A combination of the stopped-flow technology with dual channel spectrofluorometry of Ca(2+)-indicators was utilized for the measurement of rapid Ca(2+)-signals in rat cerebral cortical synaptosomes evoked by K(+)-depolarization. There was no observable contribution of Ca(2+)-ions from intracellular stores to the rise in [Ca2+]i. The kinetics of the fast(More)
The ovulatory cycle of the domestic hen (Gallus domesticus) was postulated to be the result of the interaction of two independent systems. A circadian system ws postulated to control the restriction of ovulation to an 8-h period of the day under conventional 14 h light: 10 h dark regimes. The final phase of follicular maturation was postulated to commence(More)
A double blind study has been carried out on patients scheduled for appendicectomy. They were divided into two groups who were given diazepam as premedication either orally or intramuscularly. The clinical effects were measured with regard to anxiolysis, gastric contents volume and acidity. Orally premedicated patients were not significantly less anxious.(More)
Rapid Ca2+ signals evoked by K+ depolarization of rat cerebral cortical synaptosomes were measured by dual-channel Ca2+ spectrofluorometry coupled to a stopped-flow device. Kinetic analysis of the signal rise phase at various extracellular Ca2+ concentrations revealed that the responsible voltage-dependent Ca2+ channels, previously identified as P-type Ca2+(More)
Intramuscular methohexital sedation was retained as an easy and reliable method to sedate children for a C.T. scan. In this retrospective study of 50 cases of children aged from 2 months to 7 years all the children were administrated an oral premedication (diazepam: 1 drop/kg and atropine: 0.02 mg.kg-1) one hour before the scanner examination. Once in the(More)
Time-resolved fluorometric monitoring of rapid changes in intracellular Ca(2+)-concentrations [Ca2+]i was employed to analyze the effect of gamma-aminobutyric acid (GABA) on evoked Ca(2+)-signals in rat hippocampal synaptosomes. The inhibitory action of GABA was mimicked by Baclofen, the selective agonist for GABAB-receptors, and also by the nonhydrolyzable(More)
