Osmotic hemolysis of chemically modified red blood cells.
T HE MECHANISM of osmotic hemolysis of red cells has been a subject for discussion for many years. Much of the discussion has centered on the question of whether hemoglobin diffuses out of the cell by way of a single large break in the membrane, or by way of many small openings. Kochen5 using light microscopy and a dye which formed a precipitate with hemoglobin, observed what appeared to be a s...
متن کاملMeasuring osmosis and hemolysis of red blood cells.
Since the discovery of the composition and structure of the mammalian cell membrane, biologists have had a clearer understanding of how substances enter and exit the cell's interior. The selectively permeable nature of the cell membrane allows the movement of some solutes and prevents the movement of others. This has important consequences for cell volume and the integrity of the cell and, as a...
متن کاملBlood sampling and hemolysis affect concentration of plasma metabolites.
Two experiments were carried out to reveal and quantify plasma metabolites that are sensitive to hemolysis and animal stress due to the blood sampling procedure (vein puncture vs. catheter). In Exp. 1, 48 sows were fed 4 diets either once (0800 h) or twice daily (0800 h and 1500 h) in a crossover design and blood was collected after restraint via vein puncture 1, 4, 11, and 23 h after morning f...
متن کاملHemolysis during leukocyte-reduction filtration of stored red blood cells.
Hemolysis has been reported in red blood cells (RBCs) that have undergone leukocyte-reduction filtration. This study investigated whether the age of RBCs or the filter type affected hemolysis. One hundred eighty units of RBCs (adenine-saline added) were leukocyte-reduced by filtration. At each of the 6 weeks of shelf life, 10 units were filtered with the "BPF4" filter, 10 units with the "Purece...
متن کاملBlood Flow, Negative Pressure, and Hemolysis During Hemodialysis.
Blood flow, measured by an ultrasound flowmeter, and the extent of hemolysis were assessed during a single, routine dialysis in 100 patients. Before and after the hemodialysis session, blood was drawn for measurements of haptoglobin (HPT), hemoglobin (HGB), albumin (ALB), and lactate dehydrogenase (LDH). The average values were as follows: pump speed 510 mL/ min, real blood flow 422 mL/min, art...
