Allergy is conditions when a hypersensitivity reaction happens with a certain element, called as an allergen, which is commonly not reactive to ordinary individuals. Allergic diseases involve various organs or systems in the body. The purpose of allergy tests is to make a diagnosis of allergic diseases and to identify the affecting allergens. In vivo tests, more relevant in clinical situation, include skin test, patch test and provocation test. In in vitro tests, there are specific IgE test, histamine releasing assay, and lymphocyte activation test, safer and more objective than in vivo tests. In the view point of clinical practice, skin test, provocation test, total IgE test and specific IgE test were reviewed in depth.

Purpose. Natural herb has been used for traditional medicine for thousands of years. For this reason, alternative medicine methods affect to domestic animal field. The main purpose of this study was to confirm the regulated proteins after feed additive treatment. Methods. We used total thirty male pigs were used for this experiment. E. coli and Salmonella typhimurium, were used for promote enteritis. Animals were divided into a negative control group, positive control group and test group to determine the effect of an additive mixture on the changes in protein expression in serum. The pigs were given a food supplemented with a natural herbal additive containing immunoglobulin yolksac (IgY) at concentrations 1%. On the 1st week and after eight weeks of feeding, the serums were collected from each group. The changes in the serum proteome as a response to the herbal additive were examined using two-dimensional polyacrylamide gel electrophoresis. Results. A total of 14 differentially expressed protein spots were identified by comparing the protein profiles of the control and additive treated porcine serums. Finally, 7 proteins were detected by MALDI-TOF/MS. Moreover, the proteins detected are involved in a cholesterol control factor, inflammation regulator, Conclusion. These results support of the hypothesis that a natural herbal additive containing IgY can affect the immune regulation system and reduce the pathological process by microbial infections.

The Immunoglobulin $IgG_1$ and $IgG_2$ isotype immune responses of domestic ruminants and mice to Cowdria. ruminantium live infection or by immunization with inactivated organisms were determined by the enzyme linked immunosorbent assay and Western blotting. Immunization of goats with inactivated elementary bodies (IEBs) led to a predominant $IgG_1$ isotype response. This indicated that a Th2 response was induced. After challenge, the IgG isotype responses were mixed whereby both $IgG_1$ and $IgG_2$ antibodies were detected. Two goats that survived virulent challenge had a predominant $IgG_2$ isotype response. In cattle live infection by natur l challenge or experiment led to a predominant $IgG_1$ isotype response. Immunization of cattle with IEBs however led to mixed IgG responses characterized by similar $IgG_1$ and $IgG_2$ ratios. In the mouse live infection led to a predominant $IgG_2$ isotype response. This indicated the mouse developed a true Th1 type cell mediated immune response when inoculated with live organisms. Immunization with inactivated organisms on the other hand led to a dominant $IgG_1$ response. It is evident from this work that the immune responses of ruminants and mice to C. ruminantium are different and that using mice as the experimental model for immune responses to Cowdria ruminantium. is not the appropriate.

To enhance the production of heavy chain immunoglobulin G (HC IgG) in the suspension cultures of transgenic tobacco cells (Nicotiana tabacum), the effects of adding various cytokinins (i.e., growth regulators) and organic nitrogen sources to culture media were investigated. Four different cytokinins including kinetin, isopentenyladenine (IPA), 6-benzylaminepurine (BA), and zeatin were tested with or without dichlorophenoxyacetic acid (2,4-D), which is a typical growth regulator supplemented in the standard Murashige and Skoog (MS) medium. The productivity of intracellular HC IgG was increased by 36 and $42\%$, compared to the control, especially when IPA (2 mg/l) or BA (0.2 mg/l) was added to the media in the presence of 2,4-D, respectively. In the study of organic nitrogen sources, addition of each casein hydrolysate and tryptone to the culture media at a final concentration of 0.01 and 1 g/l, respectively. increased the productivity or he IgG as much as 68 and $67\%$, respectively, in comparison with the control, which was is MS medium without supplementation of any organic nitrogen sources. This study shows that the optimization of media composition could offer significant improvements in the production of foreign proteins in the suspension cultures of transgenic plants.

The aim of this study was to evaluate efficacies of selected lactic acid bacteria (LAB) in inducing immunoglobulin A (IgA) secretion. Twenty-five different LAB isolated from traditional fermented Korean foods were characterized for their probiotic properties and screened to identify those that could stimulate lamina propria cells (LPCs) from Peyer's patch to secret IgA in vitro. Among them, four strains (Lactiplantibacillus plantarum CJW55-10, Lactiplantibacillus pentosus CJW18-6, L. pentosus CJW56-11, and Pediococcus acidilactici CJN2696) were found to be strong IgA inducers. The number of IgA positive B cells and soluble IgA level were increased when LPCs were co-cultured with these LAB. Expression levels of toll-like receptor (TLR) such as TLR2 and TLR4 and secretion of interleuckin-6 were augmented in LPCs treated with these LAB. Further, we determined whether oral intake of these LAB enhanced IgA production in vivo. After one-week of daily oral administration, these LAB feed mice increased mucosal IgA and serum IgA. In conclusion, selected strains of LAB could induce systemic IgA secretion by activating lamina propria B cells in Peyer's patch and oral intake of selected strains of LAB can enhance systemic immunity by inducing mucosal IgA secretion.

