“Animals treated with magnesium after the 176-dB SPL exposure had a significant reduction in hair cell loss in the basal region.”
“The threshold shifts of the 170-dB SPL group that received magnesium were significantly lower than those of controls after 2 and 7 days of recovery, but no significant difference was evidenced at 14 days in this group, nor at any time in the 176-dB SPL group.”
