Gamhongro-ju is a Korean traditional alcoholic beverage made from medicinal herbs and spices. In this study, polyphenol content and antioxidant activities of gamhongro-ju and the 8 individual herb extracts used to make the beverage were determined. Cinnamon, saposhnikovia root, clove, ginger, violet-root cromwell, licorice, citrus peel and logan (2.5 g each) were extracted with 1000 mL of 45% and 60% purified ethanol (PE), and 45% traditionally distilled ethanol (TDE). The individual herb (20 g each) was extracted with 1000 mL of 60% PE. Polyphenol content, DPPH and ABTS radical scavenging activities of the extracts were measured. In the combined herb extracts, polyphenols were significantly higher in the 45% and 60% PE extracted for 90 days than those for 30 days. In the 8 individual herb extracts, the clove extract had the highest polyphenol content (2421~2446 mg/L). ABTS $IC_{50}$ values of the combined herb extracts were lower in the 60% PE and 45% TDE extracted for 90 days than those for 30 days. In the 8 individual herb extracts, the clove and cinnamon had the lowest ABTS and DPPH $IC_{50}$ values. In the individual extracts, ginger had the lowest polyphenol content; however, it was the third in the antioxidant activity.

Purpose : Hepatitis B virus DNA transfected cell line(HepG2.2.15) was cultured to evaluate the effect of herbs on the expression of HBeAg and the replication of HBV. HepG2.2.15 produces HBV particles as well as viral proteins into cell culture media. Methods : Extracts of herbs were adminitered to the cells on the proper concentration. Culture media was collected 48 hours after the herbal administration and HBeAg level in the media was examined by ELISA method. To confirm that the anti-viral effect was not due to direct cytotocixity of the extracts, normal cell proliferation was shown by cell counting. And as of the interference in protein synthesis of HepG2.2.15 by herb-extracts, we used the result of study that we performed before by ${\alpha}FP$ assay using EIA method. Results& Conclusion : Herb medicines like 地楡(Sanguisorbae Radix) and 覆盆子(Rubi Frusctus) showed significant inhibitory effect on HBeAg expression at p<0.01 and 五味子(Acanthopanacis Cortex) at p<0.05. Whereas, though some herbs such as ?草根(Rubiae Radix), 山査(Crataegii Fructus), 白芍藥(Paeoniae Radix Alba), and 大黃(Rhei Radix et Rhizoma) showed the tendecy to suppress HBeAg. most of them were not significant statistically. From the above, we could conclude that those herb medicines can be applied to patients effectively and further studies on effective fraction of some herbs are thought to be needed.

Six kinds of herbs(applemint, geranium, lemonbalm, rosemary, sage and thyme) were extracted with water and 95% methanol, and the electron donating ability, antibacterial activity and nitrite scavenging effect were examined. The electron donating ability of herbs ranged from 60.7 to 92.2% and the highest value was observed in geranium, followed by sage and lemonbalm. Antibacterial activity of methanol extracts was much stronger than that of water extracts and gram positive bacteria were more sensitive than gram negative bacteria. Rosemary and geranium exhibited excellent antimicrobial activities against a wide range of bacteria. Nitrite scavenging activity, which was measured at various pH conditions(1.2, 3.0, 3.6, 4.2), was the highest in all herbs at pH 1.2 and the lowest at pH 4.2, suggesting that it is pH dependent. Methanol fraction also provided higher nitrite scavenging effect than the water fraction.

The aim of this study was to evaluate if a composition of herb extracts, PLX-PLS was effective to treat atopic dermatitis (AD) in mice. SPZZC is a composition of herb extracts containing the roots of Scopolia parviflora and Paeonia lactiflora, the herb of Zizania caudiflora, the fruit of Ziziphus jujuba and the leaf of Chinese arborvitae. AD in BALB/c mouse was induced by patching ovoalbumin on the backside, while it in NC/Nga mouse was induced by repeated application of 1-chloro 2,4-dinitrobenzene (DNCB). Mice were topically treated with SPZZC or Domohorn ointment on the backside for 2 weeks (BALB/c) or 1 week (NC/Nga). Scratching behavior, clinical skin severity and the levels of WBC, neutrophil, eosinophil and total serum IgE were measured. After AD induction, scores of scratching behavior and clinical skin severity and the levels of WBC, neutrophil, eosinophil and total serum IgE were increased. Treatment with SPZZC significantly decreased scores of scratching behavior and clinical skin severity in a dose dependent manner in NC/Nga and BALB/c mice. Treatment with SPZZC 2% significantly decreased also the levels of WBC, neutrophil, eosinophil and total serum IgE. Especially, treatment of SPZZC 2% reduced more rapidly score of clinical skin severity than clobetasol cream. These results suggest that the SPZZC may be an alternative substance for the management of AD.

