[Effects of electric stimulation on circadian rhythm of plasma cortisone in soldiers].

Objective: To observe the effects of electric stimulation on the circadian rhythm of plasma cortisone in soldiers.

Methods: Electric stimulation or phototherapy was respectively performed in the popliteal region (behind the knee) of the soldiers at different time points and radio immunal assay was utilized to examine the plasma cortisone concentration.

Results: The plasma cortisone concentration exhibited obvious circadian rhythmicity.
