| pubmed-article:583985 | pubmed:abstractText | Intra-arterial injections of bradykinin cause increases in blood pressure and increased impulse rates in single sympathetic efferent fibres. The peptide also causes one or more large bladder contractions, which are associated with increased impulse rates in pelvic nerve efferent fibres whose spontaneous discharges are temporally associated with increases in intravesical pressure. These induced increases in pelvic nerve discharge and intravesical pressure could be abolished or greatly reduced by interference with conduction in pathways which mediate reflex bladder contractions. It is concluded that bradykinin has little direct action on the bladder, and that the large contractions which result from its administration are mediated by the central nervous system. | lld:pubmed |
