葛根芩连汤不同配伍对黄芩苷、小檗碱含量的影响

目的研究葛根芩连汤在不同配伍的情况下黄芩苷、小檗碱含量的变化。方法采用反相高效液相法,选用PhenomenexC18柱(4.6mm×250mm),流动相为甲醇磷酸盐缓冲液(pH3),检测波长分别为280nm(黄芩苷)、346nm(小檗碱)。结果不同配伍对葛根芩连汤中黄芩苷、小檗碱含量影响显著。结论黄芩苷与小檗碱在煎煮后形成沉淀,从而使葛根芩连汤中的黄芩苷和小檗碱的含量大大降低。     

桃仁-红花"药对"不同配比的血府逐瘀汤对急性心肌缺血的保护作用

目的观察桃仁-红花“药对”不同配比的血府逐瘀汤抗垂体后叶素(Pit)致大鼠急性心肌缺血的作用。方法采用大鼠舌下静脉注射Pit造成急性心肌缺血模型,观察各给药组注射Pit后不同时间点Ⅱ导联心电图ST段变化以及血清乳酸脱氢酶(LDH)、肌酸激酶(CK)、超氧化物歧化酶(SOD)、丙二醛(MDA)的含量。结果桃仁、红花不同配比的血府逐瘀汤对Pit所致缺血性ST段有明显改善作用,能明显增加血清SOD的活性,降低MDA、CK和LDH的含量,其中桃仁、红花配比为4∶3时效果最为显著。结论桃仁、红花不同配比的血府逐瘀汤均具有明显对抗Pit致大鼠急性心肌缺血的作用,其功效与桃仁-红花的不同配比之间关系不明显。     

葛根芩连汤配伍规律的研究

目的研究葛根芩连汤不同配伍对主要化学成分、药理效应变化的影响,综合分析该方的配伍规律。方法采用HPLC法测定各主要成分,考察HPCE指纹图谱的变化,药理指标采用体外抑菌、体内抑菌、解热试验、抗腹泻试验和病理损害模型。结果葛根和黄连降低黄芩苷的含量,黄连降低甘草酸的含量,葛根、黄芩、甘草使小檗碱的含量降低。配伍产生的沉淀,经分析含有黄芩苷、小檗碱、葛根素、甘草酸。各药配伍组合中,以黄连的体内外抑菌活性最强,不同的菌株强度有差异;解热试验中,最佳组合为葛根和黄芩;在抗腹泻试验中,最佳组合为黄连和炙甘草。结论从治疗“协热下利”证来说,全方4味药组合最佳。     

八味地黄汤各药味对附子生物碱影响的电喷雾质谱研究

目的以八味地黄汤为研究对象,考察各药味对附子生物碱的影响规律,揭示附子配伍组方的科学内涵,为科学阐释八味地黄汤配伍规律提供化学依据。方法利用电喷雾质谱技术分别对八味地黄汤,附子加山茱萸、山药、肉桂、丹皮、泽泻、地黄、茯苓共煎液以及次乌头碱加山茱萸、山药共煎液进行系统考察。结果次乌头碱加山药、山茱萸,附子加山药等共煎液中次乌头碱含量较高;八味地黄汤、附子加山茱萸共煎液中次乌头碱含量较低;肉桂、丹皮、泽泻、地黄、茯苓等对附子生物碱的影响不明显。结论八味地黄汤中乌头碱和中乌头碱水解和溶出比较完全,次乌头碱的含量较少,次乌头碱的减少是由于水解以及溶出受到抑制导致。其中山茱萸对制附子起减毒作用,其减毒机制主要是抑制了制附子中次乌头碱的溶出。而山药则能导致附子毒性增加。     

以血清药理学方法研究黄连解毒汤对小鼠的药效动力学

目的以含药血清对小鼠肝匀浆体外生成丙二醛(M DA)的抑制作用为指标,研究黄连解毒汤及单味药水煎剂的药效动力学。方法测定小鼠ig黄连解毒汤及单味药所得含药血清对M DA生成作用的经时过程,并考察黄连解毒汤含药血清、单味药煎剂及小檗碱、黄芩苷抑制M DA生成作用的剂量-效应关系。结果小鼠ig黄连解毒汤、黄连、黄芩、黄连 黄芩后,含药血清均可抑制体外肝匀浆M DA生成,且作用呈剂量依赖性。各药的Em ax分别为86%、76%、79%及81%;tm ax分别为180、120、5及15 m in;其煎剂对M DA生成抑制作用呈剂量依赖性;小檗碱在0.12~10 ng/mL无明显的抑制作用;黄芩苷在1.11~10μg/mL有抑制作用,且作用亦呈剂量依赖性。结论黄连解毒汤体内抗氧化作用强于各单方。黄芩苷可能是黄芩药液和含药血清中的抗氧化成分之一,而小檗碱可能与含药血清抗氧化作用无关;小鼠ig黄连解毒汤及其单味药所得含药血清对M DA生成呈时间和剂量依赖性。

Intervention Effects of Jianpi Liqi Huoxue Decoction (健脾理气活血汤) on Lipid Peroxidative Liver Injury by Alcohol

Objective: To study the intervention effects of Jianpi Liqi Huoxue Decoction ( 健脾理气活血汤, JLHD) on lipid peroxidative liver injury induced by alcohol. Methods: The rat alcoholic model of liver disease (ALD) induced by Lieber-DeCarli liquid diet was established. Thirty-two male SD rats were randomly divided into 4 groups: the normal group ( n = 5), the control group ( n = 9), the model group ( n = 9) and the JLHD group (n = 9). From the 4th week after modeling, the rats were given JLHD or distilled water by gastrogavage respectively, and the samples of blood and liver tissues were taken out from the rats for determination by the end of the 8th week. The hepatic pathological changes were observed with HE staining; the liver injury related indices, including activity of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in serum, γ-glutamyl transpeptidase (γ-GT) activity and triglyceride (TG) content in liver tissues, as well as the lipid peroxidation related indices, including malonaldehyde (MDA) content and nitric oxide synthase (NOS) activity in liver tissue, serum Fe2 level, and the anti-peroxidation capacity related indices, including superoxide dismutase (SOD) activity, glutathion ( GSH) content and reactive oxygen species (antiROS) activity in liver tissues were determined. Results: ( 1 ) There were obvious figures of fatty degeneration and inflammatory infiltration in liver tissues of the model group. As compared with the control group, in the model group, the activity of ALT and AST, and Fe2 content in serum, γ-GT and NOS activity, TG and MDA content in liver tissues were significantly higher ( P＜0.01 ), while the activity of SOD, GSH and anti-ROS in liver tissues were significantly lower ( P＜0.01 ). (2) The fatty degeneration and inflammatory infiltration of liver tissues in the JLHD group were significantly lessen as compared with those in the model group; and the abnormalities of all the indexes revealed in the model rats were restored to certain extent in the JLHD group,and especially significant were the levels of ALT activity, MDA content and Fe2 , which were nearly normal.Conclusion: JLHD has significant effects against alcoholic liver injury, the acting mechanism of which is likely to be related with its anti-lipid peroxidative effect.
