Figure 2. Comparison of CBF (top panel) and cortical vascular resistance (bottom panel) responses in untreated and NOS-inhibited late-gestation fetal sheep.

Results (means ±s.e.m.) are shown for eight control and eight l-NAME-treated fetuses. ^* Significantly different from initial baseline; § significantly different between groups. The rise in CBF in NOS-inhibited fetuses from the lowered baseline after l-NAME infusion was not significantly different.
