Introduction

The collected and shipped blood samples are exposed to a various extra-analytical factors prior to analysis. The aim of the study was to determine the stability of analytes in serum gel tubes and plain tubes exposed to a range of storage temperatures and times after centrifugation.

Materials and methods:

Fifteen healthy volunteers were recruited and venous blood was collected into four tubes, two with and two without gel separator. Analyzing the baseline samples in 30 min, all were stored at 4ºC or 24ºC for 6, 12, 18, 24, 30, 36, 48 and 72 hours and 1 week. Sixteen biochemical anaytes were measured on each sample. Variations remained under the desirable bias considered as clinically insignificant.

Results:

On day three, most analytes remained stable including albumin, protein, creatinine, cholesterol, triglycerides, gamma-glutamyl transferase (GGT), alkaline phosphatase (ALP), alanine aminotransferase (ALT), creatine kinase (CK), lactate dehydrogenase (LD) regardless of tube types. Glucose concentration decreased markedly (P = 0.001) beginning from the first hours of storage in plain serum. The stability maximized for the analytes including glucose, total bilirubin, urea nitrogen (BUN), uric acid stored at 4 ºC in gel tubes. Aspartate aminotransferase (AST) activity increased significantly (P = 0.002) up to 48-h, however bias was not significant clinically. High density lipoprotein (HDL) concentration was stable in gel tubes at 24 ºC, in plain tubes at 4 ºC stored up to 36-h.

Conclusion:

Serum gel or non-gel tubes might be used interchangeably for 11 analytes chilled or at 24 ºC, whereas some restrictions must be applied for glucose, AST, BUN, HDL, and uric acid.  相似文献

对二巯基苯促进的孔雀绿的芬顿降解(英文)     

马家海  杨维英  李向军 《中国科学院研究生院学报》2012,29(2):175-179

研究了对二巯基苯对染料的芬顿降解反应的影响.研究发现,对二巯基苯可以显著加速孔雀绿和罗丹明B等有机染料的芬顿降解,但是不能提高染料的矿化率.通过循环伏安和邻菲啰啉实验,确认对二巯基苯在芬顿反应中的助催化剂作用是通过加速Fe3+/Fe2+的循环实现的.将对二巯基苯和氢醌的助催化效果做了比较.  相似文献

刘建军  崔树林  文海燕 《山东体育科技》2012,34(1):22-26

目的：基于校园体育俱乐部为载体,考虑学生的体育锻炼兴趣,探讨本运动干预方案对高校肥胖男生身体形态指标、血液生化指标的影响;方法：18～20岁肥胖大一男生共35名,按照BMI和个人意愿分为运动干预组（NE）和对照组（NC）,NE组进行有组织的90天、运动量递减（1～30天,大运动量;31～90天,小运动量）的运动干预。分别于运动前、30天后和90天后进行体格测试和空腹血脂、血糖和胰岛素水平检测。结果：1）NE组学生BMI、体脂率、腰围在经过30天和90天两个阶段综合干预后显著下降（P〈0.05）,NC组则前后变化不明显;2）NE组学生血清TG水平在30天后和90天后均显著下降（P〈0.05）,血清TC水平在90天后显著下降（P〈0.01）,LDL-C水平在90天后均显著下降（P〈0.01）,NE组HDL-C水平则无显著性变化（P〈0.05）;3）NE组学生空腹血糖和血清胰岛素水平在30后及90天后均出现显著下降（P〈0.01）,NC组则变化不明显。结论：基于校园俱乐部为载体的本运动干预模式可以有效降低学生的肥胖程度,改善其身体形态、血液生化指标,具有增进身体健康的作用。  相似文献

Binding interactions of pefloxacin mesylate with bovine lactoferrin and human serum albumin     

Fan JC  Chen X  Wang Y  Fan CP  Shang ZC 《Journal of Zhejiang University. Science. B》2006,7(6):452-458

The binding of pefloxacin mesylate （PFLX） to bovine lactoferrin （BLf） and human serum albumin （HSA） in dilute aqueous solution was studied using fluorescence spectra and absorbance spectra. The binding constant K and the binding sites n were obtained by fluorescence quenching method. The binding distance r and energy-transfer efficiency E between pefloxacin mesylate and bovine lactoferrin as well as human serum albumin were also obtained according to the mechanism of Forster-type dipole-dipole nonradiative energy-transfer. The effects of pefloxacin mesylate on the conformations of bovine lactoferrin and human serum albumin were also analyzed using synchronous fluorescence spectroscopy.  相似文献   

磁铁矿中磁性铁含量测定的不确定度评定     

姚永生 《安阳大学学报》2013,(6):37-38,41

讨论了磁铁矿中磁性铁含量测量结果不确定度的多种影响因素,分析了测量结果不确定度分量的主要来源。并对它们进行了计算。通过比较得出,在测量磁铁矿中磁性铁含量的过程中,重复磁选磁性铁过程是测量结果不确定度影响最大的因素。其次是重铬酸钾标准溶液滴定消耗体积的不确定度所造成的测量结果不确定度的影响。通过测量国家一级标准物质GBW07272得出,当测得磁性铁含量为46．91％时,其扩展不确定度U=0．52％（k=2）。  相似文献
