THE SPECIFIC HEAT OF RED CELLS, WITH SPECIAL REFERENCE TO THE PARACRYSTALLINE RAT RED CELL
Eric Ponder 1
1 From the Nassau Hospital, Mineola, Long Island
The specific heat of the rat red cell, kept in cold sodium citrate, changes in the neighborhood of 6°C., the temperature near which the cell passes from its paracrystalline state to a state of greater disorder. The change in the specific heat is from 0.74 with a standard deviation of ±0.022 (paracrystalline state) to 0.87 with a standard deviation of ±0.021 (normal state).
Although it has been looked for, no evidence of a change in specific heat has been found, between 1°C. and 15°C., in the case of the human red cell or of the fresh rat red cell in saline or plasma.
