Egg allergy has been shown to be the most common food allergy in children with atopic dermatitis. Allergic reactions to proteins derived from egg white (EW) are more common than those derived from egg yolk. Ovomucoid, ovalbumin, ovotransferrin, and lysozyme have been identified as major allergens in EW. This study was conducted to evaluate the effect of EW on immune modulation in an induced allergy mouse model. A total of 50 five-week-old BALB/c male mice were treated with trimellitic anhydride (TMA) for three weeks to induce allergy-like symptoms. The TMA-treated mice were rested for one week and then divided into five groups and fed 0, 10, 50, and 100 mg/d EW for four weeks. All EW consumption groups showed no significant increase or decrease in the populations of white blood cells; however, a significant increase in B-lymphocyte activity was observed in the fourth week. Furthermore, EW consumption did not influence serum immunoglobulin G and immunoglobulin E levels. Taken together, these data demonstrate that the consumption of EW by TMA-treated mice did not increase allergic parameters such as serum IgE level, but enhanced the lymphocyte activities against pathogens. Therefore, this study suggests that the consumption of EW promotes Th2 immune modulation, and EW could be an excellent candidate for maintaining health.

Bovine whey protein expression patterns of colostrum are much different from that of milk. Moreover, bovine colostrum is an important source of protective, nutritional and developmental factors for the newborn. However, to our knowledge, no research has been performed to date using a comparative proteomic method on the changes in the bovine whey proteome during the transition from colostrum to milk. This study therefore separated whey protein of days 1, 3, 7 and 21 after calving using two dimension electrophoresis. Differentially expressed proteins at different collection times were identified using high-performance liquid chromatography in tandem with mass spectrometry (LC/MS) and validated by enzyme-linked immunosorbent assay (ELISA) in order to understand the developmental changes in the bovine whey proteome during the transition from colostrum to milk. The expression patterns of whey protein of days 1 and 3 post-partum were similar except that immunoglobulin G was down-regulated on day 3, and four proteins were found to be down-regulated on days 7 and 21 compared with day 1 after delivering, including immunoglobulin G, immunoglobulin M, albumin, and lactotransferrin, which are involved in immunity and molecule transport. The results of this study confirm the comparative proteomic method has the advantage over other methods such as ELISA and immunoassays in that it can simultaneously detect more differentially expressed proteins. In addition, the difference in composition of milk indicates a need for adjustment of the colostrum feeding regimen to ensure a protective immunological status for newborn calves.

Herein, we report a rare case of hemolytic anemia with reticulocytopenia following intravenous immunoglobulin therapy in a young infant treated for Kawasaki disease. A 2-month-old boy presented with fever lasting 3 days, conjunctival injection, strawberry tongue, erythematous edema of the hands, and macular rash, symptoms and signs suggestive of incomplete Kawasaki disease. His fever resolved 8 days after treatment with aspirin and high dose infusion of intravenous immunoglobulin. The hemoglobin and hematocrit decreased from 9.7 g/dL and 27.1% to 7.4 g/dL and 21.3%, respectively. The patient had normocytic hypochromic anemia with anisocytosis, poikilocytosis, immature neutrophils, and nucleated red blood cells. The direct antiglobulin test result was positive, and the reticulocyte count was 1.39%. The patient had an uneventful recovery. However, reticulocytopenia persisted 1 month after discharge.

Objectives : The aim of this study is to investigate anti-atopic dermatitis effect using ato-tang.Methods : Ato-tang was external treatment to NC/Nga mice for 4 weeks, where atopic dermatitis was induced by DNCB at 1% and 0.4% for 3 weeks. Atopic dermatitis index score was measured using eye observation and picture evaluation. The histopathological change of dorsal skin was observed by hematoxylin and eosin (H&E) staining. Cytokines including IL-4, IL-5 and IL-13 were measured by Luminex or reverse transcriptase polymerase chain reaction (RT-PCR) analysis and immunoglobulin E (IgE) was measured by ELISA reader.Results : The dorsal skin of Ato-tang group showed decrease in erythema, pruritus, dry skin, edema, excoriation, erosion and lichenification level through naked eye observations. Immunoglobulin cell infiltration and the thickness of epidermis were significantly decreased in the dorsal skin compared to control. Production of Th2 cytokines (IL-4, IL-5, IL-13) and IgE level in serum were all significantly decreased, in comparison with control. In addition, mRNA expression level of Th2 cytokines (IL-4, IL-5, IL-13) in spleen was decreased, in comparison with control.Conclusion : The results indicated that external treatment of ato was improved skin barrier function in the symptoms of atopic dermatitis disease. Also, atopic dermatitis factors where cytokine as well as immunoglobulin E in serum and mRNA expression were decreased, respectively, in comparison with control. Therefore, we suggest that ato could be effectively used as a external therapeutic drug based on atopic dermatitis factors.

