O ten lM DBP, a reduction in green fluorescence was observed. Staurosporine (1 lM) was employed as a good handle and caused huge cell death.82 Fig. 1 The effects of growing concentrations of DBP (ten, 50, and 100 nM and 1, 10, 25, 50, and one hundred lM) on ROS formation in cultured neocortical neurons soon after 3, 6, and 24 h of exposure.

The activity was enhanced in DBP-treated neuron cultures by 578 on the activity with the vehicle handle (Fig. 2b). Enhanced enzyme activity was also detected just after 24 and 48 hexposures towards the phthalate. In these prolonged exposures, DBP was helpful even in the decrease concentration of 1 lM. Neurons had been stained with Hoechst 33342 to assess apoptosis. Apoptotic bodies appeared as bright blue fragmented nuclei that showed condensed chromatin, that is characteristic of apoptotic cells.
