5 Fig. 4 Relationship between plasma MMP-9 and leukocyte count for baseline and biweekly values during and after RT. International Journal of Radiation Oncology • Biology • Physics  , DOI: ( /S (03) )

6 Fig. 5 Temporal variation of MMP-3 plasma assays. Heavy dotted horizontal lines denote normal range (24 ± 8 ng/mL). International Journal of Radiation Oncology • Biology • Physics  , DOI: ( /S (03) )

7 Fig. 6 Temporal variation of lung clearance of inhaled DTPA aerosol, expressed as the biologic half-time and normalized to baseline values of 100%. Reduced half-time values of Subjects 2 and 7 during the first 100 days corroborated diagnosis of radiation pneumonitis.
