Lonicerae Flos containing formulation, Geumeumyoungji-tang (GYT), is an herbal prescription prepared using 5 different herbal drugs, namely, Lonicerae Flos, Ganoderma, Lactucae Herba, Xanthii Fructus, and Smilacis Rhizoma. This study was focused on the investigation of the pharmacological effects of GYT on allergic reactions. As the first step of the study, GYT was administered BALB/c mice which were sensitized by 2,4-dinitrofluorobenzene (DNFB). As the result GYT ameliorated dermatitis provoked by DNFB. The serum IgE level of the DNFB sensitized-mouse was significantly decreased when GYT was administered. In order to confirm the moderating effect of this prescription on allergic reaction, GYT was pretreated to human mast cells (HMC-1) before they were stimulated by phorbol-12-myristate 13-acetate plus calcium ionophore A23187 (PMACI). GYT suppressed secretion of inflammatory cytokines, interleukin (IL)-6 and IL-8, from HMC-1. Additionally, pretreatment of GYT showed regulating effect on COX-2 expression. Collectively, these findings provide insights into the pharmacological actions of GYT as a potential agent for treatment of allergic dermatitis.

Hataedock is a Korean medical treatment that administers herbal extracts orally to newborn infants. This method is used for alleviating harmful heat and excreting fetal wastes by meconium. The purpose of this study was to evaluate anti-inflammatory effect of Hataedock method with Douchi on 2,4-dinitrofluorobenzene (DNFB)-induced atopic dermatitis (AD). The 3-week-old NC/Nga mice were divided into 3 groups: the control group (Ctrl), the AD-induced group (AE), and the Hataedock-treated group (GT). Only the GT group was treated with Hataedock at the 3rd week. After 28 days from Hataedock treatment, we induced AD-like dermatitis to the AE and GT group by DNFB. The effects of Hataedock were evaluated by immunohistochemical method. In the epithelium, PKC-positive reaction of the GT group was decreased by 57%. In the dermal papillae, IL-4-positive reaction was decreased by 34%. In the dermis, the distribution of degranulated mast cells was decreased and substance P-positive reaction was decreased by 49%. In the skin tissue, edema was decreased and MMP-9-positive reaction was decreased by 71%. Tissue damage such as epithelial cell hyperplasia, infiltration of granulocyte and lymphocyte, and capillary distribution were also decreased. The Hataedock method with Douchi maintained skin barrier and inhibited skin-damaging factors via regulating Th2 differentiation. In conclusion, Hataedock has a potential for preventative treatment of AD. Further studies are necessary to investigate the immune-regulating mechanism and verify the safety and efficacy of the Hataedock method.

Scutellaria baicalensis Georgi is one of major herbs used to treat patients with skin diseases diagnosed by wind-heat syndrome. This study was designed to investigate the effects of Scutellaria baicalensis Extract (SBE) on skin lesion of Contact dermatitis (CD) in mice. We investigated the effects of SBE on skin thickness, skin lesions, erythema index and melanin index in vivo. The effects on body weights and spleen/body weight ratio were also investigated in mice with CD induced by topical application of 1-Fluoro-2,4-dinitrofluorobenzene (DNFB). In our results, topical application of SBE lowered skin thickness significantly. In addition, SBE ameliorated skin lesions such as erythema, exudate and petechia in mice with CD. SBE also inhibited erythema index elevated by DNFB significantly. finally, SBE did not affect body weight and spleen/body weight ratio. In conclusion, these data imply that SBE can ameliorate skin lesion of CD such as erythema, exudate and petechia, and be used to treat CD patients with relative safety.

The present experiment was designed to investigate the effects of behavioral, response to immune function in response to electric footshock in mice. Mice were subjected to electric footshock for 3 days(two sessions a day, 11 times of shock for about 31 minutes a session). The humoral immune response was measured using mice immunized with rat RBC. The cell-mediated immune responses were evaluated by contact hypersensitivity to 2, 4-dinitrofluorobenzene(DNFB) and by phytohemagglutin(PHA)-stimulated splenocytes proliferation assay. In stressed group, electric footshock suppressed significantly anti-rat RBC antibody production(p<0.05), but enhanced significantly $T_{48}$ relative to $T_{24}$ in contact hypersenstivry (P<.01) and T-cell proliferation response(P<.05) by PHA stimulation elative to control group. T-cell proliferation response by PHA stimulation was significantly correlated to the movement than the sensitivity and coping behavior in the mouse, in response to the electric footshock. These data supper the importance of behavioral response in stress-induced changes of immune functions.

Objectives : The water extract of Hwangnyeonhaedok-tang (HHT), composed of the Scutellariae Radix, Coptidis Rhizoma, Phellodendri Cortex and Gardeniae Fructus has been traditionally used to treat fever, inflammation, gastritis and hypertension in east asia. However, little is known about the ameliorative effects of HHT on atopic dermatitis. Therefore, the purpose of this study was to investigate the therapeutic effect of HHT on atopic dermatitis Methods : We investigated the inhibitory effects of HHT on the production of proinflammatory cytokines in rat peritoneal mast cells (RPMCs), on the scratching behavior in ICR mice, and on atopic dermatitis symptoms in 2,4-dinitrofluorobenzene (DNFB)-induced atopic dermatitis-like model hairless mice. Results : Levels of TNF-${\alpha}$ and IL-$1{\beta}$ increased by PMA plus A23187 co-treatment were significantly inhibited by HHT in a dose-dependent manner. HHT also inhibited the histamine release from RPMCs stimulated by compound 48/80, which promotes histamine release. The oral administration of HHT reduced the scratching behavior induced by compound 48/80 and histamine in ICR mice. Furthermore, the intradermal treatment of HHT reduced the ear edema, skin lesions, and atopic molecular marker (IgE and IL-4) in DNFB-induced atopic dermatitis model mice. Conclusions : These results suggest that HHT may be used as a potential treatment for AD as a prescription for treatment of atopic dermatitis.

