Figure 5. Free radicals in the cochleae were detected after noise exposure.

Figure 5

(A, B) After noise exposure, the LPO and MDA levels of the normal saline group were significantly higher than the hydrogen-saturated saline group. (C) Immediately after noise exposure, the content of ·OH in the cochleae of the normal saline group was significantly higher than the hydrogen-saturated saline group. The difference was abolished by the 7th day after noise exposure. D0/D7+HS: immediately/7days after noise exposure of hydrogen-saturated saline group. D0/D7+NS: immediately/7days after noise exposure of normal saline group. *P<0.05, **P<0.01: vs. control. #P<0.05, ##P<0.01: D0+NS vs. D0+HS. ΔP<0.05, ΔΔP<0.01: D7+NS vs. D7+HS.
