METHODS A total of 196 male Sprague-Dawley rats, 3-4 wk of age at the beginning of the
exposure period, were identified by number and assigned randomly to Ozone and Control …

These studies examined the effects of exposure to near environmental levels of ozone (O3)
on the unanesthetized unrestrained rat as well as the influence of changes in ambient …

The potential for irreversible lung impairment resulting from life-long ozone (O3) exposure
remains uncertain. To address this question, young adult rats (male, F-344) were exposed to …

Fourteen healthy normal volunteers were randomly exposed to air and 0.5 ppm of ozone
(O3) in a controlled exposure chamber for a 2-h period during which 15 min of treadmill …

Minor differences in lung growth and development during childhood have been considered
as a potential cause of rapid decline in pulmonary function in adulthood. Inhalation of ozone …

The effects of low concentrations of ozone (10028156) on pulmonary function were studied
in adult and neonatal rats. One day old or 7 week old male F-344-rats were exposed to 0 …

The degree of lung injury caused by prolonged inhalation of low levels of ozone (O3) is of
interest since urban environmental levels periodically reach 0.2 to 0.3 ppm. Since the area …

Cats exposed to 0.26, 0.50, or 1.0 ppm of ozone (O3) for 4.7 to 6.6 hours showed changes in
lung cytology throughout the airways and parenchyma. Although the cellular changes were …

Abstract Weanling male Sprague-Dawley rats were fed either a synthetic diet supplemented
with 11 mg vitamin E/kg body weight (to approximate average US human dietary intake) or a …

The morphologic changes in the centriacinar region of lungs from 14 rats exposed to either
filtered air (8) or 0.95 ppm ozone (6) 8 hours daily for 90 days were examined morphologi …
