Prevalence of asthma is increasing in westernized countries. Epidemiological studies
showed the impact of traffic pollution on the triggering of asthma symptoms and …

Ammonium persulfate (AP) causes occupational asthma (OA) and diesel exhaust particles
(DEP) exacerbate asthma; however, the role of DEP in asthma due to chemical agents has …

Background: An epidemiologic relationship between airway allergic diseases and exposure
to atmospheric pollutants has been demonstrated and suggested to be one factor in the …

Epidemiological studies have shown that high particulate air pollution is associated with an
increase in hospital admissions for respiratory diseases and with an exacerbation of asthma …

There is growing evidence that diesel exhaust particles (DEP) can induce allergic diseases
with increased IgE production and preferential activation of Th2 cells. To clarify the cellular …

BACKGROUND: Epidemiologic studies show that exposure to ambient particulate matter
leads to asthma exacerbation. Diesel exhaust particles (DEPs), a model pollutant, act as an …

Background: Epidemiologic and experimental studies suggest that air pollution such as
diesel exhaust particles (DEPs), one of the important air pollutants, may play a role in the …

Host responses to DEPs are regulated by a balance between antioxidants and
proinflammatory responses. DEP-induced oxidants play a key role in proinflammatory …

BACKGROUND: Epidemiologic studies show that sudden surges in ambient particulate
matter (PM) levels can trigger acute asthma exacerbations. Although diesel exhaust …

There is good evidence that urban air pollutants, and particularly diesel exhaust particles
(DP), contribute to the increasing prevalence of asthma and allergic rhinitis. Diesel exhaust …
