Increase in myelin basic protein in CSF after brain surgery

Myelin basic protein in spinal fluid was measured with a radioimmunoassay method after surgery of brain tumors and posttraumatic brains in thirteen cases. Three cases were studied daily for up to three weeks. Immediately after the operation the values were high but then successively returned to normal. Repeated measurement of the myelin basic protein in spinal fluid seem to be useful for assessing the healing rate of brain tissue after surgery for brain tumors and after other brain damage.
