The effect of trioxsalen bath PUVA therapy on nonimmunologic immediate contact reactions (NIICRs) induced by benzoic acid (BA) and methyl nicotinate (MN) was studied in 12 dermatologic patients. One half of the back skin was covered with a cloth before each of ten irradiations on subsequent days.
Systemic effects of ultraviolet irradiation B (UVB) and ultraviolet irradiation A (UVA) on non-immunologic immediate contact reactions (NIICRs) induced by benzoic acid (BA) and methyl nicotinate (MN) were studied in healthy volunteers. NIICR tests with four concentrations of BA and MN in white
Effects of infra-red A (IRA) (600-2000 nm) and 1064 nm laser irradiation on non-immunologic immediate contact reactions (NIICRs) induced by benzoic acid (BA) and methyl nicotinate (MN) were studied. Five concentrations of BA and MN in petrolatum were tested, on two subsequent days, without occlusion
The effects of 3 topical applications of non-steroidal anti-inflammatory drugs (NSAIDs), diclofenac 1%, naproxene 10% and salicylic acid 5% in gel vehicles, on immediate contact reactions to 500 mM benzoic acid, 500 mM cinnamic aldehyde, 50 mM methyl nicotinate, all in pet., and 14.1 M (100%)
The suitability of the guinea pig for studies on nonimmunologic contact urticaria (NICU) was investigated. Groups of five, female Hartley guinea pigs were challenged by applying 50 microliters of various concentrations of human NICU agents, benzoic acid (BA), sorbic acid (SA), cinnamic acid (CA),
To investigate the mechanisms of non-immunologic contact urticaria (NICU), the effect of 120 mg of terfenadine (H1-antagonist) on contact reactions to methyl nicotinate, diethyl fumarate, benzoic acid, cinnamic acid, cinnamic aldehyde and dimethyl sulfoxide was studied in 20 subjects. Erythema and
In the present study we examined the effects of chlorpheniramine and ranitidine, indomethacin, BW755C (an inhibitor of cyclo-oxygenase and lipo-oxygenase enzymes of arachidonic acid metabolism), dexamethasone, and capsaicin on nonimmunologic contact urticaria (NICU) induced in the guinea pig ear by
Complex chemical mixtures at hazardous waste sites can potentially consist of a marker chemical and several other chemicals, each of which can have different modulating actions on the dermatotoxicity of the marker chemical and/or other components in the mixture. A total of 16 mixtures, consisting of
To investigate the mechanisms of non-immunologic contact urticaria (NICU), the effects of 1g + 1g of acetylsalicylic acid (ASA) on contact reactions to methyl nicotinate, diethyl fumarate, benzoic acid, cinnamic acid, cinnamic aldehyde and dimethyl sulfoxide were studied in 21 test subjects.
