영문 초록

Objectives：Purpose of this study was to investigate physiological and neurocognitive effects of total sleep deprivation by using laboratory blood tests and the computerized neurocognitive function test in healthy subjects. Methods：Sixteen healthy volunteers participated in this study. Subjects were recommended to remain awake for 48 hours under continuous surveillance. Lab tests of cortisol, prolactin, thyroid hormone, growth hormone, and immunoglobulin (IgG, IgA, IgM, IgD, IgE), CBC, BC and the Vienna test were performed before and after 48 hours of total sleep deprivation. Results：Concentration of T3 and T4 significantly increased after deprivation. In the reaction test, distribution reaction time significantly increased, and correct reaction significantly decreased. In the vigilance test, amount of correct reaction significantly decreased, and the mean value of correct reaction time was significantly delayed. Level of fasting blood sugar, total protein, albumin, alkaline phosphatase and potassium significantly increased, respectively, except for the level of total bilirubin which was decreased. After total sleep deprivation, WBC counts significantly increased. Regarding immunoglobulin level, IgG, IgA and Ag M concentrations appeared to decrease, but the results were not statistically significant. Conclusion：The effect of total sleep deprivation on physiological function was significant in the level of thyroid hormone. Although statistically not significant, the results of growth hormone and the immune system showed a trend in relations to the effect of total sleep deprivation. Results of blood chemistry suggest that sleep deprivation may influence metabolism of hepatobiliary system. Cognitive impairment was also seen in reactive and vigilant functions after total sleep deprivation.
