The numbers of animals used for each condition

Group Conditions Pathological examination Rt-PCR array
G-1 10-min post exposure 5 6
G-2 4-h post-exposure 5 4
G-3 7-day post-exposure 5 5
G-4 Control 6 7

Note: (1) For the mRNA analysis, three animals (one from the 10-min group, one from 7-d group and one from the control group) were excluded from the final analysis due to sample contamination. (2) Three additional rats were used for the mRNA analysis of apoptosis-related genes with the hippocampal tissues.
