for six weeks. All groups were assayed for body weights, food efficiency ratio, blood biochemistry parameters, and organic tissue weights. Results : BLSB group showed significant reductions in body weight gain and fat weights of liver and epididymal adipose tissue compared to BL or SB alone as well as control. Total-cholesterol and LDL-cholesterol levels significantly decreased, and HDL-cholesterol level increased. In liver tissue, macrovesicular steaotisis was remarkably improved and its fat cell size was also significantly decreased. Conclusions : These results suggested that a combination preparation of bamboo leaf and S. baicalensis has anti-obesity effect and have synergistic effect compared to bamboo leaf or S. baicalesis.

  • 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.

  • Background: The objective was to study the effect of Scutellaria baicalensis Georgi ethanol extracts (SBGE) on immune and anti-oxidant function in U14 tumor-bearing mice. Materials and Methods: U14 tumor-bearing mice were randomly divided into eight groups: a control group, a cyclophosphamide (CTX) group, three dose groups of SBGEI (high, medium, low), and three dose groups of SBGEII (high, medium, low). After two weeks, the thymus and spleen weight indices of mice bearing U14 cervical cancer were calculated. Enzyme linked immunosorbent assays (ELISA) was used to determine the levels of serum IL-2, TNF-${\alpha}$, IL-8, and PCNA. MDA activity and SOD activity in plasma were measured with detection kits. Results: In the SBGE groups, thymus weight and spleen weight indices of U14 tumor-bearing mice were significantly higher than in the control group or CTX group (p<0.05). Compared to control group, the levels of serum IL-2 and TNF-${\alpha}$ in U14 tumor-bearing mice increased significantly, whereas the contents of serum IL-8 and PCNA decreased (p<0.05). The activity of SOD increased with the growing dose of SBGE, while the activity of MDA decreased significantly in the highe-rdose groups of SBGE. Conclusions: These findings suggested that SBGE, especially at high dose, 1000 mg/kg, showed significant immune and anti-oxidant effects infU14 tumor-bearing mice, which might be the mechanisms of SBGE inhibition of tumor growth.

  • 황금추출물의 간장기능 회복능을 알아보기 위하여, $CCl_4$로 간중독을 유도한 쥐에게 황금추출물을 급여한 후, 혈액성상, 혈액 내 효소활성치 및 간장 내 전염증성 cytokines의 농도변화를 검토했다. RBC, Hb 및 PCV의 값은 처리군간에 유의한 차이를 나타내지 않았다. 백혈구 총수는 대조군과 비교하여 황금 처리군 모두가 낮은 수치를 나타내었으며, 황금추출물 첨가량이 증가함에 따라 neutrophils 및 eosinophile의 비율이 감소하고, lymphocytes 및 monocytes의 비율이 증가하였다. basophils의 구성비는 처리군 별 유의한 차이를 나타내지 않았다. Total protein 농도 및 albumin 농도는 처리군 간에 유의한 차이를 나타내지 않았다. 그러나 albumin/globulin 농도 비율은 대조군보다 황금추출물 처리군에서 높았다. GOT, GPT 및 LDH의 효소활성치들은 모두가 대조군보다 황금추출물 처리군에서 낮은 수치를 나타내었으며, 황금추출물 첨가량이 증가함에 따라 하락하는 경향을 보였다. 간장 내 IL-$1{\beta}$, IL-6 및 TNF-$\alpha$의 농도는 대조군보다 황금추출물 처리군 모두가 낮은 값을 나타내었으며, IL-10의 농도는 대조군보다 황금추출물 처리군 모두가 높은 값을 나타내었다. 이상의 결과를 종합해 보면 황금추출물은 간장기능회복에 효과를 나타내는 기능성 물질을 내재하고 있음을 시사해 준다.
