Responses to sulfur dioxide and exercise by medication-dependent asthmatics: effect of varying medication levelsW S Linn
Environmental Health Service, Rancho Los Amigos Medical Center, University of Southern California, Downey
Arch Environ Health 45:24-30. 1990..High medication improved baseline lung function and prevented most bronchoconstrictive effects of SO2/exercise. High medication also increased heart rate and apparently induced tremor or nervousness in some individuals...

The effect of ambient air pollution on exhaled nitric oxide in the Children's Health StudyK Berhane
Dept of Preventive Medicine, Keck School of Medicine, University of Southern California, Los Angeles, CA 90089 9011, USA
Eur Respir J 37:1029-36. 2011..In summary, short-term increases in PM₂.₅, PM₁₀ and O₃ were associated with airway inflammation independent of asthma and allergy status, with PM₁₀ effects significantly higher in the warm season...
A study of twelve Southern California communities with differing levels and types of air pollution. I. Prevalence of respiratory morbidityJ M Peters

A study of twelve Southern California communities with differing levels and types of air pollution. II. Effects on pulmonary functionJ M Peters
Department of Preventive Medicine, University of Southern California School of Medicine, Los Angeles, USA
Am J Respir Crit Care Med 159:768-75. 1999..For boys, significant associations were seen between peak O3 exposures and lower FVC and FEV1, but only in those spending more time outdoors. These findings underline the importance of follow-up of this cohort...

Rancho Los Amigos National Rehabilitation Center, Downey, CA 90242, USA
Spinal Cord 39:263-8. 2001..Smoking-related FVC loss is important in persons with SCI as in others, although at higher levels it may be obscured by SCI-related loss...

Environmental Health Service, Rancho Los Amigos, National Rehabilitation Center, Downey, CA 90242, USA
Chest 119:402-8. 2001..Some asthma medications mitigate the SO(2) response, which is not fully understood but appears to involve multiple mechanisms...

Department of Preventive Medicine, University of Southern California, Los Angeles 90089, USA
Pediatr Pulmonol 34:112-21. 2002..We conclude that RI in children who are well enough to attend school may reduce expiratory flow rates. These effects are greater for children with active asthma or hay fever than in those without, and may be inversely related to age...
