Thermotolerance in chicken red blood cells studied by 31P NMR spectroscopy.

Chicken red bloods cells (RBCs) were used as a model for cell survival following hyperthermia of differentiated cells, with rat RBCs serving as controls. The purpose was to investigate whether cells heated at 51.5 degrees C with or without prior heat shock exhibited discernible differences in phosphorus metabolites, intracellular pH or Mg2+ using 31P nuclear magnetic resonance spectroscopy.
