Effect of zige lyophilized powder for injection in improving acute cerebral microcirculation disturbance in rats / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the effect of Zige lyophilized powder for injection in improving the acute cerebral microcirculation disturbance in rats.</p><p><b>METHOD</b>Window craniotomy was performed for rats after the drug administration for 14 days. The experimental microcirculation disturbance model was duplicated with high molecule dextran. After the drug administration, the micro-vein diameters of cerebral pla mater of various groups were observed and recorded under the biological microscope. The blood flow volume was monitored by laser Doppler flow-meter. HCT was measured by the electric resistance method. The hemorheological indexes were detected by the auto-hemorheological instrument.</p><p><b>RESULT</b>Zige lyophilized powder for injection (16.40, 32.70, 65.40 mg x kg(-1)) could significantly expand the micro-vein diameter of cerebral pla mater, improve the downward trend of the blood flow volume, and reduce the various hemorheological indexes.</p><p><b>CONCLUSION</b>Zige lyophilized powder for injection shows the effect in improving the cerebral microcirculation.</p>
