The purpose of this research was to investigate the effect of Kamidangkwieumja(KDEJ) water extract on the allergy reaction in mice. The results were obtained as follows: 1. The passive cutaneous anaphylaxis induced by egg albumin in fat was not affected. 2. The lethal anaphylaxis induced by platelet activating factor in mice. was inhibited. 3. The degranulation of peritoneal mast cells induced by compound 48/80 was not affected. 4. The acute hind paw edema was inhibited after 2hours later when it was induced by histamine. 5. The permeability of evans blue into peritoneal cavity induced by acetic acid was not affected. 6. Arthus reaction in mice was not affected. 7. The delayed type hypersensitivity induced by SRBC was inhibited. 8. The contact dermatitis induced by DNFB was not affected. 9. The hemagglutination titer induced by SRBC was inhibited. 10. The writhing syndrome induced by acetic acid was inhibited. 11. The population of heper T cells in mice thymus was enhanced. 12. The phagocytic activity of peritoneal macrophages was enhanced. 13. The production of nitric oxide from peritoneal macrophages was not affected. These results suggest that the anti-allergy effect of KDEJ is caused by steroidlike and enhanced immune action. The steroidlike action of KDEJ correspond with steroid-applying-method that frequently used in clinic, so it is used io treatment of psoriasis. The research on anti-allergy of KDEJ might has to be continued.

Allergic diseases are the result of Th2-dominated responses to single or multiple environmental allergens. Th2 cytokines regulate these mechanisms of allergic disease at many levels, including initiation, progression, and persistence. The effect of hwangryun-Hae-Dok-Tang (HRHDT) on tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) and interleukin-4 (IL-4) stimulated inflammation was investigated using 3-(4,5-dimethylthiazol-2-yl)-2,5- diphenyltetrazolium bromide assay, thymus and activation-regulated chemokine (TARC), eotaxin, regulated on activation normal T cells expressed and secreted (RANTES) immunoassay on the human bronchial epithelial microglial cells. From the present study, the crude extract of Hwangryun-Hae-Dok-tang suppressed the TNF-${\alpha}$ and IL-4 stimulated TARC, eotaxin, and RANTES production in the human bronchial epithelial A549 cells. Based on the present results, Hwangryun-Hae-Dok-tang may be useful in the treatment asthmatic allergy by inhibiting TARC, eotaxin, and RANTES chemokines.

The present work evaluated the effects of alcoholic extracts of salvia (Salvia officinalis), thyme (Thymus vulgaris), and 2 pure compounds (thymol and menthol) on the viability of Echinococcus granulosus protoscolices in vitro. Four different concentrations of each extract (2,500, 1,500, 1,000, and 500 ${\mu}g$/ml) and 3 different concentrations each of thymol and menthol (50, 10, and 1 ${\mu}g$/ml) were used. Concentration of 2500 ${\mu}g$/ml of both extracts showed a significant protoscolicidal activity on the 6th day. Complete loss of viability of protoscolices occurred with 500 ${\mu}g$/ml concentration of both extracts at day 6 and day 7 post-treatment (PT), respectively. Pure compounds, i.e., menthol and thymol, showed potent effects with 50 ${\mu}g$/ml concentration at day 2 and day 5 PT, respectively. These effects were compared with those of albendazole sulfoxide (800 ${\mu}g$/ml), a commonly used treatment drug for hydatidosis. Krebs-Ringer solution and the hydatid cystic fluid at a ratio of 4:1 was a good preservative solution which kept the protoscolices viable for 15 days.

We have investigated the immunomodulatory activity of water extracts of Acanthopanax divaricatus var. alveofructus in male ICR mice. Mice were administrated with fermented milk containing freeze-dried extract 3 mg/Kg (A), 9 mg/kg (B), 27 mg/Kg (C) per body weight with A. divaricatus var. alveofructus (loots : leaves : stem) : Codonopsis lanceolata = (5 : 2 : 1.5) : 1.5 for 7 and 10 weeks, respectively. Body weight, relative organ weight, cellularity of lymphoid organs, plaque- forming cell (PFC) assay, agglutination (AGG) test and lymphoproliferation were examined in various groups of animals. Any significant differences of body weight gain were not recorded in the tested ICR mice. There was significant different (p<0.05) in the spleen index in B group of 10 weeks and C group of 7 weeks fed mouse. The thymus gain weight was increased during administration of the extract, but there was no significant increase on other organs gain. Humoral immunity as measured by PFC showed more decreased PFC level in 10 weeks than in 7 weeks. In the HT, A. divaricatus var. albeofructus extract also showed a significant increase (p<0.05) in C group of 10 weeks. Administration of extracts from A. divaricatus var. albeofructus increased significantly in the production of IgG antibodies on the mice immunized with SRBC in B group of 7 and 10 weeks (p<0.05).

