Grass pollen allergens are a frequent cause of pollen allergy in Poland and other European countries. The research on aeroplankton conducted in Lublin since 2001 allows characterization of the course of grass pollen seasons and estimation of the effect of maximum and minimum temperatures, relative air humidity, precipitation and maximum wind velocity on the taxon’s pollen concentration. The gravimetric method was used in the study. During the eight-year research period, the pollen season usually started in the first or second decade of May and, as a rule, it lasted till the end of August, and quite exceptionally, in 2002 and 2008 till mid-August. The mean length of the pollen season was 107 days. The highest grass pollen risk was observed in the 26th and 27th week. The highest annual counts reaching over 3600 pollen grains􀂉 cm-2 were noted in 2008, while in the other study years they ranged from 741 to 1909. The date of the pollen season onset and its course were highly dependent on weather conditions, which was confirmed by the statistical analysis. The greatest significant influence on the pollen season was exerted by maximum temperature, relative air humidity and the maximum wind.
The purpose of this study was to assess the positive immediate reactions received from intradermal skin tests (IDST) which confirmed the presence of IgE-dependent hypersensitivity in dogs with atopic dermatitis, which were patients of the Dermatology Consulting Section at the University of Life Sciences in Lublin between 2007 and 2009. Intradermal skin tests were performed on 142 dogs (72 females and 70 males) from the Lublin voivodeship of different breeds ranging in age from 1 to 6 years (average 2.8 years). The allergen set used in this study was the Artuvetrin Test (ARTU Biologicals Europe B.V, Holland). The owners of 84 dogs observed the presence of skin lesions all year round regardless of season, while 58 dog owners noted them only in spring and summer. Most immediate positive reactions were ascertained from mite allergens (70.61%), fewer from pollen allergens (19.55%), and the fewest from animal (4.15%) and mould allergens (1.66%). Immediate positive reactions for a flea allergen (4.03% of all positive reactions) were also ascertained. In 98.6% of dogs polysensitization was found.
