TIMMS AU - ROBERT G. ENGSTROM Y1 - 1969/09/01 UR - http://molpharm.aspetjournals.org/content/5/5/542.abstract N2 - The presence of 5-hydroxytryptamine has been demonstrated in the parasitic trematode Schistosoma mansoni. The concentration of this biogenic amine is more than 10 times that of mammalian brain. The localization of 5-hydroxytryptamine is not confined to the central nervous system, and consideration should be given to its possible function as a central or peripheral neurotransmitter. ER -
