title: [Effects of electroacupuncture on behaviors and dopaminergic neurons in the rat of Parkinson's disease].
abstract: OBJECTIVE
  To explore the possibility of electroacupuncture (EA) for prevention of the injury of dopaminergic neurons in the substantia nigra of the rat with Parkinson's disease.
  
  
  METHODS
  Wistar rats were randomly divided into a normal group, a model group, a sham-operation group and an EA group. 6-OH-DA was injected into right substantia nigra of the midbrain to made Parkinson's disease rat model with single side substantia nigra injury, and TH/TUNEL method and rotation behavior observation method were used to observe changes of rotation behavior and apoptosis of dopaminergic neurons in the substantia nigra after EA at "Taichong" (LR 3) and "Fengfu" (GV 16) for 3 d, 7 d and 14 d.
  
  
  RESULTS
  The rotation times/min were same at 3 d, 7 d and 14 d were the basically same in the model group, and at 14 d significantly decreased in the EA group (P<0.05); the rotation starting time at 7 d and 14 d in the model group were significantly longer than those in the EA group (P<0.05); the rotation lasting time at 3 d, 7 d and 14 d in the model group and the EA group were gradually shortened (P<0.01, or P<0.05), but at 7 d, 14 d in the model group were significantly longer than those in the EA group (P<0.05); the DA neuron apoptosis number in the model group were significantly higher than those in the normal group, with a very significant difference (P<0.01); the apoptosis number in the EA group tended to decrease, at 7 d and 14 d were significantly lower than that in the model group (P<0.05).
  
  
  CONCLUSIONS
  Electroacupuncture can effectively prevent from injury of dopaminergic neurons in the substantia nigra of the rat with Parkinson's disease.
