Abstract:
Objective To observe the expressions of matrix metalloproteinase-9 mRNA and the change of cerebral edema after diffuse brain injury in rats and discuss their correlation.Methods Marmaruu's diffuse brain injury model of rat was made.Real-time quantitative RT-PCR,dry-wet meth- od,histological techniques and electron microscope were used to determine the expressions of MMP-9 containing water in brain tissue and inflammatory reaction and uhrastructural changes of blood capillary at different time phases after truama.Results The expressions of MMP-9 mRNA started to increase at 1 hour,peaked at 12 hours(P
