Pulmonary function tests (PFTs) of untreated and DS1 treated dogs at Week 13 post right lung irradiation.

Values are shown as means and standard deviations (SDs) at Week 13 (n = 5 for both groups).P values were calculated between the control (No DS1 infusion) and the treated (+DS1 infusion) groups.DLCO-Hct: Single breath diffusing capacity-hematocrit.IC: Inspiratory capacity.ERV: Expiratory reserve volume.TLC: Total lung capacity.RV: Residual volume directly obtained by neon dilution during the DLCO measurements.FRC: Functional residual capacity.Percentage (%) of PFTs was based on the pre-irradiation values.N.S.: not significant.
