Osmotic Regulation in Aquatic Animals
OSMOTIC REGULATION IN AQUATIC ANIMALS. By August Krogh. Cambridge: At the University Press; New York: The Macmillan Company. 1939, pp. vii + 242, $4.00. To the series of Cambridge Comparative Physiology monographs, Professor Krogh has added a treatise on "the relations between concentrations of solutions, inside and outside cells and organisms." As Professor Krogh points out, there are wide div...
متن کاملOsmotic and Ionic Regulation in Animals
preparation. Moreover, the strangeness of modern algebra is likely to wear off rapidly in the years ahead. Some of the contents of the first chapter, which is on set theory, are already included in the curriculum of grade schools, the earliest introduction often being made at the kindergarten level. For this and other reasons biologists should take the book seriously. This book is an excellent ...
متن کاملBrownian motion, hydrodynamics, and the osmotic pressure
It is shown that the osmotic pressure of a colloidal dispersion can be interpreted as the isotropic part of the macroscopic particle stress in the suspension. The particle stress is in turn expressible in terms of hydrodynamic interactions among the suspended particles. Thus, there is a completely mechanical definition of the osmotic pressure, just as there is for the pressure in a molecular fl...
متن کاملColloidal osmotic pressure in chronic subdural hematoma.
The colloidal osmotic and hydrostatic pressure of chronic subdural hematomas were measured with a manometer in 35 patients. Manometric measurement showed an increase in the hematoma fluid cor responding to 5% of the total hematoma volume. The maximum colloidal osmotic pressure of the hematoma fluid, as measured with a transducer, was 23 ± 12 mmHg (mean ± standard deviation). Hemor...
متن کاملPlasma colloid osmotic pressure in healthy infants
BACKGROUND The plasma colloid osmotic pressure (COP) plays a major role in transcapillary fluid balance. There is no information on plasma COP of healthy infants beyond the first post-natal week. The normal COP in healthy adult subjects (25 mmHg) is currently also applied as a reference value for healthy infants. This study was designed to test whether plasma COP values in healthy infants are t...
