In vitro corrosion of Mg-Ca alloy- The influence of glucose content

引用

frontiers of Materials Science 2017年第3期11卷 284-295页

作者： Lan-yue CUI Xiao-Ting LI Rong-Chang ZenG Shuo-Qi LI en-Hou HAN Liang SONG College of Materials Science and engineering Shandong University of Science and Technology Qingdao 266590 China National engineering Center for Corrosion Control Institute of Metals Research Chinese Academy of Sciences Shenyang 110016 China

Influence of glucose on corrosion of biomedical Mg-1.35Ca alloy was made using hydrogen evolution, pH and electrochemical polarization in isotonic saline solution. The corrosion morphologies, compositions and structures were probed by virtue of SEM, EDS, fTIR, XRD and XPS. Results indicate that the glucose accelerated the corrosion of the alloy. The elemental Ca has no visible effect on the corrosion mechanism of glucose for the Mg-1.35Ca alloy in comparison with pure Mg. In addition, the presence of CO2 has beneficial effect against corrosion due to the formation of a layer of carbonate- containing products.

Development of forced degradation and stability indicating studies of drugs——A review

引用

Journal of Pharmaceutical Analysis 2014年第3期4卷 159-165页

作者： Blessy M Ruchi D.Patel Prajesh N.Prajapati y.K.Agrawal Department of Pharmaceutical Analysis Institute of Research and DevelopmentGujarat Forensic Sciences University Sector-18ANr.Police BhavanGandhinagar 382007GujaratIndia

forced degradation is a degradation of new drug substance and drug product at conditions more severe than accelerated conditions. It is required to demonstrate specificity of stability indicating methods and also provides an insight into degradation pathways and degradation products of the drug substance and helps in elucidation of the structure of the degradation products. forced degradation studies show the chemical behavior of the molecule which in turn helps in the development of formulation and package. In addition, the regulatory guidance is very general and does not explain about the performance of forced degradation studies. Thus, this review discusses the current trends in performance of forced degradation studies by providing a strategy for conducting studies on degradation mechanisms and also describes the analytical methods helpful for development of stability indicating method.

目的观察益肾固卫汤治疗慢性荨麻疹(CU)表虚证的疗效及安全性,并检测治疗前后血清补体(C)3、4水平变化,探讨益肾固卫汤对其免疫相关指标的影响及作用机制。方法将70例CU表虚证患者按随机数字表法分为治疗组35例和对照组35例。治疗组口服益肾固卫汤治疗,水煎服,每日服3次,每次150 mL;对照组口服枸地氯雷他定片和曲尼司特胶囊治疗。两组患者均以4周为1个疗程,共治疗2个疗程,观察两组患者的疗效、复发情况、不良反应及其治疗前后血清C3、C4水平的变化。结果治疗组总有效率87.88%(29/33);对照组总有效率84.38%(27/32),两组疗效比较,差异无统计学意义(Z=-0.685,P>0.05)。治疗后治疗组表虚证评分较治疗前显著降低(P<0.05),且治疗组较对照组降低明显(P<0.05)。治疗组治疗后血清C3水平较治疗前显著升高(P<0.05),与对照组治疗后比较,差异亦有统计学意义(P<0.05)。疗程结束后治疗组和对照组各有18、15例进行随访3个月,治疗组复发率为11.11%(2/18),显著低于对照组[53.33%(8/15)],两组比较,差异有统计学意义(χ^2=5.052,P<0.05)。两组均未出现严重不良反应。结论益肾固卫汤能明显改善CU表虚证患者的临床症状、升高C3水平,复发率低,且无明显不良反应,其作用机制可能与调整机体的免疫功能有关。
