PG - 274-7 LID - S1995-7645(16)00028-6 [pii] LID - 10.1016/j.apjtm.2016.01.027 [doi] AB - OBJECTIVE: To observe the effect of nuclear transcription factor-kappaB (NF-kappaB) on cerebral edema in rats with traumatic brain injury (TBI). METHODS: Male SD rats with fluid percussion injury (FPI) were selected. After separation and culture, rats' astrocytes all suffered FPI. The expression of NF-kappaB and the water content were detected at the animal and cellular levels, while the activity of NOX was evaluated at the cellular level. RESULTS: According to the results, the positive expression of NF-kappaB and expression of mRNA were significantly increased and the water content was increased for rats after TBI, while NF-kappaB inhibitor BAY11-7082 could significantly reduce the effect of TBI. 1 and 3 h after FPI of astrocytes, the activation of NF-kappaB was increased and BAY 11-7082 could significantly improve the injury-induced swelling of astrocytes. After the injury of astrocytes, the activity of NOX was also increased, while BAY 11-7082 could reduce the activity of NOX. CONCLUSIONS: The results show that the activation of NF-kappaB in astrocytes is a key factor in the process of cerebral edema after TBI of rats. CI - Copyright (c) 2016 Hainan Medical College.
