ABSTRACT
In this report we present a 45 year old man with horizontal diplopia following minor head trauma. Neurological examination was normal except for unilateral adduction paresis of the right eye. Brain magnetic resonance imaging (MRI) revealed a contusion area 7 mm in diameter at the inferiorposterior portion of the mesencephalon. We thought that this contusion affected the sub-nucleus of oculomotor nerve and caused isolated adduction paresis of the right eye. This relatively rare entity is discussed in the light of the available literature.
ABSTRACT
The mechanism of spinal cord injury and repair therapy after nerve injury is currently a hotspot of neuroscience research.Duplicating animal models plays a key role in experimental therapeutics of spinal cord injury.This review systematically describes the progress in animal models for spinal cord injury including contusion, compression, transection, ischemic,distraction and chemical-mediated injury,which have been established at home and abroad.Based upon the aforementioned models,some applications in experimental therapeutics are simultaneously enumerated.All these information provides scientific guidance for the experimental novel drugs′screening.
