Effects of Injection of Analgetics and Alcohol Drinking on Values of Electric Flicker

Abstract

By means of Motokawa's method of electric flicker, we measured for 50 minutes the variation of electric flicker values of 9 subjects after opium alkaloid injections, of 3 subjects after analgetic (benadryl and phenobarbit-al) injection and of 5 subjects after 15% alcohol drinking. In some cases selective reaction time (SRT) was measured in parallel.
1. After the opium alkaloid injections and alcohol drinking, the values of EF and SRT increased gradually, reached a maximum about 30 minutes after an injection or alcohol drinking, and decreased to the initial value in about 60 minutes.
2. In case of benadryl and phenobarbital injections, no significant change of electric flicker values and selective reaction time could be found.
3. In some subjects the alcohol content of the blood was measured together with EF and it was found that both changed almost in parallel.
