Contractions of the uterus were induced with acetylcholine (Ach) (1 microM), PGF2alpha (0.1 microM), oxytocin (10-3 U/ml), KCl (56.3 mM), tetraethylammonium (TEA; 1 and 10 mM), 4-aminopyridine (4-AP; 5 mM), glipizide (30 microM), a nitric oxide synthase (NOS) inhibitor (LNNA; 10-3M), a beta-receptor blocker (propranolol; 10 microM), and a cyclooxygenase inhibitor (indomethacin; 60 microM).

Acetylcholine (ACh, 1 nM-10 microM) induced endothelium-dependent relaxation of arterial rings precontracted with norepinephrine (NE, 1 microM) in a concentration-dependent manner.
The ACh-induced relaxation observed in the presence of L-NAME was significantly reduced by a combination of iberiotoxin (0.1 microM) and apamin (1 microM), and almost completely blocked by 4-aminopyridine (5 mM).

In arteries contracted with prostaglandin F (2 alpha) (2.5 - 10 microM), relaxation evoked by ACh (0.01 - 3 microM) was abolished by a combination of charybdotoxin (ChTX, 0.1 microM) plus apamin (Apa, 0.1 microM) and was inhibited by 68+/-6% (n=6) by 4-aminopyridine (4-AP, 5 mM). 3.
SMCs hyperpolarization to ACh (1 microM) was abolished by high K (+) solution or by ChTX/Apa.
