Recovery of Peripheral Nerve Function After Axotomy: Effect of Triiodothyronine.

摘要

The rate of recovery of motor function after crushing the sciatic nerve was measured in rats treated with daily intraperitoneal injections of 3,3',5-triiodo-L-thyronine, 25 mu(g)/kg. The nerve was crushed at one of four levels and recovery of motor function was indicated by the return of toe spreading elicited as part of the vestibular placing response. The rate of recovery was calculated from the linear regression of the time to recovery on the distance from the lesion to the entry of the peroneal nerve into the anterior tibial muscle.
