ABSTRACT
Objective: To observe the effects of new Qingkailing injection on the toxic substances accumulation post-hematencephalon.Methods: Using VII-type collagenase inducing rat hematencephalon,the contents of TNF-?,IL-1? and sICAM-1 of brain homogenate were detected by ELISA;the contents of SOD and MDA were determined separately by xanthine oxidase method and thio-barbituric acid method; brain water content was detected by dry-wet weight method;serum NSE content was determined by liquid phase competition method.Results: Inflammatory reaction was fierce 48 h after hematencephalon in rat,and that new Qingkailing injection could effectually lower the contents of the inflammatory factors,MDA,brain water content and NSE,and could heighten the content of SOD.Conclusion: New Qingkailing injection has favorable heat-clearing and detoxicating effects on the pathologic state of flourishing toxic heat post-hematencephalon.
ABSTRACT
Objective: To observe the expression of cell adhesion molecules ICAM-1 and VCAM-1of cultured rat brain microvascular endothelial cells(MVEC),expecting to explore the mechanisms of new QingKaiLing injection protecting brain from injury of inflammatory cascade in cerebral ischemia diseases.Methods: Rat cerebral MVEC were extracted by separating microvessel sections and collagenase enzymatic digesting,an in vitro ischemia reperfusion model was established(Kreb,95%N2+5%CO2),the protein and mRNA expression of ICAM-1 and VCAM-1 were detected by using immunocytochemical stain and RT-PCR method.Results:The expression of adhesion molecules of model group were significantly higher than those of noral group(P
