丹参等药物对大鼠创伤性脑水肿的影响

目的探讨丹参等中西药物对创伤性脑水肿的影响。方法Wistar大鼠130只，随机分为6组：A组为正常对照组，B组为手术对照组，c组为西医治疗组，D、E、F组为中西药合用组，分别给予西药＋丹参注射液、西药＋红花注射液、西药＋三七注射液治疗；经液氮冷冻制备脑水肿模型，检测全血黏度、脑组织含水量、伊文氏蓝（EB）含量、血浆内皮素含量，观察病理学改变。结果D、E、F组全血黏度均较B组显著降低（P〈0．0l或P〈0．05），但c组与B组之间差异无统计学意义（P〉0．05），C、D、E、F同B组相比，脑组织含水量、EB含量和内皮素含量均显著降低（P〈0．01），且D、E、F组明显低于C组（P〈0．0l或P〈0．05）。各中药治疗组脑水肿病理改变显著减轻。结论中药丹参、红花、三七结合常规西医治疗创伤性脑水肿能够取得更好的疗效，其机制可能与其改善微循环、降低内皮素含量有关。

Protective effect of traditional Chinese medicine like Dansen and western medicine on traumatic brain edema

Objective To evaluate the effects of traditional Chinese medicine likeDansen and western medicine in treating traumatic brain edema (TBE). Methods A total of 130 Wistar rats were divided randomly into six groups: Group A (normal contrast group), Group B (operation group), Group C (western medicine treatment group, WM group), Group D (western medicine and salvia injection), Group E (western medicine and Honghua injection) and Group F (western medicine and Sanqi injection). The model of brain edema was established by liquid nitrogen treatment to assay whole blood viscosity, water content and Even blues (EB) in brain tissues and to observe the content and pathologic changes of endothlin (ET) in plasma. Results Whole blood viscosity of Groups D, E and F was lower than that of Group B (P<0.05 or P<0.01), with no significant statistical difference between Group B and Group C (P>0.05). Water content and EB in brain tissues and ET of plasma in Groups C, D, E and F were lower significantly than those in Group B (P<0.01), with significantly lower water content and EB in brain tissues and lower ET of plasma of Groups D, E and F than those of Group C (P<0.01 or P<0.05).The pathologic changes of Groups C, D, E and F were ameliorated significantly compared with Group B. Conclusion Integrated traditional Chinese medicine like Dansen, Honghua, Sanqi and western medicine for TBE can attain better therapeutic effect than solely by western medicine, which may be related to effect of traditional Chinese medicine on improving microcirculation and reducing ET contents.
