1.	Seizures (Seizure) 06/01/2014 - "Finally, RIIβ knockout was protective against bicuculline-induced seizure susceptibility. " 10/01/1982 - "At 14 h following administration, TMT provided little protection against bicuculline, INH or PTZ induced seizures. " 12/01/2005 - "Aim of the study is to investigate the involvement of parahippocampal subregions in the generation and in the propagation of focal epileptiform discharges in an acute model of seizure generation in the temporal lobe induced by arterial application of bicuculline in the in vitro isolated guinea pig brain preparation. " 03/01/2003 - "However, previous studies also suggested that the DLSC and the nearby intercollicular nucleus (ICN) are part of a midbrain anticonvulsant zone capable of suppressing tonic convulsions when activated with bicuculline. " 12/01/2000 - "In the present study, unilateral focal microinfusion of picomole quantities of bicuculline induced behavioural (focal and generalized) seizures in deep layers of all parts of the PC in two rat strains, Wistar and SD. "
2.	Bradycardia 04/01/1999 - "Intracerebroventricular administration of 0.3 and 0.5 nmol of bicuculline produces an increase in blood pressure and a slight bradycardia in non-epileptic Wistar rats. " 07/26/1996 - "Bicuculline induced cardiorespiratory changes which consisted mainly of an augmented respiratory rate, through shortening of expiratory duration, and of bradycardia. " 02/01/1992 - "Both the depressor and bradycardia responses of the nucleus fastigius and nucleus vestibularis superior were blocked by preinjection of bicuculline (a GABAergic receptor blocker) into the rostral ventrolateral medulla. " 10/01/2003 - "The aortic baroreflex bradycardia was hardly affected by DMH or dPAG stimulation when bicuculline (5 pmol), a specific GABAA receptor antagonist, had previously been microinjected into the NTS. " 08/01/1990 - "The bradycardia/depressor response evoked from lobule IX b in the anaesthetized decerebrate rabbit was not altered significantly following a microinjection of either kainic acid or bicuculline into the ipsilateral NTS. "
3.	Hyperalgesia 08/01/2010 - "The effects on bicuculline-induced allodynia in a touch-evoked agitation test and on pain threshold index in a hot-plate test were assessed. " 11/18/1993 - "Prior spinal cord infusion of bicuculline, a gamma amino butyric acidA (GABAA) receptor antagonist, significantly reduces the severity of joint inflammation and prevents the development of heat hyperalgesia. " 03/01/2015 - "Overexpression of wild-type STEP61 to resume its enzymatic activity significantly blocked the mechanical allodynia evoked by bicuculline and more importantly, alleviated chronic inflammatory pain (n = 6 in each group). " 03/01/2009 - "By contrast, microinjection of GABAA antagonist bicuculline remarkably reduced the thermal hyperalgesia of the CFA-inflamed hindpaws, indicating an inhibitory effect of SI output in the chronic pain state. " 11/18/1993 - "Joint inflammation and hyperalgesia are reduced by spinal bicuculline."
4.	Apnea 10/01/2007 - "Subsequent bicuculline administration reversed the effects of CGS and prevented the production of apnea compared with control at higher SLN stimulation levels. " 04/01/2001 - "Bicuculline also reduced SLN-induced apnea and duration of poststimulation apnea (P < 0.05). " 01/01/2006 - "Prior injection of the GABA(A)-receptor blocker bicuculline at 14 and 21 days eliminated the CGS-induced decrease in frequency and apnea. " 12/01/2002 - "Microinjection of the bicuculline produced apnea, whereas microinjection of CGP-35348 produced a decrease in Ti and an increase in expiratory duration. " 04/01/2001 - "We studied the effect of the GABA(A) receptor blocker bicuculline, given intravenously and intracisternally, on apnea induced by SLN stimulation. "
5.	Spinal Cord Injuries (Spinal Cord Injury) 04/01/2008 - "4. Bicuculline-induced effects on phrenic nerve activity were eliminated after C8 spinal cord transection and regular phrenic rhythm resumed indicating that bicuculline was not acting directly on phrenic motoneurons. " 10/28/2010 - "High spinal cord transection or infusion of the GABA(A) receptors antagonist, bicuculline, into the cisterna magna is effective in disrupting the reflex bradycardia. " 01/01/1986 - "The effects of the gamma-aminobutyric acid (GABA) antagonist bicuculline (BCC) on hindlimb motor performance was examined in mature spinal cats with spinal cord transections made either on the day of birth or at approximately two weeks postpartum and in chronic adult cats with spinal transections made in adulthood. " 03/01/2008 - "At 4 weeks after Th9-10 spinal cord transection awake cystometry and recordings of external urethral sphincter electromyogram were performed to examine the effect of intrathecal application of the gamma-aminobutyric acid A and B agonists muscimol and baclofen or the gamma-aminobutyric acid A and B antagonists bicuculline and saclofen (Tocris Cookson, Ellisville, Missouri), respectively, at the level of the L6-S1 spinal cord.
