  • Scutellaria baicalensis Georgi. (SBGE) is known to be antioxidant effect. In addition of the effects, we further investigated the SBGE on the antioxidant effect on a renal cortical slices cell and kidney protecting effects. The results were as follows. 1 When renal cortical slices separated from a rabbit's kidney were treated with 1mM tert-Butylhydroperoxide (t-BHP) in the presence of SBGE. SBGE significant prevented t-BHP induced increase in lactate dehydrogenase (LDH) release and lipid peroxidation. 2. When renal cortical slices separated from a rabbit's kidney were treated with oxidant $300{\mu}M$ cisplatin in the presence of SBGE. SBGE significant prevented cisplatin-induced increase in LDH release and lipid peroxidation. 3. Pretreatment with 0.1g/kg SBGE for seven day and treatment with 5 mg/kg cisplatin by the intraperitoneal injection The results were that the pretreatment group with SBGE showed a significant decrease in lipid peroxidation, increase in clearance rate of blood urea nitrogen (BUN) and creatinine in the kidney than the administering single agent group of cisplatin. and pretreatment group with SBGE showed intact microvillus of proximal tubule and no contraction of rumen, it was a similar result with normal group. With the results SBGE showed to be highly effective on antioxidant effect and cellular protection activity against cisplatin that was a toxic agent on a kidney. Therefore, SBGE is considered to have protective effective on a disordered kidney or kidney diseases such as nephritis or renal failure that cause tissue damages in a kidney.

  • In our study, as many as 29 edible medicinal herbs were selected for testing their ability in the effective treatment of gout based on oriental medicine theory. We extracted each medicinal herb (135 g) with 4 L of distilled water at $100{\sim}105^{\circ}C$ for 210 min. Thereafter, we evaluated both the antioxidant and xanthine oxidase inhibition activities of the extracts obtained. Among all the edible medicinal herbs used in our study, only the extract from Scutellaria baicalensis Georgi (Korean name: hwang-geum) showed (1) the maximum total phenolic content (TPC) (2.25 mg gallic acid equivalent/mL), (2) DPPH radical scavenging activity (94.04%), and (3) xanthine oxidase inhibition activity (87.75%). We also observed that TPC was relatively highly correlated with both the DPPH radical scavenging activity (r=0.63) and xanthine oxidase inhibition activity (r=0.77). Our results suggest that S. baicalensis G. may be a potent antioxidant source for the extraction and development of nutraceuticals that may be utilized for effective treatment of gout.

  • The ether, ethylacetate and n-butanol soluble fractions from the roots of Scutellaria baicalensis showed a significant inhibition of lens aldose reductase (AR) activity in vitro. During systematic fractionation of the active fractions, 7 flavonoids were isolated and compared their inhibitory activities against rat AR using DL-glyceraldehyde as a substrate, among which baicalin (VII) was found to exhibit the most potent inhibitory activity. Baicalin (VII) and wogonin-7-O-glucuronide (VI), with repeated treatments (30 mg/kg/day, i.p.) throughout the experimental periods caused a significant suppression of cataract formation induced by galactose (40 g/kg/day) as well as the decrease of galactitol accumulation in the rat lens. The flavonoids also exhibited a significant inhibition of sorbitol accumulation in the lenses of diabetic rats induced by streptozotocin (STZ).

  • 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.

  • Scutellaria baicalensis GEORGI(SB) is used in oriental medicine for the treatment of incipient strokes. Although it has been reported that SB is neuroprotective in a hypoxia model, its mechanism is poorly understood. Here, we investigated the effect of SB on the modulation of retinoic acid receptor a (RARa). Rat cerebrocortical cells were grown in neurobasal medium. On DIV12 cells were treated with SB $(20{\mu}g/ml)$ and given a hypoxic shock $(2%\;O_2/5%\;CO_2,\;3hr)$ on DIV14. In situ hybridization using cRNA probe revealed that RARa mRNA punctae are distributed, in addition to nucleus, throughout neuronal dendrites, where SB upregulated its density by 69.8% (p=0.001) and 129.8% (p=0.001) in both normoxia and hypoxia, respectively. At the protein level, SB upregulated RARa in the neuronal soma by 78.8% (p=0.004) and 23.6% (p=0.001) in both normoxia and hypoxia, respectively. These results indicate that SB upregulates RARa in both normoxia and hypoxia, which might contribute to the neuroprotection.

  • Objectives: cDNA microarray is an effective method to snapshot gene expression. Functional clustering of gene expressions can identify herbal medicine mechanisms. Much microarray data is available for various herbal medicines. This study compares regulated genes with herbal medicines to evaluate the nature of the drugs. Methods: Published microarray data were collected. Total RNAs were prepared from dissociated hippocampal dissociate cultures which were given hypoxic shock in the presence of each herbal medicine. Up- or downregulated genes higher than Global M value 0.5 were selected, clustered in functional groups, and compared with various herbal treatments. Results: 1. Akt2 was upregulated by Acorus gramineus SOLAND, Arisaema amurense var. serratum $N_{AKAI}$ and Coptis chinensis $F_{RANCH}$, and they belong to Araceae herb. 2. Nf-${\kappa}b1$, Cd5, $Gn{\gamma}7$ and Sgne1 were upregulated by Arisaema amurense var. serratum $N_{AKAI}$, Coptis chinensis $F_{RANCH}$ and Rheum coreanum $N_{AKAI}$. 3. Woohwangcheongsim-won, Sohaphyang-won and Scutellaria baicalensis $G_{EORGI}$ downregulated Scp2 and upregulated Tsc2. Woohwangcheongsim-won and Sohaphyang-won upregulated Hba1 and downregulated Myf6. 4. Sohaphyang-won and Scutellaria baicalensis $G_{EORGI}$ downregulated Slc12a1. 5. Woohwangcheongsim-won and Arisaema amurense var. serratum $N_{AKAI}$ upregulated $Rar{\alpha}$, Woohwangcheongsim-won and Coptis chinensis $F_{RANCH}$ downregulated Rab5a and $Pdgfr{\alpha}$, and Woohwangcheongsim-won and Rheum coreanum $N_{AKAI}$ upregulated $Plc{\gamma}1$ and downregulated Pla2g1b and Slc10a1. Conclusions: By clustering microarray, genes are commonly identified to be either up- or downregulated. These results will provide new information to understand the efficacy of herbal medicines and to classify them at the molecular level.

