醫(yī)學論文范文:加減防己黃芪湯對糖尿病皮膚潰瘍大鼠血清NO、ET1水平的影響
【摘要】 [目的]觀察加減防己黃芪湯對糖尿病皮膚潰瘍大鼠血管內(nèi)皮功能的影響。[方法]選用SD雄性大鼠90只,隨機選取6只為正常對照組,其余大鼠以尾靜脈注射四氧嘧啶40mg/kg,選取符合糖尿病診斷標準的大鼠用于建立糖尿病皮膚潰瘍模型造模,并隨機分成6組,模型對照組、加減防己黃芪湯干預的高、中、低劑量組,中藥對照組、西藥對照組。實驗結束后斷頭取血檢測NO、ET1含量以加減防己黃芪湯對觀察對血管內(nèi)皮功能的影響。[結果]與模型組比較,各治療組大鼠血清NO含量均有不同程度升高,而血漿ET1含量卻有不同程度的降低,其中以加減防己黃芪湯高劑量組變化最明顯(P<0.001),中劑量明顯(P<0.01),低劑量、中藥對照組次之(P<0.05)。加減防己黃芪湯各劑量組的調(diào)節(jié)作用與劑量呈現(xiàn)相關性。[結論]加減防己黃芪湯可通過升高血清NO含量、降低血漿ET1水平來改善血管內(nèi)皮功能。

Abstract: [Objective]To explore the cure effect of Astragalus Tetrandrae Decoction on vessel endodermis function of rats with diabetic derma ulcer.[Method]Select 90 SD male rats,take 6 as normal control group,others were injected by tail vein with Alloxan;choose rats in accordance with diabetic diagnosis to set up model of diabetic derma ulcer,and randomly divide them into 6 groups: model control(1),high,middle and lowdosage groups(2,3,4)of Astragalus Tetrandrae Decoction,TCM control(5)and WM control(6);after test,make decapitated and take blood for NO and ET1 to observe effect of the decoction on vessel endodermis.[Result]Compared to model group,all NO in treated groups was raised in different extent,While plasma ET1 content reduced in different degree;among which,group 2 was the most obvious,then groups 3 and 5;the regulation was related with dosage.[Conclusion]The decoction can improve vessel endodermis function by raising NO and reducing ET1 level醫(yī)學全.在線gydjdsj.org.cn.

糖尿病皮膚潰瘍發(fā)病基礎是脾虛失運,濁瘀經(jīng)絡,積久成毒,化腐傷肌。故提出運脾通絡法是防治糖尿病足(皮膚潰瘍)的有效方法[1]。據(jù)此我們以防己黃芪湯為基本方,結合臨床化裁出八味中藥,制成加減防己黃芪湯。觀察該方對糖尿病皮膚潰瘍大鼠血清NO、ET1水平的影響,以探討其作用機制。
