Fig 4. Evaluation of tracer recovery from the nasal turbinates of animals treated with daily doses of latanoprost over 3 days (4 animals treated with 0.1 mg/ml; 5 each with the other two doses).

Nasal turbinates were isolated 1 hour after ventricular tracer injection and between 7 and 9 hours after the final latanoprost dose was given intranasally; * = p<0.01 relative to control.