Purpose: In addition to regulating calcium and phosphorus homeostasis and bone metabolism, vitamin D is known as an immune modulator. Recently, there has been increased worldwide interest in the association between low levels of vitamin D and allergic diseases. The purpose of this study was to assess the relationship between serum vitamin D levels and allergic/vasomotor rhinitis (AR/VR) in children. Methods: This study included 164 patients. The sample included 59 patients with AR, 42 patients with VR, and 63 controls. Their ages ranged from 0 to 16 years. We examined the levels of 25-hydroxyvitamin D, Immunoglobulin E, specific IgE, and eosinophil cationic protein; peripheral blood eosinophil count; and the results of a skin prick test. Results: Serum 25-hydroxyvitamin D levels were $19.0{\pm}8.5ng/mL$ in the AR group, $25.5{\pm}10.9ng/mL$ in the VR group, and $26.9{\pm}10.7ng/mL$ in the control group. After adjustment for body mass index and season at the time of blood sampling, vitamin D levels in the AR group were lower than those of the VR group (P=0.003) and control group (P<0.001). Vitamin D levels were inversely correlated with Immunoglobulin E levels (r=-0.317, P<0.001). AR patients with food allergy or atopic dermatitis did not have lower levels of 25-hydroxyvitamin D than AR patients without these diseases. Conclusion: This study demonstrates a possible relationship between vitamin D levels and allergic rhinitis in Korean children.

Purpose: To evaluate whether the levels of immunoglobulin G (IgG) antibody to Tanerella forsythia are associated with periodontal status. Methods: Patients with a diagnosis of chronic periodontitis were considered candidates for the study; thus 80 chronic periodontitis patients and 28 healthy persons (control group) were invited to participate in this investigation. The presence of T. forsythia was detected by polymerase chain reaction (PCR) analysis using primers designed to target the respective 16S rRNA gene sequences. Peripheral blood was collected from each subject to identify the IgG1 and IgG2 serum antibodies against T. forsythia. All microbiological and immunological laboratory processes were completed blindly, without awareness of the clinical status of the study patients or of the periodontal sites tested. Results: The bivariate analysis showed that lower mean levels of clinical attachment level (CAL) and probing depth were found in the presence of the IgG1 antibody titers against whole-cell T. forsythia; however, only the difference in CAL was statistically significant. In the presence of the IgG2 antibody titers against whole-cell T. forsythia, the periodontal parameters evaluated were higher but they did not show statistical differences, except for plaque. The unadjusted linear regression model showed that the IgG1 antibody against whole-cell T. forsythia in periodontitis patients was associated with a lower mean CAL (${\beta}=-0.654$; 95% confidence interval [CI], -1.27 to -0.28; P<0.05). This statistically significant association remained after adjusting for possible confounders (${\beta}=-0.655$; 95% CI, -1.28 to -0.29; P<0.05). On the other hand, smoking was a statistically significant risk factor in the model (${\beta}=0.704$; 95% CI, 0.24 to 1.38; P<0.05). Conclusions: Significantly lower mean levels of CAL were shown in the presence of the IgG1 antibody titers against whole-cell T. forsythia in periodontitis patients. Thus, the results of this study suggest that IgG1 antibody to T. forsythia may have been a protective factor from periodontitis in this sample.

