A simple and rapid functional test system for the screening of histamine H3 ligands is described. It is based on the inhibitory effect of histamine H3 agonists on electrically-evoked contractile response of isolated guinea pig intestine. Whole jejunum segments are continuously stimulated maximally (15 V) by electrical pulses with a frequency of 0.1 Hz and a duration of 0.5 msec. The resulting twitches are recorded isotonically (1.0 g) and can be completely abolished by atropine (0.1 mcM).
