Hypericin (HyH) is a substance which is isolated a medicinal herb, Hypericum perforatum L., commonly known as St. John's Wort. Hypericum erectum is a long-lived herb that is distributed in Korea. Cloned HyH genes H. erectum of were conformed by sequencing. The cDNA Hyp-1 sequence has 732 bp with an open reading frame of 567. Thus coding for a protein of 152 amino acid residues. A BLAST re-search using the deduced nucleotide sequences in HyH gene produced significant alignments with the H. perforatum. Sequences in HyH gene showed significant homology with Rubus idaeus putative allergen Rub-i-1 mRNA, Protein sequence comparisons revealed significant homology between Hyp-1 and the phenolic oxidative coupling protein hyp-1 of H. perforatum (98%). Additionally, Hyp-1 showed sig-nificant homology with various other classes of allergens, including Pru-av-1 (62%) from Prunus avium and allergen Bet-vl-Sc3 from Betula pendula (60%). Thus, the result of this study may offer an important information to establish an assay system for chemicals of the herbal medicines for H. erectum as well as H. perforatum.

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.

The identification of pork in commercially processed meats is one of the most crucial issues in the food industry because of religious food ethics, medical purposes, and intentional adulteration to decrease production cost. This study therefore aimed to develop a method for the detection of pork adulteration in meat products using primers specific for pig mitochondrial DNA. Mitochondrial DNA sequences for pig, cattle, chicken, and sheep were obtained from GenBank and aligned. The 294-bp mitochondrial DNA D-loop region was selected as the pig target DNA sequence and appropriate primers were designed using the MUSCLE program. To evaluate primer sensitivity, pork-beef-chicken mixtures were prepared as follows: i) 0% pork-50% beef-50% chicken, ii) 1% pork-49.5% beef-49.5% chicken, iii) 2% pork-49% beef-49% chicken, iv) 5% pork-47.5% beef-47.5% chicken, v) 10% pork-45% beef-45% chicken, and vi) 100% pork-0% beef-0% chicken. In addition, a total of 35 commercially packaged products, including patties, nuggets, meatballs, and sausages containing processed chicken, beef, or a mixture of various meats, were purchased from commercial markets. The primers developed in our study were able to detect as little as 1% pork in the heat treated pork-beef-chicken mixtures. Of the 35 processed products, three samples were pork positive despite being labeled as beef or chicken only or as a beef-chicken mix. These results indicate that the developed primers could be used to detect pork adulteration in various processed meat products for application in safeguarding religious food ethics, detecting allergens, and preventing food adulteration.

A comprehensive safety evaluation was conducted to assess the potential allergenicity of newly introduced proteins in genetically modified (GM) crops. We assessed the allergenicity of CP4 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) in GM soybeans. This assessment was performed by IgE immunoblotting with soy-allergic children's sera, amino acid sequence homology with known allergens, and the digestibility of CP4 EPSPS. No differences in IgE-antigen binding by immunoblotting were found between GM soy samples and the corresponding non-GM samples. Based on the comparison of EPSPS amino acid sequence homology with current allergen databases, no known allergen was found. In addition, CP4 EPSPS protein was rapidly digested by simulated gastric fluid (SGF). Taken together, these results indicate that GM soybeans have no allergenicity in children and are as safe as conventional soybeans.

Allergic rhinitis is an inflammation of the nasal mucosa which is triggered by an allergic reaction. When exposed to certain allergens, the IgE covered mast cells degranulate releasing inflammatory mediators and cytokines which results in a local inflammatory reaction. In many recent studies, molecular biological methods have been used to investigate the role of cytokines in pathogenesis and new therapeutic targets of allergic rhinitis. This experimental study was done to research effects of Sochungryong-tang. We have studied effect of mice on OVA-induced production of IL-4, IL-5, IFN-${\gamma}$ by murine splenocytes and effect of OVA-induced total IgE and OVA-specific IgE. The results were as follows; 1. In IL-4 study, Sochungryong-tang treated group was proved significant inhibitory effect(p〈0.005). 2. In IL-5 study, Sochungryong-tang treated group was proved significant inhibitory effect(p〈0.05). 3. In JFN-${\gamma}$ study, Sochungryong-tang treated group was proved significant inhibitory effect(p〈0.000001). 4. In Total IgE, Sochungryong-tang treated group was proved significant inhibitory effect(p〈0.000001). 5. In OVA-specific IgE, Sochungryong-tang treated group didn't showed significant inhibitory effect. Depending upon above results, it is considered that Sochungryong-tang has the inhibitory effect on the allergic rhinitis of mice and suggested that it could be used in relieving patients of the symptoms which are caused by allergic rhinitis.

