  • The effect of aqueous extract of Salvia plebeia R. Br. (Labiatae) (AESP) on immunoglobulin (lgE) antibody mediated allergic reactions in rats was investigated. AESP inhibited passive cutaneous anaphylaxis (PCA) when intravenously, intraperitoneally, and orally administered. AESP dose-dependently inhibited histamine release from rat peritoneal mast cells activated by anti-DNP IgE antibody. Moreover, AESP had an inhibitory effect on anti-DNP IgE antibody induced $TNF-{\alpha}$ production from RPMC. These results suggest that AESP inhibit the IgE-mediated allergic reaction in rats.

  • Spirometra erinacei의 유충인 sparganum(metacercoid)에 감염되었을 때 호산성백혈구의 증가와 IgE 항체역가가 증가된다는 보고가 있다. 이 기생충에 감염되었을 때 IgG 항체와 IgE 항체를 유도하는 충체의 항원성분의 소재를 면역세포조직화학적 방법으로 충체의 성체와 유충에서 비교하였고, 또한 충체의 추출물을 SDS-PSGE와 EITB를 이용하여 IgG와 IgE 항체 유도 항원성분의 면역적 특성도 추구하였다. IgG와 IgE 항체 유도성분은 성체와 유충의 근층에서 공통적으로 분포되어 있었고, IgG 항원성분은 근층 뿐만 아니라 외피층과 유조직층에서도 반응이 나타났으며, 성체의 수태편절에서는 자궁 내에 있는 충난의 표면에서도 반응이 나타났다. 충체의 외피층에서 항원성분을 면역황금 표지법으로 관찰한 결과, 충체의 외피층(tegument)에서 IgG 항원성분의 분포밀도가 IgE 항원성분의 밀도보다 컸다. 충체의 추출물 중 IgG, IgE 유도 항원성 단백질의 면역학적 특성을 비교하였다. 성체의 추출물의 43개 분회 중 21개 분획이 IgG 항원성분으로서 반응하였고, IgE 항원성분으로는 21개 분획에서 반응하였다. 이들 중 11개 분획 (410, 304, 268, 174, 162, 116, 92, 86, 72, 60, and 59 kDa)에서 IgG와 IgE가 교차반응하였으며, 유충의 추출물의 36개 분획 중 IgG 항원성분으로 22개의 분획에서 반응이 나타났고, IgE 항원성분으로는 13개의 분획에서 반응하였으며, 이들 중 5개 분획(204, 116, 92, 79, and 59 kDa)에서 IgG와 IgE가 서로 교차반응하였다.

  • Objectives : Socheongryong-Tang(小靑龍湯, SCRT), a herbal remedy, has been widely used to treat respiratory disease such as cough and asthma in Oriental countries. Recent years SCRT was known as anti-allergic agent. However, its therapeutic mechanisms including immunoglobuline such as IgE, IgG1, IgG2a productions are unclear. Methods : We investigated the effects of SCRT on levels of antigen specific total antibody, IgE, IgG1, IgG2a using ELISA method in serum from allergen-induced asthma mice. Results : SCRT decreased level of antigen specific IgE significantly. And SCRT treated mice showed downward tendency of IgG1, a Th1 relative antibody, level. But, SCRT did not affect levels of antigen specific total antibody and IgG2a, a Th1 relative antibody. Conclusions : we demonstrated the strong possibility of SCRT as a complementary or alternative drug to western drug also demonstrated that regulation of Th1/Th2 imbalance may be one of mechanism contributed to treatment for respiratory disease by SCRT.

  • Purpose: House dust mite (HDM) has been suggested to be the most important aeroallergen responsible for atopic asthma in Korea. We aimed to investigate that specific IgE antibodies to HDM and other common indoor aeroallergens contribute differently to total serum IgE and show different relationships with longitudinal fractional exhaled nitric oxide (FeNO) measurements in Korean atopic asthmatic patients. Methods: A total of 193 children aged 8 to 16 years with intermittent or mild persistent atopic asthma were recruited. Sera were assayed for total IgE and specific IgE antibodies to HDM and other common indoor allergens. FeNO was serially measured 10 times or more over 2 years when subjects were not receiving controller medications. Results: In 152 children who completed the study, IgE antibodies to specific HDM were more prevalent than those to other common indoor aeroallergens. In addition, IgE antibody titers to HDM were the strongest contributor to total IgE increases. Furthermore, only HDM-specific IgE antibody titer significantly correlated with maximum FeNO (r=0.21, P=0.029) and the rate of FeNO higher than 21 parts per billion (ppb) (r=0.30, P=0.002). Eight patients (5%) were found to have maximum FeNO of 21 ppb or less, suggesting the presence of a low FeNO phenotype among atopic asthmatic patients. Conclusion: The quantity of HDM-specific IgE antibody provides a possible explanation for increases of total IgE and significantly correlates with the amount and frequency of FeNO increases in Korean atopic asthmatic patients.

