Objectives:: To determine the prevalence of H.

Nerve growth factor with fibrin glue in end-to-side nerve repair in rats.

Purpose: To determine the effects of end-to-side nerve repair performed only with fibrin glue containing nerve growth in rats.

Methods: Seventy two Wistar rats were divided into six equal groups: group A was not submitted to nerve section; group B was submitted to nerve fibular section only. The others groups had the nerve fibular sectioned and then repaired in the lateral surface of an intact tibial nerve, with different procedures: group C: ETS with sutures; group D: ETS with sutures and NGF; group E: ETS with FG only; group F: ETS with FG containing NGF.
