Abstract:
The pollen calendar of Agra
was recorded with special reference to allergenic significance. Pollen grains
of 35 species belonging to 23 angiosperm families have been identified out of a
total catch of 24,220/m3 of air annually. High occurrence of pollen
grains in air belonged to Asteraceae (5222/m3)
and Parthenium hysterophorus
contributed the maximum (17.91%) of the total airspora.
Higher counts of pollen were found in ecozones
surrounded by agricultural fields, parks and gardens. The skin prick tests for
the clinical investigation were made. Patients of bronchial asthma with
rhinitis (62.30%) were maximum followed by bronchial
asthma (25.61%) and allergic rhinitis (12.07%). Maximum number of patients had
symptoms between the age group of 31-40 years and male were more sensitive than
females. Maximum sensitivity was caused by Amaranthus
spinosus, followed by P. arthenium,
P. hysterophorus, Chenopodium
album, Cynodon dactylon and
Cassia occidentalis.
Key