Electrical acupuncture has been shown to induce hypoglycemic effect in streptozotocin diabetic rats. The Zusanli acupoints have been widely used in traditional Chinese medicine to relieve symptoms of diabetes mellitus. But, the effects of electrical acupuncture stimulation of different frequencies are still unclear. We designed an experiment to investigate the effect of electrical acupuncture of high (100 Hz) and low (2 Hz) frequencies on Zusanli acupoint for 15 minutes in streptozotocin diabetic rats. They were divided into 4 groups, high frequency electrical acupuncture (HFEA group, n=5), low frequency electrical acupuncture (LFEA group, n=5), without any treatment (control group, n=5) and normal group (n=5). After 2 weeks of treatment, the HFEA and LFEA groups had a significantly decreased glucose concentration in serum in comparison to the control group. Additionally, the HFEA group had a significantly decreased glucose concentration in serum compared with the LFEA group. Both the HFEA and LFEA groups had a significantly decreased Immunoglobulin G concentration in serum compared with control group. The LFEA and control groups had a significantly increased cholesterol concentration in serum compared with the normal group, but the HFEA did not have a significantly increased cholesterol concentration. Thus we suggest that electrical acupuncture stimulation at the Zusanli acupoints is effective on hypoglycemic effect and immune function. Overall, the therapeutic effects of electrical acupuncture at 100 Hz was better than effects at 2 Hz.

Protein carboxylmethylation methylates the free carboxyl groups in various substrate proteins by protein carboxyl O-methyltransferase (PCMT) and is one of the post-translational modifications. There have been many studies on protein carboxylmethylation. However, the precise functional role in mammalian systems is unclear. In this study, immunoglobulin, a specific form of $\gamma-globulin$, which is a well-known substrate for PCMT, was chosen to investigate the regulatory roles of protein carboxylmethylation in the immune system. It was found that the anti-BSA antibody could be carboxylmethylated via spleen PCMT to a level similar to $\gamma-globulin$. This carboxylmethylation increased the hydrophobicity of the anti-BSA antibody up to 11.4%, and enhanced the antigen-binding activity of this antibody up to 24.6%. In particular, the Fc region showed a higher methyl accepting capacity with 80% of the whole structure level. According to the amino acid sequence alignment, indeed, 7 aspartic acids and 5 glutamic acids, as potential carboxylmethylation sites, were found to be conserved in the Fc portion in the human, mouse and rabbit. The carboxylmethylation of the anti-BSA antibody was reversibly demethylated under a higher pH and long incubation time. Therefore, these results suggest that protein carboxylmethylation may reversibly regulate the antibody-mediated immunological events via the Fc region.

Objective: The survival of a semi-allogeneic fetus depends on several immunological mechanisms, and it has been suggested that recurrent pregnancy loss (RPL) could develop as a result of one or more immunological abnormalities. Methods: Compatibility between partners for human leukocyte antigen (HLA) genotypes and the relationships between maternal killer-cell immunoglobulin-like receptor (KIR) and paternal HLA-Bw4/Bw6 and HLA-C1/C2 supra-groups were investigated in 25 couples with RPL in comparison to healthy couples with children. HLA and KIR genotyping was performed using polymerase chain reaction with sequence-specific primers and/or sequence-specific oligonucleotides. Results: HLA class I incompatibility between partners, especially in HLA-B alleles, was more common in the RPL group (p= 0.01). HLA-C2 homozygosity was more frequent in the male partners of RPL couples than in other groups (p= 0.03). The KIR2DL5 gene frequency was significantly higher in both the female and male partners of RPL couples, whereas the KIR2DS3 gene frequency in male partners of RPL couples was significantly reduced (p= 0.03). The presence of KIR2DL3 in women with RPL was correlated with the presence of HLA-C2 alleles in their spouses (p= 0.03). Conclusion: Our data from a Turkish population suggest that male HLA-C2 homozygosity may play an important role in RPL. Additionally, an incidental match between male HLA-C2 and female HLA-C1 ligand KIR receptors might perturb the balance between activatory and inhibitory KIR-ligand interactions during pregnancy in couples affected by RPL. The roles of orphan KIR2DL5 and orphan KIR2DS3 in RPL remain obscure.
