Descrição geral

p-Tolyl isocyanate reacts with human serum albumin to form antigen which helps in detecting IgE antibodies in workers hypersensitive to toluene diisocyanate.

Aplicação

p-Tolyl isocyanate was used to study the catalytic role of supported Rhodium(I) complex toward the reductive carbonylation of nitrobenzene in DMF medium.

Radioallergosorbent testing was used to look for the presence of specific IgE antibody against a para-tolyl-mono-isocyanate human serum albumin conjugate in sera from five groups of subjects. The first three groups consisted of individuals exposed to toluene diisocyanate (TDI) who

Toluene diisocyanate (TDI) sensitivity accompanied by nonspecific bronchial hyperresponsiveness occurs in approximately 5% of occupationally exposed workers. We report the case of a 32-yr-old worker followed longitudinally after removal from isocyanate exposure. TDI reactivity was lost 11 mo after removal

Sera of 91 people were assayed for IgE which bound to a p-tolyl-isocyanate-human serum albumin conjugate. The sera came from 20 blood donors, 70 factory workers, and 1 casualty patient. Three factory workers had abnormally high assay values in association

Sera from 149 occupationally exposed toluene diisocyanate (TDI) workers were tested by RAST with p-tolyl monoisocyanate human serum albumin (TMI-HSA). Of the seven positives, one had a history suggestive of TDI asthma and one had a rash which may have

A worker developed two episodes of severe asthma 90 min after cutting a polyurethane plate made of diphenylmethane diisocyanate (MDI) using a rapidly turning carbide blade. Intradermal skin testing with MDI-human serum albumin (MDI-HSA) and p-tolyl isocyanate-HSA (p-TMI-HSA) were positive
