hemoglobin values in 9550 mothers delivered in the ob. & gyn. dept. of amin medical center were studied. hemoglobin levels of less than 11gr/100ml which is usually considered to be to the lower limit of normal for pregnancy were found in 2410 patient (25.3%) this rate has been recorded to be 19-30 percent in the u.s.a., 36 percent in western venezuela, 57.4 percent in india and about 80 percent...

It is not known whether the activation of Na/H exchange by shrinkage in dog red cells is due to the packing of cell contents or a change in cell configuration. To make this distinction we prepared resealed ghosts that resembled intact cells in hemoglobin concentration and surface area, but had one-third their volume. A shrinkage-induced, amiloride-sensitive Na flux in the ghosts was activated a...

Aim:We aimed to investigate the prevalence of anemia at admission intensive care unit (ICU), association between and mortality, lengths stay in hospital ICU (LOS-H LOS-ICU) COVID-19 patients.
 Material Methods:We retrospectively analyzed data 288 patients who needed admission. Patients were divided into two groups: anemic nonanemic. Demographic data, labaratory findings admission, LOS-H LO...

Stimulation of the T3C12 clone of Friend erythroleukemia cells with 1.2% dimethyl sulfoxide (DMSO) results in progressive increase in the concentration of globin mRNA sequences in the total cellular RNA of treated cells, as measured by nucleic acid hybridization employing a globin cDNA probe. The greatest increment in the content of globin RNA occurs between 30 and 40 h after addition of DMSO. ...

Previous studies suggested that y87 Gln in hemoglobin (Hb) F is an important site for promoting inhibition of Hb S (cy#: polymerization by H b F. We engineered and isolated the double mutant ) using a yeast expression system and characterized polymerization properties of this modified tetramer in an effort to clarify the role of Gln at position 87 in inhibiting H b S polymerization. Electrop...

Hypoxic or anemic goats with the A hemoglobin genotype switch to the production of hemoglobin C, resulting in a reduced blood oxygen affinity. However, the physiologic consequences of this switch are not clear. We therefore studied the gas exchange properties of the two hemoglobin types. We found that purified hemoglobins A and C have very similar oxygen affinities and H+ Bohr effects, but in t...
