윤충 감염시 증가되는 기생충 특이 IgE 항체는 항기생충 작용을 하는 것으로 알려져 있으나 총 IgE 항체의 90% 이상을 차지하는 비특이성 IgE 항체의 역할에 대해서는 잘 알려져 있지 않다 이 실험에서는 폐흡충 감염 마우스에 anti-lgE 단일크론 항체를 처치한 후 혈청내 IfgE. 비장 B 세포 의 $Fc{\varepsilon}RII/CD23$의 발현 및 충체수를 관찰하여 비특이성 IgE가 숙주의 방어면역에 미치는 역할을 알아보았다. Anti-lgE를 처치한 폐흡충 감염 마우스의 혈청내 총 IgE 항체의 양은 실험 기간 동안 억제되어(($<{\;}1{\;}{\mu\textrm{g}/ml}$) PBS로 처치한 감염군에 비해 유의한 수준(P < 0.05)으로 감소되었다 또 한 Anti-IgE를 처치한 폐흡충 감염 마우스에서의 $Fc{\varepsilon}RII/CD23$ 양성인 비장 B 세포수 및 그 발현도 PBS로 처치한 감염군에 비해 실험 기간 동안 유의한 수준(P < 0.05)으로 감소되었다. 충체 회수율에 있어서도 anti-lgE를 처치한 감염 마우스는 6주에 44%로 PBS로 처치한 감염군(75%)에 비해 유의한 수준(P < 0.05)으로 감소하였다. 이상의 결과를 종합할 때 폐흡충 감염 마우스에서 높게 증가되는 비특이성 IgE는 숙주의 방어면역을 방해하여 오히려 충체를 보호하는 역할을 하는 것으로 생각된다.

Enhancement of antigen-specific IgE is a hallmark of allergic hyperresponsiveness, therefore it is necessary to adopt or develop a highly sensitive and specific assay for determination of allergen-specific IgE levels in vivo. In this presentation, we introduce an ELISA (enzyme linked immunosorbent assay) system developed to measure the levels of chicken egg ovalbumin (OVA)-specific IgE in serum. The ELISA method uses a commercially available purified rat anti-mouse IgE as a capture Ab and biotinylated OVA as a detection reagent. Avidin-peroxidase with its substrate is used for color development resulting in optical density measurement at 405 nm. The ELISA system produces a highly sensitive dose-response relation-ship between optical density levels and the dilution titer of the OVA-IgE standard serum but no cross-reaction with unrelated IgE or IgG. It is believed that the system is an Efficient tool to delineate an adjuvant effect of environmental pollutants on development of asthmatic and atopic responses.

Background: IgE is closely related to the development of allergies. However, the poor relationship between the specific IgE level and the severity of allergic diseases suggests the possibility of functionally different IgE isoforms. With this in mind, rat basophilic leukemia (RBL)-2H3 activation was analyzed with each type of rat IgE for two parameters, exocytosis and IL-4 mRNA production. RBL-2H3 has been well documented in the rat mucosal mast cell line. Methods: RBL-2H3 cells sensitized with each kind of rat IgE was activated by cross-linking FcRI with B5 (monoclonal anti-rat IgE mouse IgG antibodies). The RBL-2H3 exocytosis was measured by analyzing the ${\beta}$-hexosaminidase level, and the level of IL-4 mRNA synthesis was analyzed using semiquantitative RT-PCR. Rat IgE, which was produced by a parasite infection (REP), was prepared using either Paragonimus westermani metacercariae (REP-PW) or Anisakis simplex third stage larvae (REP-AS). A rat IgE prototype of IR162 was prepared by a peritoneal injection of immunocytoma. Results: The level of exocytosis showed a linear relationship with the rat IgE concentration when REP-PW or REP-AS was applied. However, it exhibited a biphasic response with IR162. In addition, the time course of heating at $56^{\circ}C$ illustrated the similarity between REP-PW and REP-AS, which differed from that of IR162. In contrast, the level of IL-4 mRNA synthesis in the RBL-2H3 cells with IR162 was comparable to that of either REP-PW or REP-AS. Conclusion: These results suggest that functionally different rat IgE isoforms exists in RBL-2H3 exocytosis.

