The extracellular level of l-[14C]glutamate in synaptosomal suspension in control (1) and in the presence of NDs at a concentration of 0.05 mg/ml (2); 0.1 mg/ml (3); 0.5 mg/ml (4) and 1 mg/ml (5). Data is mean ± SEM of four independent experiments, each of them was performed with different synaptosomal preparations in triplicate. *p < 0.05; **p < 0.001 as compared to control
