近几年来皮肤免疫学的进展为接触性变态反应的反应过程,显示了新的前景.该进展经动物实验研究取得,组成这种重要的进展是:1. 在与一种变应原接触的过程中,通常产生两种竞争性的机制,其一是导致一种特异的变态性皮肤超敏反应而另一是导致特异的免疫耐受性.2. 初次接触变应原,一般在很长时间有时终生在下述二者间起主导作用:效应淋巴细胞的产生(导致皮 The progress of skin immunology in recent years has shown a new prospect for the reaction of contact allergy, which has been achieved through animal experimental studies, and the important advances in composition are: 1. In contact with an allergen Two competing mechanisms usually arise, one of which leads to a specific metamorphic skin hypersensitivity reaction and the other to specific immunotolerance.2 An initial exposure to an allergen, usually very long Time may sometimes play a leading role throughout life: the production of effector lymphocytes (leading to skin
