Histamine electrophysiology

Sea urchin toxins extracted from spines or pedicellariae have a variety of pharmacological actions, including electrophysiological ones (75). Dialyzable toxins from Diadema caused a dose-dependent increase in the miniature end-plate potential frequency of frog sartorius muscle without influencing membrane potential (76). A toxin from the sea urchin Toxopneustes pUeolus causes a dose-dependent release of histamine (67). Toxic proteins from the same species also cause smooth muscle contracture in guinea pig ileum and uterus, and are cardiotoxic (77). [Pg.322]

Standard superfusion and electrophysiological techniques do not allow to decide whether an H3 heteroreceptor involved in the inhibition of release of a given transmitter is actually located presynaptically (i.e. on the axon terminals) of the respective neurone. Recent (unpublished) data from our laboratory may serve to illustrate this point. In guinea-pig cerebral cortex slices, noradrenaline release is inhibited by histamine via H3 receptors and facilitated via H2 receptors. Using an appropriate technique (see next paragraph) we found that only the H3 but not the H2 receptor is located presynaptically. [Pg.18]
