The actions of amylobarbitone sodium, butobarbitone and quinalbarbitone sodium upon insomnia and nocturnal restlessness compared in psychiatric patients

Amylobarbitone sodium, butobarbitone, quinalbarbitone sodium, and a placebo were compared in a controlled, double-blind trial in psychiatric patients with insomnia. An apparatus recording movement in bed is described, with sleep assessments by night nurses and patients. All three barbiturates significantly reduced movement and gave significantly longer, less broken and sounder sleep, without increased incidence of “hang-over.” There was no follow-on effect from night to night.

All possible basic methods of coding information for storage and retrieval are briefly described and contrasted. Another mathematical model for information retrieval based on linear graphs and stochastic ...
