Abstract: Objective To determine the permeation profile of 125I-α-cobratoxin across different animals'nasal mucosa and the enhancement of borneol. Methods The rabbits、dogs and goats was selected as model animals, radioactivity (count per minute, cpm)as index, and a method called permeation of nasal mucosa in vitro was adopted,together with repeated cycle technique in situ to compare the permeation profile of Nt across different animals'nasal mucosa in vitro in order to confirm the permeation of these animals and the effect of borneol. Results Nt could penetrate the nasal mucosa of different animals and be absorbed, but the amount was low. However, the absorption could be enhanced under the help of borneol. Conclusion Borneol could enhance the absorption of Nt arcoss the nasal mucosa.
