Specimens obtained from human skin following the induction of erythema responses with long ultraviolet (UVA) and with middle ultraviolet (UVB) radiation alone were compared histologically to determine whether the effects of these two portions of the electromagnetic spectrum were the same. It was found that, except for similar dermal inflammatory changes, the effects of UVA were not the same as those of UVB; characteristic epidermal sunburn damage was induced by the latter, but not by the former.
分别用长波紫外线（UVA）和中波紫外线（UVB）单独诱发人体皮肤红斑反应后获取的标本，进行了组织学比较，以确定这两个电磁波谱部分的效应是否相同。结果发现，除了类似的真皮炎症变化外，UVA的效应与UVB的不同；后者可诱发典型的表皮晒伤损伤，而前者则不会。
