Abstract

The broadband absorption coefficient spectrum of the rabbit lung presents some particular characteristics that allow the identification of the chromophores in this tissue. By performing a weighted combination of the absorption spectra of water, hemoglobin, DNA, proteins and the pigments melanin and lipofuscin, it was possible to obtain a good match to the experimental absorption spectrum of the lung. Such reconstruction provided reasonable information about the contents of the tissue components in the lung tissue, and allowed to identify a similar accumulation of melanin and lipofuscin.

分析兔肺的实验吸收光谱并确定其成分。
兔肺的宽带吸收系数光谱呈现出一些特殊的特征,可用于识别该组织中的发色团。通过对水、血红蛋白、DNA、蛋白质以及色素黑色素和脂褐素的吸收光谱进行加权组合,可以获得与肺实验吸收光谱的良好匹配。这种重建提供了有关肺组织中组织成分含量的合理信息,并可确定黑色素和脂褐素的类似积累。

期刊介绍: The first international journal dedicated to publishing reviews and original articles from this exciting field, the Journal of Biophotonics covers the broad range of research on interactions between light and biological material. The journal offers a platform where the physicist communicates with the biologist and where the clinical practitioner learns about the latest tools for the diagnosis of diseases. As such, the journal is highly interdisciplinary, publishing cutting edge research in the fields of life sciences, medicine, physics, chemistry, and engineering. The coverage extends from fundamental research to specific developments, while also including the latest applications.
