The antihistaminic action of eighteen herbal medicines was investigated by the radioligand binding and functional assays. The hexane fractions of Trichosanthis radix, Mori cortex radicis and Evodiae fructus dosedependently inhibited [$^3$H] mepyramine binding to H$_1$, receptor in guinea-pig brain homogenates and histamine-induced contraction of isolated guinea-pig ileum. Antihistaminic action of the hexane and ethyl acetate fractions of Mori cortex radicis and the hexane fraction of Evodiae fructus was more potent than their antimuscarinic action evaluated from the inhibition of [$^3$H]QNB binding and carbachol response. The ethyl acetate and chloroform fractions from Scutellariae radix also inhibited histamine-induced contraction, but antihistaminic potencies of these fractions were almost identical with their antimuscarinic potencies. The hexane fractions of Mori cortex radicis and Evodiae fructus inhibited selectively the increase of histamine-induced cutaneous vascular Permeability in the rat dorsal skins. However, the ethyl acetate fraction from Scutellariae radix inhibited eqipotently the effects of histamine and serotonin on the vascular permeability. These results demonstrate that the hexane and ethyl acetate fractions of Mori cortex radicis and the hexane fraction of Evodiae fructus have the selective histamine H$_1$receptor blocking activity.

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).

Anti-allergic action of each water extracts of some crude drugs was investigated in mice and rats. The activity of hyaluronidase which was used in the screening test of anti-allergic action was inhibited significantly by Amomi Semen, Asiasari Radix, Cimicifugae Rhizoma, Cinnamomi Ramulus, Glycyrrhizae Radix and Scutellariae Radix. The 48-hour homologous passive cutaneous anaphylaxis(48-hr PCA) in mouse ear was inhibited significantly by intraperitoneal(i.p.) injection of Amomi Semen, Cimicifugae Rhizoma, and ketotifen, a comparative drug of an anti-allergic action. The increase of vascular permeability induced by histamine or serotonin was inhibited significantly by i.p. injection of Amomi Semen, Cimicifugae Rhizoma, Cinnamomi Ramulus and ketotifen. In rat dorsal skin, the increase of vascular permeability which was induced by histamine, serotonin or compound 48/80 was inhibited significantly by i.p. injection of Amomi Semen, Asiasari Radix, Cimicifugae Rhizoma, Scutellariae Radix and ketotifen. Armeniacae Semen and Liriopis Tuber which had not inhibited hyaluronidase activity did not inhibit 48-hr PCA and the increase of histamine, serotonin or compound 48/80-induced vascular permeability in mice and rats. These results suggest that each water extract of Amomi Semen and Cimicifugae Rhizoma has anti-allergic action.

To develop a wrapping film, which suppresses the microbial decay through the storage and prolongs the selflife of fruits and vegetables, the antimicrobial packaging films were prepared and applied to the preservation of strtwberries and cucumbers. Low density polyethylene(LDPE) film of 50㎛ thickness was faricated with 1% of Scutellariae baicalensis extract. The LDPE film impregnated with Scutellariae baicalensis extract showed antimicrobial activity on the disk test against Bacillus cereus, Escherchia coli and Fusarium sp.. The antimicrobial film changed the color and light transmittance, but did not affect heat shrinkage, mechanical tensile strength and wattability. Strawberries and cucumbers were separately wrapped with packaging films in the state of closely-adhered packaging as well as modified atmosphere packaging(MAP). The wrapped strawberries and cucumbers were stored for 21 days at 5$\^{C}$ and for 40 days at l0$\^{C}$, respectively. For the packaged strawberries and cucumbers at 5$\^{C}$ and 10$\^{C}$, the LDPE film impregnated with Scutellariae baicalensis extract showed the reduced growth of total aerobic bacteria, molds and yeasts and did not give any negative effect on other quality attributes during storage in comparison with conttrol film without any additive.

