    Notes: Abstract The nuclide95Sr was isolated by chemical separation methods after thermal neutron induced fission of235U. It's decay properties were investigated employing semiconductor spectrometers and coincidence techniques. A half-life of 24.4±0.2 sec was found. Out of 29 gamma rays, 25 transitions representing 97% of the observed gamma-ray intensity were placed in a decay scheme comprising 19 excited states of95Y.

    Notes: Abstract The nucleide93Sr was isolated by chemical separation methods after thermal neutron induced fission of235U, and its decay properties were investigated employing scintillation and semiconductor spectrometers and coincidence techniques. A half-life of 7.43±0.03 min and aQ β-value of 4.3±0.2 MeV were found. Out of 74 gamma-rays, 55 transitions, representing 97% of the observed gamma-ray intensity, could be placed in a decay scheme comprising 22 excited states of93Y.

    Notes: Abstract The nuclide94Sr was isolated by chemical separation methods after thermal neutron induced fission of235U. Its decay properties were investigated employing semi-conductor spectrometers and coincidence techniques. A half-life of 74.1±0.3 sec was found. Besides the 1428.3 keV γ-ray we found 4 new γ-rays which could be placed in a decay scheme comprising three excited states of94Y. The 1+ states in theuu-nuclides90,92,94Y and88,90,92Rb are compared.

    Notes: Summary Experimental testicular torsion must be used for certain studies of clinical relevance, but most experimental models either do not provide hemodynamic alteration comparable to the clinical situation or cannot guarantee reproducibility. Using a rat model arterial perfusion and hemorrhagic infarction were correlated to the degree of both intra- and extravaginal testicular torsion. Arterial inflow was measured sequentially with radiolabelled microspheres, hemorrhagic infarction was judged by the increase of testicular weight. Maximal hemorrhagic infarction and reproducible values were found when the spermatic cord was twisted togehter with the tunica vaginalis for 360°–540°.

    Notes: Abstract The stimulatory effect of Nacom® (250 mg L-Dopa and 25 mg L-Carbidopa) on the HGH secretion was evaluated in 75 short stature patients. The number of blood samples was restricted to only three (0, 45 and 90 min). 63 patients reached adequate HGH concentrations after the ingestion of 1 tablet Nacom (84%). Somatotropin levels increased from 2.08 (S x 0.28) to a maximal HGH value of 14.22 (S x 0.87) ng/ml. When the stimulatory effect of Nacom was compared with the standard method of arginine infusion in children with normal stature the arginine test was not superior to the Nacom-test. The Nacom-test appears to be a simple and reliable screening method for HGH deficiency, particularly in outpatients.

    Description / Table of Contents: Zusammenfassung Bei Kindern ohne Minderwuchs im Alter von 6–14 Jahren wurde nach oraler Gabe von 250 mg Levodopa und 25 mg l-Carbidopa (Nacom, ein Kombinations-präparat) die Wachstumshormonkonzentration im Serum bestimmt. Alle Probanden zeigten einen ausreichenden Wachstumshormonanstieg. Der Mittelwert betrug 19,6 ng/ml. Nach dem Maximum der HGH-Konzentration ließen sich zwei Gruppen unterscheiden. Die eine Gruppe erreichte zum Zeitpunkt 20 bzw. 40 min, die andere nach 60 bzw. 90 min den stärksten HGH-Anstieg. Aufgrund des Verlaufs der Mittelwertskurve werden 2 Blutentnahmen, 40 und 90 min nach Einnahme des Präparates, zum Ausschluß eines Wachstumshormonmangels für ausreichend gehalten. Das wahrscheinlich zugrundeliegende Wirkungsprinzip der HGH-Sekretion durch l-Dopa und l-Carbidopa wird anhand der Literatur diskutiert.
    Notes: Abstract The stimulatory effect of l-Dopa and l-Carbidopa (Nacom) on HGH secretion was determined in 12 children of normal height aged from 6 to 14 years. Each child received a standard dose of 250 mg l-Dopa and 25 mg l-Carbidopa p.o. HGH concentration in the serum was determined at standard intervals. All subjects showed a sufficient increase of HGH. The mean value was 19.6 ng/ml. According to the maximum values of the HGH concentration the sample can be divided into two groups; the first group reached the highest values after 20–40 min, the second one after 60–90 min. On evaluation of the curve of the mean values it appears that 2 blood samples taken 40 and 90 min after the ingestion of l-Dopa and l-Carbidopa are sufficient in order to exclude HGH deficiency. The theoretical background for HGH secretion after stimulation by l-Dopa and l-Carbidopa is discussed.

    Notes: Abstract Serial TSH and T4 determinations were performed in sixty neonates admitted to our hospital for neonatal intensive care within a period of three months. Seven patients (12%) showed transient hypothyroidism on the basis of low T4 and high TSH values. Only one of these patients, who had meconium aspiration and pneumonia, did not have the respiratory distress syndrome. In addition, 4 of these patients had sepsis. All of the patients were born before 37 gestational weeks and had birth weight under 2200 g. In addition, two patients of this gestational age and birth weight group had a progressive fall of T4 to extremely hypothyroid values without simultaneous elevation of TSH. Two of the 5 patients who died had histological studies of their thyroids. These revealed colloid-depleted vesicles, desquamated epithelium, and prominent vascularisation of the thyroid. The results of this study show that early recognition and therapy of transient hypothyroidism may be live saving.

    Notes: Abstract The activity concentrations of 99mTc-HMPAO in brain after intravenous injection were evaluated in 25 patients using SPECT. With additional first pass studies of heart and brain with the short lived isotope 195mAu, the cardiac output and the mean cerebral transit times of the patients were measured a short time before the HMPAO injection. The time dependence of 99mTc-HMPAO activity in the brain was registered during the first 5 min after injection over both hemispheres. Using a simplified three compartment model it was possible to calculate the mean retention fraction of HMPAO in brain from the time activity curves. It could be shown that the regional cerebral blood flow in ml/min per 100 g can be calculated from the activity concentration of HMPAO in the brain, the cardiac output and the retention fraction. In 15 of the 25 cases the rCBF was measured using the planar 133Xe inhalation method as a reference. We found a significant correlation between the mean hemisphere CBF from our method and the mean hemisphere grey matter CBF from the Xenon method with a correlation coefficient of 0.73.
