BACKGROUND Currently, various calculation methods for evaluating blood-loss in patients with total knee arthroplasty (TKA) are applied in clinical practice. However, different methods may yield different results. The purpose of this study was to determine the most reliable method for calculating blood-loss after primary TKA. METHODS We compared blood-loss in 245 patients who underwent primary...
Specific antibodies to human fetal hemoglobin were prepared and, after conjugation with a fluorescent dye, were used to determine the distribution of Hb F-containing cells in blood smears from normal adults and individuals with hereditary and acquired conditions associated with abnormal levels of Hb F. The mean proportion of F-cells in normal persons was 2.7% +/- 1.4%, with a range of 0.5%-7.0%...
BACKGROUND Hemoglobinopathies are the most common inherited diseases in southern China. However, there have been only a few epidemiological studies of hemoglobinopathies in Guangdong province. MATERIALS AND METHODS Peripheral blood samples were collected from 15299 "healthy" unrelated subjects of dominantly ethnic Hakka in the Meizhou region, on which hemoglobin electrophoresis and routine bl...
BACKGROUND Infants with congenital heart defects (CHD) are at risk for white matter brain injury. This novel rat pup model characterizes the systemic effects of intravasal cell-free hemoglobin and hyperoxia, hypothesizing that immature endogenous scavenging systems relate to increased vulnerability to conditions present during cardiopulmonary bypass (CPB). METHODS Plasma pharmacokinetics of c...
CASE DESCRIPTION A sample submitted for hemoglobin (Hb) evaluation on a 5-day-old premature male infant with intestinal perforation, intraventricular hemorrhage, anemia, and sepsis contained 61.1% Hb A, 23.7% Hb F, 2.1% Hb A2, and peaks of 8.2% and 5.2% in the P2 and P3 regions of the Bio-Rad Variant II HPLC thalassemia assay (Fig. 1). Isoelectric focusing showed Hb A, Hb F, Hb A2, and a band c...
The purpose of this study was to determine changes in hematological and plasma indices of Common Carp Cyprinus carpio with regard to age, sex and hormonal treatment. Sixty fish were used to assess the age factor. Also, 20 fish including female and male were assigned to determine blood indices with regard to sex and hormonal treatment. The pituitary gland extract was used as hormone for males an...
We have previously shown that coculture of human embryonic stem cells (hESCs) for 14 days with immortalized fetal hepatocytes yields CD34 cells that can be expanded in serum-free liquid culture into large numbers of megaloblastic nucleated erythroblasts resembling yolk sac– derived cells. We show here that these primitive erythroblasts undergo a switch in hemoglobin (Hb) composition during late...
Hemoglobin D a hemoglobin variant occurs in a group of asianpopulation particularly from india, Pakistan, Iran, Iraq. In india, it is mainly reported in north western states of Haryana, PunJab and Gujarat. In heterozygous form, Hb D disease is mild and causes subclinical jaundice. In heterozygous form, it can cause severe hemolytic anemia. Here we present a similar case of Hb D with hemolytic j...
The early identification of some clinically significant hemoglobinopathies and precise differentiation of hemoglobin variants are important to provide early comprehensive medical care to prevent some serious complications, assess prognosis and offer genetic counseling. A prospective study of 500 infants from South Western Maharashtra showed that 0.4% (4 in 1000) of them had detectable levels of...
