## Abstract Cellular volume and potassium contents were determined in rat astrocytes from primary culture following suspension in isoosmotic (269 mOsm) and hypoosmotic (136 mOsm) phosphateβbuffered saline (PBS) containing various potassium concentrations. Within 1 min of suspension in hypoosmotic P
Intracellular changes of K f , Na', and Cl-were investigated by the aid of radiotracers in primary cultures of astrocytes when extracellular K f was (1) increased from 3 to 12 mM and subsequently again decreased to 3 mM; and (2) increased from 5.4 to 54 mM with subsequent decrease to 5.4 mM. In both
