title: [The protective effect of nerve growth factor on PC12 cells to lipopolysaccharide injury].
abstract: OBJECTIVE
  To investigate the effect of nerve growth factor (NGF) on lipopolysaccharide (LPS) injury and activation of nuclear factor-kappa B in PC12 cells.
  
  
  METHODS
  In order to set injury models, the PC12 cells were incubated in different concentration of LPS. Cells were cultured in the culture and were reduced by LPS, and then cells were treated by NGF of various concentrations. The cell viability was determined by methyl thiazolyl tetrazolium (MTT) assay, cellular morphology was observed under inverted microscope and fluorescence microscope, and the content of NF-kappaB was assessed by RT-PCR.
  
  
  RESULTS
  (1) The viability of PC12 cell was decreased with concentration of LPS increasing. (2) The cellular morphology change showed that NGF had an ability to reduce LPS injury. (3) The result of RT-PCR showed that the content of NF-kappaB in LPS injury was more than the normal and treated cell, and the treated one was close to the normal one.
  
  
  CONCLUSIONS
  The reports about NGF in brain cells repair after inflammatory are very small. And our study is about that NGF can protect the PC12 cell from LPS injury, and this mechanism possible bears on the activation of NF-kappaB.
