This study investigated the effects of estradiol valerate (EV) and tibolone (TB) treatments on some memory parameters of ovariectomized young (2 months), adult (8 months) and old (20 months) female rats. A Sham-operated group was used as control and the animals were treated daily, by oral gavage, with saline (Sham and placebo NR group), EV (0.3 mg/kg) or TB(More)

Bisphenol A (BPA), used to manufacture polycarbonate plastics, is an ED recognized for its estrogenic, anti-estrogenic, and anti-androgenic effects. Behavior is considered a vital characteristic for an animal's life cycle. This study evaluated the effect of exposure to low(More)
Estrogen compounds have been described as important brain protectors. This study investigated the effects of estradiol valerate (EV--0.3 mg/kg) and two concentrations of tibolone (TB1=0.5 mg/kg and TB2=1 mg/kg) on brain oxidative stress parameters and blood biochemistry in ovariectomized female rats, of three different age groups (young--2 months, adult--8(More)
