Summary
-
1.
The electrolyte concentration and water content of plasma and muscle have been measured during adaptation to fresh water, after transfer from 300% sea water.
-
2.
The process of adaptation can be divided into three phases.
-
A.
The first hour after transfer are characterized by a rapid loss of electrolytes from plasma and muscle, and a decrease of water content in plasma, and increase in the water content of the muscle.
-
B.
The period 1 to 48 hours after transfer is characterized by a reduced loss of electrolytes, together with further increase of water in muscle.
-
C.
The period beginning 48 hours after transfer is characterized by an increase of electrolytes in plasma and muscle, together with decrease of water content in muscle, until equilibrium is reached.
-
3.
Changes in “Chloride space” and electrolyte distribution in muscle were also observed.
