lb elucidate the relation of hematocrit (Hct) to the incidence of cerebral infarction, a prospective follow-up study of 16 years (1965-81) was performed in a general population sample of 1220 Hisayama residents aged 44 and over, of both sexes. Most of the subjects who died during the follow-up period were autopskd, the rate being 89.0%. Hct decreased with advancing age in men, but not in women....

Can Plasma Skimming or Inconstancy of Regional Hematocrit Introduce Serious Errors in Regional Cerebral Blood Flow Measurements or Their Interpretation? • Recent reports indicate that in cases of elevated plasma or blood viscosity, red cell velocity through the cerebral microcirculation is unimpaired while plasma transit is retarded. One explanation may be that plasma skimming is increased, wit...

We examined the pharmacokinetics of recombinant human erythropoietin (rh-EPO) in genetically anemic mice (W/Wv genotype) to clarify its disposition mechanism in hematopoietic injury such as occurs in aplastic anemia. After rh-EPO was administered to W/Wv and control (+/+ genotype) mice once a day for 1 week at different doses, both the hematocrit (Hct) and tissue uptake clearance (CLup) of 125I...

Two hundred thirty-three leopard frogs (Rana pipiens) from Oshkosh, Wisconsin, USA, were divided into two groups and their blood examined for trypanosomes. In Group I (n = 157), where the blood was examined by the hematocrit centrifuge technique (HCT), 36 (23%) were infected with trypanosomes. Eighteen were infected with Trypanosoma pipientis, 13 with Trypanosoma ranarum, three with Trypanosoma...

Blood oxygenation level dependent (BOLD)-based functional MRI (fMRI) is a widely utilized neuroimaging technique for mapping brain function. Hematocrit (HCT), a global hematologic marker of the amount of hemoglobin in blood, is known to impact task-evoked BOLD activation. Yet, its impact on resting-state fMRI (R-fMRI) measures has not been characterized. We address this gap by testing for assoc...

Aim: The present study aims to examine the effects of zinc deficiency on maternal and fetal outcomes during pregnancy. 
 Material-method: was carried out in a secondary care hospital between 2020 January December. Demographic data all patients, zinc, hemoglobin (Hb), hematocrit (Hct) levels at birth adverse pregnancy such as oligohydramnios, preterm delivery, preeclampsia, premature ruptur...

In cardiac surgery the substitution of lost blood volume by plasma substitutes is a common therapeutical approach. None of the currently available blood substitutes has a sufficient oxygen transport capacity. This can limit the functional integrity of the myocardium known as highly oxygen consumptive. The study was aimed to get information about the minimal hematocrit, also known as critical he...

Abstract Fescue toxicosis decreases beef cattle performance in a multitude of ways, including decreased health and immunity. Cattle challenged by fescue are often grazing an environment favorable for development gastrointestinal nematodes (GIN). Interactions parasite challenge may result further economic losses. Many producers treat animals regularly GIN parasites with little insight on necessi...

background: hemoglobin (hb) and hematocrit (hct) have been used routinely in the diagnosis of neonatal anemia and polycythemia.   objective: to measure the cord blood hb and hct and to determine their association with maternal hb and hct.   methods : 170 healthy neonates born through normal vaginal delivery with gestation age of 37-42 wks and birth weight of 2.5-4 kg, and their mothers were inc...
