  1. Caspase activity in freshly prepared TIIcells of rats exposed to air (control) or oxygen for 48 hrs (hyperoxia) was determined colorimetrically as described in Materials and Methods. Values are means ± S.D. given in arbitrary units (control = 100). Asterisk indicates a significant difference to control (p < 0.05).
