when cig was quantified by electroimmunoassay , intact lung parenchyma contained approximately equal to 0.4 % cig , asg contained 3-4.5 % cig , abm contained 0.1-0.9 % cig and tbm contained 1.5 % -7.2 % cg . the evidence suggests that cig is a chemical constituent of lung connective tissue matrix where it may influence the function of alveoli .
