Is increased extracellular serotonin level in rat hippocampus induced by chronic citalopram augmented by subchronic lithium : neurochemical and behavioural studies in the rat?
The present results support the assumption that increases in hippocampal 5-HT neurotransmission may be important in the augmentatory effect of lithium.
(1) L-glucose seems to have a weak affinity for a D-glucose carrier and is not a marker of paracellular transport, and (2) paracellular transport accounts for a minimal fraction of D-glucose uptake; this fraction is not enhanced by ingestion of D-glucose or chow.
