Slices of rat cerebral cortex developed spontaneous paroxysmal discharges when superfused with Krebs medium containing zero Mg2+ or 50 microM bicuculline. In both situations, the N-methyl-D-aspartate (NMDA) antagonists APV, 100 microM, and ketamine, 100 microM substantially reduced the frequency of the paroxysmal events, the reduction being greater in zero(More)
Quantitative aspects of the potentiation of GABA and muscimol by benzodiazepines and barbiturates are reviewed, taking account of both electrophysiological and receptor binding data. It has been a consistent finding that barbiturates cause a greater maximal potentiation than do benzodiazepines. The steroid anaesthetic alphaxalone and some naturally(More)
The steroid derivative RU5135 has been tested for its ability to antagonize glycine and the gamma-aminobutyric acid (GABA) analogue muscimol on isolated preparations of rat optic nerve and cuneate nucleus, respectively. On the cuneate nucleus, RU5135 antagonized muscimol in a competitive manner with a pA2 value of 8.31. RU5135 shared a common site of action(More)
1. Several derivatives of pregnane and androstane that have hypnotic properties have been investigated for their ability to potentiate responses to the GABAA receptor agonist muscimol and to reduce the effect of the non-competitive GABAA antagonist picrotoxin. 2. Depolarizing responses to muscimol in slices of rat cuneate nucleus were potentiated most(More)
There is growing demand to contain health care costs and to reassess the value of medical services. The traditional hospital, academic, and research roles of the infectious disease (ID) specialist are threatened, yet there is an increasing need for expertise because of growing antimicrobial resistance and emerging pathogens. Opportunities exist to develop(More)
