Hypotonic intravenous solutions in children

Expert Opinion on Drug Safety, 2004
The use of hypotonic intravenous solutions, especially 4% dextrose/0.18% saline, remains standard practice in many paediatric units in the UK. The practice of prescribing hypotonic intravenous fluids derives from the work of investigators in the 1950s, who produced arbitrarily-derived formulae for calculating the maintenance requirements for water and ...

Energetics and mechanics of frog skeletal muscle in hypotonic solution

American Journal of Physiology-Cell Physiology, 1986
Hypotonic 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.

Hypertonic and Hypotonic Solutions

, 1958
The 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 ...

Slow phase hemolysis in hypotonic electrolyte solutions

Journal of Cellular Physiology, 1975
AbstractWhen a population of erythrocytes is partially hemolyzed the time course of hemolysis can be divided into a fast phase and a slow phase. The slow phase occurs with both rapid and gradual addition of the hypotonic medium (rapid and gradual hemolysis).

Changes of platelet cell volumes in hypotonic solution

Thrombosis Research, 1983
Changes of platelet cell volumes in hypotonic solution were studied by the use of a new apparatus for cell volume analysis. Continuous mean cell volume analyzer (CMA) is a computerized instrument which continuously counts the mean cell volume and records the results. Moreover, it also shows patterns of expansion or shrinkage.

INTRAVENOUS INJECTIONS OF HYPOTONIC AND HYPERTONIC SOLUTIONS

Journal of the American Medical Association, 1935
Histologic studies of the central nervous system in dementia praecox have failed to reveal specific morphologic nerve changes. Such structural changes as may be present in this morbid condition are secondary. Quite constant, but by no means characteristic, are changes in the cerebral subarachnoid space.

A hypotonic storage solution did not prolong the viability of RBCs

Transfusion, 2000
BACKGROUND: 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, 1977
Incorporation 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, 1973
ABSTRACT 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 ...
