[The activation of p38MAPK in hypoglossal necleus and the effect of nerve growth factor on regeneration following hypoglossal nerve crush in rat].

p-p38MAPK was slightly expression in normal hypoglossal nucleus but intensively expression after injury. NGF can down-regulate p-p38MAPK expression in the motoneurons of hypoglossal nucleus after hypoglossal nerve was crushed. Exogenous NCF can protect damaged neurons and promote nerve regeneration after hypoglossal nerve crush injury in rats.
