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.

Hypotonic solutions induce epithelium-dependent relaxation of isolated canine bronchi

Lung, 1992
The present study was designed to investigate the effect of changes in osmolarity on the modulatory role of the respiratory epithelium on the underlying smooth muscle. Canine bronchial segments with or without epithelium were perfused intraluminally with modified Krebs-Ringer bicarbonate solution.

Hypotonic solution decreases serum sodium in infants with moderate bronchiolitis

Acta Paediatrica, 2013
AbstractAimTo investigate the influence of hypotonic parenteral hydration on serum and urinary sodium and osmolality in infants with moderate bronchiolitis.MethodsWe studied 36 infants (mean age 3.7 ± 2.3 months), with a diagnosis of moderate bronchiolitis admitted to a paediatric emergency unit in São Paulo, Brazil.

Why do bacterial protoplasts burst in hypotonic solutions?

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1969
Abstract A study of the relative effectiveness of sugars, of short peptides and of amino acids as osmotic stabilizers for nonrespiring Bacillus megaterium protoplasts indicated that the protoplast membrane could act as a porous differential dialysis membrane in much the same manner as cellophane membranes do and that its effective porosity increased ...

Lysis of Neonatal Human Erythrocytes in Hypotonic Solutions of Glucose

Neonatology, 1973
The 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 ...

Some unusual behavior of fish erythrocytes in hypotonic saline solutions

Comparative Biochemistry and Physiology, 1969
Abstract 1. 1. An unusual erythrocyte behavior in hypotonic saline solutions has been observed in several species of marine fishes. 2. 2. A relationship has been observed between osmotic fragility of fish erythrocytes and cell volume in certain species. 3. 3.

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.

Endothelial cell density in porcine corneas after exposure to hypotonic solutions

Graefe's Archive for Clinical and Experimental Ophthalmology, 2006
To evaluate exposure to sucrose solution (1.8%) and hypotonic balanced salt solution (BSS) for its effects on endothelial cell density of porcine corneas.Two groups of central discs from pig corneas were organ-cultured for 24 h. Twelve corneas per group were exposed to sucrose solution (1.8%) or hypotonic BSS for 4 min each.

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 ...

Acute Intraoperative Hemolysis Following Rapid Infusion of Hypotonic Solution

Laboratory Medicine, 1986
A patient undergoing intraoperative .radiation was noted to have marked hemoglobinemia and hemoglobinuria after the transfusion of 2 units of packed red cells. Laboratory investigation revealed no evidence of immune hemolysis, and the patient recovered uneventfully following diuresis.
