ABSTRACT
In our experience, accidents involving all-terrain vehicles are an increasingly frequent cause of brain injury in children. The risk associated with operation of these vehicles is not fully appreciated and should be better publicized. We believe that it is possible to delineate several steps that could significantly reduce the risk to the pediatric population without curtailing the recreation altogether. Although construction design has promised to produce safer vehicles, our experience has shown that extreme injury is still possible with the newer four-wheel machine.

Electrical stimulation in lateral sites of the upper cervical spinal cord evoked vasodilatation after adrenergic blockade. Sympathetic fibres mediating sustained vasodilatation were shown to be separate from adrenergic sympathetic fibres since the adrenergic vasoconstrictor response in the paw evoked by vasomotor stimulation in the medulla was not reversed to vasodilatation after bretylium.
