title: [An experimental study(II) on the inhibition of prostatic hyperplasia by extract of seeds of Brassica alba].
abstract: OBJECTIVE
  To study the active components and their functionary mechanism of the extract of Brassica alba seeds, which inhibits experimental mice prostatic hyperplasia.
  
  
  METHODS
  Prostatic hyperplasia of castrated male mice induced by testosterone propionate, the penetrability of capillary vessel of mice skin induced by histamine and the endermic flesh bud of rat induced by filter paper were used as experimental models. Sinalbin and beta-sitosterol separated from seeds of Brassica alba were used to test the activities.
  
  
  RESULTS
  Sinalbin and beta-sitosterol(16.0 mg.kg-1.d-1 and 8.0 mg.kg-1.d-1) could significantly inhibit mice prostatic hyperplasia induced by testosterone propionate and activity of serum acid phosphatase(P < 0.01 or P < 0.05), Sinalbin(16.0 mg.kg-1.d-1)could significantly inhibit the hyperplasia of endermic flesh bud in rat induced by filter paper(P < 0.05), beta-sitosterol(16.0 mg.kg-1.d-1 and 8.0 mg.kg-1.d-1) could significantly decrease the penetrability of capillary vessel of mice skin induced by histamine.
  
  
  CONCLUSIONS
  Sinalbin and beta-sitosterol have anti-androgen and anti-inflammation activities.
