[The dispersion and allergenicity of the airborne pollen in Nanjing].

This paper presents the results of a two-year study on the dispersion and allergenicity of the airborne pollen in Nanjing. We found 28 families of pollen of plant dispersing in the city. Seventeen species of commonly seen pollen grouped under twelve families were collected and their pollen extracts were used for skin test in the 219 cases of bronchial asthma. The results showed the mode of dispersion of air-borne pollen and the main families of allergic pollen being the Moraceae' Cupressaceae platanuceae and Julandaceae in spring and the gramineae Compositae Chenopodiaceae and Cannabinaceae in autumn. This information provides a firm basis in the prevention diagnosis and treatment of allergic diseases in the area of Nanjing.
