BACKGROUND Preventative health services are a pediatric health care cornerstone, which strives to promote health and prevent illness and injury. In Israel, Maternal Child Health Clinics (MCHC) provide these well child services for ages 0-6 years. MCHC care includes physician visits; however, the physician's role is not well defined. The study purpose was to provide a basis for setting policies ...

Because of discrepancies between electronically and manually measured values of mean cell hemoglobin concentration (MCHC) encountered in studies of pathologic red cells, we studied the effect of cell water content on MCHC measurements by both methods. A series of red cell samples with varying water contents (54%-164% normal) were prepared from normal cells using the antibiotic nystatin. MCHC wa...

Mean corpuscular hemoglobin concentration (MCHC), a parameter that is reported as a part of a standard complete blood count by automated analyzer, is a measure of the concentration of hemoglobin in a given volume of packed red blood cell. Values of MCHC significantly above reference range are not physiologically possible due to limitations on solubility of hemoglobin. The high MCHC can give us ...

A B S T R A C T Mean cell hemoglobin concentration (MCHC) is thought to have an important influence in sickle cell disease, both through the strong dependence of sickling rates on hemoglobin S concentration, and through the profoundly limiting effect of high MCHC on the rheologic competence of oxygenated, irreversibly sickled cells (ISC). Recent studies have tested the ability of antidiuretic h...

KCl cotransport (KCC) activation by cell swelling and pH was compared in sickle (SS) and normal (AA) red blood cells (RBCs). KCC fluxes had the same relationship to mean corpuscular hemoglobin concentration (MCHC) in SS and AA RBCs when normalized to the maximal volume-stimulated (VS(max)) flux (MCHC < 270 g/L [27 g/dL]). Acid-stimulated (pH 6.9) KCC flux in SS RBCs was 60% to 70% of VS(max) KC...

Water soluble polymers such as Hydroxy Propyl Methyl Cellulose (HPMC), Poly Vinyl Pyrrolidone (PVP), Carboxy Methyl Cellulose Sodium (CMC Na), and Methyl Cellulose as well as in combination of varying proportions are used in this study for the protective coating of Microcrystalline Hydroxy Apatite Complex (MCHC). The objective of this study was to investigate the effect of aqueous film coating ...

We hypothesized that the deoxygenation-induced increase in cation permeability of sickle cells was related to mechanical distention of the membrane by growing HbS polymer within the cell. To test this hypothesis, we determined the effect of deoxygenation on cation fluxes in sickle cells under conditions that restricted or permitted extensive growth of polymer, producing different degrees of mem...

OBJECTIVES To evaluate the stability of complete blood count (CBC) parameters by measuring at multiple time points up to 72 h after venepuncture. METHODS 36 samples submitted for routine haematology were measured at 0, 8, 24, 48, 72 h. 18 samples were kept at room temperature (23-25 °C) and the other 18 at 4 °C. The stability of the CBC parameters was determined by comparing the results to th...
