    Microbial activity and biomass in mixture treatments of soil and biogenic municipal refuse compost (1996)
    Springer
    Biology and fertility of soils 23 (1996), S. 43-49 
    Details
    ISSN: 1432-0789
    Keywords: Nitrogen fractions ; Amino acids ; Amino sugars ; Microbial respiration ; Household waste ; Domestic garbage

    Topics: Biology , Geosciences , Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Abstract An incubation experiment was performed to determine how the mixing of soil with municipal organic refuse compost affects C mineralization, growth of the microbial biomass, and changes in organic components, especially in the fractions of amino acids and amino sugars. Compost and soil differed in almost every parameter measured, with the organic C content of the compost representing only 10.8% of the dry weight. The fractions of K2SO4-extractable organic C and of non-hydrolyzable C were larger in the compost (1.24 and 62.9% of organic C, respectively) than in the soil (0.56 and 41.6% of organic C). These two fractions increased in proportion to the addition of compost, in contrast to amino sugar and amino acid C which were identified overproportionately in the mixture treatments, especially in the 30% compost treatment. Overproportionate increases in the microbial biomass C content and CO2 evolution rate were also measured in this treatment. The adsorption of compost colloids on the surface of regular soil silicates increased both the availability for microbial enzymes and the detectability for chemical analysis.

    Lack of interaction between ramipril and simvastatin (1994)
    Springer
    European journal of clinical pharmacology 47 (1994), S. 373-375 
    Details
    ISSN: 1432-1041
    Keywords: ACE-inhibitors ; Simvastatin ; ramipril ; lipid lowering drugs ; drug interaction ; pharmacokinetics
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Medicine
    Notes: Abstract Twenty two healthy males participated in a randomised, placebo-controlled, double blind, cross-over study to investigate the influence of simvastatin on the pharmacokinetics of ramipril and its active metabolite (ramiprilat), and on the ACE-inhibiting effect of ramiprilat. During two study periods, each of 7 days, subjects received daily either simvastatin 20 mg at 19.00 h or placebo; ramipril (5 mg) was given on Day 5 of each of the periods. Plasma concentrations of ramipril and ramiprilat and ACE-activity were measured in sequential blood specimens, and ramipril and ramiprilat concentrations were measured in urine. Blood and urine collections for pharmacokinetic and pharmacodynamic assessment were made up to 72 h after the dose of ramipril. The mean AUC of ramipril for ramipril+placebo (R+P) and ramipril+simvastatin (R+S) was 22.2 and 21.3 ng.h.ml−, respectively; for ramiprilat the corresponding figures were 61.3 and 57.6 ng.h.ml−. The urinary excretion of ramipril+metabolites for (R+P) and (R+S) was 25.2 and 24.1% of dose. The maximum percentage inhibition of ACE-activity for (R+P) was 94.6%, and for (R+S) it was 94.1%. It is concluded that concomitant administration of simvastatin and ramipril has no clinically relevant effect on the pharmacokinetics or ACE-inhibition of the latter drug and its metabolites.
