| Abstract |
|
The effects of topical sodium-hyaluronan (Na-HA)on the epithelial healing and aqueous compositions were examined in the repair process of experimen-tal corneal alkali wounds.Corneal alkali wounds were produced in one eye of each rabbit by applying a 5.5 mmround filter paper soaked in 1N NaOH onto the central cornea for 60 seconds.Then the eyes were treated topically with either 1%Na-HA (the treatment group)or a phosphate buffered saline (PBS) (the control group)4 times per day.The epithelial healing was assessed using a quantitative method and the changes of the concentration of ascorbic acid and glucose in aqueous were evaluated.The initial epithelial healing rate was similar between 1%Na-HA treated and control groups and the later healing was enhanced in the treated group but statistically insignificant.The concentrations of ascorbic acid and glucose in aqueous humor are not statistically different in the early phase, but ascorbic acid concentration in later healing phase was higher in the treated group when compared with the control group.The present findings in dicate that topical-ly applied 1%Na-HA affects late epithelial healing and ascorbic acid concentration in aqueous humor during the repair process after corneal alkali wounds. |
