Peanut and buckwheat induce a severe allergic reaction, anaphylaxis, which is considered to be mediated by immunoglobulin E (IgE). We identified in this study a new IgE-binding epitope of the peanut allergen that cross-reacted with buckwheat. The phosphate-buffered saline-soluble fraction of buckwheat inhibited the binding between IgE and the peanut allergen. A cross-reactive peptide was isolat...

To prove the existence of possible allergic reaction to local anaesthetic by the recommendations and experience of the current literature, an assortment or mosaic of complementary diagnostic tests is made by: anamnesis and a clinical picture and in vivo skin allergy tests - tests of the humeral and cellular immune response. Anamnesis and the clinical picture are mostly in metaphorical character...

BACKGROUND Corticosteroids (CS) are widely used in the treatment of asthma, allergic disorders and other immunological diseases due to their anti-inflammatory and immunosuppressive properties. Physicians seldom suspect them of causing allergic reactions. However, more and more cases of hypersensitivity reactions to CS have been described. Reports of delayed allergic reactions to CS in patients ...

One of the most important adverse consequences of patch testing is active sensitization, when subjects previously not allergic become sensitized to one or more of the test chemicals by the test procedure. The allergic test reaction then shows up about 10 or more days (late reaction) after the test application. Sometimes, however, late reactions are seen without active sensitization being presen...

Rabbits presumably sensitized to components of the streptococcal cell by natural contact with cross-reactive microbial antigens in their environment, display distinctive phases of evolving allergic response to an extract of streptococcal cells. Animals under 4 weeks of age show no gross allergic skin reaction; this is followed successively by age periods in which allergic reactions become most ...

We studied the allergic reaction of guinea pigs to glyceryl methacrylate (GM), hydroxyethyl methacrylate (HEMA) and meso-erythritol methacrylate (EM), which are used as dentin primers. On the 18th day of the application test, when macroscopic investigation revealed an inflammatory reaction, the methacrylic acid-treated group showed marked eschar formation in comparison with the control group. I...
