Ferguson J, Johnson BE: Retinoid associated phototoxicity
Topical nonsteroidal antiinflammatory drugs: allergic and photoallergic contact dermatitis and phototoxicity
The real question has been, is phototoxicity
simply a laboratory artifact or is it important in the field?
2:30 PHOTOCHEMISTRY AND PHOTOTOXICITY
Although the dangers associated with exposure to theatre lights at laparotomy have been reported (5,6), the possibility of phototoxicity
during laparoscopy has never been explored.
Many plant substances when exposed to UV or visible light exhibit phototoxicity
and are referred to as phototoxins or photosensitizers (18).
The objectives of this article are to examine factors that propagate skin phototoxicity
(photoaging) and look at natural ways to combat this major public health concern.
In 2000, the compound was referred to the National Institutes of Health's National Toxicology Program (NTP) for phototoxicity
and photocar-cinogenicity testing, along with other common ingredients such as alpha- and beta-hydroxy acids, aloe vera, and nanoscale titanium dioxide and zinc oxide.
These data show a lack of phototoxicity
in the irradiated cells because no differences were observed compared with the non irradiated cells.
Detailed articles cover topics such as spectral properties, brightness and maturation, phototoxicity
and photostability of the various fluorescent proteins and offer practical advice on their applications in live cell imaging.
In vivo protective effect of B-carotene against psoralen phototoxicity
Episkin only tests for skin corrosion and irritation, but there are around 30 validated alternatives to animal testing for other tests such as penetration and phototoxicity
