Differential down-regulation of estrogen receptor-like immunoreactivity by estradiol in the female Brazilian opossum brain.

abstract：:Cytotoxic effects of L-glutamate and related compounds were investigated on rat glioma C6 cells in vitro. Within 12-24 h, addition of glutamate to the culture medium, resulted in degeneration of the C6 cells. The ED50 for glutamate-induced damage was about 4 mM. Seventeen structural analogues of glutamate, including a...
