RESUMO
Objective To study the joint effect of small dosages of Aspirin and compound Danshen dropping pills on type 2 diabetes(T2DM) patients'and impaired glucose tolerance(IGT) patients' hypercoagulation blood.Methods The study followed diagnostic standards for T2DM by World Health Organization (WHO) in 1999,and randomly selected two groups of clinical patients:one had 63 patients with IGT and the other contained 68 patients with T2DM.Both groups took compound Danshen dropping pills with the total dosage of 10 pills each time,3 times per day,for continuum of 3 months.After that both groups stopped medication for 7 days,then began taking Aspirin after meal,with the dosage of 100 mg per day,for a continuum of 3 month.After that both groups stopped the medication for 7 days,then both group continued to take same dosage of ASA with addition of compound Danshen dropping pills of total amount of 10 pills per each time,3 times per day,for acontinuum of 3 months.Each medication period (ev ery 3 months) was monitored for platelet count (PET),prothrombin time (PT),kaolin partial thromboplastin time (APPT),The effective rate of anticoagulation for both groups were then calculated.Results The difference of PT、APTT between before and after taking single dosage of ASA for patients with impaired glucose tolerance (IGT) was statistically significant (P＜0.05),while patients with T2DM had no significant difference before and after taking same single dosage of ASA.Similarly, both groups with single dosage of compound Danshen dropping pills had no significant difference between before and after taking the medication.However,the difference of PT、APTT between before and after taking the combination of Aspirin and Danshen dropping pills of both groups were statistically significant (P＜0.05).IGT group with single dosage of ASA had an effective rate of 71.4％ for anti coagulation,while T2DM group with the same dosage reached 23.8％.The IGT group with combinatory dosage of ASA and Danshen dropping pills reached an effective rate of 100％ for anticoagulation,while T2DM group with the same dosage was 86.7％.The difference between those effective rates of anticoagulation was statistically significant in different medicine takeways of two groups (P＜0.05).Conclusion The combinatory use of small dosage of Aspirin with compound Danshen dropping pills had evident effect to improve IGT and hypercoagulation blood of T2DM patients who had good control of their blood glucose.
RESUMO
Objective: To separate and determine two constituents of Danshensu and protocatechuic aldehyde in compound Danshen Dropping Pill. Methods: The chromatographic conditions were as follow: Nucleosil C18 column, a mixture of methanol-water-acetic acid glacial (19∶80∶1) as the mobile phase with a flow rate of 1 mL per minute and the detection wavelength at 279 nm. P-hydroxybenoic acid was used as internal standard. Results: The calibration curves were linear in the range of 10～80 mg/L (r=0.9995) for Danshensu and 2～16 mg/L (r=0.9996) for protocatechuic aldehyde . The average recovery of Danshensu and protocatechuic aldehyde were 99.4 %and 99.5 %respectively. Conclusion: This method is accurate, simple and convenient, rapid and reproducible and can be used for the quality control of compound Danshen Pill.
RESUMO
Objective: To establish a method for determining the contents of ginsenoside Rg1 and Rb1, notoginsenoside Rg1 in compound Danshen dropping pill by HPLC/ELSD. Methods: Ginsenoside Rg1 and Rb1, notoginsenoside R1 were pretreated with solid phase extraction(SPE). The extraction conditions were as follow: Hypersit NH2 column, acetonitrile-isopropanol-10mmol/L ammonium acetate( 15∶4∶1 ) as mobile phase (iced acetic acid adjusting pH as 5.0) and the flow rate at 0.6 mL/min. Results: The linear range was from 1.0 to 10.0?g for ginsenoside Rg1 and Rb1, and notoginsenoside Rg1. The average recovery was 95.3%～100.4%.The inter-day RSD and intra-day RSD were less than 2%and 4%respectively. Conclusion: The method is concise and accurate, and will be helpful for the quality control of Radix Notoginseng and its preparations.
RESUMO
AIM: To establish an HPCE method for determining the fingerprint of Compound Danshen Dropping Pill.(Radix et Rhizoma salviae miltiorrhizae,Radix et Rhizoma notoginseng,Borneolum Syntheticum) METHODS: A standard fingerprint was set up under following conditions: capillary,50 ?m (id)?50.0(eff.41.5) cm,uncoated;detector,UV 203 nm;injection,50 mbar(10 s);running voltage,20 kV;buffer,50 mmol/L sodium tetraborate and 50 mmol/L boric acid(pH 9.0,containing 30 mmol/L SDS) and acetonitrile(4∶1,v/v). RESULTS: Based on the fingerprints of 10 batches Compound Danshen Dripping Pills,an average electropherogram was used as the standard fingerprint,among which there were 14 characteristic peaks. CONCLUSION: The fingerprint analysis can be used for assessing the quality consistency of Compound Danshen Dropping Pill from batch to batch.
