近年来,我们诊治了一些哮喘病人。在询问病史时发现,有的人在刷漆后发生哮喘。那末,接触哪类油漆能引起哮喘呢?为什么呢?据了解,聚氨酯漆类可引起哮喘。因为这类漆的成膜物质叫做甲苯二异氰酸酯(TDI),毒性较大,具有明显的刺激和致敏作用。此类化合物,在较高浓度下,对粘膜有刺激作用,可导致支气管炎、支气管肺炎、甚至肺水肿;在极低的浓度下,也能对少数人诱发哮喘或过
In recent years, we have diagnosed some asthma patients. When asked about their medical history, they found that some people developed asthma after painting.

Because such lacquer film-forming material is called toluene diisocyanate (TDI), more toxic, with significant stimulation and sensitization. Such compounds, at higher concentrations, have a stimulatory effect on the mucosa and can cause bronchitis, bronchopneumonia and even pulmonary edema; at very low concentrations, asthma can also be induced in a few people