In this study, the radioprotective effects of Grifola umbellata hot water extracts (Gu-extract) on mice were investigated. Single pre-administration of Gu-extract increased the 40-day survival ratio of irradiated mice from 65.5％ to 78.6％. The growth of 3 week old male mice in the irradiated group was slightly retarded as compared to those of the control and Gu-extract treated mice. The average spleen and thymus weights of the irradiated mice were lower than those of the control and Gu-extract treated mice. The weight reduction of testis in the irradiated mice was significant. While it was relatively slight in the Gu-extract treated mice as compared to that of control mice. No significant difference in the weight was observed in heart, kidney or liver among three groups. The leukocytes of the Gu-extract treated mice did not decrease dramatically as in the irradiated group, but recovery patterns were similar in both groups. Reduction of erythrocytes were similar in both groups but its recovery occurred more rapidly in the extract treated group. The glucose level of the Gu-extract treated group did not change during the period examined, while it was still higher in the irradiated group than the level in the control group in two weeks. The cholesterol levels in the irradiated and the Gu-extract treated groups were higher than that of control group on day 7, but decreased to the level of the control group on day 14. No difference was observed in total protein amount of the serum among the three groups. SDS-polyacrylamide gel electrophoresis of the soluble proteins extracted from various organs did not reveal differences to any extent in all groups except in the livers of the irradiated and extract treated groups, in which some proteins were missing or less present.

Although BinSo-San(BSS), a mixed herbal formula consisted of 11 types of medicinal herbs and have been used as anti-inflammatory agent, In the present study, the acute toxicity (single oral dose toxicity) of lyophilized BSS aqueous extracts was monitored in male and female mice after oral administration according to Korea Food and Drug Administration (KFDA) Guidelines (2005-60, 2005). In order to observe the 50% lethal dose ($LD_{50}$), approximate lethal dosage (ALD), maximum tolerance dosage (MTD) and target organs, test articles were once orally administered to female and male ICR mice at dose levels of 2000, 1000, 500, 250 and 0 (control) mg/kg (body wt.) according to the recommendation of KFDA Guidelines (2005-60, 2005). The mortality and changes on body weight, clinical signs and gross observation were monitored during 14 days after dosing according to KFDA Guidelines (2005-60, 2005) with organ weight and histopathology of 12 types of principle organs. We could not find any mortality, clinical signs and changes in the body weights except for dose-independent increases of body weight and gains restricted in 1000 mg/kg of BSS extracts-dosing female group. Hypertrophic changes of lymphoid organs.thymus, spleen and popliteal lymph nodes were detectedat postmortem observation with BSS extracts dose-dependent increases of lymphoid organ weights, and hyperplasia of lymphoid cells in these all three lymphoid organs at histopathological observations. These changes are considered as results of pharmacological effects of BSS extracts or their components, immunomodulating effects, not toxicological signs. In addition, some sporadic accidental findings such as congestion spots, cyst formation in kidney, atrophy of thymus and spleen with depletion of lymphoid cells, and edematous changes of uterus with desquamation of uterus mucosa as estrus cycles were detected throughout the whole experimental groups including both male and female vehicle controls. The significant (p<0.01) increases of absolute weights of kidney and pancreas detected in BSS extracts 1000 mg/kg-treated female group are considered as secondary changes from increases of body weights. The results obtained in this study suggest that the BSS extract is non-toxic in mice and is therefore likely to be safe for clinical use. The LD50 and ALD of BSS aqueous extracts in both female and male mice were considered as over 2000 mg/kg because no mortalities were detected upto 2000 mg/kg that was the highest dose recommended by KFDA and OECD. In addition, the MTD of BSS extracts was also considered as over 2000 mg/kg because no BSS extracts-treatment related toxicological signs were detected at histopathological observation except for BSS or their component-related pharmacological effects, the immunomodulating effects detected in the present study.

