[Morphofunctional characteristics of the cat spiral ganglion in neurosensory hypoacusis].

Morphofunctional disorders in spiral ganglion in animals of different groups of age with neurosensory hardness of hearing due to ototoxic antibiotics have been shown. Antibiotic intoxication in kittens in early postnatal period arouses essential deviation from normal process of development of neurocytes in spiral ganglion. In the first rate low level of their metabolic activity must be shown. Delay of differentiation of neurocytes makes essential influence on the development of spiral ganglion as the unit of transmission of audio-information. The main feature of morphofunctional disorders in neurocytes of ganglion of grown-up animals is inhibition of protein synthesis mechanism activity.
