수은($HgCl_2$)이 마우스의 면역계에 미치는 영향을 밝히고자 Balb/c 마우스를 대상으로 시험관내 및 생체내 단계적 시험을 실시하였다. Lipopolysaccharide, pokeweed mitogen 및 phytohemagglutinin 등의 미토겐(mitogen)에 대한 비장세포의 반응성은수은농도에 의존적으로 억제되었다. 수은에 의한 비장세포의 증식반응억제는 배양기간 중 수은 노출시기에 관계 없었으며 수은 전처치에 의해서도 그 증식반응은 억제되었다. 그러나 수은은 pokeweed mitogen으로 유도한 비장세포의 항체생산은 항진시켰다. 실험동물을 음용에 의하여 수은에 3주간 노출시켰을 때 투여기간 중 체중의 증가는 현저히 둔화되었으나, 흉선 및 비장의 무게, 신장, 골수, 비장 및 슬와 림프절의 병리학적 변화는 유발되지 않았다. 그러나 혈청 면역 글로불린(immunoglobulin) 농도는 현저히 증가되었다. 증가된 혈청 $IgG_1$및 IgE농도는interleukin-4 (IL-4)에 대한 항체투여로 현저히 감소되었다. 수은투여 마우스의 면양적혈구(SRBC)에 대한 항체반응을 측정한 결과 면양적혈구에 대한 총응집소가에는 대조군의 그것과 차이가 없었으나 혈청 IgM 및 IgG농도는 오히려 대조군의 그것보다 현저히 높았다. 이상의 성적들은 수은의 면역계에 대한 독작용은 그 측정방법에 따라 다를 수 있으며, 수은노출에 따른 림프조직의 병변이 발생하기 전에 면역계의 기능적 변화가 일어나고, 수은에 의한 혈청 면역 글로불린 농도의 증가는 특정항원에 대한 항체반응과는 무관할 수 있는 등 수은이 면역반응에 이상을 초래함을 시사한다.

Purpose: This study aims to determine the efficacy and safety of house dust mite (HDM)-sublingual immunotherapy (SLIT) in elderly patients with AR. Methods: A total of 45 patients aged ${\geq}60years$ with HDM-induced AR who had ${\geq}3$ A/H ratio on skin prick test and/or ${\geq}0.35IU/L$ to both Dermatophagoides farinae and Dermatophagoides pteronyssinus by ImmunoCAP were enrolled in 4 university hospitals. To evaluate additional effects of HDM-SLIT, they were randomized to the SLIT-treated group (n = 30) or control group (n = 15). Rhinoconjunctivitis total symptom score (RTSS), rhinoscopy score, Korean rhinoconjunctivitis quality of life questionnaire, rhinitis control assessment test, asthma control test scores, and adverse reactions, were assessed at the first visit (V1) and after 1 year of treatment (V5); for immunological evaluation, serum levels of HDM-specific immunoglobulin A/IgE/IgG1/IgG4 antibodies and basophil response to HDMs were compared between V1 and V5 in both groups. Results: There were no significant differences in demographics, RTSS, skin reactivity to HDMs, or serum total/specific IgE levels to HDMs (P > 0.05, respectively) between the 2 groups. Nasal symptom score and RTSS decreased significantly at year 1 in the 2 groups (P < 0.05). There were no significant differences in percent decrease in nasal symptom score and RTSS at year 1 between the 2 groups (P > 0.05); however, rhinoscopic nasal symptom score decreased significantly in the SLIT-treated group (P < 0.05). Immunological studies showed that serum specific IgA levels (not specific IgE/IgG) and CD203c expression on basophils decreased significantly at V5 in the SLIT-treated group (P = 0.011 and P = 0.001, respectively), not in the control group. The control group required more medications compared to the treatment group, but there were no differences in adverse reactions. Conclusions: It is suggested that HDM-SLIT for 1 year could induce symptom improvement and may induce immunomodulation in elderly rhinitis patients.

