ABSTRACT
OBJECTIVE: To study the protective effects of sparstolonin B(8,5'-dihydroxy-4-phenyl-5,2'-oxidoisocoumarin, SsnB) on mouse with intracerebral haemorrhage (ICH). METHODS: The effect of SsnB on neuronal cell death induced by Hb using a microglia-neuron transwell system was investigated. Autologous nonanticoagulated blood was collected from the tail artery of the mouse and then injected into the striatum using a syringe pump. Neurological deficit of the mouse with ICH was assessed 1,3,5 and 7 d after SsnB administration using modified neurological severity score system, and brain water content of the mouse cerebral tissues after ICH was measured at the same day. The concentrations of pro-inflammatory cytokines in perihematoma tissues, including interleukin-6, interleukin-1 p and tumor necrosis factor-α, were measured by ELISA assay. RESULTS: The results show that SsnB significantly reduced the neurological deficit scores and the brain water content, and inhibited the levels of IL-6, IL-1β and TNF-α at first day and third day after ICH. CONCLUSION: SsnB can improve the brain injury in mouse induced by ICH. The mechanism may involve increased the neuronal survival rate and decreased expression of pro-inflammatory cytokines of mouse after ICH.
