    Pharmakokinetik und Pharmakodynamik von Theophyllin bei multimorbiden geriatrischen Patienten (1987)

    Journal of molecular medicine 65 (1987), S. 551-557

    Notes: Summary The pharmacokinetics of theophylline (200 mg i.v.) were determined in 20 geriatric patients with multiple diseases. Serum concentrations were fitted to an open 2-compartment model. Percent changes in venous pCO2 and pO2 were used as parameters of the pharmacodynamic action. Total clearance was decreased and elimination half-life of theophylline was found to be prolonged in the elderly patients compared with data of a study with young healthy volunteers. The stronger the pharmacodynamic action of theophylline (percent change of venous pCO2 after 30 min), the faster was its elimination and the lower were measured concentrations after 2, 6, and 12 h.

    Effects of N-immissions on nutrient status and vitality ofPinus sylvestris near a hen-house (1989)
    Springer
    Plant and soil 113 (1989), S. 279-282 
    Details
    ISSN: 1573-5036
    Keywords: forest decline ; nitrogen immission ; nutrient status ; Pinus sylvestris

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Abstract Near a hen house (50–600 m), vitality ofPinus sylvestris, N-, P-, K-, Ca-, Mg-contents of the needles, N-, Mg-, K-, Ca- and Al-contents in soil extracts and NH3/NH 4 + -contents of the air were determined. Damage symptoms occurred when N-immissions hit the canopy directly. In contrast no visible decline of the above ground plant could be observed if N was mainly deposited on the soil.
