ABSTRACT
BACKGROUND AND

OBJECTIVES:

It has been recognized that salicylate induces ototoxicity in animals and humans. Many studies have been done to identify the mechanisms of ototoxicity of salicylate with histopathological, biochemical and electrophysiological methods. Among these methods, the electrophysiological method is useful for clinical diagnosis and evaluation of therapeutic effect. The studies reported here were aimed at performing electrophysiological effects of salicylate by using Auditory Brainstem Response (ABR) and Electrocochleography (EcoG) through non-invasive approach. MATERIAL AND

METHODS:

Auditory brainstem response and electrocochleogram were observed by non-invasive approaching method after the intraperitoneal injection of 450 mg/kg of lysine salicylate on 10 ears of 5 guinea pigs.

RESULTS:

The threshold shifting of ABR and ECoG were less than 10 dB. The latency of ABR waves and Summating Potential were increased after salicylate was administered especially at low intensity sound stimulation.

CONCLUSION:

The latency of ABR wave and SP would be useful in diagnosing ototoxicity and evaluating the therapeutic effect in ototoxic patients.
