对接触甲基四氢化苯二甲酸酐(MTHPA)的144名现作业工人和26名前作业工人的调查研究表明,眼(P<0.001)、咽(P<0.01)、鼻(P<0.01)、哮喘(P<0.05)相关症状发生率显著高于对照组的33人。并且接触者对含有MTHPA的皮肤划痕试验和人类血清蛋白具有较高的阳性(P<0.01)及含有更多的特异
A survey of 144 active workers and 26 former workers exposed to methyltetrahydrophthalic anhydride (MTHPA) showed significant differences in eye (P <0.001), pharynx (P <0.01), nose (P <0.01) Asthma (P <0.05) related symptoms were significantly higher than the control group of 33 people. And the contacts had a higher positive (P <0.01) and a higher specificity for skin scratch tests containing MTHPA and human serum proteins
