    Notes: Summary Postprandial coordination of antroduodenal motility partly takes place via intrinsic mural pathways. The nature and origin of these nerve fibers have not yet been clarified. In this investigation using fluorochromic substances injected into the antrum and duodenum it was demonstrated that common central neurons for the antroduodenal area exist in the vagal nucleus.

    Description / Table of Contents: Zusammenfassung Die Wirkung der Umgebungstemperatur (18°C oder 28°C) und des Fasergehalts in der Diät (g je kg Trockensubstanz (TS) niedrig - 68, mittel - 110, hoch - 157) oder des Proteingehalts (g je kg TS niedrig - 91, mittel- 171, hoch - 262) auf den Verdauungstrakt, die Darmmasse, den Energieumsatz und auf die mit der Na+, K+-ATPase-Aktivität zusammenhängenden Respiration von Duodenalmukosa und Leber wurde bei 72 Wistar-Ratten in wiederholten Experimenten untersucht. Der Gesamte und Quabain-sensitive (ein Maß der Na+, K+-ATPase Aktivität) O2-Verbrauch der Gewebe wurde in vitro polarographisch ermittelt (YSI-biologische Sauerstoff-Erfassung nach dem Clark-Meßprinzip). Die Wärmeproduktion (WP) intakter Tiere wurde über Respirationskammern mit offenem Gasaustausch erfaßt. Die bei 18°C gehaltenen Ratten wiesen im Vergleich zu 28°C eine höhere Darmmasse auf. Die Masse an leerem Dünndarm, Caecum und Colon stieg mit ansteigendem Fasergehalt in der Diät (P〈0.05). Die WP als Korrelat der umsetzbaren Energie war nur im 1. Experiment höher (P〈0.05) bei 18°C als bei 28°C. Bei niedriger Proteinstufe war die WP signifikant höher (P 0.05) als bei den anderen Stufen. Verglichen mit 28°C erzeugte 18°C einen ansteigenden Gesamt- und Quabain-sensitiven O2-Verbrauch in der Duodenalmukosa. Die Leber reagierte nicht auf Temperaturunterschiede. Jedoch war ihr Quabain-sensitiver O2-Verbrauch bei niedrigem Proteingehalt in der Nahrung höher (P〈0.05) als bei den anderen Varianten. Bei niedrigem Fasergehalt war der gesamte und Quabain-sensitive O2-Verbrauch der Duodenalmukosa höher als bei den anderen Fasergehaltsvarianten. Die In-vitro-Ergebnisse stimmten mit der WP und dem O2-Verbrauch intakter Tiere überein.
    Notes: Summary Seventy two Wistar rats were used in two repeat studies to investigate the effect of environmental temperature (18°C or 28°C) and increasing levels of dietary fibre (low, 68 g/kg DM; medium 110 g/kg DM; high, 157 g/kg DM) or protein (low, 91 g/kg DM; medium, 171 g/kg DM; high, 262 g/kg DM) on digestive tract, visceral organ size, energy metabolism, and respiration attributable to Na+,K+-ATPase activity in duodenal mucosa and liver. Total and ouabain-sensitive (a measure of Na+,K+-ATPase activity) O2 consumptionin vitro of tissues were measured polarographically using a Clark-style YSI biological O2 monitor. Whole body heat production (in vivo) was measured using open-circuit respiration chambers. The weight of the visceral organs was higher in rats housed at 18°C than at 28°C. The empty weight of the small intestine, caecum, and colon increased as the level of dietary fibre increased (P 0.05). Heat production as a proportion of metabolizable energy was higher (P〈0.05) at 18°C than at 28°C in the first experiment but this difference was not significant in the second experiment. Rats fed the low protein diet had significantly higher (P〉0.05) heat production than those fed medium or high protein diets. Compared to 28°C, environmental temperature of 18°C caused an increased total and ouabain-sensitive O2 consumption in duodenal mucosa. There was no significant effect of environmental temperature on total and ouabain-sensitive O2 consumption in the liver. However, ouabain-sensitive O2 consumption in liver was significantly higher (P 0.05) when rats were fed a low protein diet compared to the medium or high protein diet. Total and ouabain-sensitive O2 consumption increased in duodenal mucosa of rats fed low level of dietary fibre compared to the medium or high dietary fibre diets. Thein vitro results corresponded with the whole animal energy expenditure and O2 consumptionin vivo.

    Notes: Summary Bladder hyperreflexia was induced experimentally in pigs. As compared to controls 9 out of 10 obstructed pigs developed hyperreflexia. The hyperreflexia was reversible by relief of the obstruction in all cases. No controls developed hyperreflexia within the observation period. It is concluded that obstruction as a single factor can provoke detrusor hyperreflexia. The model is proposed for further morphological and pharmacological studies.

    Notes: Summary The peristaltic activity in 36 normal pig pyeloureters in 19 pigs was investigated during various steady flow rates. Flow rates of 2, 4, 6, 8, 10 and 20 ml/ureter/min resulted in a mean frequency of 4.5, 4.9, 4.4, 4.2, 4.2 and 5.1 peristaltic events/min respectively. The frequency of peristalsis was thus independent of flow rate and also of baseline pressure but showed a weak relation to the magnitude of the mean perfusion pressure. The peristaltic activity is generally constant at all physiological flow rates in the steady state. This standardized study therefore confirms previous observations in showing that urine transport mainly is regulated by changes in the bolus size.

    Notes: Summary To evaluate influence of age on symptomatology and objective parameters in benign prostatic hypertrophy, preoperative findings in 199 unselected patients during one year were analysed. Symptoms of bladder instability increased with age, as did incidence of uninhibited detrusor contractions and bladder trabeculation, whereas maximum urine flow and obstructive complaints decreased, although prostatic size was the same. In the oldest age groups only was increasing prostatic size associated with increasing bladder trabeculation. Age related changes in neurological control and in the structure of the bladder may be involved, and the present results suggest age to be an important factor in the interpretation of symptoms and objective findings in prostatic hypertrophy.

    Description / Table of Contents: Zusammenfassung Der Effekt der Prostaglandine E1 und F2α auf das Wachstum der Epidermis von Meerschweinchen wurde in vivo untersucht. Die Prostaglandine wurden intradermal injiziert; mit Tritium markiertes Thymidin wurde intraperidonial vor dem Töten der Tiere injiziert. Die autoradiographischen Daten (labelling indices) wurden bestimmt. Ein signifikanter Anstieg wurde 4 h nach der Injektion von PGE1 ermittelt, ein Effekt der mindestens 72 h anhielt. PGF2a-Injektionen hatten keinen Einfluß auf den L.I.
    Notes: Summary The effects of prostaglandins E1 and F2α (PGE1 and PGF2a) on the growth of guinea pig epidermis have been studied in vivo. The prostaglandins were injected intradermally into guinea pigs, and tritiated thymidine was injected intraperitoneally prior to sacrifice. The autoradiographic labelling indices (L.I.) were assessed and a significant increase was found 4 b after injection of PGE1-an effect which lasted for up to 72 h. PGF2a injections had no significant effect on the L.I.
