THE EFFECT OF CORTIN ON THE ELECTROLYTE CHANGES IN CAT MUSCLE DURING STIMULATION AND RECOVERY

Abstract

During a 30 min. stimulation period cat skeletal muscle loses about 20% of the K in the fibre, loses Mg, gains water along with NaCl and small amts. of Ca. With longer stimulation periods the electrolyte changes are increased, but in some cases water is lost from the muscle rather than gained. Intraven. KC1 increased the loss of K and the gain of water by the muscle during stimulation; intraven. CaCl2, and also intraven. cortical hormone, had depressing effects on the electrolyte changes.
