目的:探讨丹龙醒脑方对大鼠脑缺血再灌注后神经干细胞(NSC)增殖及神经生长因子(NGF)、碱性成纤维细胞生长因子(bFGF)和胶质源性神经营养因子(GDNF)表达的影响。方法60只SD大鼠,随机分为假手术组、模型组、依达拉奉组(3.2 mg/kg )、小剂量组(丹龙醒脑方3.7 g/kg )、中剂量组(丹龙醒脑方7.48 g/kg )、大剂量组(丹龙醒脑方14.8 g/kg ),每组10只。后5组大鼠大脑中动脉栓塞再通法建立脑缺血再灌注模型。各组大鼠治疗7 d后,采用5-溴脱氧尿嘧啶核苷掺入法检测NSC增殖,用免疫组织化学法检测NGF、bFGF、GDNF表达。结果与假手术组比较,模型组NSC增殖数量显著升高、NGF、bFGF、GDNF表达均显著降低(P<0.05);与模型组比较,小、中、大剂量组NSC增殖数显著升高,中、大剂量组NGF、bFGF、GDNF表达均显著降低(P<0.05,P<0.01)。结论丹龙醒脑方可能通过促进NGF、bFGF、GDNF表达促进NSC增殖。
目的:探討丹龍醒腦方對大鼠腦缺血再灌註後神經榦細胞(NSC)增殖及神經生長因子(NGF)、堿性成纖維細胞生長因子(bFGF)和膠質源性神經營養因子(GDNF)錶達的影響。方法60隻SD大鼠,隨機分為假手術組、模型組、依達拉奉組(3.2 mg/kg )、小劑量組(丹龍醒腦方3.7 g/kg )、中劑量組(丹龍醒腦方7.48 g/kg )、大劑量組(丹龍醒腦方14.8 g/kg ),每組10隻。後5組大鼠大腦中動脈栓塞再通法建立腦缺血再灌註模型。各組大鼠治療7 d後,採用5-溴脫氧尿嘧啶覈苷摻入法檢測NSC增殖,用免疫組織化學法檢測NGF、bFGF、GDNF錶達。結果與假手術組比較,模型組NSC增殖數量顯著升高、NGF、bFGF、GDNF錶達均顯著降低(P<0.05);與模型組比較,小、中、大劑量組NSC增殖數顯著升高,中、大劑量組NGF、bFGF、GDNF錶達均顯著降低(P<0.05,P<0.01)。結論丹龍醒腦方可能通過促進NGF、bFGF、GDNF錶達促進NSC增殖。

Objective To study the effect of Danlong Xingnao Recipe (DLXNR) on proliferation of neural stem cells (NSC) and expression of NGF ,bFGF ,GDNF after reperfusion in rats following cerebral ischemia .Methods Sixty SD rats were randomly divided into sham operation group , model group ,3 .2 mg/kg edaravone treatment group ,3 .7 mg/kg DLXNR treatment group ,7 .48 g/kg DLXNR treatment group and 14 .8 g/kg DLXNR treatment group (10 in each group) .A rat cerebral ischemia/reperfusion model was induced by middle cerebral artery occlusion and recanali-zation .Proliferation of NSC was detected by Brdu incorporating after the rats were treated for 7 days .Expressions of NGF ,bFGF and GDNF were detected by immunohistochemistry .Results The expression level of NGF ,bFGF and GDNF was significantly lower in model group than in sham operation group and in 7 .48 g/kg DLXNR treatment group and 14 .8 g/kg DLXNR treat-ment group than in model group (P< 0 .05) .The number of proliferated NSC was significantly greater in 3 DLXNR treatment groups than in model group (P<0 .05) .Conclusion DLXNR can stimulate the proliferation of NSC by up-regulating the expressin of NGF ,bFGF and GDNF .
