Abstract
We investigated the effects of tyrosol (Tyr) on anterior chamber paracentesis (ACP)-induced anterior uveitis in beagle dogs, as determined by protein and prostaglandin E2 (PGE2) concentrations in the aqueous humor (AH). Tyr at a dose of 100 or 200 mg/kg or 2.2 mg/kg of carprofen as a positive control was administered orally twice daily from 2.5 days before paracentesis. The initial ACP was performed in one eye of individual dogs and 0.5 ml AH was aspirated. The secondary AH was collected 60 min later. Pretreatment with 200 mg/kg of Tyr and carprofen significantly decreased aqueous protein and PGE2 concentrations compared to the control group. Overall, these findings suggested that Tyr was useful for the management of canine anterior uveitis.
