to determine what biochemical indexes might be useful in measuring the endothelial response to hyperoxia in vitro we exposed endothelial cell monolayers ( ecm ) from pig aortas to either hyperoxic ( 95 % o2:5 % co2 , 1 atm ) or control conditions ( 95 % air:5 % co2 ) and made the following measurements : ( a ) dna and protein contents remaining in the ecm ;
