Tetrodotoxin (10-8 to 10-6 g/ml) blocked the contractile responses of isolated guinea pig urinary bladder preparation to electrical (25 and 100 Hz) neural but not to transmural stimulation and to X irradiation (50 kV, 20 kR/min, 20 kR). The irradiation had no influence on the bladder responses to electrical and hormonal (acetylcholine and histamine) stimulation. It is concluded that the X ray induced contraction is of myogenic origin and that it is possibly not related to the electromechanical coupling system.
