Abstract:
The early effects of gentamicin treatment on the inner ear glycocalyx were investigated using two cationic probes, colloidal thorium and cationized ferritin. Gentamicin treatment resulted in a diminished thorium reactivity of both the endolymphatic and perilymphatic glycocalyx of the hair cells after 1 day and complete abolishment of reactivity after 5 days. Cationized ferritin reactivity of the perilymphatic and endolymphatic glycocalyx was not significantly influenced. The cytochemistry of the inner ear glycocalyx and the possible biochemical changes induced by gentamicin are discussed.
