background: there are many therapeutic methods for allergic conditions. cpg oli-gonucleotides play a critical role in immunity via the augmentation of th1 and suppres-sion of th2 responses. objective: in the present study we aimed to estimate the effec-tiveness of intranasal administration of cpg odn plus chenopodium album allergen in allergic asthma compared with the administration of allergen...

We have previously shown that unilateral nasal challenge with antigen causes an increase in the number of eosinophils in the ipsilateral maxillary sinus. Here we aimed to determine whether there was an eosinophil response in the contralateral maxillary sinus after unilateral nasal challenge with antigen. Twenty subjects with a history of seasonal allergic rhinitis and a positive nasal challenge...

BACKGROUND S100A7 is an antimicrobial peptide involved in several inflammatory diseases. The aim of the present study was to explore the expression and regulation of S100A7 in seasonal allergic rhinitis (SAR). METHODS Nasal lavage (NAL) fluid was obtained from healthy controls before and after lipopolysaccharide (LPS) provocation, from SAR patients before and after allergen challenge, and fro...

BACKGROUND Natural rubber latex (NRL) allergy in workers using rubber gloves has been an occupational health problem for the last 10 years. In the case of the occupational agents, clinical history may be far from conclusive; hence, appropriate provocation should be carried out. The objective was to evaluate the usefulness of the nasal challenge test in the diagnosis of allergic rhinitis in subj...

BACKGROUND No large studies in adults has examined geographical variation in the prevalence of nasal allergy/allergic rhinitis in adults or considered the proportion of reported nasal symptoms on exposure to allergen attributable to atopy. The aim of this report was to describe the geographic distribution of subjects with nasal symptoms who are sensitized as determined by skin prick tests, usin...

OBJECTIVE 1) To estimate the effectiveness of intranasal administration of CpG DNA alone on allergic rhinitis compared with intradermal administration; and 2) to find out how CpG DNA therapy is useful in treatment of allergic rhinitis. STUDY DESIGN Mice were intraperitoneally sensitized and intranasally challenged with Japanese cedar. Therapy with CpG DNA alone was also performed during chall...

Background Optimizing methods for the study of allergic rhinitis (AR), especially when using samples likely containing small amounts of material for analysis, ensures the integrity of results that may potentially enhance the understanding of AR disease mechanisms. In order to conduct future mRNA expression analysis, examining the differential expression of AR mediators such as IL33, TSLPR, HPGD...
