Changes of inflammatory factors, reactive oxygen species and cognitive function in mice after brain-blast injury
Journal Title: Journal of Acute Disease - Year 2018, Vol 7, Issue 6
Abstract
Objective: To study the changes of cognitive function in mouse after brain-blast injury. Methods: Fourty healthy male C57BL/6 mice were randomly divided into model group and control group. After 24 h of injury, histopathological changesc and reactive oxygen species changes were observed under microscope; while changes of inflammatory cytokines content were determined by Western-blot. Four weeks later, Morris water maze method was used to detect the cognition impairment. Results: HE staining showed blast induced brain injury in C57BL/6 mice. Compared with normal control group, the expression of IL-1毬,IL-4, IL-6 were significantly increased in brain tissue of model group whereas IL-10 was significantly decreased (P<0.05); ROS expression in the hippocampus of model group mice was significantly increased compared with that in the control group. Morris water maze showed cognition impairment in mice after brain-blast injury. Conclusions: Brain-blast injury causes cognition impairment in mice, which may be related to the occur of inflammatory change and oxidative stress in the early stage.
