Analysis of heart and lung weight in controls and PO, LCV-PO, and RCV-PO animals

	Controls (n = 8)	PO (n = 12)	LCV-PO (n = 9)	RCV-PO (n = 10)
Age at termination, wk	28.2 ± 1.1	27.3 ± 1.8	26.5 ± 2.8	25.6 ± 1.9
Postoperative recovery, wk		7.3 ± 0.5	7.3 ± 0.3	7.5 ± 0.5
Body wt, g	1011 ± 56	1030 ± 77	969 ± 94	946 ± 86
Heart wt, %body wt	0.65 ± 0.08	0.57 ± 0.05	0.59 ± 0.08	0.60 ± 0.07
Wet lung wt, %body wt	0.50 ± 0.08	0.41 ± 0.07	0.48 ± 0.17	0.42 ± 0.05
Dry lung wt, %body wt	0.09 ± 0.01	0.08 ± 0.03	0.09 ± 0.05	0.09 ± 0.01

Values are means ± SD; n, number of animals. No significant effect (P < 0.05) was found between groups (by ANOVA).
