title: [The orthogonal design study on tumor-inhibition and cancer-block role of Chinese medicinal 1023 co].
abstract: OBJECTIVE
  To study the effect of Chinese herb medicine on the inhibition of tumor formation and block of malignant transformation.
  
  
  METHODS
  The Chinese medicine 1023 co. was given by intubation feeding started simultaneously with the painting of 0.5% DMBA on the hamster's cheek mucosa.
  
  
  RESULTS
  The tumor formation in 1023 co. group was delayed for 12 days comparing with the control group and the incidence of dysplasia and cancer in 1023 co. group was lower significantly than that of the control group (P < 0.01).
  
  
  CONCLUSIONS
  The 1023 co. is effective in inhibiting tumor formation and blocking cancerous transformation. By orthogonal design we find the proper prescription is A2 B2 C2 D1.
