Hematology and immunology studiesA coordinated series of experiments were conducted to evaluate immunologic and hemotologic system responses of Skylab crewmen to prolonged space flights. A reduced PHA responsiveness was observed on recovery, together with a reduced number of T-cells, with both values returning to normal 3 to 5 days postflight. Subnormal red cell count, hemoglobin concentration, and hematocrit values also returned gradually to preflight limits. Most pronounced changes were found in the shape of red blood cells during extended space missions with a rapid reversal of these changes upon reentry into a normal gravitational environment.
