    ABSTRACT

    The ototoxic effects of cisplatin were evaluated by otoacoustic emissions and evoked auditory responses. A transient otoacoustic emissions protocol indicated no significant ototoxic effects in rats treated intravenously with 7.5 mg/kg/week for 2-weeks. A chronic 6 week treatment (2.5 mg/kg /week) monitored by 2F1-F2 distortion product emissions presented significant S/N ratio alterations in a narrow range of frequencies (5.04- 5.66 kHz). An acute treatment of 15 mg/kg, using slow 30 min intra-peritoneal infusion , presented the highest DP and ABR alterations. The S/N ratio at the 2F1-F2 frequencies 6.34, 7.13, and 7.56 kHz was found significantly decreased and ABR latency measurements from 8K burst stimuli verified these alterations.

    ABSTRACT

    The paper presents various methodological approaches which can be used to detect ototoxic effects caused by the administration of various substances, using as an animal model the Sprague- Dawley rat. Electro-physiological data are also presented to show how the model behaves with potentially ototoxic (Hyaluronic acid) and initially-inert (hydroxy-propyl-methyl-cellulose) substances.
