Contact allergy to and allergic contact dermatitis from methyldibromo glutaronitrile (MDBGN) have frequently been reported. This study was initiated to help determine the optimal patch test preparation for MDBGN. In 51 patients with a doubtful or a positive patch test reaction to at least 1 of 4 test preparations with MDBGN in petrolatum at 1.0% w/w, 0.5%, 0.3% and 0.1%, a repeated open applica...
Atranol and chloroatranol are strong contact allergens in oak moss absolute, a lichen extract used in perfumery. Fifteen subjects with contact allergy to oak moss absolute underwent a repeated open application test (ROAT) using solutions of an untreated oak moss absolute (sample A) and an oak moss absolute with reduced content of atranol and chloroatranol (sample B). All subjects were in additi...
Based on the nucleotide sequence of a mouse prostaglandin-specific transporter (mOAT-PG), we identified a rat homolog (rOAT-PG) which shares 80% identity with mOAT-PG in a deduced amino acid sequence. rOAT-PG transports PGE(2) and colocalizes with 15-hydroxyprostaglandin dehydrogenase (15-PGDH), a metabolic enzyme for PGs, in proximal tubules, suggesting that rOAT-PG is involved in PGE(2) clear...

BACKGROUND While the use of methyldibromo glutaronitrile (MDBGN) in leave-on products is clearly associated with high sensitization or elicitation risk, such a clear-cut relation could be questioned with regard to rinse-off products. OBJECTIVE The objective of this study was to find a maximum non-eliciting concentration for rinse-off products in MDBGN patch test-positive patients. PATIENTS ...
