Fig 3. Probucol ameliorates apoptosis in hyperoxic lung injury.

Fig 3

(A-D) The effect of probucol on TUNEL staining. (A) No positive signals for TUNEL were observed in lung tissues of room-air-exposed mice treated with probucol. (B) There were some TUNEL-positive cells (arrows in F) in the lung tissues of hyperoxia-exposed mice. (C) Probucol treatment decreased the number of TUNEL-positive cells in hyperoxia-exposed mice. (D) Quantitative result of the number of TUNEL-positive cells in lung tissues. Original magnifications: ×200. Data are shown as the mean ± SEM from four mice in each group. **p < 0.01.
