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 ...

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 ...

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...

INTRODUCTION Yeasts belonging to the genus Candida are responsible for the majority of fungal infections in humans. Candida tropicalis has been one of most commonly isolated non-albicans species. To analyze in vitro hemolysis promoted by clinical isolates of C. tropicalis obtained from blood and other clinical samples from hospitalized patients at the University Hospital of Londrina State Unive...

Incubation of a 0.5% suspension of washed, normal mouse erythrocytes with ferriprotoporphyrin IX (FP) at 37 degrees C and pH 7.4 caused potassium loss, swelling, increased susceptibility to hypotonic lysis, and finally hemolysis. Hemolysis was not inhibited by incubation in the dark, malonyldialdehyde was not produced, and various free radical scavengers had no effect on the hemolysis. Only the...

Results. In order to study the hemolytic activity of Streptococcus, α -, β - and γ -isolated from samples clinical material synanthropic birds rodents, we studied 324 cultures Streptococcus. rats, mice caught in livestock buildings -types hemolysis were mainly manifested, -hemolysis was observed less frequently. To properties 140 Streptococcus isolated air, washings walls floors, as well feeder...

The oxidative hemolysis of rabbit erythrocytes induced by free radicals and its inhibition by chain-breaking antioxidants have been studied. The free radicals were generated from either a water-soluble or a lipid-soluble azo compound which, upon its thermal decomposition, gave carbon radicals that reacted with oxygen immediately to give peroxyl radicals. The radicals generated in the aqueous ph...

To evaluate the occurrence of hemolysis during double-filtration plasmapheresis (DFP) treatment and its causes, we prospectively treated 113 myasthenic patients and monitored transmembrane pressure (TMP), arterial line pressure (Pa), and venous line pressure (Pv) at 30-minute intervals (M30, M60, M90, and M120) during treatment. Laboratory and clinical parameters related to the development of h...
