the aims of our study were , ( i ) to utilize this loss of requirement for pyruvate by carcinogen-altered cells as a way of selecting out and quantitating the numbers of altered cell populations induced in tracheas exposed to 200 micrograms 7,12-dimethylbenz [ a ] -anthracene ( dmba ) -beeswax pellets for different lengths of time , ( ii ) to determine the constancy of these numbers at increasing time intervals after the exposure , ( iii ) to look for distinctive growth properties in cell populations that may be related to the exposure conditions .
