Objectives : To investigate the anti-inflammatory effects of Scutellaria baicalensis Georgi pharmacopuncture in lipopolysaccharide (LPS)-induced inflammatory rat model. Methods : Sprague-Dawley rats were divided into 4 groups; LPS control (n=6), LPS+Scutellaria baicalensis Georgi pharmacopuncture at BL23 (n=6, BL23), LPS+Scutellaria baicalensis Georgi pharmacopuncture at CV12 (n=6, CV12), and LPS+Scutellaria baicalensis Georgi pharmacopuncture at GV4 (n=6, GV4). Pharmacopuncture was given every two days for 4 weeks followed by inflammation induction by intraperitoneal LPS injection (5mg/kg). Blood, liver tissue, and peritoneal lavage fluid were taken and proinflammatory cytokines and other related factors were analysed. Results : For proinflammatory cytokines, CV12 pharmacopuncture group was significantly different compared with the control group in plasma IL-$1{\beta}$, IL-6, TNF-$\alpha$, and IL-10 5 h after LPS injection (P<0.05). For plasma IL-$1{\beta}$ and IL-6, CV12 pharmacopuncture group also showed significant difference at 2 h compared with the control (P<0.05). GV4 pharmacopuncture group was significantly different compared with the control at 5 h in plasma IL-$1{\beta}$, IL-6, and TNF-$\alpha$ and at 2 h in IL-10 (P<0.05). Liver cytokines were analyzed at 5 h after LPS injection; only CV12 pharmacopuncture group showed significant difference in IL-$1{\beta}$ (P<0.05) and others including IL-6, TNF-$\alpha$, and IL-10 had no difference compared with the control group. CD4/CD8 ratio and the phagocytic activities of polymorphonuclear neutrophils were not different from those of control group in all pharmacopuncture groups (P>0.05). Plasma NO3-/NO2- and intracellular adhesion molecule-1 of CV12 pharmacopuncture group were significantly lower than that of the control group (P<0.05). In the plasma concentration of prostaglandin E2, all 3 pharmacopuncture groups had significantly lower values than that of the control group (P<0.05), but there was no difference among pharmacopucnture groups. Monocyte chemoattractant protein-1 and cytokine-induced neutorphil chemoattractant-1 in peritoneal lavage fluid was significantly decreased in CV12 pharmacopuncture group compared with the control group (P<0.05). Conclusions : These results indicate that Scutellaria baicalensis Georgi pharmacopuncture at CV12 may have a potent anti-inflammatory effect in an LPS-induced inflammatory rat model.

This research was carried out to find the dyeing properties of Scutellaria baicalensis Georgi on the rayon and cotton fabrics. The best proper dyeing conditions were examined by changing dye concentrations, dyeing temperature, dyeing time, and dyeing repitition. Also dyeability and surface color changes were evaluated by various mordanting methods and agents. The maximum absorption of Scutellaria baicalensis Georgi were at 275nm and 362nm. The optimum dyeing conditions on the cotton were 80%, $80^{\circ}C$, 40minutes, 4 repitition, and those on the rayon were 80%, $80^{\circ}C$, 60minutes, 5 repitition. The K/S values of rayon and cotton fabrics were higher in pre-mordant than post-mordant. The K/S values on the rayons were lower than no mordant fabric except pre-Fe mordant, these on the cotton fabrics were higher than no mordant fabric except post-Al mordant. The value of ${\Delta}E$ was the highest in Fe mordanted fabrics, and higher on the cotton fabric than rayon. The surface colors of all mordanted fabrics were yellow.

Scutellaria baicalensis Georgi, which has been known to be able to clear away heat and remove dampness, was used for febrile disease. It is now clear that Advanced glycation end products (AGEs) play major roles in the pathogenesis of diabetic complications such as atherosclerosis. In this study, we examined whether Scutellaria baicalensis Georgi suppress the AGE mediated inflammatory responses in the THP-1 cells. AGE treatment increased the gene expression of pro-inflammatory cytokines such as tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), interleukin-$1{\beta}$ (IL-$1{\beta}$), monocyte chemotactic protein-1 (MCP-1) and cyclooxygenase-2 (COX-2). Reverse transcriptase-polymerase chain reaction and Western blot analysis revealed that S. baicalensis had inhibitory effects on the expression of pro-inflammatory genes and protein levels in AGE-treated THP-1 cells. S. baicalensis had also reduced the production of ROS in the AGE-treated THP-1 cells. These results suggest that S. baicalensis has inhibitory effects for the development of diabetic vascular complication.

