ABSTRACT:
The present invention provides a pharmaceutical preparation for hearing impairment, which is suitable for gene therapy of hearing impairment, that is, a pharmaceutical preparation for hearing impairment which comprises a virus envelope vector encapsulating a hepatocyte growth factor (HGF) gene or its plasmid as an active ingredient. Particularly, it is suitable as a pharmaceutical preparation for gene therapy for the purpose of prevention and treatment of deafness.
