UV irradiation (365 nm) of air-saturated methanol solutions of 20 drugs absorbing in the 300--400 nm region gave rise to oxygen uptake, as determined with a polarographic oxygen electrode. The drugs were tested for photosensitizing capability by either a Type I (free radical) or a Type II (single molecular oxygen) mechanism.

Normal human skin is photosensitive in that it reddens following acute sunlight exposure and tans and thickens following chronic sunlight exposure. Skin cancer, particularly nonmelanoma skin cancer, is also a consequence of high cumulative sun exposure in genetically predisposed normal individuals (predominantly those with fair skin)....

Photosensitivity to Oxytetracycline
Annals of Internal Medicine, 1963Excerpt Photosensitivity to oxytetracycline (Terramycin®) is rare. Shwachman and Schuster (1) reported that 3 per cent of 300 children treated with chlortetracycline (Aureomycin®) and oxytetracycli...

The Diagnosis of Photosensitivity
Archives of Dermatology, 2000Many photosensitive patients are seen for consultation when they have no lesions, so a detailed history is important. The differential diagnosis is based on the age at which the symptoms first occurred. The striking symptoms and signs are discussed, and advice is given on which additional investigations are necessary and when phototesting must be ...

During a study of photodynamic action in white mice we became aware of the effect of heat on this process. A review of the literature revealed that little work had been done regarding this problem, and available reports provided conflicting results. In an effort to resolve these differences, we decided to study the influence of heat on the photodynamic

Photosensitivity in the elderly
British Journal of Dermatology, 1990Photosensitivity to drugs and chemicals in the elderly is more prevalent due to more frequent use of medications. Phototoxic reactions to common, orally administered drugs such as diuretics, cardiac agents and antidiabetics may occur and the reactions may be remedied by discontinuing drug therapy.

To the Editor:— Dr. Stephan Epstein's contribution, "Photoallergic Contact Dermatitis" ( 194 :1016, 1965) establishes the photosensitizing properties of Lifebuoy soap. A similar study has been conducted in the Louisville, Ky, area, with different conclusions regarding the photosensitizing agent in the soap. There are three different Lifebuoys: white,

Employing photodestructible surfactants in gelatin-based aqueous gels presents novel possibilities for controlling colloidal and aggregation properties of surfactant gelatin complexes. Light-triggered breakdown of the gelatin-bound photosurfactant aggregates causes dramatic changes in viscosity and aggregation.
