Objectives : This study was conducted to determine if Scutellaria baicalensis can be used in cosmetic emulsion cream for patients with atopic dermatitis. Methods : Scutellaria baicalensis extract was obtained with the use of butylene glycol through the pressurized solvent extraction(PSE). The antioxidative activity was assessed through SOD-like activity measurement and skin irritating potential was tested using human patch test. Antimicrobial activity was measured by the clear zone formed against Staphylococcus aureus and Escherichia coli and the rheological effects on the emulsion creams were examined using oscillation test. Results : The SOD-like activity increased dose-dependently and was about 90% at 1,000ppm of Scutellaria baicalesis extract. And Scutellaria baicalensis extract did not show any potential to be irritating to the human skin, but it could not be used as an antimicrobial agent for its poor antimicrobial activity against Staphylococcus aureus. The complex modulus decreased by 1,000 pascals and the loss angle also decreased by 20% with the addition of Scutellaria baicalensis extract into the cosmetic emulsion creams, that is, the extract can confer more elastic property on the vehicle. Conclusion : From those results, Scutellaria baicalensis extract can be effectively used as an antioxidant and reinforces the elastic skincare film formed by the application of cream for patients with atopic dermatitis.

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.

Gastritis and gastric ulcer were known to be induced by gastic acid, stress, ethanol, Helicobacter pylori and free radical, etc. This study was performed for the development of a new drug or nutraceutical from medicinal plants or natural products with anti-gastritis, anti-ulcerative and gastroprotective activities. The water extract of Scutellaria baicalensis was exhibited potent inhibition in HCl ethanol-induced gastric lesion, acetic acid-induced and Shay ulcers, indicating the effects on gastric lesion and ulcer in rats. The water extract of Scutellaria baicalensis significantly inhibited HCl ethanol-induced gastric lesions at the oral dose of 300, 500 mg/kg. In pylorus ligated rats, the treatments of the water extract from Scutellaria baicalensis showed decrease in the volume of gastric secretion and acid output and increase pH at oral dose of 300, 500 mg/kg. And significantly reduced acetic acid-induced ulcer at the oral dose of 500 mg/kg for 12 days. In this study, we have found that the water extract from Scutellaria baicalensis had significant improvement in acute gastritis and ulcer at the dose of 300, 500 mg/kg and in chronic gastritis and ulcer at the dose of 500 mg/kg. Also we evaluated the antibacterial activity against Helicobacter pylori treated with Scutellaria baicalensis. Scutellaria baicalensis had a equivalent antibacterial activity with ampicilin against H. pylori at the dose of $100\;{\mu}/ml$. In histological examination, the water extract of Scutellaria baicalensis drastically restored gastric damages induced by HCl ethanol solution, pylorus- ligature and acetic acid. Therefore, we may use the water extract from Scutellaria baicalensis as antigastritic and antiulcerative agent for the purpose of the improvement or treatment of gastritis and gastric ulcer.
