Fig. 1. Relative changes (mean ± SE) of blood flow volume (BFV) after injection of oxytocin (oxytocin, solid circles; n = 7) and saline (open squares; n = 5). Values at time ‘5’
(prior to oxytocin injection) were set at 100%. (a) Relative change of BFV in the uterine artery ipsilateral to the former pregnant horn (UA-ipsi) on day 2. (b) Relative change of
BFV in UA-ipsi on day 5. (c) Relative change of BFV in the uterine artery contralateral to the former pregnant horn (UA-cont) on day 2. (d) Relative change of BFV in UA-cont on
day 5. Significantly different from value at time ‘5’ (P < 0.05).
