Male Wistar rats were injected intraperitoneally with either saline, L-trytophan, D,L-5hydroxytryptophan, L-tyrosine, L-DOPA or choline and killed by the near-freezing method 15 and 45 min after injection. The brains were removed, pulverized and acetylcholine, dopamine, norepinephrine, 5-hydroxytryptamine, aspartate, glutamate, glycine and γ-aminobuttyric acid wwere extracted and concurrently measured using previously reported methods. Compared to saline injected controls, some precursors not only resulted in changes in the specific neurotransmiter systems being pertubated, but also changes in the content of other neurotransmitters.
