ROS levels in CD3
+ lymph node T cells 48 h post SEB injection. Balb/c mice (n = 3 per group) were treated as described in the Materials and Methods. (A) The percentage of CD3+/ROS+ lymph node T cells from each treatment group are shown. (B) The effect of PPC on the level of ROS per CD3+ lymph node T cell in the SEB (red line) and SEB + PPC groups (blue line) are shown. Error bars represent standard deviation.
