Thirty-four patients sensitive to epoxy resin were patch tested with oligomers of epoxy resin. All reacted when tested with MW 340 oligomer. Twenty-three were tested with MW 624 and MW 908 oligomers and seven with MW 1192 oligomer; none reacted. Eight patients tested with commercial mixtures of epoxy resins with an average MW 1280 and MW 1850 reacted to these resin mixtures which contained the MW 340 oligomer. The MW 340 oligomer seems to be the main ingredient responsible for contact allergy to epoxy resins in humans. 相似文献

In the same way that it often is necessary to perform chemical and biological analysis of skin and body fluids in the management of skin disease, it may be necessary to analyze the chemical environment. Some analyses, such as those for nickel, chromate, and formaldehyde, require only simple tests. Others require complex and expensive equipment and specialized skills. In the future, it may become necessary to install some of this equipment for routine use in dermatology clinics. In the meantime, the dermatologist needs to be aware of the possibilities. 相似文献
