Task: Answer Verification
Input (English): Question: Does granulocyte colony-stimulating factor affect contusion size , brain edema or cerebrospinal fluid glutamate concentrations in rats following controlled cortical impact?
Answer: A single injection of G-CSF did not influence cortical contusion volume, brain edema, or glutamate concentrations in CSF determined 24 hours following CCII in rats. G-CSF, administered 30 minutes following experimental TBI, failed to exert neuroprotective effects.
Output (English): no
