Is there a probenecid sensitive transport system for monoamine catabolites at the level of the brain capillary plexus?

abstract：:Any spinal cord injury carries the potential for persistent disability affecting motor, sensory and autonomic functions. To prevent this outcome, it is highly desirable to block a chain of deleterious reactions developing in the spinal areas immediately around the primary lesion. Thus, early timing of pharmacological ...
