Fig. 6. Neuroprotective effects of treatment with thiopental and dizocilpine on combined oxygen and glucose deprivation for 5 h in human NT2-N neurons. Concentrations of the drugs are given in micromolars. Cell death was evaluated by measuring lactate dehydrogenase release to the supernatant in percent of oxygen/glucose-deprived controls 24 h after the start of the insult. dzp = dizocilpine; thio = thiopental. *P < 0.01 versus oxygen/glucose-deprived controls. #P < 0.05 versus oxygen/glucose-deprived controls. §P < 0.01 versus 20 μM dizocilpine.
