  • Allergic contact dermatitis (ACD) is a type IV delayed hypersensitivity reaction that results from exposures and subsequent sensitization to an environmental chemical. Crataegus Pinnatifida (CP) is commonly used to improve spleen function, remove retention of food, and promote blood circulation. This study is designed to investigate the effects of CP on ACD induced by 2,4-dinitrochlorobenzene (DNCB) in mice. In this experiment, the effects of CP on changes in body weights, ear and dorsum skin thicknesses, ear weights, clinical aspects on the dorsum skin, histopathological changes, spleen weights, cytokines were investigated. In addition, the effects on the proliferation rates of splenocytes were also investigated in vivo and vitro study. In results, CP spread (CPS) group and CP spread and administered (CPS+Adm) group showed decrease in spleen weights. In CPS+Adm group, dorsum skin thicknesses were decreased significantly compared to control group. CP treatment diminished erythema, desquamation and keratosis which were induced by repeated painting of DNCB. In histopathological observation, spongiosis and edema were diminished in CPS and CPS+Adm group. CP led to decrease in the proliferation rates of splenocytes in vivo and vitro. In conclusion, these data suggest that CP can decrease symptoms of ACD, so CP is useful to treat patient with ACD.

  • The purpose of this research was to investigate effects of Hyunsamchungpye-eum(HSCPE) on the anti-inflammatory/anti-allergic reaction in vivo and in vitro. HSCPE reduced the acute hind paw edema induced by histamine, the permeability of evans blue into peritoneal cavity. HSCPE inhibited the passive cutaneous anaphylaxis reaction in rat, the lethal anaphylaxis and degranulation of peritoneal mast cells induced by compound 48/80 in mice, HSCPE did not affect the Arthus reaction, but decreased the delayed type hypersensitivity induced by SRBC, contact dermititis induced by DNFB. These results suggest that HSCPE have an anti-inflammatory and anti-allergic action.

  • This study was undertaken to assess the effect of sound stress on humoral and cellular immune responses to thymus-dependent and independent antigens in mice. After mice were exposed to 4 hr daily sound stessors(83㏈) for 4 days before or after immunization, the primary and / or secondary immune response to sheep red blood cells(SRBC), polyvinylpyrroridone(PVP) or picry1 chloride(TNCB) were assayed. When mice were exposed to sound stressor before or after immunization, delayed-type hypersensitivity reaction and contact sensitivity to TNCB was remarkably depressed compared with those of the unstressed control mice. However, the primary and secondary hemagglutinin response of the stresed mice to SRBC showed a pronounced increase compared with that of the unstressed mice, In contrast to antibody response to SRBC, the primary antibody response of the stressed mic to PVP was almost not detected. surprisingly, the secondary antibody response to PVP of the mice receiving the secondary sound stress was markedly increased when the immune-depressed mice received the secondary immunization with PVP at 46 days after the primary immunization. The susceptibility of mice to intraven-oulsy infected Candida albicans was not changed by the sound stress.

  • The effects of Ephedrae herba on cellular and humoral immune responses were investigated in mice. Group A and B of mice received intraperitoneal injection of methanol extracts, ether fraction(E), petroleum ether fraction(PE), ethyl acetate fraction(EA) and water fraction(W) for 5 days or 10 days before sensitization. The other group received i.p. injection of ephedrine (Ep) or pseudoephedrine $({\psi}\;Ep)$ for 1 day prior to sensitization. The change of body and spleen weights showed a tendency of decreasing but that of thymus showed increasing. Ear swelling was maximum at 48 hours after challenge and was significantly decreased in the groups treated with EA, W, Ep, and ${\psi}\;Ep$. HA titer was enhanced in EA, W and EP treated groups, HE titer being significantly decreased.

  • The purpose of this research was to investigate effects of Bangpoongtongsungsan water extract(BTSE) on the immune reaction, anti-allergy action and anti-inflammatory action in BALB/c mice. The administration of BTSE (500mg/kg) enhanced the cell viability of thymocytes and the population of helper T cells in splenic T-lymphocytes. BTSE suppressed the production of nitric oxide, but enhanced the phagocytic activity in peritoneal macrophages. BTSE enhanced hemagglutination titer in mice. BTSE inhibited passive cutaneous anaphylaxis induced by egg albumin in rat, the lethal anaphylaxis induced by platelet activating factor and compound 48/80 in mice, and then inhibited the degranulation of peritoneal mast cells induced by compound 48/80. BTSE did not inhibit Arthus reaction, but inhibited the delayed type hypersensitivity induced by SRBC and contact dermatitis induced by DNFB. BTSE inhibited the acute hind paw edema induced by histamine after 30 minutes, the permeability of evans blue into peritoneal cavity induced by acetic acid and the writhing syndrome induced by acetic acid. These results suggest that BTSE has an immunopotentiative action, anti-allergy action and anti-inflammatory action via the inhibition of histamine release.

  • Wogonin (5,7-dihydroxy-8-methoxyflavone) is a down-regulator of cyclooxygenase-2 and inducible nitric oxide synthase expression, contributing to anti-inflammatory activity in vivo. For further characterization of modulatory activity on ploinflammatory gene expression in vivo, the effect of wogonin was examined in this experiment using animal models of skin inflammation. By topical application, wogonin inhibited an edematic response as well as ploinflammatory gene expression against contact dermatitis In mice. Wogonin inhibited ear edema ($19.4-22.6\%$) at doses of $50-200\;{\mu}g$/ear and down-regulated interleukin-$1{\beta}$ induction ($23.1\%$) at $200{\mu}g$/ear in phenol-induced simple irritation. Wogonin ($2{\times}50-2{\times}200{\mu}g$/ear) also inhibited edematic response ($51.2-43.9\%$) and down-regulated ploinflammatory gene expression of cyclooxygenase-2, interleukin-$1{\beta}$, interferon-$\gamma$, intercellular adhesion molecule-1 and inducible nitric oxide synthase with some different sensitivity against picryl chloride-induced delayed hypersensitivity reaction. All these results clearly demonstrate that wogonin is a down-regulator of ploinflammatory gene expression in animal models of skin inflammation. Therefore, wogonin may have potential for a new anti-inflammatory agent against skin inflammation.

  • To investigate the effects of carboxyethylgermanium sesquioxide (Ge-132) on the cyclophosphamide (CY)-induced immunotoxicity, hemagglutinin titer (HA-titer), splenic IgM plaque forming cells (PFC) and contact-delayed type hypersensitivity (CDTH) were assessed in mice. Ge-132 was orally administered alone (single dose of 300, 600, 900 mg/kg b.w.) or with CY (10 or 50 mg/kg, i.p.) to mice on the 2nd day before, simultaneously with, the 2nd day after immunization. Within Ge-132 alone-treated groups, HA-titer and PFC to SRBC were significantly and dose-dependently enhanced when compared with control group. HA-titer and PFC numbers suppressed by the treatment of CY alone were significantly restored by the concomitant treatment of CY and Ge-132. Also, Ge-132 significantly decreased DNFB-induced CDTH and inhibited the CY-enhanced CDTH. These results indicate that Ge-132 may be able to increase humoral immunity and inhibit the immunotoxicity by CY.

  • 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.
