ABSTRACT
AIM To study the effects of baicalin and gardenoside pairing on 5-lox/CysLTs/CysLT pathway of rats with cerebral ischemia injury.METHODS SD rats randomly assigned into control group,model group,baicalin and gardenoside pairing groups (7 ∶ 3,dosed at 30,45,60 mg/kg,respectively) in their cerebral ischemia recovery period were simulated with permanent middle cerebral artery occlusion (pMCAO) if necessary.After a week of natural recovery,the drugs' pharmacodynamic effects were evaluated by the neurofunctional scoring and HE staining,their impact on the content of CysLTs was determined by ELISA,and the influence on the expression of 5-lox,CysLT1 and CysLT2 was detected by western blot.RESULTS One-week consecutive administration of baicalin and gardenoside pairing contributed to a reduction in infiltration and tissue edema of ischemic cells.If compared with pMCAO group,the baicalin and gardenoside pairing groups were observed with significantly lowered scores of neurologic functioning,inhibited microglia activation,decreased content of CysLTs and down-regulated expression of 5-LOX,CysLT1 and CysLT2 (P < 0.01).CONCLUSION Baicalin and gardenia pairing's alleviating effect to the damage of cerebral ischemia may be associated with its inhibition on microglia activation and 5-lox/CysLTs/CysLT signaling pathway,and thus an inflammatory impairment reduction.
