Figure 9: Halothane produced a concentration dependent stimulation of alpha1 and alpha2 receptors. Oocytes were perfused with glycine (50 uM) for 30 sec. Oocytes were then perfused with glycine plus halothane (0.16-2.5 mM) for 30 sec. Values are expressed as a percent potentiation above the respective control glycine response (n=4-5).
