title: Influence of citalopram and chlorimipramine on uptake of 5-HT by isolated perfused guinea pig lungs.
abstract: A method is described for the preparation and perfusion in vitro of isolated guinea pig lungs, 5-HT is rapidly taken up from a perfusing solution by the organ (about 70% uptake). In the concentration range 10(-7) to 5 X 10(-6) M citalopram concentration dependently inhibited the uptake of 5-HT by the lung preparation. Chlorimipramine inhibited the uptake of 5-HT only by 40--50%, and the inhibition was not concentration dependent. The method used seems to be a reliable model for studying the uptake of 5-HT.
