- Abstract
- Objectives : This study was performed in order to evaluate the effects of Salviae Miltiorrhizae Radix (SMR) water extract against the cerebral hemorrhage and the blood-brain barrier (BBB) impairment in the intracerebral hemorrhage (ICH).
Method : ICH was induced by the stereotaxic intrastriatal injection of bacterial collagenase type IV in Sprague-Dawley rats. SMR was orally given three times every 20 hours during 3 days after the ICH induction.
Hematoma volume, water content of brain tissue and volume of evans blue leakage were examined.
Myeloperoxidase (MPO) positive neutrophils and tumor necrosis factor-α (TNF-α) were observed with immunofluorescence labeling and confocal microscope.
Results : SMR significantly reduced the hematoma volume of the ICH-induced rat brain. SMR significantly reduced the water content of brain tissue of the ICH-induced rat brain. SMR reduced the percentage of the evans blue leakage around the hematoma on the caudate putamen compared to the ICH group, especially on the cerebral cortex. SMR significantly reduced the volume of the evans blue leakage level in the peri-hematoma regions of the ICH-induced rat brain. SMR significantly reduced MPO positive neutrophils in the peri-hematoma regions of the ICH-induced rat brain. SMR reduced the TNF-α expression in peri-hematoma regions of the ICH-induced rat brain. TNF-α immuno-labeled cells were coincided with MPO immuno-labeled neutrophils in peri-hematoma regions of the ICH-induced rat brain.
Conclusion : These results suggest that SMR plays a protective role against the blood-brain barrier impairment in the ICH through suppression of inflammation in the rat brain tissues.
