  The effect of nifedipine on blood viscosity and hematocrit was investigated. Blood was sampled from eight patients with angina pectoris (mean age: 59 +/- 8 yr) treated with nifedipine (20-30 mg/day) for 5 months. Using a cone-plate type viscometer, blood viscosity was determined at the shear...

  Evidence for the usefulness of hydroxychloroquine as prophylaxis against thromboembolism after total hip replacement is examined. This agent causes reduction in red blood cell aggregation without prolonging the bleeding time in humans and, experimentally, reduces the size of the thrombus. There...

  Effects of echinocytosis on blood rheology and exercise performance were evaluated for 5 Thoroughbreds. Echinocytosis was induced by administration of furosemide (1 mg/kg of body weight, IM, q 12 h) for 4 days. Furosemide treatment resulted in decreases in serum sodium and serum chloride...

  The present study aimed at testing a possible relationship between hemorrheologic factors, such as hematocrit, fibrinogen, and whole-blood viscosity, and insulin sensitivity in healthy humans. Twenty-one 21-year-old men were studied with the hyperinsulinemic euglycemic glucose clamp technique. We...

  Prompted by evidence suggesting preserved red cell deformability in cardiac surgical patients pretreated with pharmacologic dosages of methylprednisolone, we performed in vitro experiments to examine the ability of similar levels of methylprednisolone and hydrocortisone to modify erythrocyte...

  Parathyroid hormone and calcitonin, both endocrine modulators of calcium homeostasis, may influence blood rheology. Parathyroid hormone is known to reduce erythrocyte survival, leading to anemia. Calcitonin has been found to have some vascular effects. We have analyzed the Influence ofparathyroid...

  Cognitive impairment is associated with increased blood concentrations of homocysteine and high blood viscosity. Previous studies have shown that vitamin B supplementation reduces homocysteine and enhances cognitive function in patients with mild dementia and low serum folic acid. However,...

  1. The shear stress of flowing blood profoundly influences the release of endothelium-dependent vasodilative and constrictive factors. Conversely, the influence of these mediators such as nitric oxide (NO) or endothelin-1 (ET-1) on blood rheology remains elusive. In the present study the...

  A study was carried out to investigate whether diltiazem influence blood rheology, as has been reported for some other calcium channel blockers. Twenty patients with clinical, stable angina pectoris were treated with 2 x 90 mg diltiazem per day for 2 weeks. Blood viscosity, plasma viscosity,...

  An encapsulated preparation of fish oil (Maxepa) was administered to hyperlipidaemic patients in order to establish the responsiveness of thecommon lipid phenotypes to dietary supplementation with n-3 fatty acids. 13 patients took 6 g/day of fish oil and 12 patients took 16 g/day in arandomized,...