Objectives : Allergic rhinitis is an inflammation or irritation of the mucous membranes that in the nose. Common symptoms include sneezing; a stuffy or runny nose; itch eyes, nose and throat; and watery eyes. We aimed to determine therapeutic effect of Onpye-tang by observing changes in blood cells and the nasal mucosal tissue. Methods : Twenty-four Sprague-Dawley rats were divided into three groups: normal, control, and sample group. Allergic rhinitis was induced in the control and sample group by intraperitoneal and intranasal sensitization with 0.l% Ovalbumin solution. Then Onpye-tang was orally administered only to the sample group for 28days, while the rats in the control group was given normal saline. We observed changes in the number of RBC and WBC; changes of neutrophils, lymphocyte, monocyte, and eosinophil proportions; total IgE level and AST & ALT change; also, changes in the nasal mucosal tissue. We used Student T-test statistically(p<0.05). Results : Onpye-tang showed significantly decreased IgE level on the serum of the rat model. Onpye-tang showed significantly decreased eosinophil level on the blood of the rat model. Onpye-tang inhibited the inflammatory reaction on the nasal mucosal tissue, according to nasal mucosal biopsy. Onpye-tang showed an inhibitory effect on the process of allergic rhinitis, according to IgE level, Eosinophil level, nasal mucosal biopsy. Onpye-tang had no hepatoxicity, according to AST and ALT on the serum. Conclusion : According to the above results, it is considered that Onpye-tang has an inhibitory effect on the process of allergic rhinitis and it can be used in relieving symptoms of allergic rhinitis.

임상증상 없이 검변을 통하여 검출된 이질아메바 포낭양성자를 어떻게 다루어야 할지 오랫동안 논란이 있었으나 이중에서 병원성이 강한 이질아메바(E. histolytica)만 치료하고 병원성이 없는 동형아메바(E. dispar)는 치료하지 않는 것으로 의견이 모아져 있다. 따라서 이 두 종을 감별하는 것이 실제적으로 중요하게 되었고 이를 위하여 동위효소 분석 유전자 분석. 혈청학적인 검사가 가능하다. 그러나 앞의 두 분석법은 원충을 배양하여야 가능하기 때문에 적용하기 어려운 경우가 많아 혈청학적인 감별이 실제적으로 유용하다. 이 연구는 우리 나라에서 무균배양에 성공한 이질 아메바 YS-27의 항원성을 확인된 아메바 감염자 혈청과 면역이적법으로 검증하고. 이를 이용하여 무증상 포낭배출자에서 두 종의 감염을 감별하고자 하였다. 시스테인계 단백질분해효소 억제제인 E64를 첨가한 이질아메바의 항원은 117. 110. 99. 68. 66. 60. 54. 52 46. 45 kDa 분획이 이질아메바 감염이 확인된 사람의 혈청내 IgG 항체와 반응하였고 동형아메바 대장아메바 Beastnystis 및 대조군의 혈청과는 117 kDa 분획이 미약하게 반응하였다. 포낭양성자의 혈청내 IgA 항체와 많은 분획이 반응하였으나 두 종 양성자간에 차이가 없었고 혈청내 IgM과 IgE 항체와 반응하는 분획이 없었다. 동형아메바의 항원은 두 종 양성자 혈청내 모든 군의 항체와의 반응에서 두종을 감별하지 못하였다. 따라서 이질아메바의 항원과 혈청내 IgG 항체 반응이 두 아메바 감염 을 감별할 수 있었다. 증상이 없는 포낭배출자 24명의 혈청을 면역이적 반응시킨 결과 2명에서 46 과 45 kDa 분획을 제외한 다른 모든 분획과 반응하여 이질아메바 감염자로 확인하였고 22명은 동 형아메바 양성자로 확인하였다. 이 자료를 토대로 하면 우리 냐라에서 검출되는 단순 포낭배출자 의 90% 이상은 이질아메바가 아니라 동형아메바 감염자이고. 이에 따라서 포낭양성자 중 환자가 많지 않은 사실을 설명할 수 있을 것이다. 이질아베바 조항원을 이용한 면역이적법은 증상이 없는 아메바 포낭배출자 중 치료를 꼭 필요로 하는 사람을 찾아내는 방법으로 유용함을 확인하였다.

