1.Effects of Membranous Milkvetch (Astragalus membranaceus)on the Action of "Decoction of Invigorating Yang for Recuperation
Chinese Traditional and Herbal Drugs 1994;0(12):-
A stragalus membranaceus(AM ) plays an important role in the traditional Chinese recipe" Decoction of Invigorating Yang for Recuperation" (DIC ) as the main ingredient which invigorates Qi and promotes blood circulation. But in clinics,doses of AM used in tbe recipe of ten varies. For the purpose to investigate the effect of different doses of AM on the action of DIC, animal experiments were designed and studied. Rsults showed that when the doses of AM were 15 and 30g,the resulting DIC showed a better antiirritability,and enhancing immunity effects,as well as in vivo antithrombosis and vitro anticoagulation actions as compared to a dose of 120g AM in DIC (P

AIM: To establish the quality standard for Shexiangtongbi Babu plaster (Radix Astragali, Radix Angelicae sinensis, moschus, Commiphora myrrha, Resina Boswelliae Carterii, Radix Angelicae Pubescentis, Sanguis Draxonis, etc.) METHODS: Borneolum Syntheticum, Commiphora Myrrha, Radix Angelicae Pubescentis, Sanguis Draxonis, Radix Angelicae Sinensis were identified by TLC, and the content of Muscone was determined by GC. RESULTS: Borneolum Syntheticum, Commiphora Myrrha, Radix Angelicae Pubscentis, Radix Angelicae Sinensis could be identified by TLC. Muscone showed a good linear relationship at range of 0.026?g~0.078?g, r =0.9992. The average recovery was 97.57%, and RSD 1.50% respectively. CONCLUSION: The method is accurate and can be used to control the quality of Shexiangtongbi Babu plaster.

Objective To evaluate the effect of special rectification of clinical antimicrobial use in a hospital. Methods Medical records of patients receiving inguinal hernia repair before (in 2011)and after (in 2012)the per-formance of special rectification were reviewed,and the rationality of perioperative antimicrobial prophylaxis was compared.Results Prophylactic antimicrobial usage rate in patients receiving inguinal hernia repair decreased from 53.90%(76/114)in 2011 to 5.59%(10/179)in 2012,the difference was significant (χ2 =93.68,P <0.05);aver-age expense of antimicrobial use per patient decreased by 86.95% (from ¥ 624.73 in 2011 to ¥ 81 .52 in 2012);Combination use and single use was 93.42% and 80.00% respectively.Surgical site infection did not occur in both groups.Conclusion Through the special rectification activities of the clinical antimicrobial use,perioperative anti-microbial prophylaxis and expense of antimicrobial agents in patients receiving inguinal hernia repair is effectively re-duced.

The immune system is a complex system involving multiple organs,and it is vulnerable to age,gender,environment and other factors.For a variation normal physiological range,it is a great challenge to evaluate drug-induced immunotoxicity in preclinical safety study.Histomorphologic assessment of the immune system is a recognized cornerstone in the identification of immunotoxicity at present.In this paper,the principles of pathological evaluation for immune system,and pathological evaluation for important immune organs including thymus,spleen,lymph nodes are discussed briefly,so that it is intended to assist toxicity pathologists in the accurate and consistent characterization of intended and unintended drug-induced alterations of the immune system.

Toxicological pathology is a morphological elucidatet ion of tissue damage caused by drug toxicity,including damage type,location,severity grade and prognosis.It provides objective and accurate data to support preclinical drug safety evaluation.Therefore,toxicological pathology plays an important role in drug safety evaluation,and the pathologic data or conclusion often determines the termination or continuation in many drug development projects.In this paper,the characteristic of toxicological pathology,standardized management,the development of new techniques including in situ hybridization,laser scanning cytometry and laser capture microdissection,and related problems in pathology are discussed briefly.

OBJECTIVE: To establish a method for simultaneous determination of albiflorin, paeoniflorin, liquiritin, liquiritigenin, cinnamic acid, cinnamaldehyde, ammonium glycyrrhetate and 6-ginger phenol in Guizhijiashaoyao decoction. METHODS: HPLC method was adopted. The determination was performed on Kromasil C18 column with mobile phase consisted of acetonitrile-0.1% phosphoric acid solution (gradient elution) at the flow rate of 1.0 mL/min. The detection wavelengths were 235 nm(0-35 min,albiflorin, paeoniflorin, liquiritin)、280 nm(35-65 min,liquiritigenin, cinnamic acid, cinnamaldehyde, ammonium glycyrrhetate and 6-ginger phenol). The column temperature was 25 ℃, and the sample size was 20 μL. RESULTS: The linear range of albiflorin, paeoniflorin, liquiritin, liquiritigenin, cinnamic acid, cinnamaldehyde, ammonium glycyrrhetate and 6-ginger phenol were 2.125-34.000 μg/mL(r=0.999 9), 28.700-459.200 μg/mL(r=0.999 7), 3.675-58.800 μg/mL(r=0.999 7), 1.235-19.760 μg/mL(r=0.999 8), 2.300-36.800 μg/mL(r=0.999 8), 0.955-15.280 μg/mL(r=0.999 7), 36.000-576.000 μg/mL(r=0.999 7) and 1.500-24.000 μg/mL(r=0.999 7), respectively. The quantitative limits were 0.135, 0.102, 0.096, 0.033, 0.013, 0.023, 0.663, 0.198 μg/mL; the detection limits were 0.041, 0.031, 0.029, 0.010, 0.004, 0.007, 0.201, 0.059 μg/mL. RSDs of precision, stability and reproducibility tests were all lower than 3% (n=6). The recovery rates were 97.47%-100.76%(RSD=1.33%,n=6), 98.15%-103.50%(RSD=1.82%,n=6), 95.65%-100.84%(RSD=2.38%,n=6), 96.75%-100.32%(RSD=1.31%,n=6), 95.88%-102.75%(RSD=2.52%,n=6), 95.63%-100.63%(RSD=2.00%,n=6), 96.78%-100.45%(RSD=1.35%,n=6), 95.71%-100.48%(RSD=1.80%,n=6). CONCLUSIONS: The method is accurate, reliable and exclusive, and suitable for simultaneous determination of 8 ingredients in Guizhijiashaoyao decoction.
