BACKGROUND: Serum annexin A5 (anxA5) level is significantly increased in patients with acute coronary syndrome. Hematological indices are significantly increased in patients with ischemic heart disease. This study aimed to demonstrate the changes in the distribution of blood cells and the levels of anxA5 in patients presented with significant low ejection fraction ST-elevation acute myocardial infarction (STEMI) in comparison with corresponding patients with ischemic heart disease. METHODS: Patients with low ejection fraction presenting at Hospital of Diyala University of Iraq were enrolled...

Increased burden of advanced glycation end-products (AGEs) in case of hyperglycemic conditions leads to the development of retinopathy, nephropathy, and cardiovascular and neurological disorders such as Alzheimer's disease. AGEs are considered as pro-oxidants, and their accumulation increases the oxidative stress. The prolonged exposure to these AGEs is the fundamental cause of chronic oxidative stress. Abnormal morphology of red blood cells (RBCs) and excessive eryptosis has been observed in diabetes, glomerulonephritis, dyslipidemia, and obesity, but yet the contribution of extracellular AGEs remains undefined...

Anti-C, -Ce, -CD sera and monoclonal anti-C-antibodies with red cells varying by Rh-phenotypes comprising antigen C(w) have been studied. Four Rh-negative volunteer donors were reimmunized with antigens C and C(w). As shown by reactions of anti-C-sera, monoclonal antibodies anti-C with C(w)-positive cells, results of immunisation of the Rh-negative donors with antigen C(w) of Rh system, red cels containing Rh antigen C(w) contain also factor rh(C).

The sera of 390 pregnant Standardbred mares and 409 pregnant Thoroughbred mares were tested for anti-red blood cell (RBC) antibodies. Of the Standardbred mares and Thoroughbred mares, 20% and 10%, respectively, had anti-RBC antibodies detectable in hemolytic or saline agglutination tests. Most of the antibodies were specific for the CA blood-group antigen of horses. Other antibodies were specific for the Aa, Ab, Aa, Ab, Da, Df, Ka, Ua, or Qa blood-group antigens. The occurrence of these antibodies in the serum and colostrum was compared for 268 mares...

We performed fourteen experiments on sheep to determine whether or not erythrocytes tracer transport alters the calculated value of capillary tracer permeability surface area. In each set of experiments 14C-urea or 14C-thiourea was equilibrated with: (1) a whole blood sample; (2) saline alone, and (3) packed erythrocytes alone. Aliquots of each of these samples were injected separately into the superior vena cava of sheep and multiple indicator data collected from the aorta. Lung urea or thiourea microvascular permeability surface area (PS) was calculated for each set of data using the integral extraction method...

Inoculation of normal (CBA X C57BL/6)F1 mice with syngeneic, cellulose-conjugated serum globulin containing anti-SRBC antibodies (anti-SRBC Ig-cel) induced a specific reduction of the immune response to SRBC. This was observed in situ as well as in the adoptive transfer experiments. In the latter case, the animals injected with cellulose-conjugated globulin were the donors of lymphocytes. Furthermore, it was found that the serum from mice injected with an anti-SRBC Ig-cel complex contained anti-idiotype antibodies which inhibited the syngeneic and, to a smaller degree, the parental anti-SRBC antibody-forming cells and had no effect on AFC of some other strains...

In patients with early stages (I, II) of breast cancer we identified a subset of circulating lymphocytes that carry ferritin on their surface. No such lymphocytes were identified in normal women nor in women with benign breast disease. These cells did not form spontaneous rosettes with sheep red blood cells. Further studies revealed that in vitro treatment of the patients' lymphocytes with levamisole resulted n the removal of the surface ferritin and in an increase in the reactivity of the lymphocytes in mixed lymphocyte culture (MLC)...

The kinetics of autologous granulocytes, separated from whole blood and labelled with 111In-tropolonate with continuous maintenance in plasma, have been studied in man, using a gamma camera and computer, with the aim of quantifying the distribution of the marginating granulocyte pool (MGP). We have used 3 approaches: dynamic gamma camera imaging immediately following i.v. injection of labelled cells, comparison of the activity signal from 111In-granulocytes with that from previously injected 111In-labelled red cells and absolute quantification of 111In present in liver, spleen and blood...

The erythrocyte metabolism of two patients with nonspherocytic hemolytic anemia caused by a hexokinase deficiency, and a pyruvate kinase deficiency, respectively, were studied with NMR. The complexing of ATP and 2,3-diphosphoglycerate (2,3-DPG) with Mg2+ and hemoglobin (Hb) was determined using 31P-NMR on oxygenated and deoxygenated cells to investigate the influences of these enzyme defects on intracellular magnesium distribution and on Hb oxygen dissociation. In the pyruvate kinase-deficient red blood cells, the 2,3-DPG concentration was almost twice the normal value and the ATP concentration was near the lower limit of the normal range...

The spectrum of neurological complications associated with heroin addiction has changed in the past six years because of the progressive knowledge of the neurological complications related to HIV infection. We reviewed 48 heroin addicts with neurological complications and 452 heroin overdose who were seen in the Emergency Unit of our hospital during 1988 and the publications since 1967. Regarding the overdose we present the results of a prospective study leading to determine the causes. We emphasize the relationship with the level of total morphine in serum, instead of conjugate morphine, and with the presence of high levels of benzodiazepines found in the plasma rather than an hypothetic hypersensitivity phenomenon...

In the present study, we investigated the toxic response to repeated oral administration of 2-chloroethyl linoleate (2-CEL) in male rats at 250 mg/kg body weight for 2 weeks on alternate days (total 7 doses). Control rats received an equal volume of mineral oil. The five animals from each group were sacrificed on days 1, 7 and 28 following the last dose. No significant changes were observed in body weight, as well as organ-to-body weight ratios due to 2-CEL treatment. The red blood cell counts increased significantly in 2-CEL treated animals at day 28 as compared to the controls...

Normal peripheral human white blood cels (WBC) plated in agar culture generate colonies of blastoid cells when stimulated in vitro by phytohemagglutinin (PHA). Aggregates of PHA transformed cells are first visible by day 3-4. By day 7, the morphology of colonies becomes typical as clear discoid raspberry-like aggregates of 50-200 cells or more growing at or near the surface of the agar plate. Their dense arrangement and the coexistence within individual colonies of large and smaller cells are two main characterisitcs of these colonies...

Untreated African patients with essential hypertension were found to have high plasma sodium and low plasma potassium. The red cel contents of these cations determined from the same sample of blood were found to be high for sodium and normal for potassium. The passive permeability of the erythrocytes for potassium was lower in hypertensives than in controls. The ouabain-sensitive active sodium efflux was lower in hypertensives than in controls. The relationships between the erythrocyte cation content and the total body content of the cations, and between the membrane function in red cells and other cells of the body are discussed...
