[Change in the total potassium content, hemoglobin volume and bromine space in Soiuz-14 crewmembers]

The specific factors of the 15-day space flight caused the predominance of catabolic over anabolic processes. This was equally true of tissue proteins and hemoglobin. Red blood cell and hemoglobin losses developed in parallel. They were more pronounced in the flight engineer than in the commander. No significant signs of body dehydration were noted.
