in vitro antioxidant and erythrocyte protecting activities by aqueous extract of ficus thonningii leaves on blood cells were studied in acetaminophen treated rats. the extract was safe at limit dose of 5000 mg kg-1body weight. the extract demonstrated dose dependent antihemolytic effect at dose levels between 50 and 200 mg kg-1 body weight. the lowest antihemolytic effect was observed at dose l...

Chronic ethanol consumption leads to oxidative stress in the heart and erythrocytes of rats. As Ziziphus jujuba fruit has been shown to have potent antioxidants, such as flavonoids, we conducted this study to evaluate the effects of aqueous fruit extracts from Z. jujuba on rat hearts and erythrocytes following chronic ethanol consumption. Twenty-eight male Wistar rats were randomly divided into...

purpose: deformability/rheologic behavior of erythrocytes are related to near-surface membrane fluidity. specific agents can increase erythrocyte membrane fluidity in order to adjust hemodynamics in cardiovascular diseases. grapefruit flavanone naringenin has been proposed for potential use in an alternative therapy of cardiovascular conditions. in respect to this, we assessed here effects o...

the effect of long-term onion consumption on red blood cell antioxidant enzymes [glucose-6-phosphate dehydrogenase (g6pd), superoxide dismutase (sod) and glutathione peroxidase (gpx)], were measured. the relationship of these enzymes with pcv and hemoglobin (hb) concentrations was also determined. twelve adult female goats were used for the experiment and randomly assigned to three groups. anim...

Lichen aureus is a variant of pigmented purpuric dermatoses. The usual histopathology lichen characterized by subepidermal dense, band-like lymphocytic infiltrate, extravasated erythrocytes, and hemosiderin deposits. We report three patients with on the extremities similar clinical, dermoscopic, histopathological findings dense relatively deep dermal infiltrate accompanied extravasation erythro...

Long-term hypothermic storage of animal blood can lead to the loss its quality and cause complications in recipient animals after transfusion, so search for new methods increasing preservation erythrocytes continues. The article presents data ozonation effect on rate ovine human during with Alsever’s solution mannitol medium. Hemolysis, osmotic fragility distribution density by sphericity index...

Production of reactive oxygen species (ROS) and protein state membrane-cytoskeleton complex (MCC) in the erythrocytes, subjected to freeze-thawing with polyethylene glycol (PEG) subsequently transferred into physiological conditions vitro after cryoprotective agent removal were examined. Results SDS-PAGE β-mercaptoethanol showed a decrease spectrin content MCC profile cryopreserved erythrocytes...

Abstract Background and Aims The lifespan of erythrocytes in patients with renal anemia is shortened (∼70 days) compared to that healthy (120 days), but the pathological mechanisms causes are unclear. Senescent express phosphatidylserine (PS) on their outer membrane, which a signal for being removed by macrophages. PS localization cellular membrane mainly regulated two transporters: flippases s...
