Abstract

Ecabet sodium (ES) is currently applied to some clinical gastrointestinal disease primarily by the inhibition of the ROS production. In this study, the protective role of ES was evaluated against the neomycin-induced hair cell loss using zebrafish experimental animal model. Zebrafish larvae (5-7 dpf), were treated with each of the following concentrations of ES: 5, 10, 20, 40, and 80 μg/mL for 1 h, followed by 125 μM neomycin for 1 h. The positive control group was established by 125 μM neomycin-only treatment (1 h) and the negative control group with no additional chemicals was also established. Hair cells inside four neuromasts (SO1, SO2, O1, OC1) were assessed using fluorescence microscopy (n=10). Hair cell survival was calculated as the mean number of viable hair cells for each group. Apoptosis and mitochondrial damage were investigated using special staining (TUNEL and DASPEI assay, respectively), and compared among groups. Ultrastructural changes were evaluated using scanning electron microscopy. Pre-treatment group with ES increased the mean number of viable hair cells as a dose-dependent manner achieving almost same number of viable hair cells with 40 μM/ml ES treatment (12.98±2.59 cells) comparing to that of the negative control group (14.15±1.39 cells, p=0.72) and significantly more number of viable hair cells than that of the positive control group (7.45±0.91 cells, p
