    Notes: Summary The deposition rate of 2 tritiated odorants onto insect antennae of different sizes and shapes is linearly proportional to the product of odorant concentration times the antennal surface area. This result challenges an assumption in a commonly accepted hypothesis that sensillar shape affects odorant deposition and that a single odorant molecule can initiate an action potential in a receptor cell. Consequently the 1-molecule-1-spike hypothesis bears reinvestigation.

    Description / Table of Contents: Abstract Etomidate has become an important induction agent in high-risk patients because of its cardiovascular stability. Its unwanted side-effects such as pain on injection and thrombophlebitis could be significantly reduced by a new (medium chain triglyceride and soya bean) emulsion formulation. Propofol is solved in a mixture of long chain triglyceride and soya bean emulsion. In this double-blind, randomized study we compared the haemodynamic effects, the patients' sensations, signs of thrombophlebitis and postoperative nausea and vomiting (PONV) following injection of both drugs. Methods. Following premedication with 2 mg Lormetazepam p.o. in 50 patients per group, anaesthesia was induced with either 0.51 mg etomidate in lipid emulsion or 3.04 mg propofol per kg bw. No opioid or benzdiazepine was given i.v. before induction. After injection of the tested drug, the cannula was removed. Changes in blood pressure and heart rate were recorded as well as signs of discomfort during and after injection (pain, burning, tension, cold). Venous sequelae were assessed for 5 days after injection to register signs of thrombophlebitis. Results. Demographic data showed no difference between the two groups. After propofol more often a fall in blood pressure was seen. Pain (25 vs 1 pt), burning 19 vs 1), tension 15 vs 3), cold (35 vs 17) after injection was registered significantly more often in the propofol group, whereas myocloni predominated in the etomidate group (13 vs 6) P〈0.05, chi-squared-test). No difference was seen in PONV in either groups. Conclusion. Etomidate formulated in a medium chain lipid emulsion causes significant less discomfort for the patients than propofol, which is solved in a long chain formulation. Myocloni, however, occur significantly more frequently after etomidate than after propofol.
    Notes: Zusammenfassung Venenverträglichkeit, subjektives Empfinden, Kreislaufverhalten und postoperative Übelkeit/Erbrechen wurden nach Etomidat in einer neuen galenischen Zubereitung (Etomidat- ® Lipuro) und nach Propofol (Diprivan ® ) bei 100 Patienten miteinander verglichen. In einer randomisierten Doppelblindstudie erhielten je 50 Patienten ohne vorherige Gabe eines Opioids oder Benzodiazepins im Mittel 0,51 mg Etomidat oder 3,03 mg Propofol pro kg KG zur Narkoseeinleitung. Die Narkose wurde nach Vecuronium zur Relaxation mit O 2 /N 2 O (35:65) und Isofluran aufrechterhalten. Kreislaufverhalten und subjektive Mißempfindungen der Patienten (Brennen, Kälte, Druck, Ziehen) während der Einleitung wurden registriert. Postoperativ wurde die Injektionsvene über 5 Tage auf Zeichen einer Thrombophlebitis untersucht. Es zeigte sich nach Propofol häufiger ein Blutdruckabfall als nach Etomidat. Schmerzen, Kältegefühl, Brennen und Ziehen wurden signifikant häufiger nach Propofol geäußert, während Myokloni öfter nach Etomidat- ® Lipuro registriert wurden. Postoperativ zeigten sich nur geringgradig Verhärtung, Schwellung oder Rötung der Venen, ein Unterschied zwischen den Substanzen fand sich nicht. Postoperative Übelkeit und Erbrechen (PONV) waren mit 24% nach Propofol und 26% nach Etomidat- ® Lipuro nicht signifikant verschieden.

    Notes: Abstract Peaks in more than 5000 spike train correlograms, obtained from monkey striate cortex, were measured. Earlier work had shown qualitatively that there are frequent prominent peaks having widths in a range around 50 ms, and narrower peaks less than about 7 ms wide. Here we demonstrate that the distribution of peak widths shows a dichotomy.

    Notes: Summary Extracellular recordings were made from preoptic-anterior hypothalamic neurones with combined recording and iontophoresis electrodes. Short iontophoretic applications of β-alanine, GABA, glycine and taurine inhibited the discharge of the majority of neurones tested. Bicuculline methochloride reversibly and selectively antagonised GABA responses. Strychnine reversibly antagonised β-alanine, glycine and taurine but not GABA responses. These results suggest the existence of two populations of inhibitory amino acid receptors in the preoptic-anterior hypothalamus. The function of inhibitory amino acids in the rostral hypothalamus was briefly discussed.

    Notes: Abstract Four hundred and sixty-three new diagnoses of coeliac disease in children were made during 1973 to 1986 in our department. The distribution of new diagnoses per year did not show any decreasing trend in the period 1973 to 1986. No changing trend in breast feeding attitudes was found in the region during the same period. Analysis of the clinical pattern showed a constant distribution of age at diagnosis, onset of first symptoms and nature of symptoms throughout the period studied. These data suggest that coeliac disease is predominantly genetically determined and its expression is modulated by individual and environmental factors. The stability of the observed prevalence of the disease is parallel to the unchanging pattern of breast feeding attitudes in the region.
