Shape changes of GSH-treated human erythrocytes during the acidified serum test were examined by a differential interference microscope. A time-course study of the erythrocytes undergoing complement-mediated hemolysis revealed two kinds of hemolytic processes. One is rapid hemolysis, in which GSH-treated erythrocytes are transformed into spherical forms prior to hemolysis. The other process is ...

Bovine sera for tissue culture use were shown to contain heterophil antigen of the Paul-Bunnell-Davidsohn type by immune adherence hemagglutination tests with sera from patients with infectious mononucleosis. The antibody titers observed were comparable to those determined by two other methods; i.e., the immune adherence hemagglutination test was found to be as specific as the differential abso...

100 patients with beta-thalassemia trait, comprised of 55 men and 45 women, participated in a study to measure serum lipoproteins. the results were compared with the data obtained from 100 control subjects of the same age and sex. a significantly lower level of mean serum total cholesterol and ldl cholesterol, and a much higher level of hdl cholesterol were obtained in beta-thalassemia trait as...

The current study aimed to detect S.pneumoniae, which is one of the gram-positive bacteria that gives partial α-hemolysis on blood agar media, as well has ability complete hemolysis (beta)-hemolysis under anaerobic conditions. Fifty sputum specimens were collected from patients in Ibn sena and Al Salam hospitals Mosul/ Iraq august 2021 March 2022. Five isolates diagnosed S.pneumoniae exhibited ...

Background and Aims: Due to the shortage of donor livers, minor ABO-incompatible liver transplantations are commonly performed. Together with the allograft, immunocompetent B-lymphocytes, called passenger lymphocytes, are transplanted. In case of minor ABO-incompatibility, these passenger lymphocytes produce antibodies directed towards the recipient's red blood cells, which causes immune-mediat...

N ABNORMALITY of the red cells of paroxysmal nocturnal hemoglobinuria ( PNH ) is responsible for their short life span in the circulation anu their lysis in vitro by certain factors present in normal plasma or serum. The hemolytic system in vitro is characteristically more active when the serum is made somewhat acid, about pH 6.8. The addition of thrombin to the serum is also capable of increas...

Some animals routinely endure serious injuries from predators or during intraspecific territorial conflicts. Such is the case for Amphiuma tridactylum, an aquatic salamander that lives in an environment rich in potentially infectious microbes, apparently with rare or no pathogenic infection. Some vertebrates possess innate immune mechanisms, but whether this is the case for Amphiuma is unknown....

the oxidative hemolysis of rat erythrocytes induced by 2,2’-azobis–(2-amidinopropane) (aaph) and its inhibition by rosemary essential oil was studied. different concentrations (0.178, 0.357, 0.534 and 0.712 ml/ml) of the essential oil showed no significant hemolysis compared to phosphate buffer solution. aaph (25 mm and 50 mm) induced hemolysis in a time-dependent manner. diff e r e n t concent...

Hemolysis caused by flow in hypodermic needles interferes with a number of tests on blood samples drawn by venipuncture, including assays for metabolites, electrolytes, and enzymes, causes discomfort during dialysis sessions, and limits transfusion flow rates. To evaluate design modifications to address this problem, as well as hemolysis issues in other cardiovascular devices, computational flu...
