TABLE 2.

Stability of sciatic nerve myelin during perfusion

Myelin structure in nerves mounted in a perfusion chamber was assessed by XRD; patterns were recorded immediately after dissection and at 5 and 20 h during the perfusion with physiological saline. See legend to Table 1 for details.

^a P0(−/−) sciatic nerve was too weak to withstand lengthy perfusion, so only data at 5 h are shown.