Multisystem inflammatory syndrome in children (MIS-C) is a rare complication of coronavirus disease 2019 (COVID-19), causing multi-organ damage affecting the heart, lungs, kidneys, digestive tract, and nervous system. As the cases of MIS-C have been increasing following the COVID-19 pandemic, the importance of appropriate management for MIS-C is becoming increasingly apparent. Immunomodulating agents such as anakinra, infliximab, and steroids are regarded as supplementary therapy to the first-line treatment with intravenous immunoglobulin. However, these immunomodulating therapies can potentially precipitate opportunistic infections, including those caused by cytomegalovirus (CMV), Epstein-Barr virus, and tuberculosis, or increase the risk of co-infections. Herein, we report a case of a 3-year-old boy who was treated with immunoglobulin, infliximab, and high-dose methylprednisolone for MIS-C, and subsequently developed a persistent fever lasting 32 days caused by a CMV infection.

The effects of aroma mixed oil with Chamomile, Lavender and Sandalwood on atopic dermatitis in NC/Nga mice were examined. The NC/Nga mice were divided into BMAC group, FK 506 Oinment (Tacrolimus Hydrate) group, and CLS group to get curative power of CLS. The amount of total IgE and IgG1 was measured and the severity of atopic dermatitis was assessed by the scoring procedure in NC/Nga mice. Topically applied CLS significantly suppressed the level of serum IgE and IgG1 in NC/Nga mice and FK506, used as reference drugs for atopic dermatitis, also exhibited suppressive effects against level of IgE and IgG1. The level of IgE was lower in the CLS group than in the FK506 group while the serum IgG1 level in the FK506 group was lower than in the CLS group. The treatment with FK506 and CLS reduced the skin inflammation index, especially the severity degree of atopic dermatitis in the skin lesioned NC/Nga mice by naked eyes was improved by treatment of FK506 and CLS. The results suggest that treatment of CLS in NC/Nga mice with atopic dermatitis have an beneficial therapeutic effects on reducing the level of IgE and IgG1 and accelerating repair of skin lesion.

Objective : The water extract of Bojungikgi-tang (BTE) composed with Ginseng Radix, Astragali Radix, Angelicae gigantis Radix, Atractylodes Rhizoma alba, Aurantii nobilis Pericarpium, Glycyrrhizae Radix, Cimicifuga Rhizoma, and Bupleuri Radix and it has been traditionally used for chronic diseases or weakness after illness in oriental countries. However, little is known about the effects of aqueous extract of BTE on trimellitic anhydride (TMA)-induced contact hypersensitivity (CHS). Therefore, the aim of this study was to investigate the effects of BTE on TMA-induced CHS in BALB/c mice.Methods : In this study, the extract of BTE was prepared by extracting with distilled water at 100℃ for 2.5 h. The extract was freeze-dried following filtration through 0.45 μm filter. Mice were orally administrated with or without BTE extract of different doses (25-200 ㎎/㎏/day) for 28 days. During the challenge period, mice were externally applied with different doses of BTE extract one time per day 30 min before TMA treatment. I examined the effects of BTE on the serum levels of IgE, IgG1, IgG2a, and IgG2b, nitric oxide (NO) and prostaglandin E₂ (PGE₂) production in isolated peritoneal macrophages, Th2 cytokine production in isolated spleen cells, ear swelling responses, and the leukocyte infiltration induced by TMA.Results : The orally and externally administration of BTE dose-dependently reduced the serum levels of hapten-specific immunoglobulin E (IgE), IgG1 titer, and PGE₂ production as well as ear swelling responses and leukocyte infiltration in TMA-induced BALB/c mice. The levels of NO and PGE₂ production from peritoneal macrophages stimulated with TMA-BSA were markedly suppressed by pretreatment with BTE in a concentration dependent manner. Furthermore, the levels of Th2 cytokines (IL-4, IL-5, IL-13) production from spleen cells stimulated with ConA were markedly suppressed by BTE treatment in a concentration dependent manner.Conclusions : These results suggest that BTE treatment suppresses chronic contact hypersensitivity, and it can be assumed that the suppression of ear swelling, serum IgE, NO and PGE₂ levels, leukocyte infiltration, and Th2 cytokines in an animal model. Therefore, these properties may contribute to the strong anti-CHS response effect of BTE.
