title: Galanin: a potent modulator of excitatory neurotransmission in the human urinary bladder.
abstract: Galanin (GAL) produced a concentration (0.3-100 nM)-related inhibition of the atropine-sensitive component of the contractions induced by field stimulation of detrusor strips from the dome of the human urinary bladder. GAL had an ED50 of 2 nM for the inhibition. The effect of GAL was prevented by atropine (1 microM) and was not seen when the strips were stimulated with a cholinomimetic or KCl. These data suggest a possible neuromodulator role of GAL in the human urinary bladder.
