The Dp+Povidone iodine (iodopovidone) (PVP-I) group has the second highest average score from day 13 to the end of the experimental period. The Dp+Povidone iodine and Dp+Et-OH groups also show a significantly increase in eosinophil count compare with the control group (p<0.05 and p<0.001, respectively). However, the eosinophil count does not significantly differ among the Dp+Povidone iodine (PVP-I), Dp+CHG, and Dp+vehicle groups.
