Preterm fetal hypoxia-ischemia causes hypertonia and motor deficits in the neonatal rabbit: a model for human cerebral palsy?
Prenatal hypoxia-ischemia to the developing brain has been strongly implicated in the subsequent development of the hypertonic motor deficits of cerebral palsy (CP) in premature and full-term infants who present with neonatal encephalopathy. Despite the enormous impact of CP, there is no animal model that reproduces the hypertonia and motor disturbances of this disorder. We report a rabbit mode...
متن کاملA model of cerebral palsy from fetal hypoxia-ischemia.
Disorders of the maternal-placental-fetal unit often results in fetal brain injury, which in turn results in one of the highest burdens of disease, because of the lifelong consequences and cost to society. Investigating hypoxia-ischemia in the perinatal period requires the factoring of timing of the insult, determination of end-points, taking into account the innate development, plasticity, and...
متن کاملNear-term fetal hypoxia-ischemia in rabbits: MRI can predict muscle tone abnormalities and deep brain injury.
BACKGROUND AND PURPOSE The pattern of antenatal brain injury varies with gestational age at the time of insult. Deep brain nuclei are often injured at older gestational ages. Having previously shown postnatal hypertonia after preterm fetal rabbit hypoxia-ischemia, the objective of this study was to investigate the causal relationship between the dynamic regional pattern of brain injury on MRI a...
متن کاملCerebral hypoxia and ischemia in preterm infants
Premature birth is a major public health issue internationally affecting 13 million babies worldwide. Hypoxia and ischemia is probably the commonest type of acquired brain damage in preterm infants. The clinical manifestations of hypoxic-ischemic injury in survivors of premature birth include a spectrum of cerebral palsy and intellectual disabilities. Until recently, the extensive brain abnorma...
متن کاملApoptosis in a neonatal rat model of cerebral hypoxia-ischemia.
BACKGROUND AND PURPOSE The mechanisms of excitotoxic cell death in cerebral ischemia are poorly understood. In addition to necrosis, apoptotic cell death may occur. The purpose of this study was to determine whether an established model of cerebral hypoxia-ischemia in the neonatal rat demonstrates any features of apoptosis. METHODS Seven-day-old neonatal rats underwent bilateral, permanent ca...
