| Research Abstract |
Hepatocyte growth factor (HGF) has been reported to accelerate recovery in central nerve system, but its function in peripheral nerve system is unclear. We transfected HGF using replication-defective herpes simplex virus vector into crushed facial nerve. Recovery from facial nerve palsy was accelerated clinically, electrophysiologically, and pathologically. Transfected cells were detected using immunohistochemicalstaining.Close relationship between HSV and sudden deafness or vestibular neuritis has been reported. We inject HSV-1 or HSV-2 into tympanic cavity of mice. Vertigo and hearing loss was observed in those mice. HSV-infected, apoptotic cells were found in stria vascularis; however, apoptotic cells found around Corti’s organ was not infected with HSV. Apoptosis induction after HSV infection differed according cell types.
