Methods Twenty-two adolescent SD female rats were selected. All rats were killed by dislocation of cervical vertebra, the eyeballs were in paraffin imbedding and made to a series of sections, using immunohistochemical method; ERα and ERβ distribution were investigated in uvea tissue of rats; and quantitied by Tanaka scores analytical method. The uteri of rats was used as positive control and PBS as negative control.
