Fig. 2.
Effect of ethanol (EtOH, 1 g/kg by gavage) or equal volume of water (H2O) on bolus injections NMDA-evoked (125, 250, 500, or 1000 μg/kg; i.v.) changes in mean arterial pressure (MAP; A) and heart rate (HR; B) in conscious male Sprague-Dawley rats. Representative tracings show the effect of NMDA on mean arterial pressure (MAP; C) and heart rate (BPM; D) in the absence or presence of ethanol. Values are means ± SEM of 4–6 observations.