Various kinds of medicinal herbs and prescribed herb medicines which have usually been used for treatment of reducing fever, purging intense heat, and detoxication were secreened for antibacterial activity against Proteus vulgaris, S. aureus, and E. faecalis which causing puerperal infection. Minimal inhibitory concentrations of water and ethanol-soluble extracts of Hwangyon(C. japonica), Omae(P. mume), and Omiza(S. chinensis) were determined and using thin-layer chromatography the extracts of Hwangyon and Omiza were separated. The results obtained were as follow : 1. The water-soluble extracts of Keumeunhwa(L. japonica), Chiza(G. jasminoides), Hwangyon(C. japonica), Dansam(S. miltiorrhiza), Omae(P. mume) and Omiza(S. chinensis) showed antibacterial activities against P. vulgaris ; among them, the extracts of Hwangyon, Omae, and Omiza showed high antibacterial activities. The water-soluble extracts of Keumeunhwa(L. japonica), Hwangyon(C. japonica), Hwangkeum(S. baicalensis), Hwangbaek(P. amurense), Dansam(S. miltiorrhiza), Daehwang(R. coreanum), Omae(P. mume), Omiza(S. chinensis), Gingseng(P. ginseng), and Gamcho(G. uralensis) showed antibacterial activities against S. aureus : among them, the extracts of Hwangyon and Omiza showed high antibacterial activities. The water-soluble extracts of Banggi(C. trilobus), Daehwang(R. coreanum), Omae(P. mume), Omiza(S. chinensis), and Gamcho(G. uralensis) inhibited the cell growth of E. faecalis : among them, Omae and Omiza showed high antibacterial activities. The extract of Hwangyon(C. Japonica) and Omae(P. mume) showed no inhibition against E. coli. However, the extract of Omiza(S. chinensis) inhibited cell growth of both E. coli and B. subtilis. 2. The water- and ethanol-soluble extract of Hwangyon(C. Japonica) showed antibacterial activities against P. vulgaris and S. aureus, those of Omae(P. mume) against P. vulgaris and E. faecalis, and those of Omiza(S. chinensis) against all species tested, P. vulgaris, S. aureus, and E. faecalis. With the exception that ethanol-soluble extract of Hwangyon(C. japonica) showed much higher antibacterial activity against S. aureus than water-soluble one, antibacterial activities of both water-and ethanol-soluble ones were similar to each other of other two medicinal herbs. 3. When the prescribed herb medicines were tested, Sambohwan showed antibacterial activities against P. vulgaris and S. aureus. No prescribed herb medicine inhibitied the cell growth of E. faecalis. 4. Minimal inhibitory concentrations(MICs) of both water- and ethanol-soluble extracts of Hwangyon(C. japonica), Omae(P. mume), and Omiza(S. chinensis) against P. vulgaris were $2.5mg/m{\ell}$, $10mm{\ell}$, and $20mg/m{\ell}$, respectively. Those of both Hwangyon(C. japonica) and Omiza(S. chinensis) against S. aureus were $1.25mg/m{\ell}$ and $10mg/m{\ell}$, respectively. MICs of water-soluble extracts of Omae(P. mume) and Omiza(S. chinensis) against E. faecalis were $2.5m{\ell}$ and $5m{\ell}$, and those of ethanol-soluble extracts were $5m{\ell}$ and $10m{\ell}$, respectively Except for those of E. faecalis the cell growth of P. vulgaris and S. aureus were inhibited by much lower concentration of ethanol-soluble extracts used. As a result, the antibacterial compounds against P. vulgaris S. aureus, and E. aecalis are contained in the extracts of Hwangyon(C. japonica), Omae(P. mume), Omiza(S. chinensis), the prescribed herb medicine, Sambohwan, and might be used for treatment of puerperal infection. Further study should be carried out to identify which compounds affect the cell growth inhibition of P. vulgaris S. aureus, and E. faecalis.

Anti-enterovirus 71 (EV 71) activities of fifteen herb plant species extracts were examined by SRB assay, among which Origanum vulgare and Rosmarinus officinalis (Anna Rosemary) extracts exhibited the activities with $IC_{50}$ of 8.28 and $8.17\;{\mu}g/mL$, respectively. Their 50% cytotoxicity concentrations ($CC_{50}$) were 691.89 and $1104.19\;{\mu}g/mL$, and the therapeutic indices were 83.56 and 135.15, respectively. Amantadine (positive control) showed anti-EV 71 activity with 50% inhibitory concentration and $CC_{50}$ of 4.46 and $145.22\;{\mu}g/mL$, respectively. Addition of the methanol extracts of O. vulgare and R. officinalis (Anna Rosemary) in EV 71-infected Vero cells strongly inhibited the formation of visible cytopathic effects without changing the normal morphology of the cells. These results indicate that methanol extracts of O. vulgare and R. officinalis (Anna Rosemary) may contain antiviral compound inhibiting the EV 71 replication.

