Aminophylline and Ephedrine, but Not Flumazenil, Inhibit the Activity of the Excitatory Amino Acid Transporter 3 Expressed in Xenopus Oocytes and Reverse the Increased Activity by Propofol

Figure 3

Concentration-response curves of excitatory amino acid transporter type 3 (EAAT3) to L-glutamate in the presence or absence of 95.1 μM aminophylline (a) and 1.19 μM ephedrine (b). Data are means ± SEM, n = 8–28 for each data point. < 0.05 compared with the corresponding controls.
