From: Chronic hypoxia in pregnancy affected vascular tone of renal interlobar arteries in the offspring
(a) Representative images of phenylephrine-mediated vasoconstrictions in renal interlobar arteries of the control and hypoxia offspring. (b) Representative images of vasodilatation by acetylcholine based on phenylephrine-increased vascular tension. (A) The effect of chronic hypoxia during pregnancy on vascular responses to phenylephrine (PE) in offspring renal interlobar arteries. *,P < 0.05; N = 8. (B) PE-increased vasoconstriction in presence or absence of NG-Nitro-l-arginine (L-Name). #,P < 0.05; N = 6. (C) Acetylcholine (ACh)-mediated vasodilatation. The arteries were contracted with PE (1 μmoll−1) prior to addition of ACh. *,P < 0.05; N = 5–6.
