  • Effects of the aqueous extract of Cimicifuga heracleifolia (CHAE) on the allergic reactions were investigated. CHAE inhibited systemic anaphylaxis induced by compound 48/ 80 in mice dose-dependently. Especially, CHAE inhibited compound 48/80-induced systemic anaphylaxis 100% with a dose of 0.5mg/g body weight. CHAE significantly inhibited serum histamine levels induced by compound 48/80. CHAE inhibited histamine release from the rat peritonea] mast cells activated by compound 48/80 or anti-DNP IgE. Our studies provide evidence that CHAE will be beneficial in the treatment of anaphylias.

  • Objectives: The root and stem of Sinomenium acutum has been used for treatment of arthritis and neuralgia in oriental medicine. To find new substances of the anti-anaphylactic drugs, we studied Sinomenium acutum. Methods: To investigate the effect of this plant, the effect on anaphylactic reaction, plasma histamine level, and tumor necrosis $factor-{\alpha}-(TNF-{\alpha})$ production were measured after the aqueous extract of Sinomenium acutum stem (SSAE) was administrated to mice and rats. Results: The SSAE (0.1 to 1000 mg/kg) dose-dependently inhibited systemic anaphylactic reaction induced by compound 48/80 in mice. Especially, SSAE reduced compound 48/80-induced anaphylactic reaction with 50% at the dose of 1000 mg/kg. SSAE (100 to 1000 mg/kg) also significantly inhibited local anaphylactic reaction activated by anti-dinitrophenyl (DNP) IgE. When mice were pretreated with SSAE at a concentration ranging from 0.1 to 1000 mg/kg, the plasma histamine levels were reduced in a dose-dependent manner. SSAE (1 to 1000 g/ml) dose-dependently inhibited histamine release from the rat peritoneal mast cells (RPMCs) activated by compound 48/80 or anti-DNP IgE. The level of cAMP in RPMCs, when SSAE was added, increased compared with that of a normal control. In addition, SSAE (0.1 g/ml) had a significant inhibitory effect on anti-DNP IgE-induced $TNF-{\alpha}$ production. Conclusions: These results indicate that SSAE inhibits mast cell-mediated anaphylactic reactions and $TNF-{\alpha}$ production from mast cells.

  • We studied the action of methyleugenol on immediate hypersensitivity. Methyleugenol completely inhibited systemic anaphylaxis induced by compound 48/80 in mice. Methyleugenol al so inhibited local anaphylaxis induced by anti-dinitrophenyl (DNP) IgE. Moreover, methyleugenol dose-dependently inhibited histamine release in peritoneal mast cells activated by compound 48/80 or anti-DNP IgE. These results suggest that the inhibitory effect of methyleugenol on anaphylaxis induced by compound 48/80 or anti-DNP IgE is due to, in part at least, the membrane stabilization of mast cells.

  • The present study was conducted to investigate the anti-allergic activity of HBT. We investigated the anti-allergic effects of HBT in RBL-2H3 basophilic leukemia cells by compound 48/80, a mast cell degranulator. HBT significantly inhibited ${\beta}$-hexosaminidase and histamine release from compound 48/80 stimulated RBL-2H3 cells. The in vitro anti-inflammatory activities of HBT in LPS-stimulated RAW 264.7 cells were investigated. HBT inhibited NO production in LPS-stimulated RAW 264.7 cells and effectively dowregulated the expression of iNOS mRNA and iNOS protein expression in LPS-stimulated RAW 264.7 cells. These result provide evidences that HBT may be beneficial in the treatment of allergic inflammtory disease.

  • 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.

  • Objectives : In this study, we investigated the effect of Saposhnikoviae Radix on allergic responses in ovalbumin(OVA)-induced Allergic rhinitis(AR) mice. Methods : BALB/c mice were orally administrated with Saposhnikoviae Radix water extract (SRW, 50 mg/kg) or anti-histamine drug, Ketotifen (10 mg/kg) as a reference drug, followed by sensitization and challenge of OVA. Mice were measured clinical symptoms and the serum levels of histamine, IgE, IL-4, and IFN-${\gamma}$, and observed histopathological changes of nasal mucosa H&E staining. Results : SRW significantly decreased rubs and the serum levels of histamine, IgE, and IL-4, and then increased the serum levels of IFN-${\gamma}$ in OVA-induced AR mice, and inhibited histopathological changes of nasal mucosa with inflammation and the eosinophils infilteration. Conclusions : These data suggest that SRW has anti-allergic effect through the inhibitory property of Saposhnikoviae Radix against allergic responses in allergic rhinitis.

