AIM:To investigate the neuroprotective effect of 17β-estradiol(E2)on retina light damage in BALB/c and C57BL/6 mice and provide experimental data for the successful construction of a research model for E2 against retinal light damage.METHODS:Totally 40～45 adult female BALB/c or C57BL/6 mice were divided into six groups, 6 for each group: normal control, ovariectomized control, ovariectomized light(mice were stimulated with continuous white light at 10000 lx for 4, 8, 12, 16, and 24h after 14d of ovariectomy), intravitreal administration sham operation, saline and E2 pre-treatment groups(2μL saline or 10-5mol/L E2 were intravitreal injected respectively after 14d of ovariectomy operation and 24h of dark adaptation). The morphological and functional changes of the retina were detected by paraffin section HE staining, TUNEL staining and electroretinogram.RESULTS:In the ovariectomized light group, the thickness of the inner/outer nuclear layer decreased significantly from the 4h stimulation of 10000 lx white light group. Intravitreal administration of E2 significantly inhibited the apoptosis of retinal cells in the two strains of mice(P |
