Abstract:
AIM: To study the expression of c-fos mRNA in brain following moderate lateral fluid percussion brain injury in rats, and to observe the temporal patterns of its expression following percussion. METHODS: Male Sprague-Dawley rats were divided into normal control, sham operation control and injury group. The rats of injury group subjected to moderate lateral fluid percussion injury (0.2 mPa). The injury groups were then subdivided into 5 min, 15 min, 30 min, 1h, 2h groups according to the time elapsed after injury. The expression of c-fos mRNA was studied with reverse transcription polymerase chain reaction (RT-PCR) semi-quantitatively.RESULTS: At 5 min after percussion, the induction of c-fos mRNA was increased, and remained elevated up to 2 h after brain injury.CONCLUSION: The induction and expression of the c-fos mRNA in cortex and brain stem after fluid percussion brain injury were increased rapidly.
