Allergic reactions begin from the reaction of an antigen and IgE on the membrane surface of basophils and mast cells. The chemical mediators are released from the cells activated by the reaction of antigen and IgE. The chemical mediators proceed to the reactions of focal or total body inflammation. Measurements of serum IgE, chemical mediators, and cytokines are important parameters for the diagnosis and therapy of allergic disease. Antigen analyses are possible by application of EIA. It is also possible to apply EIA in the prevention of allergic diseases.

Three bands stained with Coomassie Brilliant Blue R were detected on SDS-PAGE. Sera from 27 (55.1%) out of the 49 children showed positive reaction to the pollen extract in ELISA. The same sera from the 27 children were used as the first antibody in immunoblotting, which confirmed the presence of a band of protein with 70 K dalton molecular weight (M.W) common to the all sera. This band was bound with concanavalin A in lectins. We successfully purified the antigenic substance of Japanese juniper pollen from this band by the electroelution method. The major allergen of Japanese juniper pollen is glycoprotein with 70 KM.W. On sandwich-ELISA, there was no reaction of Sugi Basic Protein (SBP) and anti-SBP to Japanese juniper is an allergen that has no cross-reactivity with SBP.

Of these, estrogen has been the subject of much study. This review highlights recent research exploring the effects of estrogen in allergic disease. Recent findings-Estrogen receptors are found on numerous immunoregulatory cells and estrogen's actions skew immune responses toward allergy. It may act directly to create deleterious effects in asthma, or indirectly via modulation of various pathways including secretory leukoprotease inhibitor, transient receptor potential vanilloid type 1 ion channel and nitric oxide production to exert effects on lung mechanics and inflammation. Not only do endogenous estrogens appear to play a role, but environmental estrogens have also been implicated. Environmental estrogens (xenoestrogens) including bisphenol A and phthalates enhance allergic sensitization in animal models and may enhance development of atopic disorders like asthma in humans. Summary-Estrogen's role in allergic disease remains complex. As allergic diseases continue to increase in prevalence and affect women disproportionately, gaining a fuller understanding of its effects in these disorders will be essential. Of particular importance may be effects of xenoestrogens on allergic disease.

The most common treatment for seasonal allergic responses is the daily use of oral antihistamines, which can control some of the symptoms, but are not effective for nasal congestion, and can be debilitating in many patients. Peptide immunotherapy is a promising new approach to treat allergic airways diseases. The small size of the immunogens cannot lead to an unwanted allergic reaction in sensitized patients, and the production of peptides with sufficient amounts for immunotherapy is time- and cost-effective. However, it is not known what peptides are the most effective for an immunotherapy of allergens. We previously produced a unique monoclonal antibody (mAb) E58, which can inhibit the binding of multiple groups of mAbs and human IgEs from patients affected by the major group 1 allergens of ragweed (Amb a 1) and conifer pollens (Jun a 1, Cup s 1, and Cry j 1). Here, we demonstrated that a combined approach, starting from two linear E58 epitopes of the tree pollen allergen Jun a 1 and the ragweed pollen allergen Amb a 1, and residue modifications suggested by molecular docking calculations and peptide design could identify a large number of high affinity binding peptides. We propose that this combined experimental and computational approach by structural analysis of linear IgE epitopes and peptide design, can lead to potential new candidates for peptide immunotherapy.

Pollen of different species of the Taxodiaceae family (Cryptomeria japonica, Sequoia sempervirens and Metasequoia glyptostroboides) and Japanese juniper (Juniperus rig&) in the Cupressaceae family, which are propagated mainly in the southern region of Okayama Prefecture, were found among the atmospheric pollen. Scratch tests using the pollen extract from Taxodiaceae and Cupressaceae were performed on children with bronchial asthma. Forty (25%) and 30 (18.8%) of the 160 patients reacted positively to an allergen extract from the pollen grains of Japanese cedar (Cryptomeuia japonica) and Japanese juniper, respectively.

Design: Prospective, clinical trial. Setting: Operative theater of a university hospital. Patients: 95 adult patients. Interventions: Patients were preoperatively screened and classified for present latex allergy (high-risk and low-risk group) according to a specially designed screening questionnaire. Anesthesia and surgery in the high-risk group were performed strictly avoiding latexcontaining materials. The low-risk group (other allergies including pollinosis) received routine treatment, without latex-avoidance. Effects of latex avoidance or exposure were evaluated by measuring specific IgE titers perioperatively. Measurements and Main Results: According to the questionnaire, 45 patients at high risk were defined. Validity of classification of high-risk patients is supported by significantly higher total IgE and latex and grass profilin specific IgE compared to the low-risk group. There were no significant differences in other profilin-specific IgEs. In one case of severe anaphylactic reaction a drop of latex-specific IgE during surgery could be observed. Conclusion: The questionnaire allowed the identification of most patients at high risk for latex allergy. In isolated pollinosis no changes in any specific IgE levels were detectable. Strict avoidance of perioperative latex exposure in high-risk patients increases safety during anesthesia and surgery.

This study confirms that the number of live mites recovered from carpets by vacuum cleaning is low. However, most central Florida homes have total mite numbers above the proposed thresholds to cause sensitization and/or symptoms. Mite numbers are positively associated with home and carpet age and negatively with the presence of pets in homes.