This study was carried out to screen herbs among herbal plants showing antimicrobial activity against some food spoilage and pathogenic microorganisms. One hundred fifteen kinds of herbal plants were extracted by 70% ethanol, and then they have been screened for antimicroorganisms. Six herbal plants such as Salviae radix, Dryopteris rhizoma, Terminaliae fructus, Araliae radix, Psoraleae fructus and Schisandrae fructus showed strong antimicrobial activities against Bacillus subtilis. Antimicrobial activities were showed in Anemarrhena radix and Dryopteris rhizoma on Candida albicans, and in Anemarrhenae radix, Dryopteris rhizoma and Polygalae radix on Schizosaccharomyces sp. It was revealed that eight herbal plants such as Dryopteris rhizoma, Salviae radix, Sappan ligunum, Sinomeniae radix, Schisandrae fructus, Rhui fructus, Sophorae radix and Inulae radix also showed antimicrobial activities on Streptococcus mutans. In addition, Anemarrhena radix, Curcuma tuber, Inulae radix, Polygonum radix, Sanguisorbae radix, Scutellariae radix and Terminaliae fructus and showed antimicrobial activities on Trichophyton mentagrophytes. Four kinds of herbal plants such as Dropteris rhizoma, Salviae radix, Terminaliae fructus and Scutellariae radix which showed broad antimicrobial spectrums were mixed by 1 : 1 ratio with the other herbal paints showing relatively strong microbial activities such as Terminaliae fructus, Sinomeniae radix and Scutellariae radix etc. The extracts of mixed herbal paints showed higher antimicrobial activities than those of single herbal plant.

Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Listeria. monocytogenes and Bacillus cereus are pathogenic bacteria that should not be detected in cosmetics and foodstuffs. Therefore, we first investigated the antimicrobial activities of extracts of Scutellariae Radix(SR), Coptidis Rhizoma (CR) and salicylic acid(SA) in these pathogenic microorganisms. Although SA has been known to exhibit anti-inflammation and antimicrobial activity against pathogenic microorganisms, a high concentration of SA may cause serious side effects such as skin redness, skin burning, peeling or tissue damage. Hence, we focused on diminishing side effects followed by treatment of a high concentration of SA and investigated whether the combinations of SA with various concentrations(25-400 mg/mL), SR and CR with a concentration(100 mg/mL) which did not show antimicrobial activity against E. coli and P. aeruginosa exhibited meaningful antimicrobial effect against both strains. In our results, the combinations of SA with the lowest concentration(25 mg/mL), SR(100 mg/mL) and CR(100 mg/mL) exhibited significant antimicrobial activity against E.coli in comparison to SA alone(25 mg/mL) showing no antimicrobial activity. Moreover, the combinations of SA (100 mg/mL), SR and CR showed seven times higher antimicrobial activity against E. coli than SA alone(100 mg/mL) and exhibited a significant antimicrobial activity in comparison to ampicilin (p<0.05). The combinations of SA(100 mg/mL), SR and CR showed two times higher antimicrobial activity against P. aeruginosa than SA alone. Therefore, these results indicated that the combinations of SR, CR and SA with low concentration expressed the synergistic antimicrobial effect against E. coli and P. aeruginosa and showed great potential as an antimicrobial agent.

Pruritus is a unpleasant symptom in the skin that provokes the act of or desire to scratch. Mast cells are important effector cells in allergic reactions such as pruritus and inflammation. The purpose of this study was undertaken to investigate the synergic anti-pruritic and anti-inflammatory effects of Scutellariae Radix (SB) plus Flos Loncerae (FL) extracts in rat peritoneal mast cells (RPMCs), pruritogen-induced scratching mice and 2,4-dinitrofluorobenzene (DNFB)-induced allergic mice. We investigated the effect of SB, FL and SB plus FL extracts on the production of tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-$1{\beta}$, and histamine in RPMCs, on the scratching behavior in ICR mice, and skin clinical serverity and inflammatory mediators in DNFB-induced allergic hairless mice. RPMCs stimulated with PMA plus A23187 or compound 48/80 significantly increased TNF-${\alpha}$, IL-$1{\beta}$ or histamine production compared with media control. However, TNF-${\alpha}$ IL-$1{\beta}$ or histamine levels increased by PMA plus A23187 or compound 48/80 treatment were significantly inhibited by SB, FL in a dose-dependent manner. Especially, SB plus FL pretreatment had a synergic inhibitory effects on stimulator-induced cytokines (TNF-${\alpha}$ and IL-$1{\beta}$) and histamine production. Moreover, SB plus FL administration had a synergic inhibitory effects on the scratching behavior induced by pruritogen (compound 48/80, histamine, serotonin, substance P) in ICR mice. Furthermore, SB plus FL administration had a synergic inhibitory effects on skin damage, inflammatory mediators, leukocyte and mast cell infiltration induced by DNFB in hairless mice. These results suggest that SB plus FL administration has a potential use as a medicinal plant for treatment against itching and inflammation-related skin disease.
