2008, (6): 422-426.
Abstract:
Objective: To investigate the protective effect of Yixin oral liquid(YOL)preconditoning on acute myocardial ischemia in rats. Methods: The model of acute myocardial ischemia was established on rats by left coronary artery ligation,then the rats were divided into 7 groups randomly:sham operation group,Model group,Diltiazem hydrochloride group,Fufang Danshen Dripping Pills group(FD) and various concentration of YOL groups(high,medium and low doses).The change of J point of ECG,the left ventricular function (LVSP,LVEDP,±dp/dtmax),the superoxide dismutase(SOD)and malonaldehyde(MDA)contents in serum,and the pathologic structure of ischemic rats were observed. Results: The YOL preconditoning could obviously antagonize J point raise and deterioration of left ventricular function compared with the model group(P<0.05),in which the high and medium dose groups with YOL are better;and there were no significant difference between FD group and the high and medium-dose with YOL group.The high and medium dose group with YOL raised SOD level and decreased MDA level in serum,and also ameliorated myocardial pathologic structure changes in acute ischemia rat. Conclusion: YOL preconditioning contributes to protective effect on acute myocardial ischemia in rats.

Abstract(2603) PDF (398KB)(324)
Abstract:
Objective: To establish a convenient and feasible animal model of vestibular dysfunction for pharmacodynamic study in mice. Methods: Both inner ears of the animals were intratympanically injected with 100 mg/mL solution of arsanilic acid for 0.05 mL. 3 days later,vestibular function was assessed by air righting reflex and contact righting reflex,as well as the head tilt and swimming behavior. Results: Correct landings rates of air righting reflex were decreased;time of contact righting reflex was prolonged;scores of head tilt and swimming behavior were higher than control. Conclusion: It is a convenient and feasible model of experimental vestibular dysfunction with injections of arsanilic acid in the inner ears of mice for research on pharmacodynamics of prophylactic drug for motion sickness and vertigo.

Abstract(1976) PDF (461KB)(161)
Abstract:
Objective: To establish an enriching technic process of total flavones from Herba Oxytropis Falcatae by macroporous resin. Methods: Zirconium oxychloride(ZrOCl2)chromatometry was used to determine the content of total flavones in samples.Dynamic state adsorbability,concentration and volume of adsorption stripping solvent,and the re-utilization of D-101 macroporous resin were studied. Results: The content of total flavones in enrichment is 26%,which was nearly five times of that before enriched. Conclusion: Chromatometry with zirconium oxychloride as developer is simple and credible.D-101 macroporous resin showed better adsorbability of flavones from the aqueous extract of Herba Oxytropis Falcatae with high re-availability,and 60%alcohol could be used as adsorption stripping solvent because it works quickly and efficiently.

Abstract(2139) PDF (482KB)(406)
Abstract:
Objective: To find a new way of improving the quality of TCM,blendings of crude Epimedium Brevicornum from various sources were studied according to their Fingerprints. Methods: Systematic optimization was adopted to determine the mixing ratio of different kinds of non-genuine crude drugs in order to maximize the similarity,which is based on the cosine value between the fingerprints of genuine and non-genuine crude drugs respectively.Fingerprints data were collected after the blending. Results: The similarity of drugs was improved evidently,and it was in accordance with the calculation result. Conclusion: Quality improvement of TCM can be made by blending.Optimized blending of crude drugs might be an efficient method in making full use of the relatively inadequate TCM resources.
