The enzyme activity of phosphoglucomutase (PGM) has been investigated in red cell haemolysates from 142 individuals and compared to the sub-type as determined by isoelectric focusing. The 10 phenotypes showed significant differences in PGM-activity which indicates that there is a correlation between the level of activity and the isolelectric point of homozygotes. No indication of silent alleles or alleles with reduced activity was found in this collective. 相似文献

The Tax Reform Act of 1986 rewrote the federal income tax code, bringing it closer to policy professionals' vision of what constitutes an equitable and efficient income tax. Research on tax compliance suggests the law might have affected taxpayer compliance in three ways: by reducing opportunities to overstate deductions, by changing perceptions of fairness, and by altering tax liabilities. Changes in taxpayer perceptions, attitudes, and noncompliance intentions were examined in three bodies of survey data, each containing pre-and post-reform data from independent samples of the same population. The results show an improved normative climate for taxpayer compliance and point to both the feasibility and the importance of examining the effects of substantive tax policies on taxpayer perceptions, attitudes, and behavioral intentions. 相似文献

Acknowledging Spain's diversity, this article assesses the impactof nationalism, regionalism, and other factors on public opinionabout the country's young democratic institutions. Utilizingsurvey data, the analysis focuses on national and regional variationsin public preferences for central state institutions and federalistor other designs for state-regional relations. It concludesthat a strong base of support exists for the current democraticsystem and the institutions through which it is implemented.Nevertheless, some doubts remain about the basic state structureof central-regional relations. 相似文献

冠心病猝死心肌肌动蛋白缺失的免疫组织化学定量研究 总被引:3,自引:0,他引:3
应用免疫组织化学LSAB法和图像处理系统,对德国慕尼黑大学法医学研究所1994年尸检冠心病猝死和对照组病例(各15例)的心肌肌动蛋白缺失情况进行定量研究。发现冠心病猝死病例心肌纤维内有明显的肌动蛋白缺失,是大小不一,多发、散在分布;对照组无或仅局限性小灶状缺失。将检测结果定量分析比较,其差异非常显著,说明重度冠状动脉粥样硬化患者是否冠心病猝死,其心肌肌动蛋白缺失的范围和程度有明显差异,冠心病猝死和对照组病例心肌肌动蛋白缺失的差异具有诊断意义,而形态定量分析能较客观准确地反映心肌纤维内肌动蛋白缺失量的变化。 相似文献

Correlation between plasma and bone marrow tricyclic antidepressants has not been studied before. Two groups of rabbits were given 10 and 20 mg of desipramine/kg body weight, respectively. Desipramine was administered to the animals once daily by mouth for 5 days. On the fifth day the animals were sacrificed and blood and bone marrow samples were collected and analyzed using a high performance liquid chromatographic (HPLC) method. Data showed that a correlation exists between bone marrow and blood desipramine. The bone marrow desipramine concentration increased as its blood levels increased. The average ratio of bone marrow to blood desipramine +/- S.D. (standard deviation) in both dosage groups was 37.2 +/- 4.46 with a range of 30.99-44.82. This investigation is promising and shows that bone marrow could be used as an alternative tissue in the absence of a suitable blood sample. 相似文献
