Abstract
Summary
A simultaneous measurement has been made of lactic acid and pyruvic acid changes in the blood of neuropsychiatric patients before and after extreme muscular excitaion induced by electroshock therapy (EST). The blood lactic acid level of all patients following SST rose sharply to a peak (six times pre-shock level) within 3 to 5 minutes and then returned to the normal level after 1 to 11/2 hours. The blood pyruvic acid level of all patients rose immediately following EST for thirty seconds (4-6 mg %), then fell to a minimum (2-3 mg %) within 3 to 5 minutes and rose again to a peak three times the pre-shock level 20 min after EST.