  • The effect of aqueous extract of Sanguisorba officinalis L. (Rosaceae) root (SOAE) on the immediate-type allergic reactions by anal therapy was investigated. SOAE (0.01 to 1 g/kg) dose-dependently inhibited systemic anaphylaxis induced by compound 48/80 in mice. When SOAE was pretreated at the same concentrations with systemic anaphylaxis, the plasma histamine levels were reduced in a dose-dependent manner. SOAE (0.1 and 1 g/kg) also significantly inhibited local anaphylaxis activated by anti-DNP IgE. SOAE (0.001 to 1 mg/ml) dose-dependently inhibited the histamine release from rat peritoneal mast cells (RPMC) activated by compound 48/80 or anti-DNP IgE. The level of cyclic AMP (cAMP) in RPMC, when SOAE (1 mg/ml) was added, transiently and significantly increased compared with that of basal cells. These results provide evidence that anal therapy of SOAE may be beneficial in the treatment of allergic diseases.

  • Since the main symptoms of COVID-19 involve the respiratory system, the infection rate of this disease is predicted to be higher in patients with other respiratory conditions such as allergic rhinitis. In such a situation, it will be meaningful to conduct research on an allergy treatment that has fewer side effects and can effectively reduce allergy symptoms. Here, we prepared experimental samples under various fermentation conditions with mixed extracts of six medicinal plants. To examine the anti-allergic efficacy of these samples, an egg albumin-induced allergic rhinitis animal model experiment, a serum histamine and IgE experiment, and a COX and LO inhibitory activity experiment were conducted. As a result of animal experiments, OVA+SP-4 showed superior efficacy compared to OVA+SP-1 in nasal rubbing and sneezing experiments and had anti-allergic efficacy similar to that of OVA-cetirizine. The serum histamine concentration of OVA+SP-4 was also 1.3 times higher than that of the OVA+cetirizine group, showing a high histamine reduction ability, and IgE showed the same trend. An analysis of COX inhibitory efficacy also confirmed that COX-1 and COX-2 inhibitory efficacy is high, and the longer the fermentation time, the higher the antiallergic efficacy. The composition proposed by this study is expected to have a significant effect on sustainable allergy prevention and treatment in the future by applying it to human patients.

  • 알러지 반응이 일어나면 histamine이 방출되기 때문에 histamine을 정량 측정함으로써 유발된 알러지의 정도를 확인 할 수 있다. 일반적으로는 항원-항체반응으로 microplate reader를 이용하여 흡광도를 측정하여 정량 한다. 본 연구에서는 histamine 방출량을 측정함에 있어서 일반적인 항원-항체반응과 분석 화학적인 방법으로 HPLC-MS를 이용한 방법을 비교하였다. 세포주는 RBL-2H3를 사용하였고, C48/80으로 자극시켜 알러지를 유발하였다. 유발된 알러지는 ${\beta}$-hexosaminidase의 측정으로 탈 과립을 확인하였으며 실험의 정당성을 위하여 세포독성 능을 확인하였다. Histamine 정량에서 항원-항체반응에 의한 측정의 정량한계는 10.257 ppm이었고, HPLC-MS에 의한 정량한계는 0.020 ppm으로 현저한 차이를 보였다. 알러지 활성 및 항 알러지 실험에 있어서 histamine의 측정은 HPLC-MS를 이용한 분석이 더 정밀하고 정확한 실험인 것을 확인하였다.

  • Objectives : It has been recently shown that Piperis Longi Fructus (PLF) is involved in the reduction of eosinophil recruitment and production of Th2 cytokines in vivo. However, the main therapeutic mechanisms of PLF remains a matter of considerable debate. To investigate the therapeutic mechanisms of PLF, we examined the influence of PLF on regulatory T cells number, IgE, histamine production in vivo and Th1/Th2 cytokine balance in vitro. Methods : All mice were immunized on two different days (21 days and 7 days before inhalational exposure) by i.p. injections of 0.2 $m\ell$ alum-precipitated Ag containing 100 ${\mu}g$ of OVA bound to 4 mg of aluminum hydroxide in PBS. Seven days after the second sensitization, mice were exposed to aerosolized ovalbumin for 30 min/day on 3 days/week for 12 weeks(at a flow rate of 250 L/min, 2.5% ovalbumin in normal saline) and PLF (150 mg/kg) were orally administered 3 times a week for 8 weeks. Splenocytes from C57BL/6 mice at 8 weeks of age were stimulated with anti-CD3 (1 mg/ml) plus anti-CD28 (1 mg/ml) antibody for 48hrs. IL-4 and IFN-$\gamma$ in the culture supernatants were measured by ELISA Results : The suppressive effects of PLF on asthma model were demonstrated by the increase the number of regulatory T cells and by reducing IgE, histamine production in vivo and modulation of Th1/Th2 cytokine balance. Conclusions : These results indicate that PLF has a deep inhibitory effects on asthma model mice by increase the number of regulatory T cells, and by reducing IgE, histamine production.