Allergic Rhinitis (AR) is an IgE (immunoglobin-E) mediated inflammatory condition of upper respiratory tract; main clinical features involve runny nose, sneezing, nasal obstruction, itching and watery eyes. AR is a global problem and has large variations in incidences, currently affects up to 20% - 40% of the population worldwide. It may not be a life-threatening disease per se but indisposition from the condition can be severe and has the potential to adversely affect the daily functioning of life. Classical yoga literature indicates that, components of yoga have been used to treat numerous inflammatory conditions including upper respiratory tract. A few yoga intervention studies reported improvement in lung capacity, Nasal air flow and symptoms of allergic rhinitis. This review examined various anti-inflammatory pathways mediated through Yoga that include downregulation of pro-inflammatory cytokines and upregulation of anti-inflammatory cytokines. The hypothalaminic-pitutary-adrenal (HPA) axis and vagal efferent stimulation has been reported to mediate anti-inflammatory effect. A significant reduction is also reported in other inflammatory biomarkers like- TNF-alpha, nuclear factor kappa B (NF-κB), plasma CRP and Cortisol level. Neti, a yogic nasal cleansing technique, reported beneficial effect on AR by direct physical cleansing of thick mucus, allergens, and inflammatory mediator from nasal mucosa resulting in improved ciliary beat frequency. We do not find any study showing effect of yoga on neurogenic inflammation. In summary, Integrated Yoga Therapy may have beneficial effect in reducing symptoms and improving quality of life for patients with allergic rhinitis. Yoga may reduce inflammation through mediating neuro-endocrino-immunological network. Future studies are needed to explore the mechanism how yoga might modulate immune inflammation cascade and neurogenic inflammation at the cellular level in relevance to allergic rhinitis; the effects of kriyas (yogic cleansing techniques) also need to be evaluated in early and late phase of AR. So the proposed model could guide future research.

Purpose: In this study, we aimed to investigate the prevalence of year-round respiratory viral infection in children with lower respiratory tract infection (LRTI) and the relationship between respiratory viral infection and allergen sensitization in exacerbating asthma. Methods: We investigated the sources for acute LRTIs in children admitted to our hospital from May 2010 to April 2011. The 6 most common respiratory viruses were isolated from nasopharyngeal aspirate using multiplex reverse transcription-polymerase chain reaction in 309 children; respiratory syncytial virus (RSV), adenovirus (AV), parainfluenza virus (PIV), influenza virus (IFV), human metapneumovirus (hMPV), rhinovirus (RV). Atopic sensitization was defined if more than 1 serum specific Immunoglobulin E level measured using UniCAP (Pharmacia) was over 0.35 IU/mL. Results: RSV was the most common pathogen of bronchiolitis in hospitalized children through the year. RV or IFV infection was more prevalent in asthma exacerbations compared to other LRTIs. AV and hMPV were more likely to cause pneumonia. RV and IFV were associated with asthma exacerbations in children with atopic sensitization, but not in nonatopic children. Conclusion: RV and IFV are associated with hospitalization for asthma exacerbation in children with atopic sensitization.

Allergic disorders may be defined as the abnormal reactions to proteins. Cow milk is the first foreign protein which the human being would contact postnatally. Serveral studies suggested that this contact had certain effects on the development o allergic disorders with great controlversies. Seven hundred seventy eight students from middle class in Seoul, aged 6 to 17 wears, were surveyed to delineate the relationshpis between the cow's milk contacts in infancy and the subsequent development of allergic disorders in Koran population. Questionaire were included the nursing patterns in infancy, the past medical history of asthma or wheezy bronchitis and the presence of infantile eczema. Skin tests to three common resporatory allergens in Korea(house dust, house dust mite; D. farinae, D. ptoeronssinus) were performed. The positivity was determined by the wheal size larger than that to histamine. 70.2% of whole mateials was fed by breast milk, 13.1% by cow's milk and 16.7% by mixed nutsing. From the obsevation of nursing patterns by (table 2), we find that the number of breast milk group has been decreasing in 1970's. 10.1% of breast milk group(BMG) had wheezy bronchitis, 8.8% of cow's milk group(CMG) and 11.5% of mixed nursing group(MNG). Infantile eczema history was positive in 27.8% of BMG, in 26.5% of CMG and in 29% of MNG. Skin test positivity was 23.8% in BMG, 25.5% in CMG and 26.2% in MNG. There prevalences of allergic disorders in each nursing group did not reveal any statistically significant differences. In conclusion, nursing patterns in infancy do not seem to have certain effects on the development of allergic disorders such as infantile eczema. wheezv bronchitis or skin test positivity.

Objectives: SaengRyoSaMulTang is a herbal formula in Oriental Medicine, known anti-allergens. However, its mechanism and cellular targets have not been found yet. Thus the study has developed to investigate the suppressive effect of SaengRyoSaMulTang. Methods: In the study, cellular viability, IL-4, IL-13 mRNA expression, IL-4, IL-13 production, manifestations of GATA-1, GATA-2, NF-AT1, NF-AT2, AP-1 and NF-${\kappa}$B p65 transcription factors were examined by Real-Time PCR, ELISA analysis and western blotting. Results: As a result of treating with SaengRyoSaMulTang extract(SRSMT), the study has shown that the amount of Th2 cytokines, which include PI induced IL-4 and IL-13, plays a significant role in suppressing effect. RBL-2H3 mast cells significantly suppressed the PI-induced Th2 cytokine production including IL-4 and IL-13 in a dose dependent manner. PI-induced IL-4 and IL-13 production was significantly suppressed by SRSMT intervention. Western blot analysis of transcription factors involving IL-4 and IL-13 expression also revealed a prominent decreases of mast cell's specific transcription factors including GATA-1, GATA-2, NF-AT2, c-Jun and c-Fos, but NF-${\kappa}$B p65. Conclusions: The study suggests that the anti-allergenic activities of SRSMT may regulate the transcription factors GATA-1, GATA-2, NF-AT2, c-Jun and c-Fos inhibiting Th2 cytokines IL-4 and IL-13 in mast cells.
