Deep-brain lacunar infarct represents a significant clinical problem as it produces severe symptoms highly resistant to rehabilitation. The limited area of necrosis may facilitate neurorepair via the action of various novel neuroprotective strategies including cell-based therapies. The lesion was
The present manuscript investigates in two animal species by using two different experimental models of middle cerebral artery occlusion (permanent and transient), the neuroprotective effects of the dopamine receptor agonist apomorphine. These effects were evaluated by measuring the infarct volume
Apomorphine was administered by continuous infusion in the mouse following acute inhibition of oxidative metabolism induced by systemic administration of MPTP, and in the gerbil following transient occlusion of the carotid arteries. The dosage employed was comparable to the one used in the treatment
We observed a stroke patient with an infarct of the internal capsule interrupting the pyramidal tract who stretched his hemiplegic arm during spontaneous and apomorphine-induced yawning. The putative mechanism by which yawning can induce the paradoxical motor response of the plegic arm in the
Previous studies showed that bladder hyperactivity after cerebral infarction in Sprague-Dawley (SD) rats was mediated in part by D2 dopaminergic and NMDA glutamatergic mechanisms. In the present experiments, the interaction between dopaminergic and glutamatergic excitatory mechanisms in the control
Hypothermia may be an ideal neuroprotective intervention in hypoxic-ischemic encephalopathy after perinatal asphyxia. The present study describes the long-term effects of prolonged resuscitative whole-body hypothermia initiated 2 h after hypoxic-ischemic injury on brain morphology and
Following right middle cerebral artery occlusion in the rat, striatal dopaminergic system alterations were studied. Dopamine turnover was assessed by measuring 3,4-dihydroxyphenylacetic acid concentrations and dopamine receptor function, by measuring (3H)-Spiroperidol binding. There was a transient
Unilateral cerebral infarctions are produced in 30-50% of all gerbils subjected to ipsilateral ligation of a common carotid artery. It has previously been shown that this infarction is associated with a major depletion if ipsilateral brain dopamine. The present studies characterize the spontaneous
In order to test therapeutics, functional assessments are required. In pre-clinical stroke research, there is little consensus regarding the most appropriate behavioural tasks to assess deficits, especially when testing over extended times in milder models with short occlusion times and small lesion
Context: Hydroxysafflor yellow A (HSYA) has been shown to have neuroprotective effects in cerebral infarction. However, its underlying roles in apoptosis and inflammation in Parkinson's disease (PD) are unknown.
