Table. 1. Levels of extracellular matrix components in the lungs of the control and the experimental group of animals.

Parameters	Group I (Control)	Group II (B(a)P)	Group III (CAP)	Group IV (B(a)P + CAP)
Elastin	2.63 ± 0.02	6.45 ± 0.64*	2.62 ± 0.02	3.03 ± 0.34†
Uronic acid	0.31 ± 0.002	3.28 ± 0.31*	0.33 ± 0.003	1.12 ± 0.13†
Hexosamine	0.64 ± 0.006	3.66 ± 0.34*	0.65 ± 0.006	1.17 ± 0.14†

Units for elastin, uronic acid and hexosamine-microgram/100 mg tissue. Each value is expressed as mean ± S.D. for six mice in each group. ^*Statistical significance is at P < 0.05 as compared with Group I; ^†Statistical significance is at P < 0.05 as compared with Group II. S.D., standard deviation; B(a)P, benzo(a)pyrene; CAP, capsaicin.
