  • 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.

  • Recently, it was reported that Pfaffia paniculata, known as Brazil ginseng, caused occupational asthma. To assess a potential relationship between Korean ginseng and allergic reactions, total IgE in serum, allergologic parameter, was investigated. Serum total IgE were measured in 8 takers of ginseng for more than 5 yr, 4 subjects of weak constitution, 10 workers participated in the washing of fresh ginseng in factory and 7 control subjects, Blood samples were taken before and after the scheduled exposure to Korean ginseng, sera were kept frozen until assay. Total IgE levels after the scheduled exposure to Korean ginseng were not significantly different in each group and total IgE levels were not significantly different in the control subjects compared with those of other groups at the start of experiment and at the end of experiment. These results suggest that the exposure to Korean ginseng dose not affect significantly the IgE immune response in volunteers. No changes of levels of IgE on the exposure of Korean ginseng may represent additional evidence of the lack of antigenic potential of Korean ginseng.

  • 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.

  • Immunoglobulin E (IgE) plays an important role in the development of allergic disorders including asthma. Cigarette smoking was reported to elevate serum IgE level and air pollutants such as $NO_{2}$ have been reported to modulate the immune system including inflammation. Moreover, genetic polymorphisms of glutathione S-transferases (GSTs) were reported to affect inflammatory diseases including asthma. Therefore, in the present study we tried to investigate whether tobacco smoke or $NO_{2}$ exposure increases the level of IgE and the GST gene polymorphisms are associated with change of IgE level due to tobacco smoke or $NO_{2}$ exposure. We measured urinary cotinine, personal $NO_{2}$ exposure, and serum IgE levels in 300 healthy university students without allergic disorders. Allelic loss of the GSTM1 and GSTT1 and the GSTP1 (lle105Val) polymorphism were determined by PCR and RFLP. Total serum IgE levels were significantly different according to urinary cotinine levels (P=0.046), while $NO_{2}$ passive dosimeter level and genetic polymorphisms of three GSTs were not associated with total IgE level. Moreover, subjects with cotinine $500\;{\mu}g/g$ creatinine or more showed the highest level of total IgE when they had null type of GSTM1, null type of GSTT1, or variant type of GSTP1 (P<0.05). When we considered IgE level according to urinary cotinine levels in strata with the combinations of GSTM1, GSTT1, and GSTP1 genetic polymorphisms, the subjects with GSTM1 null, GSTT1 null, and GSTP1 variant types showed the largest difference between IgE levels of subpopulations according to cotinine levels (P=0.030). However, there was no significant difference between IgE levels of subpopulations according to $NO_{2}$ passive dosimeter levels in any group with combinations of GSTM1, GSTT1, and GSTP1 polymorphisms. This result suggests that smoking increases allergic response measured as IgE level and combinations of the GSTM1, GSTT1, and GSTP1 polymorph isms modify the effect of smoking on serum IgE level.

  • 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.

  • Cortex Mori, the root bark of mulbery tree has been used as an antiphlogistic, diuretic, and expectorant in herbal medicine. The purpose of this study is to evaluate chicken gamma globulin (CGG)-specific IgE-induced morphologic and functional changes in rat peritoneal mast cells (RPMC), and to determine whether Cortex Mori could inhibit the CGG-specific IgE-depeildent mast cell degranulation and histamine release from RPMC. Results are 1) the degranuration and histamine release from RPMC were not induced within 1 hour after addition of Cortex Mori alone, 2) the CGG and CGG-specific IgE-Induced degranulation from RPMC was observed within 10 minutes, 3) the histamine release from RPMC sensitised with CGG-specific IgE was induced by tile addition of CGG, 4) CGG-specific IgE-dependent degranulation rate in RPMC pretreated with Cortex Mori was significantly Inhibited, compared to that of control group without Cortex Mori pretreatment, and 5) the CGG-specific IgE-dependent histamine release from RPMC was significantly inhibited by pretreatment with Cortex Mori. These data suggest that Cortex Mori contains some substances with capabilities to inhibit CGG-specific IgE-dependent degranulation and histamine release from RPMC.

