Overall C_CSF/C_Pt, C_ECF/C_Pt, C_CSF/C_Pu, and C_ECF/C_Pu ratios for each infusion step

	C_CSF/C_Pt	C_ECF/C_Pt	C_CSF/C_Pu	C_ECF/C_Pu
100-day fetus	2.3^a	2.3^a	6.5^a	6.5^a
120-day fetus	2.3 ± 0.5¹^b	2.1 ± 0.4¹^d	4.7 ± 1.2¹^b	4.5 ± 0.7¹^d
10-day lamb	1.1 ± 0.1²^b	1.3 ± 0.3²^d	5.6 ± 0.5¹^b	6.6 ± 0.4²^d
30-day lamb	0.7^e	1.6 ± 0.3²^c	4.9^e	6.6 ± 0.8²^c
Adult	0.4 ± 0.1³^c	0.4 ± 0.0³^d	3.4 ± 0.1²^c	3.4 ± 0.3³^d

Data are shown as mean ± S.E.M.

The overall ratios are averages of individual ratios from the five steps.

Values with different number superscripts (1-3) in each column are statistically different as determined by the Duncan's multiple comparison test (p < 0.05).
