    • Abstract
  • This study was designed to investigate the therapeutic effect of anti-inflammatory tripeptide KdPT on ophthalmoxerosis. Male BALB/c mice, 8-week old, were treated with 0.2% benzalkonium chloride solution to establish the ophthalmoxerosis model. Four weeks after modeling, the mice were randomly divided into control group, positive group and the low, medium, high dose groups of KdPT. Each group was given normal saline, artificial tears and 1, 10, 100 μg/mL KdPT, respectively. After 3, 5, 7, 10 and 14 days of treatment, the morphology of the eye surface was observed, and the fluorescein sodium staining score was performed. The amount of tear secretion was measured by phenol red cotton thread and the right corneas were taken out for histopathological analysis after 14 days of treatment. Data showed that there was no significant abnormality in general state and the weight of mice in each group at each time point of treatment. After 14 days of treatment, KdPT can promote the secretion of tear, repair the damaged corneal epithelium, and showed a significant therapeutic effect on ophthalmoxerosis in mice. Based on the data, it is possible for KdPT to be developed as a novel drug for ophthalmoxerosis.
