SERMs prevent excitotoxic neuronal death in vivo after kainic acid administration. High magnification of the hilus of the dentate gyrus of ovariectomized rats stained with toluidine blue after the i.p. injection of vehicle (Control); kainic acid (KA; 7 mg/kg); tamoxifen (1 mg/kg) and kainic acid; raloxifene (1 mg/kg) and kainic acid; lasofoxifene (1 mg/kg) and kainic acid; bazedoxifene (2 mg/kg) and kainic acid. Kainic acid results in the loss of hilar neurons (large cells). Small cell nuclei correspond to glial cells. Some SERMs, such as tamoxifen, raloxifene, and bazedoxifene, prevent the excitotoxic effect of kainic acid.
