    Abstract ( 232 )   PDF (504KB) ( 195 )  
    ObjectiveTo discuss the effect of saikosaponin d on mice's acute toxicity. MethodsMice's acute toxicities of different drug-delivery ways were tested respectively by the classic methods of acute toxicity. ResultsCaculated by saikosaponind, the MLD of ig is 770.47 mg·kg-1·d-1, the LD50 of ip is 62.338 mg·kg-1·d-1, and the 95% confidence interval is 53.703~70.966 mg·kg-1·d-1. The main acute toxicity symptoms of mice are negligent action, then unsteady gait, shortness of breath,drooping eyelids,hair rising, intermittent convulsion, neurological inhibition by ig.The signs of dead mice are neurological inhibition, and eventually to death by ip. The surviving mice's weight gainings are slower in 14 d observation period and compared with the control group, there is no signifi cant difference. By anatomical observation of death mice, there are no other obvious abnormalities except hepatic pathological changes.ConclusionThe acute toxicity of saikosaponin d is high, and we further confirmed that saikosaponin d is one of mainly toxical material composition of bupleurum.The "dose-timepoison"relationships of accumulated toxicity, biotransformation process in vivo and in vitro, and the position and mechanism of toxic effects are to be further studied.

    2014, 11(12): 709-713. 
    Abstract ( 257 )   PDF (766KB) ( 206 )  
    ObjectiveTo study the protective effect of Yindan Xinnaotong capsule(YXC) on endothelial cells. MethodsHuman umbilical vein endothelial cells (HUVECs) were cultured in vitro and HUVECs were pretreated with 250 μg·mL-1,125 μg·mL-1 and 62.5 μg·mL-1 for 24 h. 200 μg·mL-1 Ox-LDL and 60 ng·mL-1 TNF-α were used to induce HUVECs injury. The cell survival rate was determined by MTT, and flow cytometry was used to detect apoptosis to evaluate the mechanism of protective function of YXC. ResultsThe maximal non-cytotoxic concentration of YXC was 500 μg·mL-1, thus 250, 125 and 62.5 μg·mL-1 were employed as the experimental concentrations. YXC could obviously increase the survival rate of HUVECs induced by Ox-LDL (P <0.05) and TNF-α with a dose-dependence manner; compared with model group, 62.5 and 250 μg·mL-1 YXC treatment decreased apoptosis rate induced by Ox-LDL HUVECs (P <0.05). Meanwhile, 250 and 125 μg·mL-1 YXC obviously reduced apoptosis rate induced by TNF-α (P <0.05). ConclusionYXC could protect the HUVEC injury induced by Ox-LDL and TNF-α, and this may be associated with the inhibitory effect on cell apoptosis.

    Effects of Paeoniflorin on ATPase and EAA in Gerbils with Cerebral Ischemia/Reperfusion Injury
    LI Dong-mei, CHE Wei, LI Xia, CAO Jun-ping
    2014, 11(12): 717-720. 
    Abstract ( 210 )   PDF (563KB) ( 175 )  
    ObjectiveTo investigate the effects of paeoniflorin (PAE) on gerbils with cerebral ischemia/reperfusion (CI/R) injury and the mechanisms involved. MethodsGerbil model of CI/R was prepared by bilateral common carotid occlusion for 10 min followed by 6-hour reperfusion. Then gerbils were divided into 5 groups at random (n=10), namely sham, model, PAE high, medium and low dose groups (20, 10 and 5 mg·kg-1, respectively). PAE was injected intraperitoneally(i.p.) for 3 days before the carotid occlusion. Stroke index was calculated during the reperfusion. The ATPase activities in brain tissue homogenate were examined by a phosphate assay and glutamate (Glu) and aspirate (Asp) contents were determined by HPLC. ResultsThe results showed that PAE significantly improved stroke index, compared to the model group (P <0.05 or P <0.01). PAE evidently elevated Ca2+-ATPase activities in brain tissue of CI/R gerbils (P <0.05). The Na+-K+-ATPase activities in PAE high and medium dose groups were significantly higher than the model group (P <0.05 or P <0.01). PAE markedly inhibited the Glu contents in brain tissue of CI/R gerbils (P <0.05 or P <0.01). However, PAE showed no influence on Mg2+-ATPase activities or Asp contents in brain tissue. ConclusionThe effectiveness of PAE pretreatment in CI/R injury appears to be associated with the enhancement of ATPase activities and inhibition of excitatory amino acid (EAA) toxicity in brain tissue.

    2014, 11(12): 732-738. 
    Abstract ( 337 )   PDF (661KB) ( 265 )  
    ObjectiveTo clarify the definition and scope of "adverse drug reaction surveillance". MethodsThe etymology, usages, and previous definitions of 'surveillance' were examined. The history and practice of adverse drug reaction surveillance was reviewed and a distinction among the concept framework of "adverse drug reaction surveillance","pharmacovigilance" and "pharmacoepidemiology" was made. ResultsThe targets of surveillance are harmful potentially; "ongoing","systematic", "collection", "analysis", "interpretation", and "dissemination" have been seen in any surveillance program. Surveillance starts as soon as the drug is first approved or at any time thereafter. The collected data involves not only the safety problems caused by the nature of the drug, but also related to drug standards, pharmaceutical production, drug storage and drug usages. Information technology has greatly promoted the surveillance. ConclusionDefinition of adverse drug reaction surveillance is proposed: A public health program aimed to adverse drug reactions, consisting of a set of processes for the ongoing systematic collection, compilation, analysis, interpretation of drug safety data(including relevant spontaneous reports, electronic health records, and experimental data), closely integrated with the timely and coherent dissemination of the results and assessment to those (including regulators, healthcare professionals and public) who have the right to know so that action can be taken. The purpose is to learn the distribution and trend of drug safety, to identify, evaluate, understand, and communicate the unexpected adverse drug effects, to perfect the drug benefit -risk profile, in order to prevent or mitigate the harmful effects of drugs.
