摘要

背景:用 "黑光 "照明的房间(材料与结果:将五组四只小鼠分别置于不同的白光、紫光和黑暗环境中,利用休息-活动周期测量昼夜节律,分析它们的昼夜节律。此外,还对实验动物进行了视网膜电图记录和视网膜结构分析:我们的研究表明,小鼠在紫光照射下呈现正常的昼夜节律活动,不仅在白光下休息,而且在紫光照射下也休息。然而,通过视网膜电图测量,小鼠在接触紫光后视网膜电反应下降。然而,在不同的光照条件下,动物视网膜的结构没有发生变化:结论:紫外线能引起小鼠昼夜节律性的休息-活动节律,但会改变它们的视觉功能,尽管在短时间的紫外线照射后没有观察到结构变化。

Violet Light Effects on the Circadian Rest-Activity Rhythm and the Visual System.

Background: Rooms illuminated by "black light" (<400 nm wavelength) has become popular, but there is not enough scientific evidence to support its implementation. This study aims to assess the effects of violet light (392 nm) on the circadian rest-activity rhythm and the visual system through animal experimentation.

Materials and results: Five groups of four mice were exposed to different white light, violet light, and dark periods, and their circadian rhythm was analyzed by measuring the circadian period using rest-activity cycles. Electroretinographic recordings and structural analysis of the retina were also performed on experimental animals.

Results: Our study demonstrates that mice present normal circadian activity during exposure to violet light, taking rest not only under white light but under violet lighting periods. However, mice suffered a decrease in electrical retinal response after exposure to violet light as measured by electroretinography. Nevertheless, no structural changes were observed in the retinas of the animals under different lighting conditions.

Conclusions: Violet light elicits circadian rest-activity rhythm in mice but alters their visual function, although no structural changes are observed after short periods of violet light exposure.
