During past few years, the Cupressus arizonica has been abundantly planted in Tehran, causing a significant increase of allergic diseases from the middle of winter to the beginning of spring. The aim of this study was the comparison of pollen protein content in two major varieties of C. arizonica planted in Tehran, including C. arizonica var. arizonica and C. arizonica var. glabra, in order to ...

three different concentrations (10, 20 and 30 ppm) of the dry propolis and pollen extracts were applied in double distilled water. biochemical and hematological parameters in blood of rainbow trout (oncorhynchus mykiss) treated to various propolis and pollen concentrations (10, 20 and 30 ppm) for 96 h were determined.  fish treated to 20 and 30 ppm of propolis extract presented significant incr...

Lolium multiflorum (Lm) grass pollen is the major cause of pollinosis in Southern Brazil. The objectives of this study were to investigate immunodominant components of Lm pollen allergens and the cross-reactivity of IgE with commercial grass pollen allergen extracts. Thirty-eight serum samples from patients with seasonal allergic rhinitis (SAR), 35 serum samples from patients with perennial all...

BACKGROUND Allergen extracts may be different due to the difference in dissemination of allergen-containing species in various geographical areas. Therefore, we wish to develop our own extracts to ensure the precision and quality of diagnosis. OBJECTIVES To compare the efficacy and safety of our locally prepared pollen allergen extracts to imported ones, using skin prick testing (SPT) and ser...

BACKGROUND Wild plants harbour a variety of viruses and these have the potential to alter the composition of pollen. The potential consequences of virus infection of grasses on pollen-induced allergic disease are not known. METHODS We have collected pollen from Dactylis glomerata (cocksfoot; a grass species implicated as a trigger of allergic rhino-conjunctivitis) from Wytham Wood, Oxfordshir...

This study was designed to determine the level of satisfaction, tolerance and perceived effectiveness by patients in the first pollen season after starting treatment with Alergovit(®). For this purpose, a nationwide, retrospective, multicentre and cross-sectional observational study was carried on 256 patients. Perceived effectiveness by the patients was measured using a visual analogue scale a...

BACKGROUND Airborne Plantago pollen triggers respiratory allergies in Mediterranean countries. OBJECTIVES We aimed to study sensitization in patients with seasonal respiratory allergy and identify proteins of Plantago lanceolata pollen that could be responsible for hypersensitivity reactions in sensitized patients. We also determined the airborne pollen concentration of Plantago species from ...

Apicultural products l ike propolis and pollen have gained increased attention for their therapeutic properties. The aim of this study was to assess antibacterial properties of Egyptian propolis and pollen extracts or their mixtures which were extracted by different ethanol/water concentrations against 6 food borne pathogenic, as well as 4 lac tic acid bacterial (LAB) strains. Antibacterial ac ...

BACKGROUND Current diagnostics for allergies, such as skin prick and radioallergosorbent tests, do not allow for inexpensive, high-throughput screening of patients. Additionally, extracts used in these methods are made from washed pollen that lacks pollen surface materials that may contain allergens. METHODOLOGY/PRINCIPAL FINDINGS We sought to develop a high-throughput assay to rapidly measur...

Pooideae species. While for several species the most important allergens (group 1 and group 5) have been identified, other allergens have either not been identified or sequence data are still missing. We have used mass spectrometry (MS) together with genetic and immunological methods to identify allergens in various grass pollen extracts. Methods: Pollen extracts of 6 different grass species (P...
