摘要
通过标准条件下的表皮试验,我们研究了二硝基氯苯(DNCB)致敏患者对立体异构体氨基酸l- α -丙氨酸和d - α -丙氨酸的二硝基苯基(DNP)偶联物细胞介导的接触敏感性。两种对映体化合物dnp - l - α -丙氨酸(16/26)和dnp - d - α -丙氨酸(17/26)在皮肤阳性反应的数量上没有差异。然而,在早期的研究中,没有患者对位置异构体dnp - β -丙氨酸表现出积极的反应。
[Effect of structure of hapten carrying model substances on contact reaction: DNP conjugates of stereoisomers of alpha-alanine following DNCB sensitization].
By means of epicutaneous tests under standard conditions we studied the cell-mediated contact sensitivity to dinitrophenyl (DNP) conjugates of the stereoisomeric amino acids L-alpha-alanine and D-alpha-alanine, respectively, in patients sensitized with dinitrochlorobenzene (DNCB). There was no difference in the number of positive skin responses with the two enantiomeric compounds DNP-L-alpha-alanine (16/26) and DNP-D-alpha-alanine (17/26). However, as in earlier studies, no patient has shown a positive reaction to the position-isomeric DNP-beta-alanine.
