The Effect of Hydration on Distortion Product Otoacoustic Emission Values in Rats

Abstract

Objectives: This study aimed to evaluate the changes that would appear in the inner ear acoustic characteristics of dehydrated and overhydrated rats through distortion product otoacoustic emission (DPOAE).
Materials and Methods: The study was conducted with 24 male Sprague Dawey rats. After otoacoustic examinations of the rats were made under general anesthesia, their blood samples were taken, weights were measured. Then, the rats were divided into three groups as dehydration group, overhydration group and control group. Distortion product otoacoustic emission measurements were repeated after 72 hours, and the results were compared.
Results: There were no significant differences in the first measurements between three groups in terms of (p>0.05). Weight and osmolarity values differed significantly in the dehydration and overhydration groups following the fluid intake change (p<0.05), but in the control group (p> 0.05). There was a significant decrease in the SNRs at 4004 Hz, 7998 Hz and 9854 Hz frequencies of the overhydration group (p<0.05). On the other hand, there were no significant changes in the DPOAE SNR dB values of the dehydration and control groups (p>0.05).
Conclusions: The results of this study indicate that overhydration in rats may change DPOAE values.
