Mice were exposed to 1 ppm O3, 3 hr/day, for 5 consecutive days. Separate groups of mice were infected with influenza following each of the individual exposures. A twofold increase in the incidence of mortality and a 3-day decrease in mean survival t

The effect of the time of exposure to an aerosol of viable microorganisms on the incidence of respiratory infections associated with a 3 h exposure to ozone (O3) was studied. The 157 and 196 μg m 3 (0.08–0.1 ppm) levels of O3 used occur regularly

Studies were conducted to investigate the effect of ozone (O 3 ) in prolonging pentobarbital (PEN)-induced sleeping time (S.T.). Since O 3 is a common air pollutant, an O 3 -induced alteration of mechanisms of drug action could have public health imp

The effects of inhalation exposure of mice or rats to 9.4 mg/m3 volcanic ash, 2.5 mg/m3 SO2, or both on host defense mechanisms were assessed. Cytologic changes in pulmonary lavage fluid included an increase in percentage polymorphonuclear leukocytes

The influence of nitrogen dioxide (NO 2 ) on pentobarbital (PEN)-induced sleeping time (S.T.) was investigated in mice. Acute exposure to concentrations as low as 470 μg NO 2 m 3 (0.25 ppm) caused a significant increase in PEN-induced S.T. No signif

The study reported herein evaluates the influence of a chronic exposure to an urban pattern of NO2 (continuous baseline exposure of 0.2 ppm, on which were superimposed two 1-h spikes of 0.8 ppm NO2, 5 d/wk) as compared to the baseline exposure to det

The effects of the combined action of ozone (O 3 ) and sulfuric acid (H 2 SO 4 ) aerosol on host susceptibility to an aerosol of viable microorganisms were studied. Exposure to O 3 (0.196 mg/m 3 ) was for 3 h, while exposure to H 2 SO 4 (0.9 mg/m 3 )

A mechanized wheel was constructed for use in evaluating the interaction of exercise and gaseous pollutants such as O/sub 3/ and NO/sub 2/. Immediately after the pollutant exposure, both exercised and nonexercised female mice (CD-1) were combined wit

In this study the effects of phosgene inhalation on host resistance models representative of bacterial, viral, and neoplastic lung diseases were assessed. A single Ch exposure to concentrations of phosgene of 0.025 ppm and above significantly enhance
