Increased oxidative stress, 7 days after head STZ injection in cockroaches. n = 5. One-way ANOVA with Tukey’s multiple comparisons test indicated a significant increase in (A) ROS (B) TBARS, and (C) DCF levels in neural tissues of cockroaches exposed to 74 and 740 nM STZ head injection, compared with cockroaches in the control group. All values are mean ± SD. * indicates a significant difference from control
