Chronic Lead Exposure Results in Auditory Deficits and Disruption of Hair Cells in Postweaning Rats

<div>Changes in cochlea GSH content (a), CAT activity (b), SOD activity (c), GSH-Px activity (d), GR activity (e), and MDA level (index of lipid peroxidation) (f) following chronic lead exposure in rats. GSH: nmoles/mg protein; MDA: nmoles/mg protein; enzyme activities (CAT, SOD, GSH-Px, and GR) are expressed as units/mg protein.
