Abstract:
Objective To explore the relationship between the concentrations of dust mite allergen and lipopolysaccharide (LPS) in the working place and home for the workers. Methods 30 workers were selected as the experimental group in June, 2005, divided into A and B groups, 15 workers of flour processing in A and 15 workers of leather processing in B respectively, at the same season, 20 teachers from a college were selected as the control group (C group). 360 dust specimen were collected, the concentrations of allergen Der p1, Der f1 were determined by ELISA and the LPS concentration were determined by a kinetic Limulus assay. Results Concentration of allergen Der p1 and Der f1 (median:335.1 and 118.8, 350.0 and 174.1, 31.1and 3.4, 81.5 and 9.6 ?g/g in different sites respectively) in A group was the highest, LPS in B group was the highest (median: 234, 268, 104, 54 EU/mg in different sites respectively). The concentration of allergen in the suspending dust was correlated with those in mattress and floor dust (rs=0.661, P
