TABLE 3.

Collagen per mm luminal circumference and percentage collagen and elastin of dry defatted weight.

	Male db/db+	Male db/db
Collagen (mg × 10–3/mm)	6.00 ± 0.49 (8)	4.42 ± 0.08* (10)
Collagen (%)	14.6 ± 0.5 (9)	13.8 ± 1.1 (10)
Elastin (%)	32.1 ± 0.9 (9)	30.8 ± 2.1 (10)
Collagen/elastin ratio	0.450 ± 0.020	0.454 ± 0.012

Means ± SEM (No. of mice). Percentages of collagen and elastin were determined for 4 pools of aortas from 2 to 3 mice. * P < 0.05 db/db versus db/db+. Collagen content for aorta from female mice is listed in the result section, while elastin content was not determined in female mice.
