Objectives: Alcoholic fatty liver is a potentially pathologic condition which can progress to steatohepatitis, fibrosis, and cirrhosis. The objective of this study is to investigate the effects of Scutellaria Radix (SR) extract on the alcoholic fatty liver induced by long-term EtOH administration. Results: Male Sprague Dawley rats were used in this study. All animals were randomly divided into Normal group, treated with saline (n=10); EtOH group, treated with ethanol (n=10); EtOH+SR group, treated with ethanol+Scutellaria Radix extract (n=10). For oral administration of ethanol in EtOH and EtOH+SR group, the ethanol was dissolved in distilled water in concentrations of 25% (v/v). Throughout the experiment of 8 week, the rats were allowed free access to water and standard chow. Sample group were administrated by Scutellaria Radix extract daily for 8 weeks. Results: The levels of hepatic marker such as aspartate aminotransferase and alanine aminotransferase were altered. Histopathological changes such as ballooning, fatty and hydropic degeneration were reduced and the expression of tumor necrosis $factor-{\alpha}$ ($TNF-{\alpha}$) was significantly attenuated by Scutellaria Radix extract. Conclusions: These data suggest that Scutellaria Radix extract attenuated the alcoholic simple fatty liver by improving hepatic lipid metabolism via suppression of $TNF-{\alpha}$ protein. Scutellaria Radix could be effective in protecting the liver from alcoholic fatty liver.

The purpose of this study was to evaluate the effects of ethanolic extracts of Scutellaria Radix on the alveolar bone formation in the extract socket of rat. Thirty-six Sprague-dawley rats were used in this study. Mean body weight of rat was $130{\pm}5g$. Experimental animal were administered 0.4% ,${\beta}-aminopropionitril$(Sigma, USA) with the solid commercial food for 5 days. All the maxillary 1st molar of the rats were extracted by using of the tissue forcep under the general anesthesia with Pentobarbital sodium(Tokyo Chemical Co, Japan) injection into intraperitoneal space. All the extracted rats were divided into two group, experimental group which were feeded the solid food mixed ethanolic extracts of Scutellaria Radix, and control group which were feeded same food without reagent. At 1, 3, 5, 7, 9 and 14th days after tooth extraction, rats in both groups were serially sacrificed respectively. All the specimen were treated as usual method and prepared Hematoxylin-eosin stain for the light microscopic observation. The results were as follows : 1. Bone formation of extracted socket starts from the area on remained periodontal ligament than other area. 2. In the case of administration of the extracted Scutellaria Radix showed rapid healing process of connective tissue than non-administrated group. 3. In the case of administration of the extracted Scutellaria Radixshowed rapid osteogenesis than non-administrated With above results, it was concluded that ethanolic extracts of Scutellaria Radix may play a favorable role on the healing process of exatraction socket after extraction in rats. It was suggested that further study to evaluate the different concentration and administration method of ethanolic extracts of the Scutellaria Radix into same experimental model.

Microwaves are non-ionizing electromagnetic waves of frequency between 300MHz to 300GHz and positioned between the X-ray and infrared rays in the electromagnetic spectrum. In recent years, the use of microwave for extraction of ingredient from plant material has shown remarkable research interest and potential. Scutellaria radix has been used as a traditional medicine for a variety of diseases. It has been reported to exert beneficial health effects, such as anti-bacterial, antiviral, anti-inflammatory, and free-radical scavenging. Oxidative stress or the accumulation of reactive oxygen species (ROS) leads neuronal cellular death and dysfunction, and it contributes to neuronal degenerative disease such as Alzheimer's disease, Parkinson's disease and stroke. In this study, we aimed to compare the neuroprotective and antioxidant effect of Scutellaria radix extracted by different methods using hot-water extraction (SBE-DW) or microwave extraction (SBE-DW-MW). As a result, we first examined HPLC analysis of hot-water and microwave extracts of Scutellaria radix. The hot-water and microwave extracts of Scutellaria radix showed the discernible difference patterns of HPLC analysis. Microwave-water extracts of Scutellaria radix increased DPPH radical scavenging activity more than hot-water extraction. Microwave-water extracts of Scutellaria radix also showed neuroprotective effects and ROS inhibition against glutamate-induced oxidative stress in mouse hippocampal HT22 cells, but hot-water extraction not showed. In addition, the phosphorylation of MAPKs induced by glutamate insult was prevented by microwave-water extracts of Scutellaria radix. Thus, these results suggested that microwave extraction can be utilized for improving the extraction efficiency and biological activity of Scutellaria radix.

Sam-Hwang-Sa-Shim-Tang(SHSST), a traditional Chinese medicine, composed of Rhei rhizoma, Scutellaria radix, and Coptidis rhizoma were used in the several disease including hypertension, constipation, and hemorrhage. In the present study, we investigated the neuroprotective effects of SHSST and its ingredients on the ischemia/ reperfusion-induced brain injury was evaluated in the rat brain. Ischemia was induced by intraluminal occlusion of the right middle cerebral artery for 120 min and reperfusion was continued for 22 h. SHSST (450 mg/kg), Rhei rhii oma (100 mg/kg), Coptidis rhizoma (100 mg/kg), and Scutellaria radik (100 mg/kg) were orally administered twice, promptly prior to reperfusion and 2 h after the repefusion. Total infarction volume in the ipsilateral hemisphere of ischemia/ reperfusion rats was significantly lowed by the treatments of SHSST (39.2%) and Scutellaria radix (66.5%). However, Coptidis rhizoma did not show any significant effects on the total infarct volume. The inhibiting effect of Scutellaria radix on the total infarct volume was more potent than that of SHSST. In addition, Scutellaria radix significantly inhibited myeloperoxidase (MPO) activity, an index of neutrophil infiltration in ischemic brain tissue. However, there was marked mismatch between total infarct volume and MPO activity in the Scutellaria radix-treated rats. Our findings suggest that Scutellaria radix as an ingredient of SHSST plays a protective role in ischemia-induced brain injury by inhibiting neutrophil infiltration. The effects of Rhei rhizoma on transient brain ischemia-induced neuronal injury are under study.

