BACKGROUND Cardiopulmonary bypass (CPB) impairs intestinal barrier function and induces systemic inflammation after cardiac surgery. The objective of this study was to evaluate the effect of profound haemodilution (haematocrit 19-21%) during normothermic CPB on gastrointestinal permeability and cytokine release in comparison with a standard haemodilution (haematocrit 24-26%). METHODS This was...

to describe the relationship of blood lead levels (bll) and blood, δ-aminolevulinic acid dehydratase(alad) activity and haematocrit value(hct) to menopause , were examined 17 pre-or perimenopausal (prem) and 17 postmenopausal women (posm)from prishtina city, the capital ofrepublic kosovo. the mean age of the prem women was 28.8 years (21-46), with a mean blood lead level of 1.2 μg/dl (sd=0.583 ...

Previous preliminary results have shown an overnight decrease in haematocrit and red cell count after the first night of treatment with nasal continuous positive airway pressure (CPAP) in obstructive sleep apnoea (OSA) patients. The present study was designed to confirm these preliminary data, and to analyse the long-term effects of CPAP. The haematocrit and red cell count (RCC) were measured i...

While pre-eclampsia is the most common complication of pregnancy, a definitive screening test for early diagnosis is still elusive. In this study, haematocrit value was assessed as a screening test for pre-eclampsia in 660 women at 24-28 weeks of pregnancy attending a hospital in Tehran, Islamic Republic of Iran. Mean haematocrit values were significantly higher in pre-eclamptic than non-pre-ec...

Serum erythropoietin (S-Epo) was measured with a radiommunoassay method in 36 patients with polycythaemia vera, 17 patients with secondary polycythaemia and 14 patients with relative polycythaemia. The diagnoses were made without the aid of the S-Epo values. It was found that Sment to normal haematocrit levels. the S-Epo levels remained subnormal in most of the polycythaemia vera patients even ...

BACKGROUND Erythropoietin (EPO) may improve cardiac function and induce neovascularisation in experimental models of chronic heart failure (CHF). However, the increased haematocrit associated with EPO treatment might exert concomitant deleterious effects. AIM To investigate the haematocrit independent effects of EPO on cardiac function. METHODS AND RESULTS Rats underwent permanent coronary ...

The study was carried out on 30 clinically healthy dogs of various breeds. Haemoglobin concentration, haematocrit, platelet count and platelet haematocrit were significantly lower in citrate blood than in tripotassium ethylenediaminetetraacetic acid (EDTA-K3) blood. The study confirmed the limited usage of sodium citrate in haematology analysis, unless canine EDTA-dependent thrombocytopenia is ...

INTRODUCTION This study aimed to determine the prevalence of intestinal helminths, risk factors and haematocrit values among primary schoolchildren. METHODOLOGY Across-sectional study was conducted in 12 primary schools in March 2011. Stool samples were randomly selected from 778 children and were microscopically examined using Kato-Katz and formal-ether concentration methods. Haematocrit val...

AIMS To test whether cardiac output acts as a compensatory response to changes in haematocrit. METHODS A cohort of 38 preterm infants (27-31 weeks' gestation) was studied with repeated Doppler measurements of left ventricular output during the 1st month of life. Red blood cell transport was calculated when the duct was closed. RESULTS Multiple regression analysis showed that left ventricula...
