OBJECTIVE To evaluate the therapeutic effects of combined 5-aminolevulinic acid (ALA) and photodynamic therapy (PDT) on genital warts and the safety. METHODS One hundred ten patients with genital warts who were treated in our hospital from June 2013 to October 2014 were selected. The warts and affected parts were disinfected with benzalkonium bromide solution, and the warts were covered with ...

OBJECT Accumulation of protoporphyrin IX (PPIX) in malignant gliomas is induced by 5-aminolevulinic acid (5-ALA). Because PPIX is a potent photosensitizer, the authors sought to discover whether its accumulation might be exploited for use in photoirradiation therapy of experimental brain tumors, without injuring normal or edematous brain. METHODS Thirty rats underwent craniotomy and were rand...

The early, de-embryonated chick blastoderm, cultured in vitro, closely simulates a phased culture of erythroid cells. This fact permits the study of hemoglobin synthesis from colorless erythroblast precursor cells to fully hemoglobinated erythrocytes. When b-aminolevulinic acid is added to colorless blastoderms, thereby by-passing &aminolevulinic acid synthetase, copious amounts of porphyrins, ...

BACKGROUND Early detection of premalignant/malignant lesions in the oral cavity can certainly improve the patient's prognosis. This study presents fluorescence imaging with the topical application of 5-aminolevulinic as a way to improve detection of various oral tissue pathologies. This procedure depends mainly on comparing the intensity of red and green fluorescence emitted from tissues during...
