[Effects of S-adenosylmethionine and S-adenosylhomocysteine on in vivo synthesis of noradrenaline and serotonin in different parts of the rat brain].

S-adenosylmethionine (0,1 mg/kg/ip) decreases in vivo, norepinephrine (NE) synthesis and does not affect 5-hydroxytryptamine (5 HT) synthesis in the Rat brain. S-adenosylhomocysteine (7 mg/kg/ip) increases NE synthesis and decreases 5 HT synthesis. Neither nucleoside affects dopamine synthesis.