Total polyphenol contents, flavonoid contents, 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging activities of ethanol extracts of 20 herbal plants (sage, turmeric, mace, bayleaf, fenugreek, oregano, blackpepper, whitepepper, clove, marjoram, cinnamon, coriander, basil, dillseed, mustard, cadamon, thyme, celery, rosemary, cumin) were analyzed for the screening of high flavonoid-containing plant resource. Thyme extract, showing the highest flavonoid content and a high degree of antioxidant activity, was selected as a bioactive cosmetic material. The total polyphenols and flavonoids contents of thyme extracts were measured as 6.90 mg chlorogenic acid equivalent (CAE)/100 g and 1.71 mg naringin equivalent (NE)/100 g, respectively, and DPPH radical scavenging activities was 90%. Among the tested organic solvents, hexane gave the highest extraction yield. Thus hexane was selected as the most suitable solvent for the extraction of thyme. Response surface method was used to obtain optimized extraction conditions for thyme: reaction temperature of 35.9 ℃, raw material to hexane ratio of 1.63:25 (w/v), and reaction time of 192 min. These predicted extraction conditions was validated by a total flavonoid extraction experiment showing a value equivalent to 96.3% of the predicted total flavonoid content. It is expected that the optimized solvent extraction conditions could be used for the production of flavonoid using thyme.

Housefly (Musca domestica L.) maggots are used as biomedical material. Ethanolic extracts of fly maggot (EM) were orally administered to male rats at levels of 0 (control group), 4.0, 6.0, and 8.0 mg per 100 g live weight for 40 days. Serum triglycerides, total cholesterol, and LDL-C decreased by 17.90, 17.60, and 16.37%, respectively, whereas HDL-C increased by 20.48% in the EM group compared with these parameters in a control group (p<0.05). Thymus and spleen weights dose-dependently increased by 21.42% and 21.42%, respectively, but abdominal fat decreased by 39.66% after EM administration compared with that in the control group (p<0.05). IgG, IgA, and IgM increased 35.14, 68.65, and 190.16%, respectively, in the EM groups compared to the control group (p<0.05). Bifidobacterium and Lactobacillus increased by 41.68% and 35.55%, respectively, in the EM groups compared with the control group, and Bacteroides, Clostridium, Escherichia, and Streptococcus decreased by 24.96, 46.37, 25.00, and 34.05%, respectively, in the EM groups compared with the control group (p<0.05). Compared with the control group, total organic acids, acetic acid, and propionic acid increased by 31.11, 49.34, and 24.88%, whereas butyric acid, isobutyric acid, valeric acid, and isovaleric acid decreased by 30.79, 72.64, 32.90, and 63.16% respectively, in the EM groups (p<0.05). These results suggest that EM has a bifidogenic effect on immune cell development, blood lipid levels, and abdominal fat reduction by increasing the production of organic acid and numbers of cecal microorganisms in animals.

Pneumonia is infection of air sacs in lungs by bacteria, viruses, fungi and abnormal atmosphere condition. That causes to inflammation and fills up with pus and fulid in air sacs. The symptoms of pneumonia are heavy cough, fever, shortness and rapid respiration and sputum with blood. Also, that remains sequela after the recovery. Thymus quinquecostatus (TQ) has a strong antibacterial effect. That has been used a natural medicine for bronchitis, asthma and nervous inflammation. In this study evaluated anti-inflammatory effects of TQ on IFN (interferon)-γ/TNF (tumor necrosis factor)-α (20 ng/ml) stimulation. MRC-5 cells were seeded at 1 × 10⁵ cells/well in a 24-well plate and stabilized overnight at 37℃. The cells were treated with various concentrations of TQ extracts (DW, 30, 50, 70, 95% EtOH, 0.1~100 mg/ml) for 4h, Subsequently IFN-γ/TNF-α (20 ng/ml) was added to each well and incubated over 12h. the production of inflammatory cytokines were measured by Enzyme-linked immunosorbentassay(ELISA) method. The absorbance was measured at 450 nm using microplate reader. The treatment with TQ extract at dose of 0.1 to 100 mg/ml did not show cytotoxicity in MRC-5 cells (showed cytotoxicity at 95% EtOH 100 mg/ml). The results demonstrated that stimulation of TNF-α/IFN-γ significantly increased the production of inflammatory mediators in the MRC-5 cells compared with unstimulated cells. By contrast, treatment with TQ extreats doses of 0.001 to 10 mM significantly suppressed the production of IL-6 and IL-8. Especially. The higher percent of ethyl alcohol extracts suppressed the production of inflammatory cytokines. This results are considered that essential oil of TQ is extracted according to ethyl alcohol percent. Therefore, TQ has potential to mitigate pulmonary disease that can be used a medicine for pneumonia