Flavonoid production by suspended cells of Scutellaria baicalensis Georgi was studied and the medium was optimized for cell growth and baicalin production. In SH medium the flavonoid production was not closely associated with the cell growth. A modified SH medium, FPM, was therefore designed for enhanced baicalin production. In FPM, both cell growth and baicalin production were increased by 1.5 times and 1.67 times than in the original SH medium, respectively. The increases could be attributed to the increased metabolic activities involved in the flavonoid biosynthesis as represented by enhanced activities of phenylalanine ammonia-lyase.

This study was conducted to investigate the antibacterial, antioxidant, and in vitro greenhouse gas mitigation activities of fermented Scutellaria baicalensis Georgi extract. Seven starter cultures were used, comprising four of lactic acid bacteria and three of Saccharomyces cerevisiae. Ten grams of S. baicalensis Georgi powder was diluted in 90 mL autoclaved MRS broth. Each seed culture was inoculated with 3-10% (v/v) S. baicalensis Georgi MRS broth and incubated at $30^{\circ}C$ for 48 h. Among the starter cultures used, only Lactobacillus plantarum EJ43 could withstand the fermentation conditions. This fermentation broth was dried and extracted with ethanol to assess its antibacterial, antioxidant, and in vitro methane mitigation activities. The extract of S. baicalensis Georgi fermented by L. plantarum EJ43 (SBLp) showed higher antibacterial activity (bigger clear zone) compared to the unfermented S. baicalensis Georgi extract (SB0). SBLp also presented 1.2 folds higher antioxidant activity than SB0. During in vitro rumen fermentation, SBLp showed reduction in methane production compared to SB0 or the control. In conclusion, fermentation by L. plantarum EJ43 may enhance antibacterial and antioxidant activities of S. baicalensis Georgi and decrease enteric methane production.

GATA-binding protein-3 (GATA-3) and T-box expressed in T-cells (T-bet) are now considered as master transcription factors involving Th cell differentiation, but the roles of these factors are still uncertain in vivo. This study was conducted to investigate the expression of these transcription factors in the liver damage induced by carbon tetrachloride ($CCl_4$) in rats. In this study, liver damage were induced with Scutellaria baicalensis Georgi water extracts (SBW) and followed for 4 weeks. The expression of GATA-3 and T-bet protein in liver damage induced by $CCl_4$ and the serum levels of immunoglobulin A (IgA), IgE were studied after 4 weeks of treatment. We found that effect of SBW on IFN-$\gamma$, STAT1, pSTAT1 and T-bet was decreased in vivo. Several genes were demonstrated to be IL-4 inducible prior to the discovery of STAT6. $CCl_4$+SBW group was significantly lower than $CCl_4$ group in IL-4, STAT6, pSTAT6 and GATA-3. Our data indicate that cytokine protein production were increased in $CCl_4$ group and $CCl_4$+SBW group. From these results, water extracts obtained from Scutellaria baicalensis Georgi may have an immunoregulatory effect in the liver induced by $CCl_4$ of rats.

An ethanolic extracts of Scutellaria Baicalensis GEORGI are used to treat cancer, infectious diseases, and inflammation. In the present study, we investigated the effects of an ESBG on the growth and survival of 5637 cells, a human bladder carcinoma cell line. Cells were treated with different concentrations of an ethanolic extract of Scutellaria Baicalensis GEORGI (ESBG), and cell death was assessed using a MTT (3-[4, 5-dimethylthiazol-2-yl]-2, 5-diphenyltetrazolium bromide) assay. Analyses of the sub G1 peak, caspase-3 and -9 activities, and mitochondrial membrane depolarizations were conducted to confirm cell death by apoptosis. ESBG had a cytotoxic effect on 5637 cells, and increased the sub G1 peak, caspase-3 and -9 activities, and mitochondrial depolarization, indicating ESBG induced apoptosis. Furthermore, MAPK (mitogen-activated protein kinases) inhibitors suppressed this apoptosis. In an in vitro study, a combination of sub-optimal doses of ESBG and paclitaxel, 5-fluorouracil, or docetaxel noticeably suppressed tumor growth by 5637 cells. Our findings provide insight of the mechanisms underlying cellular apoptosis induced by ESBG, and suggest new therapeutic strategies for bladder cancer.