In the present study, wogonin, a major flavone isolated from Scutellaria Radix were examined for its imunosuppressive activity on the 2,4-dinitro-fluorobenzene (DNFB)-induced delayed type hypersensitivity (DTH) in C3H/HeN mice. This compound inhibited selectively $TNF-\alpha$ and IL-4, but not IL-6, IL-10 and $IFN-\gamma$ on DNFB-induced Th1 and Th2 cytokines in a concentration-dependent manner. Interestingly, this compound increased the expression of heme oxygenase-1 (HO-1) in a concentration-dependent manner The above results reveal that wogonin possesses anti-inflammatory, humoral and cellular immunomodulatory, and stress reducing activities on the DNFB-induced DTH in mice and these properties may contribute to the anti-atopic dermatitis activity of Scutellaria Radix.

Scutellaria Radix, originated from Scutellaria baicalensis Georgi, is one of the most important medicine in traditional Oriental medicine, and possesses anti-bacterial activity and sedative effects, can be applied in the treatment of a range of conditions including diarrhea and hepatitis. It is reported that chronic global ischemia induces neuronal damage in selective, vulnerable regions of the brain, especially the hippocampus and cerebral cortex. In the present study, to investigate the effect of Scutellaria Radix extract on cerebral disease, the changes of regional cerebral blood flow and pial arterial diameter on ischemia/reperfusion state was determinated by Laser-Doppler Flowmetry and some parameters concerned with oxidative stress also measured. When SRe were administered for five days with the concentration of 100 mg/kg, GSH activity significantly increased. But SRe administeration showed no significant change in lipid peroxidation. When the activities of CAT, Cu, Zn-SOD and GSH were measured, CAT and GSH were activated by SRe administration. When 1 and 3 ㎍/㎖ SRe was applied to the neuronal cell cultures, the quantities of LDH was significantly reduced when compared with cultures treated only with NMDA. Through this study, it can be concluded that the ischemia/reperfusion induced brain stress may have contributed to cerebral damage in rats, and the present study provides clear evidence for the beneficial effect of SRe on ischemia induced brain injury.

Scutellaria baicalensis $G_{EORGI}$ (Scutellariae Radix) has been used to clear heat and to dry dampness in the stomach or intestines, which manifests as diarrhea or dysenteric disorder. In this study, we investigated the effective preparation of active components in Scutellariae Radix using the methods of solvent extraction and absorption fractionation for the development of new functional food or pharmaceuticals. The marker substances, baicalin, baicalein, wogonoside, and wogonin were directly isolated from the Scutellariae Radix. There chemical structures were elucidated by spectroscopic analysis. The Scutellariae Radix was extracted with hot water. To enhance yield of flavonoids in Scutellariae Radix, the hot water extract was dissolved in ethanol with concentration dependent manner. The precipitates were separated using centrifugal techniques at 10,000 rpm. Supernatant liquid was applied to the HPLC for quantification of major compounds. Separately, the hot water extract was absorbed on Diaion HP-20 resin. And then, the absorbed fraction was eluted with methanol for HPLC. The contents of baicalin, baicalein, wogonoside and wogonin in different treatment methods were analyzed by HPLC. Total amount of four major components were 16.9% in 50% ethanol extract, 21.7% in 70% ethanol extract, 20.5% in 90% ethanol extract, and 39.3% in absorbed fraction of Diaion HP-20 resin. In these results, we found that resin absorption method is suitable for the extraction of enriched flavonoids from Scutellariae Radix.

The initiation of immunoglobulin E (IgE)-mediated allergic reactions requires binding of IgE antibody to its high-affinity receptor. Human basophilic KU812F cells express $Fc{\varepsilon}RI$ on the cell surface and act as effector cells in the allergic response. In this study, we investigated the effects of Scutellaria radix extract on the expression of the $Fc{\varepsilon}RI$ in human KU812F cells. Flow cytometric analysis showed that S. radix extract treatment caused a concentration-dependent decrease in $Fc{\varepsilon}RI$ expression on the cell surface. Furthermore, the level of $Fc{\varepsilon}RI$ ${\alpha}$, ${\beta}$, and ${\gamma}$ chain mRNA in KU812F cells was examined by RT-PCR. S. radix extract reduced total cellular $Fc{\varepsilon}RI$ $\alpha$ and ${\gamma}$ chain mRNA expression in a concentration-dependent manner. $Fc{\varepsilon}RI$-mediated histamine release was reduced from $21.75{\pm}1.34\;ng/10^6$ cells in non-treated cells to $16.46{\pm}1.98\;ng/10^6$ cells in S. radix extract treated cells. These results suggested that S. radix extract has the potential to down-regulate of FcRI expression and to inactivate basophils.
