“Rat brain SAM levels were markedly increased after methionine administration, whereas the convulsant, L‐methionine‐dl‐sulphoximine (MSO), produced a 35 per cent decrease in whole brain content of S‐adenosyl‐L‐methionine (SAM).”
“ SAM levels were reduced by about 50 per cent in the cerebellum, striatum, cortex and hippocampus 3 and 6 h after MSO.”
