Distribution and time course of protein extravasation in the rat spinal cord after contusive injury

Abstract

We have previously characterized a graded, spinal cord contusive injury in the rat. We have now used this reproducible model to examine vascular permeability to horseradish peroxidase (HRP) after injury. The relationship between severity of injury and distribution of protein extravasation was evaluated at 3 h after injury. After mild injury, tracer was primarily confined to central gray matter and the ventral part of the dorsal columns. After moderate injury, protein extravasation was similar to that observed after mild injury, with the exception that the central hemorrhage included pericentral while matter and occasionally extended to the pial surface. After severe injury, reaction product (RP) was more densely distributed within the central cord and peripheral white matter. The axial extent of tracer at sites proximal and distal to the impact site increased with severity of injury. At 2.0 cm from the injury, no leakage of tracer was noted after mild injury. In contrast, after moderate and severe injury limited microvascular leakage of HRP was noted. Furthermore, after severe injury, in addition to local sites of microvascular leakage, intense RP was present in the dorsal columns up to at least 2.0 cm from the injury. The time course for re-establishment of the blood-spinal cord barrier to protein was evaluated from 3 h to 14 days after moderate injury. At 3 h to 1 day, protein leakage was maximal and coincided with sites of extravasated blood components, although was consis…

  • In rodent studies, blood-spinal cord barrier disruption occurs within 5 min after spinal cord trauma, lasts for up to 28 days after the initial injury, and spreads along the entire length of the cord.

    “On the basis of experimental rodent studies, BSCB disruption occurs within 5 min after spinal cord trauma (385), lasts for up to 28 days after the initial injury, and spreads along the entire length of the cord (441, 478, 644).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
