    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).

    Notes: Abstract. Photosynthetic CO2 uptake, the photochemical efficiency of photosystem II, the contents of chlorophyll and chlorophyll-binding proteins, and the degree of frost hardiness were determined in three-year-old Scots pine (Pinus sylvestris L.) trees growing in the open air but under controlled daylength. The following conditions were compared: 9-h light period (short day), 16-h light period (long day), and natural daylength. Irrespective of induction by short-day photoperiods or by subfreezing temperatures, frost hardening of the trees was accompanied by a long-lasting pronounced decrease in the photosynthetic rates of one-year-old needles. Under moderate winter conditions, trees adapted to a long-day photoperiod, assimilated CO2 with higher rates than the short-day-treated trees. In the absence of strong frost, photochemical efficiency was lower under short-day conditions than under a long-day photoperiod. Under the impact of strong frost, photochemical efficiency was strongly inhibited in both sets of plants. The reduction in photosynthetic performance during winter was accompanied by a pronounced decrease in the content of chlorophyll and of several chlorophyll-binding proteins [light-harvesting complex (LHC)IIb, LHC Ib, and a chlorophyll-binding protein with MW 43 kDa (CP 43)]. This observed seasonal decrease in photosynthetic pigments and in pigment-binding proteins was irrespective of the degree of frost hardiness and was apparantly under the control of the length of the daily photoperiod. Under a constant 9-h daily photoperiod the chlorophyll content of the needles was considerably lower than under long-day conditions. Transfer of the trees from short-day to long-day conditions resulted in a significantly increased chlorophyll content, whereas the chlorophyll content decreased when trees were transferred from a long-day to a short-day photoperiod. The observed changes in photosynthetic pigments and pigment-binding proteins in Scots pine needles are interpreted as a reduction in the number of photosynthetic units induced by shortening of the daily light period during autumn. This results in a reduction in the absorbing capacity during the frost-hardened state.
