【摘要】 目的:分析中藥注射液干預(yù)對SD大鼠全麻心肌損傷的影響。方法:選擇健康的SD大鼠60只,分為丹紅組、參附組、參照組3組,每組各20只。丹紅組大鼠尾靜脈注射丹紅注射液,參附組注射參附注射液,參照組大鼠注射0.9%的氯化鈉溶液。測定心肌梗死面積、血清以及心肌組織的生化指標(biāo)、分析心肌超微結(jié)構(gòu)病理。結(jié)果:丹紅組和參附組的心肌梗死范圍明顯小于參照組,參附組的MDA、SDN值低于丹紅組和參照組,參附組和丹紅組心臟超微結(jié)構(gòu)辯護(hù)相比參照組病態(tài)明顯減輕(P<0.05)。結(jié)論:參附注射液能夠減輕自由基對心肌細(xì)胞的損傷,起到保護(hù)心肌的作用。

Analysis the Effect of Traditional Chinese Medicine Injection Intervention on the Myocardial Injury of SD Rats/HUANG Jin-rong,ZHU Cheng-cai,LIU Cai-yan.//Medical Innovation of China,2017,14(22):143-146
【Abstract】 Objective:To analyze the effect of traditional Chinese medicine injection intervention on the myocardial injury of SD rats.Method:60 rats of healthy SD were selected,they were divided into three groups:Danhong group,Shenfu group and reference group,20 rats in each group.Danhong group was given Danhong injection,Shenfu group was given Shenfu injection,reference group was injected 0.9% of saline.The area of myocardial infarction,serum and the biochemical index of myocardial tissue,and analysis of myocardial microstructural pathology were measured.Result:The myocardial infarction of the Danhong and Shenfu group were significantly less than the reference group;the MDA and SDN values of the Shenfu group were lower than the Danhong group and the reference group;the reference group was significantly reduced compared with the hyper-microstructure of the Danhong group (P<0.05).Conclusion:The injection can reduce the damage of free radicals to heart muscle cells and protect the heart muscle.

心肌缺血損傷經(jīng)常發(fā)生于急性心肌梗死后的冠脈內(nèi)溶栓術(shù)、冠脈內(nèi)球囊擴(kuò)張血管成形術(shù)以及體外循環(huán)心內(nèi)直視手術(shù)等過程中[1-5]。其機(jī)理復(fù)雜,當(dāng)前醫(yī)學(xué)研究認(rèn)為與細(xì)胞內(nèi)Ca2+超載、氧自由基大量生成、微血管內(nèi)皮組織損傷及血管內(nèi)皮細(xì)胞與血小板之間相互作用有關(guān)[6]。本文通過比較參附、當(dāng)紅注射液對大鼠全麻心肌損傷的影響,對注射液影響結(jié)果進(jìn)行分析,結(jié)果報(bào)道如下。
1 材料與方法
1.1 實(shí)驗(yàn)材料
1.1.1 大鼠 選擇健康的SD大鼠60只,重量220~260 g,雌性30只,雄性30只。
1.1.2 試劑 丹紅注射液,10 mL/支,紅棕色澄明液體,參附注射液,丙二醛(MDA),超氧化物歧化酶(SOD),血清磷酸肌酸激酶(CPK)。
1.1.3 儀器 HX200型動(dòng)物呼吸機(jī);ECG651型心電圖機(jī);BL420E+生物信號記錄分析系統(tǒng);SN-3001酶標(biāo)儀。
1.2 方法 將60只大鼠分為丹紅組、參附組、參照組三組,每組大鼠20只。心肌損傷大鼠模型制作:在大鼠腹腔注射20%烏拉坦 5 mL/kg的麻醉后,將大鼠以仰臥位固定在鼠臺上,使用針狀電極插入右前肢和左后肢皮下,連續(xù)監(jiān)測導(dǎo)聯(lián)心電圖。……
