【摘要】 目的:研究辛酸癸酸聚乙二醇甘油酯(labrasol,Lab),聚乙二醇硬脂酸酯15(solutol HS 15,Sol),二乙二醇单乙基醚(transcutol P,Trans)对芒果苷离体角膜透过率的影响。方法:采用离体扩散实验考察不同体积分数的3种渗透促进剂对芒果苷角膜透过率的影响。结果:Lab体积分数为1.0%,1.5%,2.0%,3.0%时,芒果苷的角膜表观渗透系数分别增加了1.80,3.27,3.41,4.76倍;Sol体积分数为0.2%,0.4%时,芒果苷的角膜表观渗透系数分别增加了1.98,3.07倍,与对照组相比均具有显著性差异(P<0.01),Trans体积分数为0.01%~0.03%时,芒果苷的角膜表观渗透系数并未增加。结论:Lab体积分数为1.0%~3.0%,Sol体积分数为0.2%~0.4%时,显著增加芒果苷的角膜表观渗透系数,而Trans体积分数为0.01%~0.03%时,不能增加芒果苷的角膜表观渗透系数。更多还原

【Abstract】 Objective: To investigate the effects of labrasol,solutol HS 15 and transcutol P on the corneal permeability of mangiferin in vitro.Method: The effects of three penetration enhancers on the corneal permeability of mangiferin were investigated in vitro by using isolated rabbit corneas.Result: The apparent Papp enhancements were increased 1.80,3.27,3.41 and 4.76-folds with Lab at 1.0%,1.5%,2.0% and 3.0%(P<0.01),respectively.The apparent Papp increased 1.98 and 3.07-folds with Sol at 0.2% and 0.4%(P<0.01),respectively,but reduced with 0.01%-0.03% Trans.Conclusion: The Papp value of mangiferin is significantly enhanced by 1.0%-3.0%Lab,0.2% and 0.4% Sol,however the Papp value of mangiferin is reduced by 0.01%-0.03% Trans.更多还原
