摘 要:目的 观察何氏加味定喘汤对慢性支气管炎大鼠氧化/抗氧化相关指标的影响.方法 SD大鼠50只,采用改良烟熏法复制慢性支气管炎模型,从造模第20天起,空白对照组及模型对照组用0.9%氯化钠注射液1 ml/100 g,给药组按1 ml/100 g体积灌胃,阳性对照组用止嗽合剂(5g·kg-1·d-1)灌胃,何氏加味定喘汤高剂量组(20g·kg-1· d-1)、何氏加味定喘汤中剂量组(10 g·kg-1·d-1)、何氏加味定喘汤低剂量组(5 g·kg-1·d-1)分别灌胃,各组灌胃均为每天1次.各组均用药20 d.观察治疗后大鼠血清、肺组织匀浆、肺泡灌流液中超氧化物歧化酶(SOD)、过氧化氢酶(CAT)及丙二醛(MDA)含量.结果 慢性支气管炎模型组大鼠血清、肺组织匀浆及肺泡灌洗液中SOD[(188.11±9.37) U/ml、(276.11±30.28) U/ml、(8.80±1.49)U/rml]、CAT(9.40±2.04) U/ml、(26.57 ±4.26) U/ml、(1.58±0.26)U/ml)]等清除自由基的酶类活性,较空白对照组SOD、CAT显著降低(P<0.01);血清、肺组织匀浆及肺泡灌洗液中的脂质过氧化物MDA[(5.64 ±0.52) μmol/L、(6.32±2.10)μmol/L、(28.08±2.43)μmol/L]]的含量较空白对照组增加(P<0.05或P<0.01),何氏加味定喘汤可有效地逆转这些改变(P<0.05或P<0.01),并呈明显的剂量依赖性,何氏加味定喘汤中、高剂量组大鼠血清中SOD[(253.05±7.81) U/ml、(256.92±5.37) U/ml]、CAT(14.86±2.49) U/ml、(18.22±2.65) U/ml)]活性比空白对照组还略高,何氏加味定喘汤中、高剂量组大鼠及肺组织匀浆中SOD[(470.91±11.46) U/mgprot、(482.91±14.32) U/mgprot]、CAT(46.87±3.75) U/mgprot、(55.49±3.33) U/mgprot)]活性亦比空白对照组还高.何氏加味定喘汤高剂量组大鼠血清及肺组织匀浆中MDA含量[(3.57±1.04)μmol/L]接近正常组水平.何氏加味定喘汤高剂量组大鼠肺泡灌流液中SOD(16.15±0.86) U/ml、CAT(2.88±0.25) U/ml活Objective To study chronic bronchitis rats oxidant/antioxidant related indicators Ho flavored Dingchuan Decoction.Methods 50 SD rats were adopted improved smoked method to make chronic bronchitis model.From the 20th day of the modeling,blank control group and model control group gavage were treated with saline.The positive control group were treated with Cough Mixture.The experimental groupwere dealed with Ho flavored Dingchuan Decoction high,medium and low-dose.20 day later,the cotent of SOD,CAT,MDA in rat serum,lung tissue and balf were observed.Results Compare to blank control group,the cotent of SOD[(188.11 ± 9.37)U/ml、(276.11 ±30.28) U/ml,(8.80 ± 1.49)U/ml],CAT[(9.40 ±2.04)U/ml,(26.57±4.26)U/ml,(1.58±0.26) U/ml] in rat serum,lung tissue of the experimental group significantly reduced (P 〈0.01) ; MDA [(5.64 ± 0.52) μmol/L,(6.32 ± 2.10) μmol/L,(28.08 ± 2.43) μ mol/L) increased (P 〈0.05 or P 〈 0.01).Ho flavored Dingchuan Decoction can effectively reverse these changes,and showed a significant dose-dependent.The Ho flavored Dingchuantang,in middle and high-dose serum SOD [(253.05 ± 7.81) U/ml,(256.92 ± 5.37)U/ml],CAT [(14.86 ± 2.49)U/ml,(18.22 ± 2.65)U/ml] higher than those of blank control group.And the Ho flavored Dingchuantang,in middle and high-dose lung tissue SOD [(470.91 ± 11.46)U/mgprot,(482.91 ± 14.32)U/mgprot),CAT [(46.87 ± 3.75)U/mgprot,(55.49 ±3.33)U/mgprot] higher than those of blank control group.Content close to the normal level.Conclusion The Ho flavored Dingchuan Decoction has significantly reduce the oxidative stress in chronic bronchitis.
