Relations between feelings and salivary IgA secretion were assessed in co-medical students attending a lecture.The assessments were performed twice in two different classes held in December, 1999 and October, 2000 in the same manner, then the data of the two trials were combined and analyzed. On the basis of the impression of the lecture, students were divided into two groups: a group who felt interested and another group who felt indifferent or bored. Saliva samples were taken three times, at the beginning of, at the end of, and 15 minutes after the class, then the secretory IgA in saliva was determined by ELISA.At the end of the class, an increase in salivary IgA secretion was seen in the group who felt interested, while not in the group who felt indifferent or bored. The increasing change in salivary IgA secretion was, however, moderate and transient, namely it increased only by about +30% on average, and returned to the initial level after 15 minutes.
在参加讲座的医学生中评估了情感与唾液分泌型 IgA 之间的关系。1999 年 12 月和 2000 年 10 月，以相同的方式在两个不同的班级中进行了两次评估，然后将两次试验的数据合并进行分析。根据讲座的印象，学生被分为两组：一组感觉有趣，另一组感觉无趣或无聊。采集唾液样本三次，在开始时、结束时和课程结束后 15 分钟，然后通过 ELISA 法测定唾液中的分泌型 IgA。在课程结束时，感觉有趣的组唾液分泌型 IgA 分泌增加，而感觉无趣或无聊的组则没有。然而，唾液分泌型 IgA 分泌的增加变化是适度和短暂的，即平均仅增加约 30%，并在 15 分钟后恢复到初始水平。
