gamma-Amino-beta-[3H]hydroxybutyric acid ([3H]-GABOB) was formed in rat brain from 2-[3H]-hydroxyputrescine that had been chemically synthesized from 2-oxoputrescine and [3H]sodium borohydride. After the injection of 2-[3H]hydroxyputrescine into the lateral ventricle of a rat brain, the rat was killed and then the...

Effects of GABOB on experimental induced epileptiform activities. Antiepileptic activity of gamma-amino-beta-hydroxybutyric acid (GABOB) has been tested on different models of either generalized or focal epilepsy induced by penicillin in cat. In acute experiments, topical application to the cortex of...

Total seizure frequency was evaluated among adult patients with severe partial epilepsy refractory to medical treatment. Clinical status was assessed before, and after a synthetic analog of gamma-amino-beta-hydroxybutyric acid (GABOB) was used as add-on therapy. Twenty-five patients with temporal and...

SART-stressed (repeated cold-stressed) rats, experimental model animals for vagotonic-type dysautonomia, have been reported to show EEG with lower-amplitude fast waves during resting-arousal and higher-amplitude slow waves during slow-wave sleep compared to normal rats. In this report, the effects of certain...

The cardiovascular effects of i.v. gamma-amino-beta-hydroxybutyric acid (GABOB) were investigated in rats anaesthetized with urethane. GABOB produced a dose-dependent hypotensive response. Treatment with GABA-A receptor antagonists prevented the GABOB response while the GABA stimulation by diazepam enhanced this response. The...
