高血压患者血液流变学和血脂的变化及与高血压的关系 总被引:8,自引:0,他引:8
为探讨高血压、高血脂及血液流变学之间的相互关系,观察了264例高血压病人。与150例正常对照组进行比较,发现高血压患者的血液流变学各项指标及血脂中的TC和TG与正常对照组相比差异显著(P<0.01~0.05)。提示高血压、高血脂、高血粘度往往同时存在于高血压病人。认为血液流变学及血脂检查应作为高血压病人监测动脉粥样硬化的重要临床指标。 相似文献

高血压病患者的血液流变学观察 总被引:1,自引:0,他引:1
检测了40例高血压病患者和50例正常人的血液流变学指标。结果表明:红细胞刚性指数增大(P<0.05),红细胞聚集性增强和纤维蛋白原水平升高(P<0.01)是造成高血压病患者全血粘度升高和总外周循环阻力增大的重要因素。 相似文献

高血压、冠心病与高血脂症都直接危害人民的健康,高血压病还是发生中风最重要的危险因素之一。如何提高治愈率,减少中风的发生,已成为当务之急。基于此点,本文对以上三病种463例患者的血液流变学及血脂的测定结果进行了分析。结果表明:其血液流变学多项指标增高,与对照组相比有极显著性差异。三个病种的血脂也明显增高,含脂质高的血浆粘度也明显增高。提示临床在治疗上宜采用去脂,活血,降粘等综合治疗措施,预防与减少心肌梗塞与缺血性中风的发生。 相似文献

灵芝加降压药治疗难治性高血压时血糖、血脂、微循环和血液流变性的变化及意义 总被引:2,自引:0,他引:2
用各种血压测定法及活体微循环观察法发现,40例难治性高血压病人(治疗组27例,对照组13例)口服灵芝3个月后在大动脉血压、小动脉血压和毛细血管血压下降的同时,病人血粘度(高切、低切时的全血粘度及血浆比粘度)、红细胞压积和红细胞沉降率明显下降(P<0.05),甲襞微血管数增多、口径扩大、流速加快(P<0.05),血糖明显下降(P<0.05),但胆固醇、甘油三酯及高密度脂蛋白下降不明显(P>0.05)。上述变化间相关性不显著(P>0.05),说明上述改变是通过相互独立的途径取得。因而认为,灵芝对治疗高血压伴高粘血症和/或高血糖的病人尤为合适,且对预防或减轻高血压并发症有益。 相似文献

对27例左向右分流先天性心脏病病人及12例非癌症普胸病人,用放射免疫分析测定了血浆前列腺素E2(PGE2),结果发现先心病肺高压组病人的血浆PGE2(32.0±5.2ng/L),显著高于无肺高压组(23.0±4.4ng/L)及普胸对照组的(19.1±3.9ng/L);且轻度肺高压组(30.9±4.8ng/L)及中重度肺高压组(33.0±8.3ng/L)血浆PGE2均显著高于无肺高压组的,而轻度肺高压组和中重度肺高压组血浆PGE2比较,则差异不显著。先心病肺高压病人血浆PGE2的增加,可能是对肺动脉压力升高的一种代偿机制,而肺动脉高压的发病是代偿不全及其它因素作用的结果。 相似文献

ABSTRACT: In the previous paper we have demonstrated that progesterone-treated lymphocytes of healthy pregnant women produce a 34,000 MW protein that inhibits cytotoxic activity and prostaglandin F2α synthesis. Since recently it has been shown that certain leukotrienes have a stimulatory effect on natural killer activity, in this study an attempt was made to determine whether there is a relationship between cytotoxicity and PGF2α synthesis or if alterations in the values of these parameters are independent. Arachidonic acid increased cytotoxic activity of healthy pregnant women's peripheral blood mononuclear cells (PBMC) in a concentration-dependent manner. Exogenous arachidonic acid was able to counteract the blocking effect of the above-mentioned protein produced by progesterone-treated lymphocytes. To determine whether the products of the cyclooxygenase or the lipoxygenase pathway of arachidonic acid metabolism are responsible for increased cytotoxicity, both enzyme systems were blocked separately. Both indomethacin and the lipoxygenase inhibitor BW 755C reduced cytotoxicity in a dose-dependent fashion. However, the lipoxygenase inhibitor prevented prostaglandin synthesis to the same extent, or even more than indomethacin, in all concentrations used; so, its blocking effect cannot be considered as supportive evidence for the role of leukotrienes in cytotoxicity. On the other hand, lipopolysaccharide, with a selective stimulatory effect on prostaglandin synthesis, increased cytotoxicity. Lipopolysaccharide had no effect on progesterone-pretreated PBMC. The above data allow the assumption that besides leukotrienes, cyclooxygenase products may also increase cytotoxicity. 相似文献

Background and objective
Hypertension is one of the common medical complications of pregnancy and contributes significantly to maternal and perinatal morbidity and mortality. Uric acid (UA) is filtered, reabsorbed and secreted by the kidney. Thus, this study was conducted to assess the serum UA levels in PIH and to evaluate the diagnostic value of serum UA level in PIH.Materials and methods
This is a hospital based comparative cross-sectional study conducted in BPKIHS. Ninety study participants were included; forty five participants were diagnosed of PIH and forty five in control group after obtaining informed consent from study participants from August 2014 to May 2015. Serum UA was done by Uricase method and serum creatinine was done by Jaffe's alkaline picrate method in cobas c311 autoanalyser. Data were expressed in frequency, percentage, mean ± S.D., median (IQR), and Independent t-test, Mann–Whitney U test were applied. p Value <0.05 is considered to be significant.Results
Mean serum UA levels was higher in PIH compared to control group (5.46 ± 1.51 vs 4.03 ± 0.69) respectively. ROC curve demonstrated that serum UA showed a superior diagnostic efficiency (Sensitivity – 79.07%, Specificity – 71.19%) compared to creatinine (Sensitivity – 62.75%, Specificity – 27.45%) in PIH respectively.Conclusion
The present study shows that serum UA is significantly raised in PIH compared to the control group. Assessment of uric acid is a convenient and cost-effective method for determination of severity in PIH. Thus, serum uric acid can still be used as prevalent marker for risk assessment in PIH. 相似文献19.
