background: diagnosis of food allergy is difficult in children. food allergies are diagnosed using several methods that include medical histories, clinical examinations, skin prick and serum-specific immunoglobulin e (ige) tests, radio-allergosorbent test (rast), food challenge, and supervised elimination diets. in this study we evaluated allergies to cow's milk, egg, peanut, and fish in c...

in recent decades, biotechnologists have striven to improve the quantity and quality of food supply. producing genetically modified (gm) foods is one of the main goals and many countries all over the world have approved the distribution and consumption of the labeled gm foods in their own regions. however, there are still few groups having concerns about allergenicity of gm foods. this review h...

Hypersensitivity pneumonitis (HP) is an inflammatory disease of the lungs and airways that develops in response to repeated inhalation a wide range aerosol antigens. The clinical picture course HP are highly variable depend on such factors as nature antigen, intensity duration exposure well characteristics patient's immune response. annual incidence HAP 1.28 -1.94 cases per 100 000. Currently, ...

Hypersensitivity reaction is an adverse immune response to antigen. It also called as Intolerance. There are 4types of hypersentivity. In this case report we will be discussing about hypersensitivity developed after the bite a Red ant in 10years old boy. He had been treated with Apis mellifica 200 potency based on symptoms similarity. This evidenced that when homoeopathy prescribed basis sympto...

the study aimed to assess the prevalence and associated risk factors of immediate-type hypersensitivity reactions (hrs) to drugs in workers. the data consisted of 1152 questionnaires obtained from adult men that consisted of questions on hrs induced by drugs. the prevalence of self-reported drug hrs was 3.6% for all reactions. hrs were most common to beta-lactam antibiotics (51.2%) followed by ...

beta-lactams are a group of antibiotics with a broad spectrum of both gram-negative and gram-positive coverage. the goal of this study is to evaluate the results from studies regarding ig-e mediated hypersensitivity to penicillin and cross-reactivity with other beta-lactams. review was conducted of both retrospective and prospective studies by searching in pubmed and medline for the original an...

background and aims . the aim of this study was to evaluate the clinical desensitizing effects of potassium nitrate and strontium acetate in reduction of hypersensitivity. materials and methods . thirty eight patients who presented dental hypersensitivity were selected and randomly allo-cated into two groups. group i: patients who were treated by potassium nitrate 5% foam, and group ii: patient...

contact hypersensitivity (chs) mouse model induced by 2, 4-dinitrofluorobenzene (dnfb) is thought to be a t helper 1 (th1)-dominant response and used for investigating anti-inflammatory and immunosuppressive agents. however, it is hardly used for screening large-scale drugs because of the large number of animals and complex mechanisms involved in-vivo. in this study, we focused on whether t lym...

in this study, we investigate the immunostimulatory effects of alcoholic extract of the coffee seed on cell-mediated immune response andcyclophosphamide-induced (cp) immunosuppressed mice. the assessment of cellular immune function was carried out by the measurement of delayed-type hypersensitivity (dth) response. according to the literature survey, cyclophosphamide has only suppressing effect ...
