摘要:

目的 采用三维人重组角膜模型BioOcular^TM和现行的兔眼刺激Daize法，对市面常见的不同配方洗发水的眼刺激性进行评价与比较。方法 体外眼刺激实验（OECD指导原则492）采用人重组眼角膜上皮模型和兔眼刺激法对8种不同品牌洗发水的眼刺激性进行评价研究。结果 采用皮肤模型的眼刺激法对8种洗发水有无刺激性的区分结果与兔眼刺激法基本一致。2种方法相关系数r绝对值达到0.955，具有很好的相关性。结论 与兔眼刺激法相比，人重组眼角膜上皮模型实验所需的周期短、试验步骤相对简便、检测结果相对更加客观，人源重组组织与人眼角膜上皮更为接近，是一种值得推荐的眼刺激替代检测方法。

Abstract:

OBJECTIVE To evaluate eye irritation potential of different shampoos using Draize assay in vivo and eye irritation test with human cornea-like epithelial tissue model BioOcular^TM in vitro respectively. METHODS In terms of OECD Guide Line 492, 8 kinds of different shampoos were tested both in Draize assay in vivo and eye irritation test with reconstructed human cornea-like epithelial tissue model BioOcular^TM in vitro. RESULTS There was a good relativity of eye irritation potential for these two methods. And correlation coefficent score for these two methods was 0.955. CONCLUSION Compared with Draize assay in vivo human cornea-like epithelial tissue model BioOcular^TM in vitro needs short period, simple steps, and the results are relatively objective. It is workable to use 3D human cornea-like epithelial tissue model BioOcular^TM in vitro for eye irritation test partly instead of Draize assay.
