reticulocytosis/hemorrhage

Fetomaternal hemorrhage (FMH) refers to the entry of fetal blood into the maternal bloodstream before or during delivery. FMH of more than 30 mL occurs with the frequency of about 1/300. Fetal outcomes may be compromised by still births, hydrops fetalis, cardiac complications, and increased rates of

Eleven 6-month-old calves were tsetse fly challenged with a stock of Trypanosoma vivax (IL 2337) that causes hemorrhagic infection. The calves were randomly euthanatized every 4 to 6 days; two other calves served as controls. Peripheral blood changes included anemia, thrombocytopenia, and an initial

BACKGROUND The Duffy blood group (Fy) antigen functions as the receptor whereby the malarial parasite Plasmodium vivax invades reticulocytes. In this study, we evaluated an autologous blood donation model to measure Fy expression during the anticipated response to blood loss. OBJECTIVE This study

After massive hemorrhage, adult sheep with genotypically low potassium (LK) red cells temporarily produce high potassium (HK) cells with ouabain-sensitive K+ pump fluxes equivalent to mature HK red cells. In light of recent reports of different red cell volume populations accompanying the HK-LK

OBJECTIVE To describe the pharmacokinetic profiles of six different dosing regimens for epoetin alfa, and whether more rapid and robust reticulocytosis can be elicited with more frequent administration of epoetin alfa in anemic critically ill patients. METHODS Randomized, open-label, multicenter,

We describe two Japanese children with idiopathic pulmonary haemosiderosis (IPH), whose refractory haemorrhages were treated with an intravenous lipid emulsion containing dexamethasone (liposteroid). A 22-month-old boy and a 14-month-old girl have been observed with similar symptoms; periodic bouts

In bleeding induced anemia of rabbits an increase of creatine in the red cells occurred, which in some cases amounted to more than 5-times the normal concentration. In all but one case plasma creatine rose as well. Reticulocytosis, increased O2-consumption of the red cells and an increased level of

The effects of activated neutrophilic secretory products on marrow erythroblastic islet erythropoiesis and peripheral blood parameters were studied after experimental blood loss. The supernatant of activated neutrophils was demonstrated to potentiate erythrodieresis in early post-loss period. At the

Stimulated erythropoiesis and reticulocytosis can be induced by daily bleeding, or by phenylhydrazine (PHZ) treatment. We compared the in vivo effects of PHZ and bleeding treatment on haematological, energy and redox status parameters in red blood cells (RBC) of rats. The results showed that all

Reticulocytosis in rats was induced by repetitive bleeding. Both in the vitro and the in vivo studies showed that the detected reductive speed of methemoglobin of the bleeding group was faster than that of the control group at all time intervals. At the same time, the NADH-cytochrome b5

OBJECTIVE To evaluate the proportion of blood samples diagnosed with reticulocytosis without anaemia in cats and dogs and report the aetiology and mortality rate of affected animals. METHODS Retrospective multicentre study including haematological examination of 3956 cats and 11,087 dogs admitted to

Hematological and serum biochemical changes in response to hemorrhagic stress were determined in both sexes of juvenile and adult Coturnix coturnix japonica over 3 day period following a mechanical hemorrhage of 30% of the calculated total blood volume. There was an initial shift posthemorrhage

Recombinant human erythropoietin (EPO) is an effective and safe therapy for correction of anemia in end-stage renal disease (ESRD). Clinical trials reported to date suggest that EPO improves anemia in over 90% of hemodialysis patients with anemia (Eschbach 1989). Factors which have been identified

Sustained erythropoiesis and concurrent bone marrow hyperplasia are proposed to be responsible for low bone mass density (BMD) in chronic hemolytic pathologies. As impaired erythropoiesis is also frequent in these conditions, we hypothesized that free heme may alter marrow and bone physiology in
