Archives of Pharmacal Research, 1999
Melatonin (MLT), N-acetyl-5-methoxytryptamine, is mainly secreted by the pineal gland. The ultraviolet (UV), infrared (IR) and 1H-NMR spectra of irradiated and non-irradiated MLT were measured, and phototoxicity tests of MLT, anthracene (positive control) and sodium lauryl sulfate (SLS, negative control) were performed.

Phototoxicity and photoallergy
Seminars in Cutaneous Medicine and Surgery, 1999Photosensitivity may be phototoxic or photoallergic. Phototoxicity is much more common. There are 2 types of phototoxicity: photodynamic, which requires oxygen, and nonphotodynamic, which does not. Reactions induced by porphyrin molecules, coal tar derivatives, and many drugs are photodynamic.

Ocular fluorescein phototoxicity
Applied Optics, 1987Fluorescein angiography is one of the most commonly used diagnostic techniques in modern ophthalmology. Prior to this study, recommendations on the phototoxicity of this technique were based on light levels alone (i.e., without fluorescein present). Using a rabbit model to demonstrate retinal damage, intravenous sodium fluorescein was found to reduce ...

Phototoxicity of olaquindox in the rat
Research in Veterinary Science, 1990Because of its photoallergic properties quindoxin, a growth promoting feed additive used for example in cattle raising, has been taken off the market. Recently, it appeared that the quindoxin derived olaquindox (OLAQ), used for the same purpose, also produces these light-induced side effects.

JAMA, 1979
Ignorance of phototoxicity by the general biomedical community constitutes a health hazard. Certain food colorants and dyes proposed for use in angiography produce lethal effects in cells and whole organisms on light exposure but not in the dark. Yet light-relatedness is usually neglected in toxicity studies.

Phototoxicity of Shalimar Perfume
Archives of Dermatology, 1966Application of Shalimar perfume to the skin denuded of stratum corneum, followed by irradiation by the proper ultraviolet energy, produced intense phototoxic reactions in ten out of ten normal patients tested.

Phototoxicity and photoallergy in man
Journal of the American Academy of Dermatology, 1983Photosensitivity is the broad term used to denote adverse reactions to the sun. These reactions may be phototoxic or photoallergic. Phototoxic reactions are much more common than photoallergic reactions. Phototoxic reactions may be photodynamic or nonphotodynamic in nature, the primary difference being that photodynamic reactions require oxygen ...
