What are the key steps in the surgical procedure?
The procedure involves skin and muscle removal, laminectomy, and compression using calibrated forceps.
How do you ensure the reproducibility of the spinal cord injury?
By following a standardized surgical protocol and using calibrated tools for injury generation.
What precautions should be taken during surgery?
Maintain a sterile field, avoid pressure on the spinal cord, and monitor reflexes throughout the procedure.
What post-operative care is recommended for the mice?
Administer pain relief, monitor hydration, and provide a quiet recovery environment.
What techniques are used to assess tissue damage?
Histochemical techniques are employed to evaluate the extent of spinal cord injury.
How is the severity of injury determined?
Injury severity is assessed based on the compression parameters and histological analysis.
