Assessment of competency in anesthesiology.

abstract：:Rats were given standardized injections of 3H-L-proline into the trigeminal ganglion and 14C-lidocaine hydrochloride at the infraorbital foramen. The 3H-L-proline was always injected 2.5 h before removal of the nerve. Lidocaine, 1, 2, and 4%, produced a concentration-related inhibition of entry of 3H-labeled rapid axo...
