title: [Clinical observation on the efficacy enhancing and toxicity attenuating effect of nuzhen yangyin granule to the anti-parkinsonism therapy mainly with Medopa].
abstract: OBJECTIVE
  To observe and assess the efficacy enhancing and toxicity attenuating effect of Nuzhen Yangyin Granule (NYG) to the anti-parkinsonism (paralysis agitans) therapy with Medopa and Artane.
  
  
  METHODS
  Adopting the randomized double-blinded method, the effect of adding NYG to 30 patients with Parkinsonism in the treated group, who already received anti-Parkinsonism treatment but showing decreased response to Medopa and Artane and with obvious adverse reaction, was observed and controlled by 30 patients treated by adding placebo.
  
  
  RESULTS
  The total effective rate in the treated group and the control group was 86.7% and 56.7% respectively, the total syndrome improving rate was 90% and 56.7% respectively and the toxicity attenuating rate 90% and 43.3% respectively, comparison between the two groups showed significant difference (P < 0.05 or P < 0.01). NYG also showed markedly effective in reducing the adverse reactions of Medopa and Artane on digestive, neuro-psychiatric and cardiovascular system.
  
  
  CONCLUSIONS
  NYG has obvious efficacy enhancing and toxicity attenuating effects caused by the anti-Parkinsonism treatment with Medopa and Artane.
