Pollen allergies in czechoslovakia

The article discusses the possible utilisation of the palynological and geobotanical observations in immunotherapy of children with pollinosis in Czechoslovakia. Three approaches to this problem exist: 1. Use of the individual pollen mixtures (prepared by the Institute of Sera and Vaccines (USOL), Prague), according to the clinical history and the results of diagnostic tests of each patient. 2. Use of the available standard pollen mixtures. 3. Improvement of the specificity of these mixtures by eliminating the redundant pollen types (i.e. pollen of the species not spread in the area). Intentions for the future, including the establishment of a pollen forecasting service, are mentioned.