  • Objectives : This study was designed to investigate the effects of alcoholic fermentation beverage using pear, Bae Ro Mi In (BRMI) on airway hyperresponsiveness and immunoglobulin production in asthmatic mice Methods : We investigated the effects of BRMI on airway hyperresponsiveness by measurement of enhanced pause (Penh), and also investigated the effects on production levels of antigen specific antibody and subclasses such as IgG1, IgG2a and IgE by using ELISA methods. Prednisolone (PD, 5 mg/kg) was used as positive control. Results : Treatment with BRMI did not lowered airway hyperresponsiveness, but PD lowered significantly. Oral administration of BRMI lowered production level of ovalbumin (OVA) specific total antibody significantly. Especially, BRMI decreased IgE levels compared to non-treated control effectively. Treatment with PD lowered production levels of total antibody, IgG1 and IgE. Conclusions : These result suggest that BRMI can lower production levels of antigen specific total antibody and IgE in asthmatic mice. We also suggest that BRMI has the possibility to prevent or cure asthma through regulation of antigen specific antibody production.

  • 21명의 간흡충 감염환자 및 15명의 건강인으로부터 혈청을 수집하여 혈청내 IgE와 간흡충에 대한 특이 IgE 항체를 RIST와 RAST법을 이용하여 측정하였다. 간흡충 감염환자 및 건강인의 혈청 IgE와 특이 IgE는 각각 2,372 lU/ml과 364IU/ml 그리고 52.0%와 4.4%로 간흡충 감염자에서 모두 유의하게 상승되어 있었으며 (p<0.001 및 p<0.01), 혈청 IgE의 상승과 특이 IgE의 상승은 상호 밀접한 관계가 있었고(r=0.9451), 혈청 IgE와 EPG(r=0.6056), 특이 IgE와 EPG(r=0.5693) 역시 상관 관계가 있었다. 이상의 결과로 보아 간흡충 감염은 인체 혈청내 IgE 및 특이 IgE항체를 상승시키며, IgE 및 간흡충에 대한 특이 IgK는 숙주-기생충간의 면역반응에 관여할 것으로 생각된다.

  • It has been reported that ginseng is effective in the central nervous system, immune system, and the strong inflammatory responses. However, there has been no research report yet about the effect of ginseng on allergic hypersensitivity reactivity. To confirm the ginseng effects on the release of mediators(histamine. leukotrienes etc.) which cause the hypersensitivity reactivity and inflammatory response, we used actively sensitized guinea pig airway tissues by utilizing the superfusion technique. In this procedure. the contractile response and mediators released after antigen stimulation of sensitized tissues, and IgG and IgE antibody products were measured in sera of immunized animals. Then the results of the controll group were compared to those of ginseng pretreatment groups. In the total saponin(TS) and panaxatriol(PT) pretreatment, histamine release decreased by $20\%$ in the tracheal tissues after active sensitization by ovalbumin(OVA, 10mg/kg), but in the lung parenchyma, histamine release decreased by $40\%.$ Panaxadiol(PD) significantly decreased histamine release by $40\%$ in the both tissues after active sensitization. TS, PT and PD of ginseng poorly blocked leukotrienes (LTs) and prostagrandin $D_2(PGD_2)$ release(less than $10\%$). Ginseng TS and PT had no effect on the serum IgG antibody production by ovalbumin, whereas PD significantly increased serum IgG antibody contents(approximately by 2 times). However, $IgG_1$ antibody products in the serum of guinea pig actively sensitized with ovalbumin after PD pretreatment were decreased, compared to that with ovalbumin alone. IgE antibody production by passive cutaneous anaphylaxis(PCA) titer in the TS pretreatment increased 3 times more than in the absence of TS(PCA titer by PT was not detected). These studies show that some ginseng saponins can in part act to inhibit mediator release in antigen - induced airway smooth muscle by inducing the IgG antibody production which has been changed in the specificity.

  • Background: Recently, the number of domestic pets has increased. As a consequence, sensitization to animal allergens, such as cat or dog allergens, has become a problem. Objective: We studied the annual trends of sensitization to cats or dogs, and the characteristics of the patients. Methods: We retrospectively analyzed the medical records of 7,469 patients who visited a dermatology clinic and underwent an allergic profile test, from January 2011 to December 2015. Specific immunoglobulin E (IgE) levels to cat or dog antibody greater than 3.50 IU/ml were regarded as positive results. Results: In all, 274 patients showed significant increase in levels of specific IgE antibody to dog, and 307 revealed increase in levels of of specific IgE antibody to cat. The prevalence of these specific IgEs increased from 2011 to 2015. Independent risks for sensitization to cat allergens were sensitization to dog, but not to house dust, Dermatophagoides pteronyssinus, and D. farinae. Independent risks for sensitization to dog allergens were sensitization to cat, but not to house dust, D. pteronyssinus, and D. farinae. Total IgE level was not related to specific IgE level against either cats or dogs. Conclusion: In conclusion, the prevalence of sensitization to cat or dog has increased. Sensitization to cat or dog is related to each other, but is irrelevant to the total IgE level.
