    Notes: [Auszug] The experimental system has been described previously4. Excited states were produced by electron irradiation with a pulse of high energy electrons. Concentrations and kinetics of the transient species were established by optical absorption spectroscopy, and a pulsed dye laser and an optical ...

    Notes: Summary The kidney growth seen after the induction of experimental diabetes in rats has been compared to the compensatory renal growth after one-sided nephrectomy. After five days the kidney weight had increased from 650 ± 15 mg in a group of controls to 778 ± 21 mg in diabetic rats, and 764 ±17 mg in unilaterally nephrectomised rats. The increased weight was in both groups reflected in an increased DNA content and increased RNA/DNA and protein/DNA ratios. In a group of rats made diabetic and nephrectomised at the same time, kidney weight increased to 953 ± 22 mg after five days. When rats were unilaterally nephrectomised after 20 days of untreated diabetes, compensatory growth was much more pronounced than in non-diabetic rats, kidney weight rising from 780 ± 21 to 1144 ± 39 mg in five days. Similarly, in rats with established compensatory renal hypertrophy, diabetes induced a very rapid growth of the remaining kidney (1226 ± 46 mg after five days).

    Notes: Summary Streptozotocin diabetic rats have larger kidneys than non-diabetic rats. In the present study the rate of kidney growth during the first seven days of diabetes was correlated with the blood glucose concentration. Over a wide range of blood glucose concentrations (116–340 mg/100 ml) the kidney weight, protein content and protein/DNA ratio were closely correlated with the glucose values.

    Notes: Summary Normal and diabetic rats were given daily injections of human growth hormone for four days (5 mg per rat per day). Injected rats showed no differences from uninjected controls with respect to kidney weight or renal content of protein, RNA or DNA. Kidney weight increased by 7% after two days of diabetes and by 20% after four days, but growth hormone caused no augmentation of the hypertrophy. It is concluded that growth hormone plays no role in the initiation of diabetic renal hypertrophy.

    Notes: Abstract We report on a female newborn baby with a “myopathic” stiff face, open mouth, high-arched palate, microgenia, generalized muscular hypotonia, limited extension of elbows, wrists and knees, flexed adducted thumbs, velopharyngeal insufficiency, and hypertrichosis. Death occurred at 3 months due to respiratory insufficiency. Muscular biopsy revealed myopathic abnormalities.

    Notes: Summary Renal hypertrophy in rats with streptozotocin diabetes or after unilateral nephrectomy was studied by sterological techniques. — After 4 days of diabetes total glomerular volume had increased by 30%, and after 47 days by 43%. Glomerular growth was more pronounced than whole kidney growth during the first 4 days, but subsequently whole kidney growth exceeded glomerular growth. In control rats glomerular volume was 4.9% of total kidney volume; after 4 days of diabetes it was 5.4% and after 47 days 4.1%. — Proximal tubule length increased from 366 m/kidney in control rats to 447 m/kidney after 47 days of diabetes; tubular luminal diameter increased from 26.8 μm to 31.4 μm in the same rats. Tubular length and luminal diameter were, however, not increased after 4 days of diabetes. — In unilaterally nephrectomised rats there was no early rapid glomerular growth. Glomerular fractional volume was 4.9% in controls, 4.4% at four days, and 4.2% at 24 days after nephrectomy. — The results indicate a disturbed glomerulo-tubular balance in the early phases of diabetic renal hypertrophy.

    Notes: Summary Injection of porcine growth hormone (200 μg) or saline 5 days a week for 16 to 20 weeks in streptozotocin-diabetic rats showed that compared to saline growth hormone produced a 2 1/2-fold larger increase in glomerular capillary basement membrane thickness (2p=0.027). The possible significance of this effect of an elevated level of growth hormone for diabetic microangiopathy is discussed.

    Description / Table of Contents: Abstract Whereas 2.4 is likely to be an upper limit for the Dq/B-value of Cr(3)-complexes which show fluorescence the existence of a lower bound is rather unlikely. Experimental evidence suggests that the energy difference between the minima of the 2 E g- and the 4 T 2g-potential curves is one of the factors determining the relative intensities of phosphorescence and fluorescence.
    Abstract: Résumé Alors que 2,4 apparaît comme une limite supérieure du rapport Dq/B pour les complexes fluorescents de Cr(3), l'existence d'une limite inférieure est peu probable. L'évidence expérimentale suggère que l'intensité relative de la phosphorence et de la fluorescence est déterminée par la différence d'énergie entre les minima des courbes de potentiel des états 2 E g et 4 T 2g .
    Notes: Zusammenfassung Während 2,4 wahrscheinlich die obere Grenze für den Dq/B-Wert fluoreszierender Cr(3)Komplexe ist, gibt es für die Existenz eines unteren Grenzwerts keine Anzeichen. Experimentelle Ergebnisse legen nahe, daß das Verhältnis von Phosphoreszenz- zu Fluoreszenzemission durch die relative Höhe der Minima der 2 E g- und 4 T 2g-Potentialkurven bestimmt wird.