We report 5 cases of ocular toxocariasis in Korean adults complaining of visual impairment along with floating or bubbling sensation. Fundoscopic examination revealed a retinal detachment along with exudate in 4 cases. They all showed typical reaction by ELISA and immunoblot against Toxocra excretory-secretory antigen. One case showed high level of anti-Toxocara IgE antibodies (34.000 Toxocara units/L) as well as increased level of serum total IgE antibodies and the specific IgE antibodies for 3 inhalant antigens, suggesting that high level of anti-Toxocara IgE antibodies was associated with an atopic status. Clinical manifestations were improved after the sequential use of steroids then mebendazole. We also suggest that ocular toxocariasis should be thoroughly investigated even when an evocative uniocular inflammatory lesion is encountered in peripheral retina without a systematic disease.

Background & Objectives : Allergic rhinitis is an inflammation or irritation of the mucous membranes that line the nose. Common symptoms include sneezing, a stuffy or runny nose, itchy eyes, nose and throat, and watery eyes. We aimed to determine therapeutic effects of Tribulus terrestris by observing changes of total IgE level and the scratching or rubbing around the nose behavior. Materials and Methods : Fifteen BALB/c mice were divided into three groups : AR group(allergic rhinitis elicitated), TT group(which ate herbal medicine) and AH group(which ate antihistamine). Allergic rhinitis was induced in the three groups by intraperitoneal and intranasal sensitization with 0.1% ovalbumin solution. Then Tribulus terrestris was orally administered only to the TT group of 28days, while the AH group was given antihistamine. We observed changes of total IgE level and the scratching or rubbing around the nose behavior. We used Kruskal-Wallis test statistically(p<0.05). Results : 1. Tribulus terrestris showed significantly decreased IgE level on the serum of the rat model. 2. Tribulus terrestris showed significantly decreased scratching or rubbing around the nose behaviors of the rat model. Conclusion : According to the above results, it is considered that Tribulus terrestris has an inhibitory effect on the process of allergic rhinitis and it can be used in relieving symptoms of allergic rhinitis.

Objectives : Tongqiao-tang(TQT) has been commonly used for the treatment of common cold, rhinitis etc. Nowadays, TQT becomes one of the most frequently used medicines for allergic rhinitis, but the mechanism of TQT in vivo isn't investigated yet. This study was performed to investigate the effect of TQT on OVA-induced allergic rhinitis mouse model by calculating serum cytokines and IgE. Methods : 8 weeks aged male BALB/c mice were divided into three groups: the normal group, the control group and the medicated group (the TQT group). Each group was consisted of 15 mice. The TQT group was administered TQT extract orally one time a day (1g/kg) from the $1^{st}$ day of experiment till the $26^{th}$ day. The control group and the normal group were administered normal saline by the same method of the TQT group. To induce the allergic rhinitis in the control group and the TQT group, mice of each group were sensitized intraperitoneally with ovalbumin (OVA) solution at the $1^{st}$, the $7^{th}$ and the $14^{th}$ day. After then, intranasal sensitization was performed by dropping 0.1% OVA solution in nasal cavity at the $22^{th}$, the $24^{th}$ and the $26^{th}$ day. At the $27^{th}$ day, the mice were killed and the changes of interferon-${\gamma}$, interleukin-4, interleukin-5, total IgE and OVA-specific IgE were checked. Results : IFN-${\gamma}$ was increased 36% more in the TQT group than that in the control group. IL-4, IL-5, the total IgE and OVA-specific IgE were decreased in the TQT group as compared with the control group and these results were statistically significant. Conclusions : Considering the above experimental results, this study showed that TQT could reduce the allergic reaction in allergic rhinitis. Advanced studies are required to investigate the further mechanisms of TQT.
