Studies on hypersensitivity to "para group".
The author reports the results of patch tests using various aromatic compounds in subjects sensitized to PPD. It was found that aromatic nitro and hydroxyl compounds as well as secondary and tertiary amines do not cause cross-reactions. Positive reactions were obtained only with primary aromatic amines, independently of the position of the amino group in the ring-para, ortho or meta.
