纳米氧化钛对紫外线所致皮肤损伤的作用
首发时间:2004-05-07
摘要:目的:评价纳米氧化钛在紫外线辐射(ultraviolet radiation, UVR)所致皮肤损伤中的作用。方法:正常皮肤在纳米氧化钛和另一种市售防晒药膏(以下简称“药物”)的干预下经设计剂量紫外线照射后,将各组样本比较。结果:纳米氧化钛干预组与自身对照组比较,豚鼠皮肤外观及各层组织未见明显差异;经过同样剂量紫外线照射,药物对照组(涂一市售品牌防晒药膏组)皮肤外观及各层皮组织结构均可见显著改变。结论:研究初步表明纳米氧化钛具有较强的抗紫外线所致皮肤损伤特性。

Estimation on protective effect of nano-TiO2 skin damage induced by UVR
Abstract:Objective: To Estimate on the protection effect of titanium oxide on skin damage induced by ultraviolet radiation. Methods: After the normal skin in guinea pig under the intervene of nano-TiO2 was irradiated with over-dose of ultraviolet rays (UVB and UVA), the samples in every group were matched and compared. Results: The skin tissue in the nano-TiO2 intervene group irradiated by ultraviolet rays didn’t change obviously as compared with that in the self-control group. But, the damage skin tissue in the control group irradiated by ultraviolet did change significantly as compared with that in the nano-TiO2 intervene group. Conclusion: nano-TiO2 is a good material to protect the skin from damage effect by ultraviolet radiation.
Keywords: ultraviolet radiation nano-structured materials titanium oxide skin damnification
