Summary

该协议描述了对小鼠紫外线B暴露的全身和局部皮肤影响的研究。

Transcript

我们正在研究皮肤暴露于低剂量 UVB 辐射的全身影响,特别是低于引起红斑的水平。我们的方案将允许了解低剂量 UVB 暴露的全身影响,而不仅仅是对皮肤的直接或局部影响。我们的方法非常模仿长期低度暴露于红斑水平以下的 UVB。因此,我们能够研究 UVB 的内源性影响。

[旁白]首先,将麻醉的小鼠放在工作平台上,剃掉其背部区域的 50% 至 60%。使用脱毛膏去除皮毛后,将鼠标放入干净、干燥的带笼子垫料的恢复笼中。让老鼠在家庭笼子里休息,随意提供食物和水。首先,请穿长袖衬衫、裤子、实验室外套、封闭式鞋子、双层手套和面罩,以确保人身安全。在生物罩内进行紫外线 B 照射,降低 10 毫米有机玻璃盖并放置保护屏。将紫外线 B 灯放在透明有机玻璃室上。打开紫外线 B lamp,让它运行直到强度稳定。然后打开紫外线 X 辐射计,配备紫外线 B 测量头来监测强度。将清洁后的曝光室放入具有两个腔室的透明有机玻璃室内,同时打开或关闭紫外线灯以进行相应的紫外线或模拟曝光。使用计算器确定将鼠标暴露在所需紫外线 B 强度下所需的时间。将鼠标从家庭笼转移到曝光室,以达到所需的曝光时间。将小鼠暴露于每平方厘米50毫焦耳的紫外线B剂量下,这是亚红斑剂量。为了验证辐射效率,请使用真皮分光光度计测量耳朵和尾巴的色素沉着。通过用干净的普通白纸设置基线来校准分光光度计设备。校准完成后,将测量传感器放在鼠标的耳朵或尾巴上,并记录黑色素强度读数。与对照组相比,在暴露于紫外线 B 辐射的雄性和雌性小鼠中观察到黑色素水平在 4 周内逐渐显着增加,证实了皮肤色素沉着的成功诱导。
