Intravenous administration of human mesenchymal stem cells after noise- or drug-induced hearing loss in rats.

abstract：:In this experimental study in the rat, compound 48/80--a potent degranulating drug of mast cells--was instilled in the external auditory meatus towards the tympanic membrane. Moreover, effusion material was produced in the attic space by blocking the tympanic isthmus with a piece of Gelfoam applied through the tympani...