This study were done to know the effects of Dangkiyeumja on the in vivo and in vitro immune responses of mice. The recipes of Dangkiyeumja used in this study enhanced such, cellular functions of immunocytes as phagocytic capacity of macrophages, rossett-eforming abilities of splenocytes and metabolic activities of lymphocytes, However, the same recipes decreased the formation of such reactive oxygen intermediates(ROI) as superoxide and hydrogenperoxide from the macrophages. The effects of the same recipes on the in vim immune responses was suppressive on the cellular immune response(CIR)measured by delayed-type hypersensitivity against dinitrofluorobenzene and mildly enhancing for the humoral immune response measured by antibody production against sheep red blood cells. The results of this study could be summarized as follow: 1. Administration of Dangkiyeumja enhanced the phagocytic activity of the murine macrophage. 2. Administration of Dangkiyeumja decreased the formation of ROI in the murine macrophage 3. Administration of Dangkiyeumja increased the number of the splenic rotte forming cells in the mouse. 4. Administration of DangKiyeumja did not effect the antibody production against sheep red blood cells. 5. Administration of Dangkiyeumja depressed the delayed-type hypersenitivity against dinitrofluoro benzene in the mouse. The result of this study suggest that Dangkiyeumja could ameliorate the hypersensitivity reactions by reducing the formation of ROI and decreasing the CIR without affecting the other functions of immunocytes.

This study was undertaken to test the effects of Daturae Flos(DF) and Daturae Semen(DS) on the cellular and humoral immune responses, and the functions of the cells involved in immunoinflammation. Both extracts decreased the activity of superoxide dismutase, and the decrease was greater in the mouse group which was treated with DS. Both extracts decreased the phagocytic activity as measured by assessing the number of the latex particle within the phagocyte after incubation of peritoneal macrophages with fluorochrome-labelled latex particle and decreased natural killer cell activity as measured by enumerating the viable YAC-1 cells after treatment of target cells with splenic natural killer cells. Both extracts also decreased the cell-mediated immunity in vivo as assessed by measuring the ear thickness after sensitization and challenge with dinitrofluorobenzene, however, had no effects on the humoral immune responses as measured by checking hemolysin and hemagglutinin titers after immunization with sheep red blood cells(SRBC). Extracts of Semen caused decrease in the number of rosette forming cells between the splenic cells and SRBC. The results of this study suggested that both Daturae extracts could depress the immunoinflammation by affecting the various cell types involved in inflammation.

The purpose of this research was to investigate the effects of Bopaewon-tang (BT) on allergic reaction. In the present study, we examined the effect of BT on type 1 and type tV allergic reaction. BT (500 mg/kg) did not affect the systemic anaphylaxis induced by compound 48180 and the passive cutaneous anaphylaxis induced by anti-dinitrophenyl (DNP)-IgE and DNP-human serum albumin in vivo. Also, BT did not affect the release of histamine from peritoneal mast cells in rats. In addition, BT did not affect the permeability of evans blue into peritoneal cavity, but inhibited the writhing syndrome induced by acetic acid. BT inhibited the delayed type hypersensitivity induced by SRBC and the contact dermatitis induced by dinitrofluorobenzene. These results indicate that BT may be useful for the prevention and treatment of type IV allergy related disease.

To evaluate whether chaff vinegar liquor (CVL) has potential in ameliorating allergic symptoms in mice, we tested the anti-allergic activities with a DNFB (dinitrofluorobenzene)-induced allergic mouse model. The DNFB-induced allergic symptoms were reduced by 20% compared to the control by chaff vinegar liquor supplemented with Perilla frutescens var. acuta. Allergic symptoms were examined by measuring the width of epidermis swelling. The hematoxyline & eosin (H&E) staining also revealed that the chaff vinegar liquor dramatically decreased the allergic symptoms in the epidermis of the ear. These results collectively suggest that the chaff vinegar liquor supplemented with P. frutescens var. acuta has potential in ameliorating allergic symptoms, showing that the liquor could be a useful biomaterial(s) for the nutraceutical or cosmetic industries.

Cordyceps bassiana is one of Cordyceps species with anti-oxidative, anti-cancer, anti-inflammatory, anti-diabetic, anti-obesity, anti-angiogenic, and anti-nociceptive activities. This mushroom has recently demonstrated to have an ability to reduce 2,4-dinitrofluorobenzene-induced atopic dermatitis symptoms in NC/Nga mice. In this study, we further examined phytochemical properties of this mushroom by column chromatography and HPLC analysis. By chromatographic separation and spectroscopic analysis, 8 compounds, such as 1,9-dimethylguanine (1), adenosine (2), uridine (3), nicotinamide (4), 3-methyluracil (5), 1,7-dimethylxanthine (6), nudifloric acid (7), and mannitol (8) were identified from 6 different fractions and 4 more subfractions. Through evaluation of their anti-inflammatory activities using reporter gene assay and mRNA analysis, compound 1 was found to block luciferase activity induced by $NF-{\kappa}B$ and AP-1, suppress the mRNA levels of cyclooxygenase (COX)-2 and tumor necrosis factor $(TNF)-{\alpha}$. Therefore, our data strongly suggests that compound 1 acts as one of major principles in Cordyceps bassiana with anti-inflammatory and anti-atopic dermatitis activities.
