The season of symptom appearance ...
Each spring millions of patients suffer from allergies when birch pollen is released into the air. In most cases, the major pollen allergen Bet v 1 is the elicitor of the allergy symptoms. Bet v 1 comes in a variety of isoforms that share virtually identical conformations, but their relative concentrations are plant-specific. Glycosylated flavonoids, such as quercetin-3-O-sophoroside, are the p...
BACKGROUND Dolichandrone platycalyx, commonly known as Nile trumpet tree, is believed to have originated in East Africa. However, this and the variants of this tree are found in Europe, Asia, and America (California and Florida). The tree mostly grows in tropical climates, but temperate species are also found. This study was designed to evaluate the allergenicity of D. platycalyx, one of the mo...
Plant allergies are a frequent cause of visits to the allergologist. In the Alergologica 2005 study carried out in Spain, fruits were the main cause of food allergies [1]. Plant allergies in a specific population are related to consumption habits and to the pollen pattern of the region under study. The objective of this retrospective study was to determine the proteins responsible for fruit all...
BACKGROUND Pollen released by allergenic members of the botanically unrelated families of Asteraceae and Cupressaceae represent potent elicitors of respiratory allergies in regions where these plants are present. As main allergen sources the Asteraceae species ragweed and mugwort, as well as the Cupressaceae species, cypress, mountain cedar, and Japanese cedar have been identified. The major al...
Depending on the geographic and climatic region and vegetation, allergenic plants are characteristic for certain areas and the pollen concentrations of various plant species depend on the fenophase of each single species and most of all on the climatic and meteorological conditions of a certain area. It is precisely because of these specific characteristics that the hypersensitivity of patients...
Introduction Sunflower seed is one of the most commonly consumed snacks in our country. Sunflower seeds are not only eaten as snacks but also are used as ingredients of breads, mueslies and bars in recent years. Sunflower seed allergy is seen rarely in children and may be presented as angioedema or anaphylaxis. Respiratory allergies have been reported previously in adults owning birds fed on su...
Introduction The immune system, which is the self-defense system of the body, occasionally responds in a manner that is harmful to the body. The incidence and severity of allergies caused by cedar pollen, house dust, egg protein, and many others are increasing and have recently become a serious social problem. We have previously developed an original in vitro system for inducing human IgE antib...
Background Ingredients of aloe vera leaves are being increasingly used for their anti-inflammatory and slimming properties. However, serious allergic reactions are very rare and only occasionally reported. Here, we present an eleven year old girl with anaphylaxis within minutes after topical administration of aloe vera to a skin lesion. On admission, the girl showed no signs of respiratory or c...
