Fig. 4.
Docosahexaenoic acid (DHA) played a protective role in TBI rats through Nrf2 signaling pathway. In this figure, a total of 100 rats were evenly divided into four groups: sham, TBI, TBI + DHA and TBI + vehicle (V). a Western blot (WB) and b quantitative real-time polymerase chain reaction (qRT-PCR) assays determined the expression levels of HO-1, NQO-1 and NADPH oxidase (NOX2) in hippocampal tissues of rats in four groups. ***P < 0.001, *P < 0.05, vs. sham; #P < 0.05, ##P < 0.01, ###P < 0.001, vs. TBI + V
