An animal model of experimental vestibular dysfunction by intratympanically injecting arsanilic acid in mice

  • Received Date: 2008-05-26
  • Objective: To establish a convenient and feasible animal model of vestibular dysfunction for pharmacodynamic study in mice. Methods: Both inner ears of the animals were intratympanically injected with 100 mg/mL solution of arsanilic acid for 0.05 mL. 3 days later,vestibular function was assessed by air righting reflex and contact righting reflex,as well as the head tilt and swimming behavior. Results: Correct landings rates of air righting reflex were decreased;time of contact righting reflex was prolonged;scores of head tilt and swimming behavior were higher than control. Conclusion: It is a convenient and feasible model of experimental vestibular dysfunction with injections of arsanilic acid in the inner ears of mice for research on pharmacodynamics of prophylactic drug for motion sickness and vertigo.
