Vascularization and microvascular permeability were assessed in a comparative study of solid (organized) and cell-suspension (dissociated) fetal nigral grafts implanted in the dopamine-deprived striatum of adult rats. Both graft types were analyzed by chromogen detection of intravenously injected horseradish peroxidase (HRP), which outlined vessel walls,(More)
Nonlinear problems arising in modeling applications are frequently parameter dependent, so that families of solutions are of interest. Such problems naturally lend themselves to interactive computation that exploits parameter continuation methods combined with visualization techniques. Visualization provides both understanding of the solution set and(More)
The standard Chimera Domain Decomposition approach to numerically solving the conservation laws of uid dynamics can give rise to anomalous ow eld features near subdomain boundaries. Keeling, Tramel, and Benek hypothesized that these anomalous behaviors are caused by interpolation across shocks at the artiicial boundaries and can be eliminated by using the(More)
After spinal cord injury, abnormal responses of spinal cord neurons to sensory input lead to conditions such as autonomic dysreflexia, urinary bladder dyssynergia, muscle spasticity and chronic pain syndromes. These responses suggest that the spinal cord undergoes marked reorganization after an injury. In previous studies, we demonstrated changes in(More)
The retrograde tracer 1,1'-dioctadecyl-3,3,3',3'-tetramethylindocarbocyanine perchlorate (DiI) was used to label sympathetic preganglionic neurons (SPN) and motoneurons (MN) in postmortem human spinal cord. Seven months after microinjection of DiI into the ventral part of spinal thoracic segments T4 and T8, DiI-labelled neurons were identified and analyzed.(More)
The effects of altering the rate, manner and vehicle used for intracerebral injection upon microvascular permeability were studied in Sprague-Dawley rats employing horseradish peroxidase histochemistry. The volume of vehicle delivered and the site of intracerebral injection were kept constant. In comparison to continuous infusion, vascular permeability was(More)
