The purpose of this study was to determine whether a simple noninvasive sweat collection method using skin patches would be useful in monitoring sweat Ca and to determine changes in dermal Ca loss during a bed rest study testing a resistive exercise

During spaceflight, skeletal unloading results in loss of bone mineral density (BMD). This occurs primarily in the spine and lower body regions. This loss of skeletal mass could prove hazardous to astronauts on flights of long duration. In this study

Data are reviewed from twenty-two astronauts from seven space missions in a study of red blood cell mass. The data show that decreased red cell mass in all astronauts exposed to space for more than nine days, although the actual dynamics of mass chan

The total-body red blood cell mass (RBCM) decreases during the first few days of spaceflight; however, the pathophysiology of "spaceflight anemia" noted on return to earth is poorly understood. In studies before, during, and after a 9-day mission we

Astronauts have a reduction in their red cell mass when exposed to microgravity. This is probably mainly due to a physiological response to decreased energy requirements. Further studies of erythropoiesis were carried out in microgravity on rats flow

Blood drawn before and after spaceflight from the nine Skylab astronauts showed a statistically significant increase in mean plasma thyroxine (T-4) of 1.4 microgram/dl and in thyroid-stimulating hormone (TSH) of 4 muU/ml. Concurrent triiodothyronine

An apparatus for the collection of urine at -19 degrees C from unrestrained small laboratory animals was developed. The cooling unit accommodated five rodent metabolism cages for the collection of urine volumes up to 50 ml per collection period. The

Methods have been developed which permit frequent repetitive blood sampling of rats without perturbing physiological parameters of interest. These techniques allow a comprehensive hematological study over several weeks, in individual rats, thus permi
