title: [Effect of sleep deprivation on p38MAPK phosphorylation in the rat hippocampus].
abstract: OBJECTIVE
  To investigate the effect of sleep deprivation (SD) on the expression of p38Mitogen-activated protein kinase (p38MAPK) phosphorylation in the rat hippocampus.
  
  
  METHODS
  Male Sprague-Dawley rats (n=60) were divided randomly into control and sleep deprivation groups. The sleep deprivation models were established with the modified multiple platform methods. At 1 d, 3 d, 5 d, and 7 d after sleep deprivations, changes of neuron morphous in the hippocampal region of the rats were observed by HE staining. The expression of p38MAPK phosphorylation was detected by immunohistochemistry and Western blot. The learning-memory function was tested with Morris water maze and 4-PTT dry path maze.
  
  
  RESULTS
  More obvious neuronal morphous damages, increased p38MAPK phosphorylation cells and p38MAPK phosphorylation expression, and decreased learning-memory function were found in the rats subject to sleep deprivation than those in the control. The changes were enhanced with the length of sleep deprivation.
  
  
  CONCLUSIONS
  p38MAPK can be activated by sleep deprivation, which mediates the process of neuronal injury.
