Values are means ± SE. EUS, external urethral sphincter.
EUS tonic activity (n = 4) and EUS bursting activity (n = 2).
EUS bursting activity.
EUS tonic activity.
Drugs were tested in 5 of the chronic T8–9 SCT rats.
P < 0.05, significantly increased compared with control before drugs.
P < 0.05, significantly reduced compared with records after 8-OH-DPAT.
