INTRODUCTION Maize and rice are two crops constituting the main food supply in many under-developed and developing countries. Despite the large area devoted to the culture, the sensitization to the pollen from these plants is reported to be low and often considered as an occupational allergy. METHODS Sixty five Malagasy pollen allergic patients were clinically and immunochemically investigate...

Background: Alongside hazel, alder and birch pollen allergies, ash pollen allergy is a relevant cause of hay fever during spring in the European region. For some considerable time, ash pollen allergy was not routinely investigated and its clinical relevance may well have been underestimated, particularly since ash and birch tree pollination times are largely the same. Ash pollen extracts are no...

BACKGROUND Pollen grains have been reported to be present in the Philippine atmosphere but studies regarding their allergenicity are limited. OBJECTIVE The present study aimed to profile the sensitization of allergic individuals to selected grass pollen species and to characterize the pollen proteins that may be responsible for this allergenic response. METHODS The protein profile of the gr...

Grass pollen is one of the most important vectors of aeroallergens. Under atmospheric conditions, pollen grains can release pollen cytoplasmic granules (PCGs). The allergens associated with these intrinsic subfractions induce, in laboratory animals as well as in asthmatic patients, allergic and inflammatory responses. The objectives of this study were to characterize the PCGs' intrinsic allerge...

The effect of Persian bee propolis and pollen extracts on innate immune response of rainbow trout (Onchorhynchus mykiss) was investigated. Fish were fed diets containing 1% Pollen, 1% propolis and combination of the two immune-stimulants (0.5% Pollen and 0.5% propolis) as treatment groups and fed without the two immune-stimulants as positive and negative control groups for 4 weeks. The effects ...

BACKGROUND Grass pollen allergens are a major cause of allergic respiratory disease but traditionally prescribing practice for grass pollen allergen-specific immunotherapy has favoured pollen extracts of temperate grasses. Here we aim to compare allergy to subtropical and temperate grass pollens in patients with allergic rhinitis from a subtropical region of Australia. METHODS Sensitization t...

Methods and results: fifty-seven (57) patients with a well-documented history of seasonal grass pollen allergy were evaluated in a DBPC trial over a period of 10 months (January to November 1995) with a view to investigating the efficacy and safety of sublingual immunotherapy with a grass pollen extract, 9,500 BU/ml. The course of treatment consisted of an incremental phase of approximately 3 w...

Pollen grains can play an important role in allergic diseases and many studies have revealed that allergenicity increases in industrial cities. In Bushehr province in Iran Avicennia marina (Forsk.) Vierh. has grown in two regions, Bordekhoon (Mond protected Area) and Assaluyeh (Marine National Park of Nayband). Assaluyeh (polluted area) is an industrial region with petrochemical factories that ...

BACKGROUND There is limited data regarding pollen food allergy syndrome (PFAS) in Turkey. OBJECTIVES To investigate the clinical characteristics and possible risk factors of PFAS in Turkey, and to evaluate if there was an association between skin test reactivity to pollens and presence of PFAS. METHODS A total of 254 consecutive adult patients with pollen sensitivity were prospectively recr...
