Experimental groups and design.
| Acute Phase | |
|---|---|
| AO | Acute O3 (exposure to 0.7 ppm of O3 for 4 h for 15 days). |
| AI | Acute intact (exposed to O3 free air for 4 h and without CUR supplementation for 15 days). |
| AC | Acute CUR (diet supplemented with CUR and exposed to O3-free air for 15 days). |
| AP | Acute preventive (diet supplemented with CUR provided 7 days prior to exposure to O3 for 15 days and continued CUR supplementation). |
| AT | Acute therapeutic (exposure to O3 7 days prior to the administration of the diet supplemented with CUR for 15 days and continued exposure to O3 until day 15). |
| Chronic phase | |
| CO | Chronic O3 (exposure to 0.7 ppm of O3 for 4 h for 60 days). |
| CI | Chronic intact (exposure to O3-free air for 4 h and without CUR supplementation for 60 days). |
| CC | Chronic CUR (exposure to O3-free air for 4 h with diet supplemented with CUR administered for 60 days). |
| CP | Chronic preventive (diet supplemented with CUR provided 7 days prior to exposure to O3 for 60 days; CUR-supplemented feeding continued until day 60). |
| CT | Chronic therapeutic (exposure to O3 for 7 days prior to the administration of the diet supplemented with CUR for 60 days; exposure to O3 continued until day 60). |
