GABAergic contribution to rat bladder hyperactivity after middle cerebral artery occlusion

Sayoko Kanie, Osamu Yokoyama, Kazuto Komatsu, Koichi Kodama et autres

To evaluate the influences of gamma-aminobutyric acid (GABA) mechanisms on bladder hyperactivity after left middle cerebral artery occlusion, cystometric recordings were obtained from unanesthetized female rats. Intracerebroventricular administration of both muscimol (GABA(A) receptor agonist; 0.1-10 nmol) and baclofen (GABA(B) receptor agonist; 0.1-3 …
