Photodynamic diagnosis (PDD) is a form of cancer detection based on the administration of an exogenous photo-activated compound that accumulates in malignant cells, followed by appropriate photo irradiation. The authors describe a spectroscopic study of 5-aminolevulinic acid (5-ALA)-generated photosensitizer protoporphyrin IX (PpIX) fluorescence in human(More)
BACKGROUND Oral leukoplakias (LP) are the most frequent types of oral pre-cancerous lesions, but there is no accurate assessment of this malignant transformation or even genetic diagnosis of the oral epithelial dysplasia. We need to identify the new genetic diagnosis system of the epithelial dysplasia. METHODS Oligonucleotide microarray was used to(More)

Photodynamic diagnosis (PDD) is a form of cancer detection based on the administration of an exogenous photoactivated compound that accumulates in malignant cells, followed by appropriate photo-irradiation. 5-aminolevulinic acid (5-ALA), which is one of these compounds, is a prodrug of the photosensitizer protoporphyrin IX (PpIX). This report describes a(More)