Ionophorous antibiotics have been used popularly for the protection of avian coccidiosis, though Halo-fuginone which is derived from an extract of the Dichroa febrifuga, was developed as an antimalarial and anticoccidial agent. The antibiotics are regarded as the causes of residues in the avian products, therefore the author has tried to find out more safe herbal materials for the control of avian coccidiosis. Thus, the extracts of 5 kinds of herbs, roots of Pulsatilla koreana Nakai and Sophora flavescens Aiton, nuts of Quisqualis indica Linne, whole herbs of Artemisia annua Linne and Polygonum aviculare Linne, were investigated on the efficacy against E tenella. Survival rates, bloody diarrhea, lesion scores, body-weight gains and feed conversion rate were investigated at the 1st and the 2nd week after infection. The bloody diarrhea in the groups treated with P koreana, A annua, Q indica and P aviculare were milder than those in the groups treated with S flavescens and infected control. The lesion score in the groups treat.4 with herb extracts(2.00$\pm$0.82~2.65$\pm$0.89) were lower than those in the control group (2.80$\pm$0.7l). But, there was not significant in all infected groups. The body weight gai in the groups treated with P koreana, S flavescens, A annua and Q indica(291.74$\pm$15.76~303.43$\pm$51.90) were higher than that in the control group (283.71$\pm$16.53) but there was not significant. In a conclusion, analyzing the data of the survival rates, bloody diarrheal symptoms, lesion scores, body weight gains and oocyst excretions, the extract of S flavescens, P koreana, A annua and Q indica were effective. The further research on the above herbal materials will have been carried out by the author and the other researchers by means of the chemical analysis of the components.

Herbal medicines are widely used in many countries for the treatment of many diseases. Although the use of herb extracts as alternative medicine is growing, their toxicological properties have not been thoroughly investigated. In this study, we have investigated the effects of water and ethanol extracts of 18 herbs on the hepatic lipid metabolism and steatogenic hepatotoxicity. Ethanol extracts of Cirsium japonicum, Carthamus tinctorius, Rehmanniae glutinosa (preparata), Polygala tenuifolia, Foeniculum vulgare, Polygonum multiflorum, and Acorus gramineus and water extracts of Polygonum multiflorum and Rehmanniae glutinosa induced lipid accumulation in Sk-hep1 human hepatoma cells as determined by Nile red staining. These extracts increased the luciferase activity of sterol regulatory element (SRE) and decreased that of peroxisome proliferator response element (PPRE), indicating the possibilities of enhanced fatty acid synthesis and decreased fatty acid oxidation. To identify the components responsible for the fat accumulation, we tested 50 chemicals isolated from the nine herbs. Apigenin, luteolin, pectolinarin and lupeol from Cirsium japonicum, 8-methoxypsoralen and umbelliferone from Foeniculum vulgare and pomonic acid and jiocerebroside from Rehmanniae glutinosa significantly increased the accumulation of lipid droplets. These results suggest that ethanol extracts of Cirsium japonicum, Carthamus tinctorius, Rehmanniae glutinosa (preparata), Polygala tenuifolia, Foeniculum vulgare, Polygonum multiflorum, and Acorus gramineus and water extracts of Polygonum multiflorum and Rehmanniae glutinosa can cause fatty liver disease by decreasing ${\beta}$-oxidation of fatty acid and increasing lipogenesis.

Protaetia Brevitarsis Seulensis(white grub) has been traditionally used as medicinal stuff to treat blood stasis, occlusion of menstruation, tetanus and liver cancer in Asian countries (Korea, Japan, China, Taiwan, India and Myanmar). Especially, Donguibogam, which is traditional korean medicinal book, described the white grub as traditional medicine to treat hepatic diseases and vascular disorders. The white grub has been considered as highly nutritional food. The major constituents of white grub are rich in protein, healthy fats, iron, calcium. Recent studies announced that white grub has hepatoprotective effect and anti-microbacterial effect. However, the immuno-enhancing effect of white grub extracts in RAW 264.7 macrophage cells has not been studied yet. In this study, the various concentrations of white grub extract were examined to find immuno-enhancing effects on RAW 264.7 cells. Cytotoxicity was determined by MTT assay and immuno-enhancing effect of white grub extract was investigated by measuring nitric oxide (NO) production compared with only lipopolysaccharide (LPS) treatment. White grub extracts (0.001 - 10 mg/ml) did not show cytotoxicity. Additionally, white grub extracts (0.001 - 1mg/ml) had Immuno-enhancing effect on RAW 264.7 cells compared with only LPS treated group. These results might be provided proof to develop beneficial immuno-enhancing material for human health.
