The Na-K ratio in plasma actually increased despite hemodilution. Muscle sodium, calcium and magnesium content declined (Fig. 3). The intracellular electrolyte concentrations were very low compared with those of
sham-operated controls.
When the electrolyte composition of the environmental water was
experimentally reduced by adding distilled water to the aquarium so that
the sodium concentration in the water was maintained below 60 $q/
liter, adrenalectomized eels failed to survive for more than one week after
operation. By this time the plasma sodium concentration was reduced to
less than 90 mEq/liter. In contrast, control animals can survive up to 3
months in this medium (Chester Jones et al., 1965b; D. K. 0. Chan et al.,
1967b; Henderson and Chester Jones, 1967).
In seawater, adrenalectomized eels also showed poor survival. They
can be maintained however in one-third seawater which is approximately
