In our previous work, we discovered a fine structure corresponding to the fingerprint pattern in the stratum corneum and surrounding area from observation of OCT images, and developed a method which detects the light from the light source goes through a fine structure and create grayscale images corresponding to a fingerprint pattern. In this paper, to clarify the origins of the greyscale image, we propose a simple simulated model of the fine structure of different light scattering properties alternately arranged in the epidermis of finger skin. We calculated the light intensity distribution via a Monte Carlo simulation of light scattering with two parameter sets at 640 nm. We found that the light passing through this model created a greyscale image that corresponded to the epidermis structure.","PeriodicalId":19350,"journal":{"name":"Nippon Laser Igakkaishi","volume":"59 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86581853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Porphyrin compounds have been known as not only a photosensitizer but also radiosensitizer. In clinical neurosurgery, 5-aminolevulinic acid (ALA) is available for intraoperative fluorescence marker for malignant gliomas. Recently, combination therapy using 5ALA and ionizing irradiation for malignant tumors have been investigated. 5-ALA can highly accumulate protoporphyrin IX (PpIX) in mitochondria of tumor cells via the heme biosynthesis. PpIX can induce oxidative stress on mitochondria of tumor cells under the ionizing irradiation exposure.