Atopic dermatitis is one of the most common skin disease in children and a characteristic chronically recurrent form of dermatitis with a hereditary tendency, affecting infants and may extend to the childhood or th the adult age. Environmental factors, stress, and foodstuffs such as milk, egg may cause atopic dermatitis. Nc/Nga mice were used as an animal model for human atopic dermatitis. The divided by 4group such as normal group, BMAC group, FK506 group, MR group for this study raised in conventional conditions. To investigate effect of Chamomile German on atopic dermatitis in NC/Nga mice, the serum IgE and IgG1 level were measured while the severity degree of the skin lesion was examined by the naked eyes of two volunteers who were unaware of the treatment status. The results were the followings. 1. The score on the severity degree of skin dermatitis in FK 506 and MR group was lower than that in control group. 2. The serum IgE level in control group was higher 25% than that in normal group. 3. The serum level of IgE in FK506 and MR group compares to control group was decreased. 4. The serum IgG1 level was decreased more than 3.5 times in FK506 compared to control group while MR group had significantly less the serum IgG1 than control group. From the above results, treatment of Chamomile German oil had the effect on atopic dermatitis in NC/Nga mice. If scientific researches on aroma oil are performed in various way, aroma oil will be used to cure skin dermatitis as a alternative therapy in the future.

Purpose: Conventional serum IgE assay was costly, required the skills of expert, and relied heavily on expensive equipment. Quantitative measurement of total IgE using Point of Care Test (POCT) device can be the solution for these limitations. This study evaluated and validated the reproducibility of ImmuneCheck IgE. Methods: This study included 120 patients of allergic diseases such as allergic rhinitis, asthma, drug allergy, food allergy, atopic dermatitis, or anaphylaxis. The reliability of POCT ImmuneCheck IgE was evaluated by comparing results from the naked eye and from the Q-Reader. Intratest reproducibility and intertest correlation were analyzed using intraclass correlation coefficient (ICC). Results: Of the 120 enrolled patients, 51 were males and 69 were females. The ages ranged from 19 to 84 years, with an average age of 51.5 years. The concentration of serum total IgE measured by Phadia ImmunoCAP IgE ranged from 5.95 to 5,000 IU/mL. ICC for Intratest reproducibility of ImmuneCheck IgE by naked eye and by Q-Reader were 0.991 (P< 0.001) and 0.989 (P< 0.001), respectively. In addition, intertest correlation between ImmuneCheck IgE and Phadia ImmunoCAP IgE results of naked eye and Q-Reader were 0.968 (P< 0.001) and 0.948 (P< 0.001), respectively. Conclusion: The ImmuneCheck IgE was reproducible and highly correlated with conventional Phadia ImmunoCAP IgE assay. This result suggests that ImmuneCheck IgE can be a useful tool for rapid and precise detection of total IgE.

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.

Canine atopic dermatitis (CAD) has a genetic basis and is primarily a skin disorder characterized by allergic features. It is caused by an excessive immune response, associated with immunoglobulin E(IgE), to allergens and shows clinical signs of itching and inflammation. The present study evaluated the allergen-specific and total IgE concentration in dogs with allergic disorders. Allergen-specific IgE analysis was performed using a Multiple Allergen Simultaneous Test (MAST) assay, and total IgE analysis was conducted using an ELISA in 82 dogs with CAD. The subjects were divided into two groups: dogs aged ≤3 years and dogs aged >3 years, enabling a comparison of total IgE concentrations between the two age groups. The results showed that the major affecting environmental allergen was Alternaria alternate, and the major affecting dietary allergen was raw chestnut. The results revealed that dogs aged ≤3 years had higher total IgE concentrations than dogs aged >3 years with significant difference. The results of this study can contribute to the diagnosis and treatment of CAD in South Korea.

Peripheral neuropathy associated with hyper-IgE-emia have been rarely reported. Here we present a 72-year-old man with acute motor axonal neuropathy who had relatively poor prognosis. The serum was weakly positive for IgG GQ1b and GT1a, and serum IgE was significantly elevated. He was transferred to a rehabilitation center with Medical Research Council grade 3 lower extremity weakness on admission day 65. We would suggest that hyper-IgE-emia may increase the magnitude and rate of neural damage in this case.
