title: Changes of immunoregulatory cells associated with psychological stress and humor.
abstract: For 8 medical students influences of psychological stress or humor on T-cell subset percentages and natural killer cell activity were investigated by measuring these parameters before and after an examination and before and after watching a comedy video. Although T-cell subsets were not significantly affected by either stimulus and natural killer cell activity was not affected by the examination, the latter was significantly decreased after watching the comedy video.