  • Scutellaria baicalensis G. was cultivated in plots of different soil textures which were sand loam(SL), loam(L) and clay loam(CL). Also three fertilizer conditions were used; non application (NA)treatment, rice straw manure(RSM) treatment and N-P-K, chemical fertilization(CF) treatment. The chemical-physical properties, such as organic matter, available phosphate, $K_2O$, CaO, clay contents and porosity ratio in CL plot with RSM application were the most proper in CL plot and RSM application for the culture of S. baicalensis plants. RSM had very high contents of total nitrogen, 2.25% and C/N ratios, 21.4. Thus the growth of shoot and root in loam plot with RSM treatment were greater compared to that of CL plot with NA treatment. Whereas, The highest baicalin, baicalein and wogonin contents in roots were found in CL plot with RSM treatment. There was significantly positive correlation between aerial and underground parts of plant, yield and contents of T-N, $K_2O$ but negatively correlated with the contents of baicalin, baicalein and wogonin in S. baicalensis roots.

  • Chemical preservatives have a good effect on antibacterial activity, but many side effects on the human body have been reported. Recently, the development of natural preservatives that are harmless to the human body and have preservative functions and self-efficacy is active. In addition, in order to increase the absorption rate of natural products by the human body, the method of fermentation using strains is also increasing. Therefore, this study selected varieties that are harmless to the human body and have good antibacterial activity. 1. The yield of origin, thickness and solvent was investigated. Scutellaria baicalensis Georgi was made in China and received a yield of 21.88% from 50% ethyl alcohol extract. Salvia miltiorrhiza Bunge was made in Korea and received a yield of 25.62% from 50% ethyl alcohol extract. Dryopteris crassirhizoma Nakai was made in China and received a yield of 6.50% from 70% ethyl alcohol extract. 2. The solid fermentation with the S. baicalensis and S. miltiorrhiza with B. Subtilis yield gained 24.40%, 39.30%, and D. crassirhizoma obtained 11.10% yield when fermented with L. casei. 3. After the liquid fermentation, a clear zone of 9mm was identified for the S. aureus strain in the S. baicalensis, and the antibacterial activity was not confirmed in S. miltiorrhiza and D. crassirhizoma. 4. When the S. baicalensis was fermented with L. Casei, it showed high antibacterial activity in C. albicans and S. aureus. S. miltiorrhiza showed antibacterial activity in S. aureus when it was solid with S. cerevisiae. When the spectators were solid with L. casei and S. cerevisiae, antibacterial activity was high in E. coli and S. aureus. Overall, the antibacterial activity after fermentation was much higher than when fermented. 5. The change in active ingredients was baicalin 101.57, baicalein 28.26, and wogonin 5.33mg/g in the S. baicalensis that did not ferment solid. When solid fermentation with S. cerevisiae, the content of baicalinin with baicalin 94.31, baicalein 30.41, and wogonin 3.57mg/g was found to have increased. S. miltiorrhiza that was not fermented, salvianolic acid A was 1.82mg/g, and when fermented with S. cerevisiae, it increased to 5.70mg/g. The active ingredients of the spectators were flavaspidic acid AP, flavaspidic acid PB, flavaspidic acid AB, and flavaspidic acid BB.

  • The antioxidant activities of ethanolic extracts obtained from medicinal plants (Scutellaria baicalensis Georgi, Acanthopanax sessiliflorum Seeman, Pueraria lobata Ohwi, Portulaca oleracea Linne, Crataegus pinnatifida Bunge var. typica Schneider, Euonymus alatus Apterus, Hovenia dulcis Thunberg, Prunus yedoensis Matsumura, Albizzia julibrissin Durazz., Chrysanthemum indicum Linne) were evaluated for total phenolic content, total flavonoid content, DPPH radicals, nitrites, $Superoxide^-$ radicals, $ABTS^+$ radical scavenging activity, and reducing power. Antioxidant capacities were the highest in Prunus yedoensis Matsumura for DPPH radical scavenging activity ($IC_{50}$ $5.39{\mu}g/mL$), reducing power (2.72, $A_{700}$), and nitrite scavenging activity ($IC_{50}$ $167.94{\mu}g/mL$). Hovenia dulcis Thunberg and Acanthopanax sessiliflorum Seeman were effective for their nitrite scavenging activities (over 90% at 1 mg/mL). The $Superoxide^-$ radical scavenging activity of Prunus yedoensis Matsumura ($IC_{50}$ $43.39{\mu}g/mL$) was stronger than tannic acid ($IC_{50}$ $46.51{\mu}g/mL$). Five samples (Prunus yedoensis Matsumura, Acanthopanax sessiliflorum Seeman, Hovenia dulcis Thunberg, Crataegus pinnatifida Bunge var. typica Schneider, Scutellaria baicalensis Georgi) were effective for their $ABTS^+$ radical scavenging activity (more than 90% at 0.5 mg/mL). These results suggest that the ethanolic extracts of Prunus yedoensis Matsumura could be used as a functional ingredient in food products.
