the pathogenetic mechanism of nasal polyps remains unknown, although allergy has been cited as an important factor in the etiology of nasal polyposis. currently there is no definite histological criterion for differentiation of allergic from inflammatory nasal polyp. however, in a few studies, tissue eosinophil count has been used for this. this study aimed to find out the agreement rate of ski...

allergic rhinitis is the most common cause of allergic diseases. the recent guidelines of allergic rhinitis and its impact on asthma (aria) group, classified it to intermittent (less than 4 days per week and for less than 4 weeks) and persistent (more than 4 days per week or lasting more than 4 weeks regardless of the number of days per week). the present study evaluates the patients with aria ...

results: a total number of 117 patients were evaluated for adverse drug reactions, among them, 97 (82.9%) were considered to have immunological drug reactions. the most common symptoms of allergic drug reactions were morbilliform eruptions, serum sickness, dress (drug rash with eosinophilia and systemic symptoms), and toxic epidermal necrolysis. in 62 patients, anticonvulsant drugs had the prom...

Background & Objective: Allergies are manifested with a variety of signs and symptoms. In this study, the frequencies of asthma symptoms, allergic rhinitis, eczema, and related factors among 6- to 7-year-old schoolchildren were investigated. Materials & Methods: This cross-sectional study was carried out among schoolchildren of 35 elementary schools of Zanjan by using the International Study o...

interleukin (il)-25, a cytokine of il-17 family, can activate p38 mitogen-activated protein kinases(mapk) and nuclear factor(nf)-κb pathways to propagate th2 responses. the allergic rhinitis mouse model was established by stimulating balb/c mouse with ovalbumin (ova). then we detected expression of il-25 and downstream p38mapk and nf-κb. the expression of il-25, p38mapk and nf-κb were detected ...

Background: The prevalence of allergic diseases is increasing worldwide. The effective role of omega-3 fatty acids in the maturation of immune system and protection against atopic diseases has been well discussed. However, previous studies revealed conflicting results. This study was conducted to investigate the effect of fish oil consumption by nursing atopic mothers on the level of interferon...

BACKGROUND There is considerable concern about the rising trend in the prevalence of asthma and allergic diseases. The ability to monitor this trend would be enhanced by the use of a biological marker for these diseases. OBJECTIVE This study investigated whether serum interleukin (IL) 12 and IL-18 levels were associated with allergic symptoms such as those of asthma, allergic rhinitis, and at...

allergic diseases are frequent in children and their prevalence and severity deffer in the different regions of the world. a number of studies have been performed to determine the factors which are effective in the incidence of these diseases. one of the drugs that might have a role in incidence or intensity of the symptoms of allergic diseases is acetaminophen. in our survey conducted with sta...

Recent studies of several animal models have shown beneficial effects of probiotics against allergic responses. However, few reports have examined the effects of probiotics on allergic nasal symptoms such as sneezing and nasal obstruction in animal models of allergic rhinitis. This study evaluated the efficacy of Bifidobacterium bifidum G9-1 (BBG9-1) on antigen-induced nasal symptoms using guin...
