title: [The effect of Redix Scutellariae on butyrate of Porphyromonas endodontalis in vitro].
abstract: OBJECTIVE
  To study the effect of Radix Scutellariae on the growth, metabolism of Porphyromonas endodontalis (P.e), as a preparation for studying the mechanism of Radix Scutellariae in treating pulp and periapical diseases.
  
  
  METHODS
  P.e was chosen as the experimental bacteria. Radix Scutellariae was extracted by means of reflux with 80% ethanol. The value of MIC of Radix Scutellariae was measured by minute amount serial dilusion test, and the production of butyrate was measured by high liquid chromatograph(HPLC).
  
  
  RESULTS
  Radix Scutellariae could inhibit the growth of P.e, of which the MIC was 100 mg/L. Following the increase in concentration of Radix Scutellariae, the amount of butyrate decreased to (3.527 +/- 0.009) mg/L, (3.048 +/- 0.005) mg/L, (2.490 +/- 0.011) mg/L, (2.209 +/- 0.016) mg/L, respectively (P < 0.05).
  
  
  CONCLUSIONS
  Radix Scutellariae could inhibit the growth and metabolism of P.e and might be an effective agent in treating pulp and periapical diseases.
