Figure 6. Effect of halothane on the rate of Calcium²+ -dependent glutamate release evoked by ionomycin. Synaptosomes were preincubated in the absence or presence of 0.6 mM halothane. Glutamate release (mean plus/minus SD (SD shown where larger than symbol)) was monitored spectrofluorometrically after sequential additions of ionomycin and CaCl sup 2.