  • This study was carried out to evaluate the application of food irradiation technology as a method for reducing milk allergies. Bovine $\alpha$-casein, $\beta$-casein, $textsc{k}$-casein, $\alpha$-lactalbumin(ALA), $\beta$-lactoglobulin (BLG) and serum albumin (BSA) were used as model allergens of milk proteins and the proten solution (2.0 mg/mL) with 0.01 M phosphate buffered saline (pH 7.4) was irradiated at 3, 5 and 10 kGy. Using milk-hypersensitive patients IgE (MHP-IgE), the changes of binding ability to irradiated proteins were observed by competitive indirect enzyme-linked immunosorbent assay (Ci-ELISA). Affinity of MHP-IgE to milk proteins was higher in ALA and BLG than that of other proteins. Standard curve to each non-irradiated protein could be made with MHP-IgE for quantifying milk allergens. Binding abilities of MHP-IgE to the irradiated proteins, however, decreased with different slopes of the standard curves. Sensitivity of gamma irradiation was higher in ALA and BLG than of other proteins. These results indicated that irradiation technology can be used to reduce the milk hypersensitivity.

  • 어류의 세균성질병 원인체인 Edwardsiella tarda 감염의 예방과 치료에 E. tarda로 면역한 계란으로부터 얻어진 난황항체 (IgY)의 잠정적인 사용을 평가하였다. PEG법으로 정제된 IgY는 64 kDa의 heavy chain과 27 kDa의 light chain을 가지고 있었다. IgY는 사료 공급 후 위의 pH가 3.4로 낮아지는 2시간째에는 대부분의 활성을 상실하였으나, 장내에서는 IgY의 활성이 나타났다. IgY의 효능 실험 결과 감염 초기에 IgY를 20 mg/fish로 공급한 그룹은 모든 실험에서 대조 그룹에 비해 높은 생존율을 나타내었으며, 장기 내에서 균의 감염 정도 역시 낮았다. 그러나 감염 후기에서는 생존율에 있어서의 유의적인 차이를 확인하기 힘들었다. 이는 넙치의 위에서 대부분의 IgY가 활성을 잃어 낮은 농도만이 장으로 이동하기 때문일 것으로 사료되며, 이 농도에서 IgY는 E. tarda에 대한 뚜렷한 예방이나 치료의 효과 보다는 감염시기를 어느 정도 연장시키는 역할을 하는 것으로 추정된다.

  • Background: Although a skin test is the primary option for detecting allergen-specific IgE in clinics, the serum IgE immunoassay is also important because it allows for the diagnosis of allergy without any accompanying adverse effect on the patient. However, the low detection limit of IgE levels by immunoassay may restrict the use of the method in some occasions, and improving its sensitivity would thus have a significant implication in allergy-immunology clinics. Methods: In this study, we attempted to detect specific serum IgE by using immuno-polymerase chain reaction (IPCR) which combines the antigen-antibody specificity of enzyme-linked immunosorbent assays (ELISAs) with the amplification power of PCR. Results: Our results demonstrated that Blo t5-specific serum IgE can be detected by IPCR with a 100-fold higher sensitivity than ELISA, and cross-reactivity of serum IgE to other mite allergens is able to be analyzed by using only $0.3{\mu}l$ of serum sample. Use of real-time IPCR seemed to permit more convenient determination of specific serum IgE as well. Conclusion: We believe that IPCR can serve as a valuable tool in determining specific serum IgE, especially when the amount of serum sample is limited.

  • Objectives : This study was aimed to evaluate the correlation between changes in disease severity and serum total IgE or eosinophil count in individual patients of atopic dermatitis depending on the change of severity. Methods : We performed a retrospective chart review of 8 cases of atopic dermatitis who underwent blood tests more than five times. Disease severity was assessed by objective SCORing of Atopic Dermatitis index (OSI). Blood tests include serum total IgE, eosinophil counts, aspartate aminotransferase (AST), alanine aminotransferase (ALT), blood urea nitrogen (BUN) and serum creatinine (SCr). In each subject, on the day that the blood test was performed, OSI was also assesed by a same physician. Correlation between OSI and total IgE or eosinophil count was analysed by nonparametric correlation analysis. Results : There was a statistically significant positive correlation between OSI and total IgE in three cases and a positive correlation between OSI and eosinophil count in two cases. In other three cases, there were no significant correlation. There were no cases that OSI correlated with total IgE and eosinophil count at the same time. In all cases, AST, ALT, BUN and SCr were stable. Conclusions : We suggest that total IgE and eosinophil count may reflect the severity of atopic dermatitis differently in individual patients. We also suggest that total IgE and eosinophil counts may be used as biomarkers to predict the severity of atopic dermatitis in some patients depending on the underlying pathology.
