A hypotonic storage solution did not prolong the viability of RBCs
Transfusion, 2000BACKGROUND: Hypotonic storage solutions and WBC filtration are both reported to improve RBC viability. This study tested the ability of an investigational hypotonic storage solution (AS‐24, Medsep Corp.) to extend the viability of liquid‐stored RBCs to 8 weeks.STUDY DESIGN AND METHODS: In a pair of crossover trials, 11 RBC units, WBC‐reduced by ...

Incorporation of [3H]UMP into yeast spheroplasts in a hypotonic solution
Experimental Cell Research, 1977Incorporation of radioactive UMP ([3H]-uridine-5′ monophosphate) into RNA was examined in spheroplasts of Saccharomyces cerevisiae in a hypotonic solution. The reaction, which also takes place in cells lacking mitochondrial DNA, is inhibited by ethidium bromide (EB) (250 μg/ml), requires divalent ions, and is only slightly affected by 50 μg/ml of α ...

Changes in structure of the disks of retinal rods in hypotonic solutions
Journal of Cell Science, 1973ABSTRACT Changes in isolated frog rod outer segments, suspended in hypotonic solutions, have been examined by light and electron microscopy. Swelling of the disk occurs in hypotonic solutions. When one half or more NaCl is omitted from the Ringer solution used for suspending the rod outer segments, swelling is accompanied by the ...

The kinetics of haemolysis of human erythrocytes in hypotonic solutions of glucose
Biochimica et Biophysica Acta (BBA) - Biomembranes, 1968Abstract 1. 1. A study has been made of the kinetics of haemolysis of human erythrocytes in hypotonic solutions of glucose and values are presented for the Arrhenius and Eyring parameters. 2. 2. Linear correlations between the activation parameters indicate that glucose-induced haemolysis kinetics conform with the compensation law and that ...

Lysis of Neonatal Human Erythrocytes in Hypotonic Solutions of Glucose
Biology of the Neonate, 2009The rate of lysis of neonatal and adult human red cells in hypotonic solutions of glucose 0.116 and 0.118 m is examined, using an automatic procedure (Fragiligraph). The lysis of neonatal red cells is similar to the lysis of adult red cells. The decrease in osmotic concentration of D-glucose solution induces an increase in the rate of lysis more ...

Energetics and mechanics of frog skeletal muscle in hypotonic solution
American Journal of Physiology-Cell Physiology, 1986Hypotonic solutions are known to potentiate muscle force production and increase actomyosin ATPase activity in solution. As such, both the rate and amount of ATP hydrolysis should increase during contraction. This was tested indirectly by measuring force and energy liberation in Rana pipiens semitendinosus muscles at 0 degrees C in hypotonic solution.

Mast cell tumour destruction in dogs by hypotonic solution
Journal of Small Animal Practice, 1995ABSTRACTDistilled water was studied as an hypoosmotic oncolysis agent to prevent mast cell tumour (MCT) recurrence following surgical excision. The results from 118 MCTS excised in 74 dogs were: surgery alone, a recurrence rate of 52·6 per cent (10/19); and surgery followed by distilled water injections into the wound, a 26·2 per cent (26/99 ...

Selective detachment of mitotic cells by hypotonic salt solution
In Vitro, 1973A method has been developed to obtain synchronous populations from a human cell line which previously resisted the use of the selective harvest technique. A concentration of Colcemid was determined which reversibly enriched the mitotic population but avoided delays in cell cycle progression.

Hypertonic and Hypotonic Solutions
1958The colloidal behavior of protoplasm follows a queer pattern. One surprising and rather striking fact is that agents which might presumably be supposed to act in opposite fashion often enough have the same sort of an effect on protoplasm. So for example, cold and heat both can liquefy, both can coagulate protoplasm, both can act as stimulating agents ...

Stimulation of the Na+ pump by hypotonic solutions in skeletal muscle
Biochimica et Biophysica Acta (BBA) - Biomembranes, 1978The fractional loss of 22 Na+ from frog sartorius muscle is increased when the tonicity of the external solution is reduced. The effect, which is larger the lower the osmolarity, exhibits the following characteristics: (1) quick onset and reversibility, (2) is not reduced in the absence of external Na+, (3) is completely abolished by strophanthidin (3.
