title: [Effects of ginseng and ligusticum drug containing serum on the ERK pathway, proliferation, and vitality of neural stem cells undergoing oxygen-glucose deprivation/reoxygenation culture].
abstract: OBJECTIVE
  To observe the effects of ginseng and Ligustrazine drug containing serum on the proliferation, vitality, and extracellular-signal-responsive kinase (ERK) pathway in neural stem cells undergoing in vitro oxygen-glucose deprivation/reoxygenation culture.
  
  
  METHODS
  The cultured neural stem cells were randomly divided into 5 groups, i.e., the normal control group (Group A), the oxygen-glucose deprivation/reoxygenation group (Group B), the oxygen-glucose deprivation/reoxygenation +ginseng serum group (Group C), the oxygen-glucose deprivation/reoxygenation + Ligustrazine serum group (Group D), and oxygen-glucose deprivation/reoxygenation +ginseng and Ligustrazine drug serum group (Group E).The protein expression levels of ERK and phosphorylated ERK (p-ERK) were observed using immunoblotting. The proliferation of neural stem cells was observed using 5-bromodeoxyuridine (BrdU) incorporation assay. The vitality of neural stem cells was detected using methyl thiazolyl tetrazolium (MTT) colorimetry.
  
  
  RESULTS
  The p-ERK level increased transiently at 10 min and 30 min after reoxygenation, but it decreased to the normal level at 4 h, 6 h, and 1 day, respectively. Compared with Group B, the p-ERK level at 6 h after reoxygenation could be elevated in Group C, D, and E. The proliferation and the vitality of neural stem cells at 1 day after reoxygenation could be enhanced. Furthermore, the effects of combination of ginseng and Ligusticum were better than those of using ginseng or Ligusticum alone.
  
  
  CONCLUSIONS
  Combination of ginseng and Ligusticum could promote the proliferation and vitality of rats' neural stem cells undergoing oxygen-glucose deprivation/reoxygenation culture through ERK signal pathway. Its effects was better than that of using ginseng or Ligusticum alone.
