we investigated the effect of cigarette smoke condensate ( csc ) , two basic fractions ( bia and bib ) of csc , the ethanol-extracted weakly acidic fraction ( wae ) , and the methanol-extracted neutral fraction ( nmeoh ) on the clonal growth rate , plasminogen activator ( pa ) activity , cross-linked envelope ( cle ) formation , and ornithine decarboxylase activity , epidermal growth factor ( egf ) binding , thiol levels , and dna single strand breaks in cultured human bronchial cells .
