概括

防晒的选择通过改变Protoporphyrin IX (PpIX) 激活,显著影响日光光动力学疗法 (DL-PDT) 的疗效. 一些有机过器阻断了关键波长,降低了治疗的有效性.

科学领域:

照相医疗 (photomedicine) 是一种医学技术.
皮肤病学皮肤病学
摄影化学的使用.

背景情况:

日光光动力学疗法 (DL-PDT) 需要防晒,以防止暴露在光线下的晒伤.
避免使用无机过器,因为它们会阻所需的可见光.
防晒中的有机过器可以显著吸收Protoporphyrin IX (PpIX) 波长.

研究的目的:

调查不同的防晒如何影响DL-PDT的PpIX激活.
分析防晒的光谱透射率及其对PpIX吸收的影响.

主要方法:

测量了各种临床防晒的光谱透射率.
使用skydome辐射和防晒数据计算PpIX吸收率.
为分析划分了五个光谱区域 (R-I到R-V).

主要成果:

防晒在关键的R-I区域大大降低了PpIX激活 (28%至8%从没有防晒的85%降至8%).
在所有测试的防晒中,在R-II到R-V区域观察到较低的激活水平 (≤5%).
激活效率的变化取决于防晒的过器吸收光谱.

结论:

在PpIX光谱中,防晒的吸收方式存在显著差异.
有机过器的成分,而不是无机过器的存在,决定了防晒的影响.
仔细选择防晒对于优化PpIX激活和DL-PDT疗效至关重要.

关键词:

UV–Vis Spectrometers

UV–Vis Spectrometers

The absorbance of UV and visible (UV–visible) radiations is measured using a UV–visible spectrophotometer. Deuterium lamps, which emit UV radiation, and tungsten lamps, which produce radiation in the visible region, are used as light sources in UV–visible spectrophotometers. A monochromator or prism is used for diffraction grating, i.e., to split the incoming radiation into different wavelengths. A system of slits is used to focus the desired wavelength on the sample cell.

Spectrophotometry: Introduction

Spectrophotometry: Introduction

Spectrophotometry is the quantitative measurement of the absorption, reflection, diffraction, or transmission of electromagnetic radiation through a material as a function of the intensity and wavelength of the radiation. A spectrophotometer is a device used to measure the change in the radiation intensity caused by its interaction with the material.
The essential components of a spectrophotometer include a source of electromagnetic radiation, a slot for placing a material to be analyzed, and a...
