... responses in the dome preparations; relaxation at 10 ––8 g/ml and contractions at 10 ––7 –10 ––6 g/ml. In the trigone preparations, 10 ––8 –10 ––6 g PGE 1 /ml caused dose-dependent contractions. 10 ––8 –10 ––6 g PGE 2 /ml and 10 ––7 –10 ––6 g PGF 2Α /ml induced dose-dependent contractions of the dome...

... activity nor activation by high external potassium, norepinephrine, or acetylcholine. Fenpiverinium blocked the increase in frequency of phasic-rhythmic contractions and the tonic tension development induced by acetylcholine. Fenpiverinium did influence neither spontaneous phasic activity nor activation...

...M. Gardi; F. Nigro; E. Ragazzi; A. Volpe; A. Totaro; E. Sacco; F. Pinto; P. Bassi Introduction: Normal and abnormal bladder contractions are principally mediated by acetylcholine released from postganglionic parasympathetic nerves. Since amikacin was reported to affect neurotransmission...

...; however, contraction of prostatic tissues in vitro needs a higher concentration of phenylephrine than the physiological level. To investigate this discrepancy, we investigated the functional importance of the Ca 2+ -activated K + channel (K Ca channel) of human prostatic smooth muscle cells...
