摘要
目的 :研究氮酮对蟾酥中蟾毒内酯类成分体外渗透动力学的影响。方法 :以裸鼠皮肤为实验屏障 ,研究氮酮浓度分别为 0 % ,2 % ,4% ,6 % ,8% ,1 0 %时蟾毒内酯的透皮速率常数。结果 :氮酮浓度为 0 % ,2 % ,4% ,6 % ,8% ,1 0 %时蟾毒内酯的渗透速率常数分别为 81 .2 5 ,1 1 4 .92 ,1 69.63 ,1 96 .31 ,2 0 8.2 7,2 61 .35(μg/cm2 ·h)。结论 :氮酮可以促进蟾毒内酯的透皮吸收 ,在实验浓度范围内 ,氮酮浓度为 1 0 %时有最大的透皮速率常数。
Objective: To study the effect of Azone on the transdermal kinetics of Resibufogenin from toad venom. Methods: The transdermal constants of Resibufogenin var hairless mice skin are determined with various concentration of Azone as transdermal enhancers. Results: The transdermal constants are 81.25, 114.92, 169.63 , 196.31, 208.27, 261.35 (μg/cm 2·h) while the concentration of Azone are 0%, 2%, 4%, 6%, 8%, 10%, respectively. Conclusion: Azone can enhance Resibufogenin penetrate skin and the optimum concentration of Azone is 10%.
