    oral OXT significantly increased plasma OXT concentration changes
    2 context sentences
    Summary · context
    Seventy healthy females participated in the current randomized, placebo-controlled, pharmaco-imaging clinical trial, and the results were compared with our previous data from 75 males who underwent the same protocol.
    Summary · context
    Participants were randomly assigned to OXT (24 IU) or placebo (PLC) groups and completed an implicit emotional face paradigm (angry/fear/happy/neutral) where they were only required to identify face gender.
