The frequency and immunological background of dermatitis occurring in lichen pickers during the 3- to 4-month picking season were studied in a small community in northern Finland. Thirty of 164 lichen pickers had suffered from dermatitis at least on the fingers and the dorsa of their hands, and many of them also had dermatitis on their forearms, faces, etc. Fifteen of them were subjected to epicutaneous and photo-epicutaneous testing with crushed Cladonia alpestris (L.) Rab. and some fractions of it. Allergic contact reactions were seen in nine subjects, three of whom also had positive photo-epicutaneous test reactions from lichen allergens. No immediate reactions were seen in scratch or scratch chamber tests with crushed Cl. alpestris or with its alcoholic extract.
在芬兰北部的一个小社区，对苔藓采集者在3至4个月的采集季节中发生皮炎的频率和免疫背景进行了研究。164名苔藓采集者中有30人至少手指和手背患过皮炎，其中许多人前臂、面部等部位也有皮炎。其中15人接受了用碾碎的高山石蕊（Cladonia alpestris (L.) Rab.）及其部分提取物进行的表皮和光表皮试验。9名受试者出现了过敏性接触反应，其中3人对苔藓过敏原的光表皮试验反应也呈阳性。在用碾碎的高山石蕊或其酒精提取物进行的划痕或划痕室试验中未观察到即刻反应。
