Funds collection zebranie funduszy SummaryBackground. The aim of this work was to find out which of the aeroallergens most often cause positive skin prick tests in the population with allergic diseases. Depending on the type of allergens, exposure to them can aggravate asthma symptoms and cause allergic conjunctivitis and allergic rhinitis. Material and methods. A group of 100 people between 18 and 78 years of age were included in the study. The average age was 45.8 years. There were 34 men and 66 women in the group. All patients were allergy clinic patients. The results of point skin tests for the basic aeroallergen panel were analyzed in this study and summarized using descriptive statistics. Results. Sixty subjects had positive tests for dust mites. Most subjects were allergic to two allergens. Monovalent allergy was found in 10 subjects. Multivalent allergy was predominant, but tended to involve relatively few allergens. Conclusions. The results obtained may be due to year-round exposure to the house dust mite allergen. Prolonged allergen exposure translates into more frequent immune responses and greater clinical response of patients, which is manifested by allergic rhinitis and/or bronchial asthma or allergic conjunctivitis. Due to the small patient population studied, this subject requires further analysis.

A clear distinction between the morphology of allergenic pollen grains of various genera of the Poaceae family is an important task in determining the causal allergenic factors in the population. It allows significant improvement of the efficiency of seasonal allergy diagnostics caused by grass pollen. Moreover, it let to perform better predictions of allergenic risks for people, suffering from pollinosis caused by Poaceae pollen. Therefore, the aim of our study was to establish the morphological difference between the pollen grains of plants of various species of Poaceae family in order to further determination of the possibility to use the established distinctions for the identification of pollen in aerobiological studies. For this, both herbarium samples and pollen of the studied plants were collected in the field during May-June 2019 in Vinnytsia. The pollen was shaken off the anthers directly onto a glass slide, immediately stained with basic fuchsin, and covered with a cover slip. The sizes of pollen grains – their width and length – were determined and analyzed using the PhotoM 1.21 program, and the obtained data on the sizes of pollen were divided into categories by the quartile method in Excel. Three categories of pollen sizes were identified: large, medium and small. Large grains had width and length parameters of 40 μm or more, average grains ranged from 26 to 39 μm, and small grains had a size of 26 μm or lesser in width and length. The large category includes the pollen of Hordeum morinum (39.5-53.1 μm), Elytrigia repens (41-48 μm), Secale cereale (48.4-62.5 μm) and Bromus arvensis (42.2-52.7 μm). The medium grain category included pollen from Dactylis glomerata (29.2-38.1 μm), Poa spp. (26.1-37.3 μm), Panicum capillare (33.3-39.5 μm), Lolium perenne (30.4-35.3 μm), Bromus sterilis (28.3-30.8 μm). The pollen size of B. ramosus ranged from 26.1 to 39.5 µm, and B. tectorum was from 35 to 38.4 µm. The pollen grains of Poa pratense (22.1-25.9 μm) and Piptatherum spp were assigned to the category of the smallest pollen (20.3-24.1 microns). Agrostis gigantea was the only grass pollen type whose size fitted for each category. We found out large, medium-sized and grains of 25.0-27.7 microns, which lie between categories 2 and 3, for different populations of this plant. Consequently, some genera and species of Poaceae can be distinguished by the size of their pollen, while in others the size of pollen grains varies considerably. It is necessary to carry out further research that will help to establish the morphology of pollen of a larger number of Grass family plants. This will significantly improve the diagnosis and prevention of seasonal allergy caused by grass pollen in Ukraine.

Introduction: Allergic sensitization to aeroallergen (atmospheric pollen and fungal spores) is the most common seasonal allergy trigger. The main reason for that study is unexpected skin prick test results obtained in our dermatology department. For that reason, we would like to check whether the consequences depend on cross-reactivity or aeroallergen invasion. Aim: The purpose of the present study is to determine the pollen types, including the amount and concentration of the native and invasive pollen in the Çanakkale Region during the spring and summer periods. The main reason for that study is unexpected skin prick test results obtained in our dermatology department. For that reason, we would like to check whether the consequences depend on cross-reactivity or aeroallergen invasion. Material and methods: The pollen monitoring station was placed in the Çanakkale Central Public Park. The sampling was performed by a Durham trap based on the gravimetric method. The slide was replaced with a new one every week and evaluated by 10× ocular and 40× apochromatic lenses. Results: The primary pollen producers were the following arboreal plants: Pinus sp. (65.0%), Quercus sp. (9.37%), Platanus sp. (4.29%), Moraceae (3.87%), Oleaceae (2.71%). The pollen distribution of herbaceous plants and bushes were determined as Poaceae (4.34%), Chenopodiaceae (1.99%), Plantago sp. (1.97%) and Xanthium sp. (1.35%). In addition to our current knowledge, Ambrosia pollens' first record was found with a ratio of 0.22% in the Çanakkale atmosphere. These invasive plants have most probably entered the atmosphere with long-distance transport. Conclusions: Aerobiological monitoring is essential to determine allergen variety and concentrations to find a cure against pollinosis. The health professionals should apply a skin prick test against a significant allergen, i.e. Ambrosia pollens even if there is no previous report in the region. The authors also advised clinicians to be aware of pollen invasion to ensure that patients do not have false-negative results.
