杏仁超临界CO2萃取物抗UVA对成纤维细胞的损伤作用
杏仁 超临界CO2萃取 成纤维细胞 光老化
2012/11/1
探讨杏仁超临界CO2萃取物对UVA诱导的人皮肤成纤维细胞(ESF-1)损伤的保护作用及其作用机制。方法 用20 J·cm-2的UVA照射ESF-1细胞建立光老化细胞模型,以不同浓度杏仁超临界CO2萃取物处理光老化细胞,MTT法检测细胞活力,羟胺法检测细胞SOD活性,比色法检测GSH-Px活性,TBA法检测MDA含量,酶联免疫法检测TNF-α、IL-1β分泌量。结果 UVA照射ESF-1细胞后,细胞...
Protective effect of metallogluconates against UVA-induced cutaneous lesion in HR-1 hairless mice
skin UVA reactive oxygen species(ROS) inflammation
2009/4/1
UVA-induced reactive oxygen species (ROS) generation is well known to cause cutaneous lesion in the skin, therefore, it is important to prevent the skin from UV damage due to ROS generation. In 2000, ...
