title: [The effects of E2 and it's metabolites on the proliferation of rat anterior pituitary cells in vitro].
abstract: OBJECTIVE
  The present work is determined to observe the effects of E2 (estradiol), 2-OHE1 (2-hydroxyestrone), 2-OHE2 (2-hydroxyestrodiol) on the proliferation of rat anterior pituitary cells (APC) in vitro by laser scanning confocal microscopy.
  
  
  RESULTS
  10(-6) mol/L E2 stimulated the growth of APC. After 2 days of incubation with E2, the DNA content of APC increased to 1.3 times of the control group (P < 0.01). 10(-6) mol/L 2-OHE2 (other than 2-OHE1) stimulated proliferative activity of APC and inhibited the inhibitory effect of peribidil (10(-5) mol/L), a dopamine receptor agonist, on the poliferative activity of rat APC.
