    Notes: Abstract Inverse photoemission spectra from Xe(111) crystals grown on an Ag(111) substrate show features which are interpreted in terms of density-of-states emission from the conduction bands of Xe along theГ-L direction. The energies of critical points determined by this method show good agreement with recent spin-polarised photoemission band mapping. A peak which is located in the fundamental band gap is tentatively assigned to surface emission, on the basis of an experiment in which this peak is quenched by covering the Xe crystal with one monolayer of krypton.

    Description / Table of Contents: Zusammenfassung Etwa 80% der 49 untersuchten Patienten mit blander Struma ließen an Hand der normalen Stimulierbarkeit der TSH-Sekretion durch TRH keinen Schilddrüsenhormonmangel erkennen. Die erhöhte Stimulierbarkeit der TSH-Spiegel bei etwa 20% dieser Patienten weist auf einen peripheren, durch Trijodthyronin-Mehrsekretion nicht voll kompensierten Thyroxinmangel hin (präklinische Hypothyreose). Bei den hier untersuchten Struma-Patienten fand sich keine signifikante Korrelation zwischen Thyroxin-Spiegel und Höhe der TSH-Antwort auf die TRH-Belastung. Die normalen TSH-Spiegel bei euthyreoten Struma-Patienten reichen offenbar zur Unterhaltung einer bestehenden Schilddrüsenvergrößerung aus, während sich eine Struma bei erhöhtem TSH-Spiegel vermutlich gerade in einer Wachstumsphase befindet.
    Notes: Summary 30 min after the administration of 200 µg TRH i.v. the increment of the TSH levels over basal levels (Δ TSH 30 min) was studied in 49 patients with nontoxic goiter. Δ TSH 30 min was within the normal range of controls (n=47, mean±2 SD: 2.73–23.60 µU/ml, log. distribution) in the first goiter group of 38 cases (log. mean: 10.40 µU/ml). In the remaining 11 patients with nontoxic goiter, ΔTSH 30 min was significantly (p〈0.0005) elevated (log. mean 32.40 µU/ml) as compared with controls, indicating incomplete compensation of peripheral thyroxine deficiency by disproportionate elevation of triiodothyronine levels (preclinical hypothyroidism).—No significant negative correlation was found between thyroxine levels and TSH response to TRH in the combined groups of the goiter patients studied. Normal TSH levels in patients with nontoxic goiter provide apparently a basis for persistence of the thyroid enlargement, whereas elevated TSH levels may indicate both a period of thyroid hormone deficiency and of thyroid growth.

    Kontrolle der Schilddrüsenhormon-Behandlung der blanden Struma durch Bestimmung der Serum-TSH-Spiegel nach TRH-Belastung (1972)

    Description / Table of Contents: Zusammenfassung Die TRH-Belastung erlaubt, für die Schilddrüsenhormonbehandlung der blanden Struma die individuell verschieden hohe Dosis zu ermitteln, welche das TSH unter die Norm supprimiert und ohne Überdosierungserscheinungen die Struma verkleinert.
    Notes: Summary Consecutive TRH stimulation tests were used in order to determine the thyroid hormone dose which effect-tively suppressed the TSH levels below normal values. This procedure provides a means for individual dosage and helps to avoid thyrotoxicosis factitia in nontoxic goiter patients undergoing thyroid hormone therapy.

    Thyroxine and red cell 2,3-diphosphoglycerate in the newborn period (1973)

    Description / Table of Contents: Zusammenfassung Bei 12 gesunden Neugeborenen wurden die 2,3-Diphosphoglycerat-Konzentration im Erythrocyten und die Thyroxinkonzentration im Plasma während der ersten 2 Lebenswochen bestimmt. Aus den erhobenen Befunden wird geschlossen, daß Thyroxin die 2,3-Diphosphoglyceratsynthese steigert. Damit leitet Thyroxin, über das 2,3-Diphosphoglycerat, die postnatal beschleunigt einsetzende Abnahme der Hämoglobin-O2-Affinität ein, womit eine erleichterte O2-Abgabe an die Gewebe verbunden ist.
    Notes: Summary In 12 healthy newborn infants, red cell 2,3-diphosphoglycerate and plasma thyroxine levels were studied during the first 2 weeks of life. The data obtained indicate that thyroxine increases the 2,3-diphosphoglycerate concentration in the erythrocytes. Thus, thyroxine initiates via 2,3-diphosphoglycerate the accelerated decline of hemoglobin oxygen affinity taking place after birth, which facilates oxygen release from hemoglobin to the tissues.
