    Thiol content of spruce needles at forest limits (1988)
    Springer
    Oecologia 76 (1988), S. 294-297

    Notes: Summary We determined the water-soluble thiol (SH) content and the osmolality of the cell sap in spruce trees of both low- and high-altitude origin that were transplanted to two test areas at different altitudes (400 m and 1700 m). There was little or no significant difference in SH content and osmotic value between trees of low- or high-altitude origin at the same altitude, but the sulfhydryl (SH) content varied with the altitude of cultivation, being higher at 1700 m than at 400 m. SH content and osmotic value were higher in winter, independent of altitude and provenance. The annual pattern of water-soluble and protein-bound SH content and glutathione reductase activity was measured in spruce trees at 1700 m; these values also peaked in winter and were lowest in summer.

    The effects of various soils, different provenances and air pollution on root tip chromosomes in Norway spruce (1994)
    Springer
    Trees 9 (1994), S. 73-79

    Notes: Abstract The classification of chromosomal aberrations was used to characterize different factors affecting chromosomes in the root meristem of Norway spruce [Picea abies (L.) Karst.] trees. It is important to know the most significant factor affecting the chromosomes in the root meristem of plants at natural sites. The results suggest that an intensive site effect is more significant than the soil or the provenance of the individual. This cytogenetic plant test system was also used to investigate 5-year-old spruce trees exposed in environmental chambers to elevated concentrations of carbon dioxide (750 cm3m−3) and ozone (0.08 cm3m−3) as single variables or in combination, and then transferred to a field for observation of a “memory effect”. The fumigated variants showed an increased number of chromosomal aberrations compared to the controls, which carried on as a memory effect in the root meristems far beyond the fumigation period.

    Effects of glutathione on thiol redox systems, chromosomal aberrations, and the ultrastructure of meristematic root cells ofPicea abies (L.) Karst. (2000)
    Springer
    Protoplasma 212 (2000), S. 227-235 
    Details
    ISSN: 1615-6102
    Keywords: Glutathione ; Root ; Chromosomal aberration ; Ultrastructure ; Picea abies
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary Young spruce seedlings (Picea abies [L.] Karst.) grown in hydroponic culture were exposed to three different concentrations (50,100, and 500 μM) of reduced glutathione for 24 h. These physiologically relevant concentrations of glutathione had a multiple effect on the investigated tissue. Feeding of glutathione to roots increased the concentrations of thiols (glutathione, cysteine, and γ-glutamyl-cysteine) in roots, decreased the rate of cell divisions, induced mitotic abnormalities, and affected the cell ultrastructure. Electron micrographs showed effects such as advanced vacuolation, dilated rough-endoplasmic-reticulum cisternae, and separations of the plasma membrane from the cell wall.

    183. Der verlorene Drain als innere Gallengangsdrainage (1979)

    Description / Table of Contents: Zusammenfassung Bei über 4000 Gallenwegs-Eingriffen wurde bei 35 Kranken der verlorene Drain eingelegt 3mal wegen einer Carcinominfiltration von außen, 27mal wegen eines proximalen Hepaticuscarcinoms und 5mal wegen eines Echinococcus multilocularis. Die postoperative Letalität beträgt 8,5 %. Die Nachuntersuchungen zeigen, daß etwa ein Viertel der Carcinomträger innerhalb von 6 Monaten an der Grundkrankheit verstorben ist, daß aber auch 5 Patienten über die Beseitigung der Abflußbehinderung ihre schwere Carcinomkrankheit bis zu 21/4 Jahre überstanden haben. Bessere Erfolge bringt der verlorene Drain beimEchinococcus alveolaris. Hier wurden mehrjährige beschwerdefreie Intervalle beobachtet.
    Notes: Summary In over 4000 interventions on the biliary tract a sunken drain was inserted in 35 patients: 3 times because of carcinomatous infiltration from outside, 27 times because of a proximal hepatic carcinoma and 5 times because ofEchinococcus multilocularis. The postoperative mortality was 8.5 %. Follow-up examinations show that a little more than a quarter of carcinoma patients died of the primary disease within 6 months but also that 5 patients survived their serious cancer disease for up to 21/4 years after the removal of the drainage obstruction. The sunken drain gives better results in Echinococcus alveolaris. Trouble-free intervals of many years were observed.

    Description / Table of Contents: Zusammenfassung Der Verschluß-Ikterus ist ein Symptom einer ernsten Erkrankung; ihm liegt ein multifaktorielles Geschehen zugrunde. Die für die erfolgreiche Therapie so notwendige Frühdiagnose ist oft nicht möglich, da es meist nur unbestimmte Frühsymptome gibt. Die einzig erfolgversprechende Therapie ist die kurative Operation. Dies bedeutet beim benignen Verschluß die Frühsanierung und beim malignen Verschluß die radikale Tumorentfernung.
    Notes: Summary Obstructive jaundice is a sign of serious disease; it is based on multifactorial events. Early diagnosis, which is of vital importance to successful treatment, is often impossible since in most of the cases there are only nonspecific prodromal symptoms. The only treatment promising success is the curative operation. In benign obstruction this means early sanitation, and in malignant obstruction eradication of the tumor.

    Description / Table of Contents: Zusammenfassung Der maligne Verschluß-Ikterus ist ausnahmslos eine lebensbedrohliche Erkrankung. Bei fehlender Frühsymptomatik ist fast ein Viertel der Kranken primär vollkommen inoperabel, und nur bei einem Fünftel der Tumor resezierbar. Auch bei operablen Fällen sind die Erfolge bescheiden; beim Papillencarcinom lassen sich die höchsten und längsten Überlebenszeiten erreichen. Die wesentliche Chance besteht in der entscheidenden Verbesserung und Verkürzung der präoperativen Diagnostik.
    Notes: Summary Malignant obstructive jaundice is invariably a disease endangering life. Since there are no prodromal symptoms, nearly one-fourth of the patients are primarily inoperable when seen, and in one-fifth is the tumor resectable. Even in operable cases success is moderate; the highest and longest rates of survival can be achieved with papillary carcinoma. A substantial chance lies in the decisive improvement and shortening of preoperative diagnostics.
