Is viscosity important in the production of blood-brain barrier disruption by intracarotid contrast media?

abstract：INTRODUCTION:Transplantation procedures using intraparenchymal injection of stem cells result in tissue injury in addition to associated surgical risks. Intravenous injection of mesenchymal stem cells gives engraftment to lesions, but the method has low efficiency and specificity. In traumatic brain injuries (TBI), the...
