    Notes: Summary Addition of human placental umbilical cord serum to bone marrow cultures reproducibly increased the number of granulocyte colonies in vitro. This stimulatory effect was significantly greater than that of fetal calf serum which was seen in cultures of human bone marrow under the conditions described.

    Description / Table of Contents: Zusammenfassung. Es wurden 63 Patienten mit einer Oberarmschaftfraktur durchschnittlich 18 Monate nach Unfall sowohl klinisch als auch radiologisch nachuntersucht. 27 Patienten (Gruppe A) wurden operativ und 36 Patienten (Gruppe B) konservativ behandelt. Die Analyse der Ergebnisse nach einem Punktescore nach Kwasny ergab durchschnittlich 6,7 Punkte für Gruppe A und 2,2 Punkte für Gruppe B zu Gunsten des konservativen Vorgehens (p 〈 0,0001; F = 46,9). In den 2 miteinander vergleichbaren Gruppen war die konservative Therapie der chirurgischen Versorgung von Oberarmschaftbrüchen sowohl bzgl. Beweglichkeit von Schulter- und Ellbogengelenk, Kraftminderung, dem Auftreten neurologischer Störungen und von Schmerzen sowie der subjektiven Bewertung der Behandlung und der Kosmetik durch die Patienten überlegen. Die Auswertung der radiologischen Ergebnisse ergab keine Unterschiede (p = 0,48).
    Notes: Summary. Sixty-three patients with humeral shaft fractures were evaluated clinically and radiographically 18 months after injury; 27 patients were treated surgically (group A) and 36 patients conservatively (group B). Analysis of the results according to a score by Kwasny revealed 6.2 points in group A and 2.2 points in group B (P 〈 0.0001; F = 46.9). The results of these two comparable groups suggest that conservative treatment of humeral shaft fractures is superior regarding mobility of the shoulder and elbow, strength, the incidence of neurological complications, pain, subjective rating and cosmesis. There were no differences on roentgenograms between the two groups (P = 0.48).

    Sustained ingestion of methadone and the sleep of monkeys (1978)

    Notes: Abstract Methadone HCl was administered daily to four stump-tailed macaques. The animals' sleep was periodically examined throughout a year of methadone maintenance and, in two animals, during eight months of withdrawal. REM sleep was substantially decreased by methadone treatment and gradually returned to predrug values over a 6-to 8-month period of maintenance. Measures of non-REM sleep and awakenings showed similar disruption with no return to predrug values. These changes were not correlated with alterations in plasma-methadone concentrations. REM sleep rebound occurred temporarily upon drug with-drawal in two animals, but no consistent sleep disruption was apparent during the subsequent eight months. Contrary to some suggestions, therefore, tolerance to the sleep-disruptive effects of the drug may be specific and incomplete, and extended REM rebound upon withdrawal is not a universal response.

    Growth and alkaloid contents in leaves of Tabernaemontana pachysiphon Stapf (Apocynaceae) as influenced by light intensity, water and nutrient supply (1996)

    Notes: Abstract The growth of Tabernaemontana pachysiphon (Apocynaceae) plants and the alkaloid content of leaves were investigated in the greenhouse at three levels of nutrient supply under two contrasting water and light regimes. We determined height increment, above-ground biomass production, leaf size, specific leaf weight and the content of the alkaloids apparicine, A2, isovoacangine, tubotaiwine and tubotaiwine-N-oxide. The effects of major controlling factors such as light, water and nutrient supply could be directly correlated with growth and were largely independent of each other. In contrast, leaf-alkaloid contents were influenced by interdependencies among the main factors and individually affected in a synergistic or antagonistic manner which deviated from the effects on growth. The following general trends could be identified with respect to the quantitatively predominant alkaloids apparicine, tubotaiwine and isovoacangine. Increasing nutrient supply had a positive effect on both growth and alkaloid content. Drought increased alkaloid content, but retarded growth. High light intensity lowered alkaloid content but promoted growth. We investigated the relationship between primary production and the production of secondary metabolites with respect to relative and total alkaloid content as well as in relation to the leaves' nitrogen status. Our results showed that under conditions of low nutrient supply, higher proportions of leaf nitrogen were allocated to alkaloids than at moderate or high nutrient supply. Under conditions of drought and low light, all plants allocated almost equal proportions of leaf nitrogen to alkaloids, regardless of fertiliser. Total alkaloid content per plant, however, increased with fertilisation. With respect to the N-allocation strategy, we found no indication of a trade-off between primary production and the production of secondary metabolites in this species. Rather, our results are in accordance with the carbon nutrient balance hypothesis.

    On the mechanisms of frost injury and frost hardening of spruce chloroplasts (1977)
    Springer
    Planta 137 (1977), S. 195-201

    ISSN: 1432-2048
    Keywords: Chloroplast membranes ; Frost-hardening ; Photochemical activities ; Picea

    Topics: Biology
    Notes: Abstract Hill reaction and noncyclic photophosphorylation of isolated class C chloroplasts of spruce (Picea abies (L.) Karst.), as well as 14CO2 fixation by whole needles at constant laboratory conditions proceeded at high rates during spring and early summer, declined during late summer and autumn by about 60%, remained at this level during winter, and recovered quickly in early spring. During summer, the whole needles proved to be frost labile, since after exposure to-20°C and careful thawing, fast chlorophyll degradation occurred. In addition, only photosynthetically inactive chloroplasts could be isolated from those precooled needles. On the contrary, during winter the photochemical activities of plastids from freshly harvested needles did not differ from those of artificially frozen-thawed needles. When isolated spruce chloroplasts were exposed to the same subfreezing temperatures as the whole needles, no influence of freezing on the photochemical activities was observed, irrespective of whether the plastids were isolated from frost sensitive or frost hardened needles. It is concluded that frost damage to spruce chloroplasts is due to an attack of membrane toxic compounds or lytic enzymes which were liberated upon freezing from more labile compartments. Frost hardening of the chloroplasts, as determined by the stability of chlorophyll after exposure of the needles to low temperatures, as well as by the isolation of photosynthetically active chloroplasts from such precooled needles, appeared to depend at least on 2 processes: (i) an alteration of the composition of the photosynthetically active membranes and (ii) and additional stabilization of these membranes by protecting substances. The first process was indicated by a large increase (decrease) of the capability of isolated chloroplasts for PMS-mediated photophosphorylation which accompanied natural or artificial frost hardening (dehardening). Production of cryoprotecting compounds was suggested by a significant higher stability against NaCl observed with class C chloroplasts isolated from frost hardened needles as compared to that of plastids from frost labile material. The decrease of the capability for both, the ferricyanide dependent photoreactions of the plastids and the CO2 fixation by whole needles, which was observed during the frost hardening phase, cannot be due to freezing injuries; it rather appears to be a consequence of the frost hardening process.

    Formation of C-4 dicarboxylic acids by intact spinach chloroplasts (1975)

    Notes: Summary It is concluded from 14C labelling kinetics as well as from enzyme analysis that formation of malate and aspartate from glycerate-3P via carboxylation of P-enolpyruvate occurs in isolated photosynthesizing spinach (Spinacia oleracea L.) chloroplasts. Carbon incorporation into both dicarboxylic acids was about 1% of the total CO2 fixation. Both acids are suggested to act as substrates for counter exchange for glutamate and α-ketoglutarate.
