RT—PCR方法在小鼠肝炎病毒检测中的初步应用

采用4株小鼠肝炎病毒,MHV1、MHV3、A59和JHM的混合液人工感染SCID小鼠,接种病毒后1、2、5d分别取小鼠的全血、肝、肺、脑、脾和血清,用组织总RNA抽提试剂盒提取各组织的总RNA,然后用RTPCR方法检测小鼠肝炎病毒,并对各反应产物进行平均光密度测定。结果显示,接种后24h即可检测出血液中的小鼠肝炎病毒,病毒在小鼠体内各脏器出现的先后顺序为血、肝、脾、肺、脑,主要在肝脏进行复制。

Imidapril treatment improves the attenuated inotropic and intracellular calcium responses to ATP in heart failure due to myocardial infarction

1. Adenosine 5'-triphosphate (ATP) is known to augment cardiac contractile activity and cause an increase in intracellular Ca(2+) concentration ([Ca(2+)](i)) in isolated cardiomyocytes. However, no information regarding the ATP-mediated signal transduction in the myocardium in congestive heart failure (CHF) is available. 2. CHF due to myocardial infarction (MI) in rats was induced by the occlusion of the left coronary artery for 8 weeks. The positive inotropy due to ATP was depressed in failing hearts. Treatment of 3 weeks infarcted animals with imidapril (1 mg kg(-1) day(-1)) for a period of 5 weeks improved the left ventricle function and decreased the attenuation of inotropic response to ATP. 3. ATP-induced increase in [Ca(2+)](i) was significantly depressed in cardiomyocytes isolated from the failing heart and this change was partially attenuated by imidapril treatment. However, the binding characteristics of (35)S-labeled adenosine 5'-(gamma-thio) triphosphate in sarcolemma isolated from the failing heart remained unaltered. 4. ATP-induced increase in [Ca(2+)](i) was depressed by verapamil and cibacron blue in both control and failing heart cardiomyocytes; however, the ATP response in the failing hearts, unlike the control preparations, was not decreased by ryanodine. This insensitivity to ryanodine was attenuated by imidapril treatment. 5. Treatment of infarcted rats with enalapril and losartan produced effects similar to imidapril. 6. These findings indicate that the positive inotropic response to ATP and ATP-induced increase in [Ca(2+)](i) in cardiomyocytes are impaired in heart failure. Furthermore, blockade of renin angiotensin system prevented the impairment of the ATP-mediated inotropic and [Ca(2+)](i) responses in the failing heart.     

Study on chemical constituents of Folium Artemisiae argyi Carbonisatum,toxicity evaluation on zebrafish and intestinal hemostasis

Folium Artemisiae argyi Carbonisatum (FAAC) is a traditional medicine widely used in clinic. It has the effect of hemostasis by warming meridians. In order to further explore the chemical composition and biological activity of FAAC, the methanol extract of FAAC was isolated and purified by open column and high- performance liquid chromatography. and the complete structure was characterized by nuclear magnetic resonance (NMR) and LREI-MS for the first time, namely rutin, quercetin and octacosanol respectively. Initially the toxic effect of methanol extract of FAAC on zebrafish was evaluated by observing the phenotypic characteristics, spontaneous twitch times, heart rate, hatching rate, the distance of SV-BA and cardiomyocyte apoptosis of zebrafish. The results showed that FAAC has embryonic development toxicity and cardiotoxicity when it was higher than 62.5 μg/mL. Meanwhile, the hemostatic effect of methanol extract of FAAC was compared with FAA (Folium Artemisia argyi) by zebrafish intestinal bleeding model originally. The results showed that the hemostatic effect of the medium and high concentration dose groups (3.0 and 30.0 μg/mL) was enhanced for both FAAC and FAA. This study provided an experimental basis for the clinical application of FAAC.     

关于优良药房工作规范的探讨

优良药房工作规范(Good Pharanacy Practice,GPP)是药师在药房中实施“药学服务”(Pharmaceutical care)的行为准则,是衡量药师为病人或消费者服务质量的标准,也是药房自觉按照科学化、规范化和人本化管理的过程。     

《保健食品注册管理办法(试行)》的进步与不足

2005年6月2日,国家食品药品监督管理局以局令第19号的形式发布了《保健食品注册管理办法（试行）》（以下简称《注册办法》）,全文共九章,一百零五条,对涉及保健食品注册和审批的各个环节进行了界定.该办法于2005年7月1日起施行.本文试图对《注册办法》进行一些分析,在立法理念和立法技术层面上谈谈自己的一些粗浅看法。
