Research Abstract

Neurotoxic effect of methylmercury or tributyltin was attenuated by de novosynthesized estradiol in rat hippocampal organotypic slice culture. The self-protective function of the neurosteroid might be one of the possible mechanisms for the selective sensitivity of the brain to neurotoxicants. Neurotoxic mechanism of tributyltin, neuroprotective effect of progesterone and allopregnanolone, and distribution of steroids in rat brain were studied.
