Figure 10. In vitro study on Wistar rat lenses cultured for 24 h in Dulbecco’s modified Eagle’s medium: Immunoblots showing differential staining intensity of some apoptotic cascade proteins in the three groups of lenses. Groups of lenses; Group I: Normal lenses incubated in Dulbecco’s modified Eagle’s medium (DMEM) alone (control); Group II: Lenses incubated in DMEM that contained sodium selenite (100 μM selenite/ml of DMEM; selenite-challenged, untreated); Group IIIa: Lenses incubated in DMEM and simultaneously exposed to sodium selenite (100 μM selenite/ml of DMEM) and chrysin (200 μM chrysin/ml of DMEM; selenite-challenged simultaneously chrysin-treated).
