Zusammenfassung der Diskussion zum Thema: „Untersuchungsverfahren bei Bewußtlosen“

1979

Zur Beurteilung empfohlener Untersuchungsverfahren mussen zunachst die Anforderungen, die wir an sie stellen, definiert werden. Es mus klar sein, was die einzelnen Untersuchungsverfahren leisten konnen im Hinblick auf die Einschatzung der Bewustseinslage, auf die Ursache der Bewustseinsstorung und Lokalisation eines zerebralen Prozesses und im Hinblick auf die Prognose der Storung. Schlieslich mus klar werden, wie sich das jeweilige Untersuchungsverfahren in den praktischen Behandlungsplan einfugt, insbesondere auch, welche Bedeutung die Verfahren im Hinblick auf notwendige Sofortmasnahmen haben.

Anastomoses (Ileorectal; Colorectal)

1979

With disease processes that involve the large bowel but leave the rectum free (Crohn’s disease, diverticulitis, neoplasms), a surgical procedure used for their treatment will result in an anastomosis that may be seen during rectoscopy. During the postoperative follow-up period, careful attention should be given to any recurrence, which in cases of Crohn’s disease is seen very early on rectoscopy.

Empfehlungen zu Menge und Zusammensetzung der Nahrung

1979

Allen Empfehlungen uber zweckmasige Ernahrung gehen Uberlegungen zum Bedarf an den einzelnen Nahrstoffen und essentiellen Nahrungsfaktoren voraus. Nun ist aber „Bedarf“ ein unklarer Begriff, der meist im Sinne des „Minimalbedarfs“ verwendet wird, also die Menge an einem Stoff angibt, die gerade reicht, um Schaden zu vermeiden. Der Bedarf variiert mit dem Kriterium, das man als Masstab anlegt (z. B. verschiedene klinisch-chemische Parameter, Wachstum, Fortpflanzung, Lebensdauer etc.) und ist nicht konstant, sondern andert sich mit physiologischen oder pathologischen Zustanden. Auch ein „Optimalbedarf“ last sich nicht festlegen, weil der Begriff „optimale Gesundheit“ nicht definiert werden ka…

Regulation of Macromolecular Synthesis during Sea Urchin Development

1979

Immediately following fertilization the sea urchin egg enters a period of very rapid cell division that cleaves the egg cell into about one thousand proportionately smaller cells, which form the swimming blastula, i.e. a larval form that is less vulnerable to environmental injuries since it is capable of actively swimming away from them.

Enzymes as Regulators of Toxic Reactions by Electrophilic Metabolites

1979

Conversion of many compounds which are not electrophilically reactive as such to metabolites responsible for cytotoxic, mutagenic and/or carcinogenic effects is catalyzed by mammalian enzymes. Many reactive agents, whether metabolites or parent compounds, are also subject to inactivation by mammalian enzymes.

Optimization of the phase system in the analysis of polynuclear aromatics (PNA) from diesel engine exhaust by high performance liquid chromatography …

1979

Polynuclear aromatics (PNA) were collected and enriched from diesel engine exhausts by means of a probe and an absorber system. Group separation of PNA from other constituents of exhaust was accomplished through elution with n-heptane on a silica column. A variety of phase systems ranging from unpolar to strong polar packings and eluents, respectively, were tested to resolve PNA into single species. Of these a n-octadecyl bonded silica packing and methanol/water was found to be the most optimal with regard to resolution for real PNA mixtures. Separation was completed within 2–3 h at isocratic conditions.

Kinetics of phenol removal by Nocardia species

1979

Phenol removal by pure cultures of Nocardia corallina was studied in a batch reacting system by estimating both the active biomass and the phenol concentration in the liquid during the experiments. A simple kinetic model was tested and the relative constants determined at 37°C.

STUDIES OF STRUCTURE AND DYNAMICS OF SOLID POLYMERS BY ELASTIC AND INELASTIC NEUTRON SCATTERING

1979

Neutron scattering methods can be applied to solid polymers in order to investigate the structure of the bulk material as well as the nature of the molecular motion. A review of some recently performed studies is presented. Diffusional motion in crystals of chain molecules has been studied by means of quasielastic scattering for the case of n-C33H68 as an example for the relationship between structure and molecular motion. It can be shown that below the so-called rotational transition the paraffin crystals exhibit two types of molecular motion: a translational jump (τt = 0.5 10-8s) and a 180°-rotational jump (τr = 2.5 10-8s). The low frequency vibrations in n-alkanes as models of polyethyle…

Embryo development in Cocos nucifera L.: A critical contribution to a general understanding of palm embryogenesis

1979

InCocos (and probably in all other palms) the embryogenesis shows a number of primitive characters, such as differentiation of the embryo proper from one cell of the pluricellular proembryo, origin of the single cotyledon from a position lateral to the terminal stem tip, and a tendency to cleavage polyembryony.

A high pressure gas target system for the determination of absolute electron scattering cross sections

1979

A high pressure gas target system is described, which is suitable for measurements of absolute electron scattering cross sections and for high resolution electron scattering experiments at medium energies. Details of design and construction are given and special investigations are discussed with respect to straggling effects that take place in the walls and in the gases, and to changes in the gas density, due to heating by the electron beam.

Anitis — Cryptitis — Papillitis

1979

Inflammatory processes within this transitional zone cannot be separated from one another and often occur together. The source of the infection will usually be found in the crypts of Morgagni, originating in the dorsal crypts and spreading to the adjacent papillae. The area of involvement appears erythematous and edematous, and pus occasionally exudes from the crypts. An association exists between cryptitis and the development of anal fissures, and between anal fissures and hemorrhoidal diseases. The anal canal is for the most part also involved in the inflammatory process. One encounters an anitis, which because of an increased secretion produces a perianitis and perpetuates a perianal ecz…

Electrophysiology of the Guinea-pig Pineal Organ: Sympathetic Influence and Different Reactions to Light and Darkness

1979

Publisher Summary Recent electrophysiological studies have shown that the guinea-pig pineal organ comprises two main categories of intrinsic cells, which are (a) pinealocytes which are predominantly influenced by central commissural fibers and (b) pinealocytes which are exclusively influenced by peripheral sympathetic fibers. The first group comprises spontaneously active cells which respond to olfactory, acoustic and short-term optic stimuli respectively. After sympathectomy their spontaneous activity is diminished but not suppressed. The second group comprises spontaneously active cells, which do not respond to short-term sensory stimulation and whose activity depends on the environmental…

A Software Package for a Serum Bank Management

1979

A serum-bank is a collection of human serum samples coming from different locations (in our case Children Hospital, schools, factories, town departemens), allocated in some archives. Principal users of a such data-bank are, of course, physicians and biologists that are mainly interested in statistical analysis (computation of averages, variances factor analysis, etc.) of immunological and epidemiological relevance, in order to investigate about some haematochemical parameters common to some selected subset of the archives [1], [2].

A MODEL FOR VESTIBULAR FUNCTION IN ALTERED GRAVITATIONAL STATES

1979

ABSTRACT During evolution, the vestibular organ was made to serve mainly two purposes: 1) to guide eye movements during sharp turns, so that the point of fixation in the visual field can be kept steady, a function accomplished by the semicircular canal system and 2) to indicate the terrestrial vertical, so that upright posture and gait can be maintained even in the dark. The otolith system serves the latter purpose. Since the function of the semicircular canal system does not depend on gravity, it is not grossly disturbed by gravitational levels different from 1 g . The proper function of the otolith system depends entirely on the presence of a gravitational force vector of 9.8/m/sec2 direc…
