Experimental studies on phototoxic and photoallergic reaction by the skin window technique. 1979

K Nishioka, and H Fujita

The differentiation of photoallergic contact dermatitis by 3,3', 4', 5-tetra-chlorosalicylanilide from phototoxic contact dermatitis by 8-MOP in guinea pigs was studied by skin window technique. Based upon the results, it may be concluded that the photoallergic reaction can be differentiated from phototoxic reaction by the appearing pattern of basophilic leukocytes.

D008730	Methoxsalen	A naturally occurring furocoumarin compound found in several species of plants, including Psoralea corylifolia. It is a photoactive substance that forms DNA ADDUCTS in the presence of ultraviolet A irradiation.	8-Methoxypsoralen,Ammoidin,Xanthotoxin,8-MOP,Deltasoralen,Dermox,Geroxalen,Meladinina,Meladinine,Meloxine,Methoxa-Dome,Méladinine,Oxsoralen,Oxsoralen-Ultra,Puvalen,Ultramop,8 MOP,8 Methoxypsoralen,8MOP,Methoxa Dome,Oxsoralen Ultra
D010787	Photosensitivity Disorders	Abnormal responses to sunlight or artificial light due to extreme reactivity of light-absorbing molecules in tissues. It refers almost exclusively to skin photosensitivity, including sunburn, reactions due to repeated prolonged exposure in the absence of photosensitizing factors, and reactions requiring photosensitizing factors such as photosensitizing agents and certain diseases. With restricted reference to skin tissue, it does not include photosensitivity of the eye to light, as in photophobia or photosensitive epilepsy.

D006168	Guinea Pigs	A common name used for the genus Cavia. The most common species is Cavia porcellus which is the domesticated guinea pig used for pets and biomedical research.	Cavia,Cavia porcellus,Guinea Pig,Pig, Guinea,Pigs, Guinea
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D012458	Salicylanilides	2-Hydroxy-N-phenylbenzamides. N-phenyl substituted salicylamides. Derivatives have been used as fungicides, anti-mildew agents and topical antifungal agents. In concentrated form may cause irritation of skin and mucous membranes.	N-Phenylsalicylamides,N Phenylsalicylamides
D012884	Skin Window Technique	A technique to study CELL MIGRATION in the INFLAMMATION process or during immune reactions. After an area on the skin is abraded, the movement of cells in the area is followed via microscopic observation of the exudate through a coverslip or tissue culture chamber placed over the area.

D014466	Ultraviolet Rays	That portion of the electromagnetic spectrum immediately below the visible range and extending into the x-ray frequencies. The longer wavelengths (near-UV or biotic or vital rays) are necessary for the endogenous synthesis of vitamin D and are also called antirachitic rays; the shorter, ionizing wavelengths (far-UV or abiotic or extravital rays) are viricidal, bactericidal, mutagenic, and carcinogenic and are used as disinfectants.
