Nociceptive mechanisms modulate ozone-induced human lung function decrements.
We have previously suggested that ozone (O3)-induced pain-related symptoms and inhibition of maximal inspiration are due to stimulation of airway C fibers (M. J. Hazucha, D. V. Bates, and P. A. Bromberg. J. Appl. Physiol. 67: 1535-1541, 1989). If this were so, pain suppression or inhibition by opioid-receptor agonists should partially or fully reverse O3-induced symptomatic and lung functional ...
متن کاملDiesel exhaust exposure enhances the ozone-induced airway inflammation in healthy humans.
Exposure to particulate matter and ozone cause adverse airway reactions. Individual pollutant effects are often addressed separately, despite coexisting in ambient air. The present investigation was performed to study the effects of sequential exposures to diesel exhaust (DE) and ozone on airway inflammation in human subjects. Healthy subjects underwent bronchoscopy with bronchoalveolar lavage ...
متن کاملLong-term exposure to diesel engine exhaust induced lung function decline in a cross sectional study
To clarify the effects of lung function following exposure to diesel engine exhaust (DEE), we recruited 137 diesel engine testing workers exposed to DEE and 127 non-DEE-exposed workers as study subjects. We performed lung function tests and measured cytokinesis-block micronucleus (CBMN) cytome index and levels of urinary polycyclic aromatic hydrocarbons (PAHs) metabolites. There was a significa...
متن کاملAcute inflammatory responses in the airways and peripheral blood after short-term exposure to diesel exhaust in healthy human volunteers.
Several epidemiologic studies have demonstrated a consistent association between levels of particulate matter (PM) in the ambient air with increases in cardiovascular and respiratory mortality and morbidity. Diesel exhaust (DE), in addition to generating other pollutants, is a major contributor to PM pollution in most places in the world. Although the epidemiologic evidence is strong, there are...
متن کاملSickness Response Symptoms among Healthy Volunteers after Controlled Exposures to Diesel Exhaust and Psychological Stress
BACKGROUND Interactions between acute exposures to environmental chemical contaminants and psychological stress may be important in situations where they are likely to co-occur, ranging in intensity from daily urban living to participation in war. Modification of symptomatic responses by stress may play a role in medically unexplained symptoms attributed to low-level chemical exposures. OBJEC...
