    Description / Table of Contents: Zusammenfassung Bei spontaner physiologischer, pathologischer oder forcierter Hyperventilation sinkt mit fallendem arteriellem PCO2 die Hirndurchblutungsgröße ab. Parallel verläuft eine zeitlich nicht verzögerte kompensatorische Zunahme der O2-AV-Differenzen. Mit Hilfe fortlaufender enzymatischer Bestimmungen und Registrierungen der arterio-hirnvenösen Glucosegehalte konnten wir nun erstmalig zeigen, daß auch der hirnvenöse Glucosegehalt zeitlich unverzögert kompensatorisch absinkt. Dies ist ein Hinweis darauf, daß die Hirnzellen pro Blutvolumeneinheit bei verminderter Zirkulationsgröße vermehrt Glucose ausschöpfen. Es kann somit bei nicht kritischer Durchblutungsverminderung ein ungestörter Glucosestoffwechsel stattfinden. Bei Abfall des arteriellen PCO2 unter 25 mmHg muß jedoch, besonders bei vorgeschädigtem Gehirn, mit ungünstigen Auswirkungen auf den Hirnstoffwechsel gerechnet werden: Die Hirndurchblutungsgröße sinkt unter eine kritische Schwelle, bei der eine ungestörte Sauerstoffaufnahme nicht mehr gewährleistet ist. Daneben erschwert die respiratorische Alkalose über den Bohr-Effekt die Sauerstoffabgabe vom Haemoglobinmolekül an die Ganglienzellen. Die Folge dieser beiden Störfaktoren ist die Abnahme der energieliefernden oxydativen Glykolyse und stattdessen die Zunahme der wenig energieliefernden anaeroben Glykolyse mit Vermehrung der Laktatbildung und schädigenden Gewebs- und Liquoracidose. Die Untersuchungen zeigen, daß eine therapeutische Hyperventilation nicht ratsam ist, und daß krankhafte zentrale Hyperventilationen eine weitere Gefahrenquelle darstellen.
    Notes: Summary CBF decreases when arterial PCO2 is lowered by physiological, pathological or therapeutically induced hyperventilation. This is accompanied by an undelayed compensatory increase of oxygen-av-differences. Continuous monitoring of enzymatically determined glucose-av-differences of the brain during hyperventilation has for the first time shown that there is an undelayed fall of the cerebral venous glucose content, too. This indicates that the brain cells extract an augmented amount of glucose per ml blood during decreased CBF. Therefore glucose metabolism of the brain is not impaired during non-critical CBF reduction. However, when arterial PCO2 falls below 25 mmHg a detrimental effect on CBF and cerebral metabolism has to be expected. CBF will then decrease below the critical threshold for an undisturbed oxygen supply, and the respiratory alcalosis will lead to a disturbed oxygen delivery due to the Bohreffect. As a consequence both of these factors will reduce the energy-yielding oxydative glycolysis and augment the little energy producing anaerobic glycolysis with a concomitant increase of lactate formation, resulting in a tissue and spinal fluid lactate acidosis. From our results it is therefore concluded that induced hyperventilation should be avoided, and that central hyperventilation in diseased states has to be considered as an additional threat to the brain.

    A theorem on maximum variance (1978)

    Notes: Abstract The square variance function of a finite-dimensional Hamiltonian H obeys a maximum principle that leads to the determination of its maximum and minimum eigenvalues. A systematic algorithm is presented that generates a sequence of monotonically increasing values for the square variance. It is shown that the method converges to the exact two-dimensional eigenvalue problem determined by the lowest and highest eigenvalues. Preliminary numerical results are briefly outlined.

    Röntgenographische und spektroskopische Untersuchungen an PtII-PtIV-Doppelverbindungen vom Typ des WOLFFRAMSchen Salzes (1976)

    Description / Table of Contents: X-Ray Diffraction and Spectroscopic Studies on PtII-PtIV Compounds Derived from WOLFFRAM'S SaltX-ray diffraction single crystal and powder data of [Pt(C2H5NH2)4][PtBr2(C2H5NH2)4 Br4 · 4H2O yield a tetragonal unit cell with dimensions a = 13.427(9) Å and c = 5.606(5) Å. The compound is isomorphous with WOLFFRAM'S salt, Pt(C2H5NH2)4][PtCl2(C2H5NH2)4]Cl4 · 4H2O. A structure of chains running parallel c is proposed along which square planar Pt(C2H5NH2)42+- and octahedral PtBr2(C2H5NH2)42+-groups alternate. Bromine acts as bridging ligand between PtII and PtII. Anhydrous [Pt(C2H5NH2)4][PtJ2(C2H5NH2)4]J4, prepared for the first time, forms tetragonal crystals with a = 12.173(4) Å and c = 12.732(6) Å. X-ray diffraction data show this compound to be isomorphons with the anhydrous bromo compound and to have an analogous chain structure. Reflectance spectra in the visible range and far infrared spectra confirm the proposed structures.
    Notes: Einkristall- und Pulver-Röntgenaufnahmen von [Pt(C2H5NH2)4] [PtBr2(C2H5NH2)4]Br4 · 4H2O ergeben eine tetragonale Elementarzelle mit den Dimensionen a = 13,427(9) Å und c = 5,606(5) Å. Für die Verbindung, die isomorph mit WOLFFRAMS Salz, [Pt(C2H5NH2)4][PtCl2(C2H5NH2)4]Cl4 · 4H2O, ist, wird eine entlang c verlaufende Kettenstruktur postuliert. in der planare Pt(C2H5NH2)42+-Einheiten und trans-PtBr2(C2H5NH2)42+-Oktaeder abwechseln. Die Verknüpfung von PtII und PtIV erfolgt dabei über Br als Brückenligand. Die erstmals dargestellte wasserfreie Jodoverbindung, [Pt(C2H5NH2)4][PtJ2(C2H5NH2)]J4, gehört zum tetragonalen Kristallsystem mit a = 12,173(4) Å und c = 12,732(6) Å. Ein Vergleich der Röntgendaten mit denjenigen der isomorphen wasserfreien Bromoverbindung legt nahe, daß auch die Jodoverbindung eine analoge Kettenstruktur in c-Richtung bildet. Remissionsspektren im sichtbaren Bereich und Infrarotspektren bestätigen die gemachten Strukturvorschläge.
