Abstract: This article attempts to investigate the effects of acute psychological stress on immune function in college stu?鄄dents with different personality types. 56 college students participated the test of Eysenck Personality Questionnaire(EPQ). Stress group performed public speech. The concentration of serum Interleukin-6(IL-6)and Tumor Necrosis Factor-α(TNF-α)were analyzed by using radioimmunity. The results of the experiment were as follows: Compared with control group, the concentration of serum TNF-α of introversion group and motion stability group obviously in?鄄creased after acute psychological stress and there were no significant differences in others groups. This suggested that up-regulation of natural immunity of undergraduates with introversion and motion stability was significant but not significant for undergraduates with extraversion and motion unstability after acute psychological stress.

摘要： 以56名大学生为研究对象，用艾森克人格问卷（EPQ）进行测试，用公共演讲作为应激源，用放射免疫法测定血清肿瘤坏死因子α（TNF-α）和白细胞介素6（IL-6）的含量，旨在探讨急性心理应激对不同人格类型大学生免疫功能的影响。实验结果发现：与对照组相比，急性心理应激后内向组和情绪稳定组TNF-α的明显升高，其余变化均不显著。这说明急性心理应激引起内向、情绪稳定的个体自然免疫增强的现象较明显，而对外向、情绪不稳定个体的作用不明显。
