[Influence of posture changes on oncotic pressure and RHE proteinaemia (author's transl)].
Variations in proteinaemia levels in healthy man from posture changes or from physical exercise, as well as their chemical and physical consequences in plasma colloid-osmotic pressure, have been studied. Proteinaemia and oncotic pressure were measured in ten young males while lying flat, walking about, standing up motionless at attention and once again in a lying flat position. Proteinaemia and oncotic pressure increased on changing from a lying posture to orthostatism. The increase was much greater when the subjects were kept at rigid attention. Walking about did not produce any significant changes independently of the time factor. A significant correlation between changes in oncotic pressure and proteinaemia was always present. Changes in the oncotic pressure, however, were statistically more important.
