Serine racemase protein expression in cortex and hippocampus in schizophrenia.

abstract：:The synthesis and release of 3H-acetylcholine was measured in hippocampal slices of adult rat brain following acute in vitro exposure to ethanolamine. Evoked release of 3H-acetylcholine was elevated by 60-70% but 3H-acetylcholine synthesis was unaffected. Other amino alcohols were also found to significantly increase ...
