Effect of Propofol on the Expression of MMP-9 and Its Relevant Inflammatory Factors in Brain of Rat with Intracerebral Hemorrhage.

Intracerebral hemorrhage (ICH) is bleeding in brain caused by the rupture of brain blood vessel, which may lead to patient unconsciousness or death. In this study, we measured the expression of matrix metalloproteinase-9 (MMP-9) and its relevant inflammatory factors in the brain of rat with ICH. The effect of propofol on the expression of MMP-9 and inflammatory factors was investigated. We found the water content in the brain of ICH rats was significantly higher when compared with normal brain. Expression of MMP-9 and inflammatory factors IL-1β and TNF-α were up-regulated in ICH rats. Medium or high concentration of propofol can alleviate ICH in rats by inhibition of the inflammatory factor release and up-regulation of MMP-9 in brain. Our study suggests the inflammatory response after reduction of ICH through promotion of MMP-9 expression and neurite regeneration.
