Abstract
Background and Purpose: Noise in high intensity is one of the major physical stressors. The aim of this study was to determine the effect of stress of threshold limit value of noise with shrill and bass frequencies on antioxidation and lipid peroxidation variations of liver tissue of rabbit. Methods and Materials: This experimental study was carried out on 18 male white New Zealand rabbits at Tarbiat Modarres University in 2004. Rabbits were randomly divided into three groups: Control Group (unexposed to noise) Group 2 exposed to noise (85 dB SPL< 250-3540Hz 8 h/day 96 h) and Group 3 exposed to noise (3540Hz-20kHz 85 dB SPL 8 h/day for 96h 12 days). The obtained data were analyzed in SPSS. One-way ANOVA and post hoc Tukey test were used for comparing means across the groups; differences at P
