    Notes: [Auszug] Flying insects generate forces that are too large to be accounted for by conventional steady-state aerodynamics. To investigate these mechanisms of force generation, we trained red admiral butterflies, Vanessa atalanta, to fly freely to and from artificial flowers in a wind tunnel, and used ...

    Notes: Penicillins and related β-lactam antibiotics are known to conjugate to proteins to generate potentially antigenic (haptenic) determinants. In the present study, we used a rabbit polyclonal antibody raised against benzylpenicillin (BP) to investigate the capacity of six penicillins and one cephalosporin to generate haptenic groups in vitro on cultured mouse spleen cells and on serum proteins in the culture medium. All of the drugs tested, namely, BP, amoxicillin (AMX), ampicillin (AMP), cephalothin (CEP), cloxacillin (CLX), flucloxacillin (FLX), and phenoxymethylpenicillin (PMP) generated antigens in a concentration-dependent manner on cell and serum proteins, which could be detected by ELISA, although antigens generated by BP, CEP, FLX, or PMP in either cell- or serum-conjugated form were more readily detected than those generated by AMX, AMP, or CLX. Western blot analysis revealed that BP-derived antigens were generated relatively slowly on cell proteins (maximum binding was not yet reached after 8 h), compared to serum proteins (maximum binding within 1 h). BP, CEP, and PMP all generated similar distinctive patterns of immunostaining of electrophoresed cell or serum proteins which did not reflect the relative abundance of different proteins as revealed by Coomassie brilliant blue staining. FLX, CLX, AMP, and AMX did not generate antigens that could be detected on Western blots. In conclusion, we have shown that various β-lactam antibiotics generate antigens on cell and serum proteins that can be detected and characterized immunochemically with polyclonal antiserum. Further application of these methods may offer potential for further identification of immunologically relevant cellular and serum antigens generated by these drugs.

    Notes: [Auszug] The simplest hypothesis to explain these changes is that an increase in foetal pituitary secretion of ACTH stimulates the production of cortisol from the foetal adrenal. The cortisol is thought to act on placental enzyme systems to bring about several changes, in particular an increase in maternal ...

    Description / Table of Contents: Zusammenfassung Die vorliegende Studie befaßt sich mit der pharmakologischen und klinischen Evaluierung von Cephacetril anhand von 23 Patienten mit Infektionskrankheiten des unteren Atemtrakts. Beurteilungskriterien waren, neben pharmakokinetischen Daten wie Serum- und Urinkonzentrationen sowie Serum-Halbwertszeit, sorgfältige bakteriologische und klinische Erhebungen vor, während und nach der Therapie inklusive diverse Laboruntersuchungen, Differentialblutbild, Atemfunktionstest, Sputumbefund, Leber- und Nierenfunktionstests. Bei dem vorwiegend älteren Patientengut (Durchschnittsalter 62 Jahre) mit dominant schwerem Krankheitsbild erbrachte Cephacetril, 2×1 g/die i. m. verabfolgt, in 69 % der Fälle klinische vollen therapeutischen Erfolg, in weiteren 13 % klinischen Teilerfolg. Bakteriologische Heilung und Laborbefunde (z. B. Besserung des Sputum-Befunds) zeigten gute Korrelation zu den klinischen Resultaten. Die Verträglichkeit von Cephacetril war gut, insbesondere besitzt es offensichtlich keine nephrotoxischen Eigenschaften.
    Notes: Summary The study is concerned with the pharmacological and clinical evaluation of cephacetrile as given by the results obtained in 23 patients with lower respiratory infections. The criteria employed comprised not only pharmacokinetic parameters such as serum and urine concentrations and the serum half-life, but also bacteriological and clinical data obtained in the course of careful examinations carried out before, during, and after treatment. The studies conducted for this purpose included various laboratory tests, as well as differential blood counts, tests of respiratory function, sputum investigations, and tests of hepatic and renal function. In the patients under review, most of whom were old (average age 62 years) and in moderate or poor condition, treatment with cephacetrile (1 g twice daily i. m.) enabled a complete clinical success to be achieved in 69 % of cases, a partial success being obtained in a further 13 %. The bacteriological and laboratory findings (e.g. improvement in the sputum characteristics) correlated well with the clinical response. Cephacetrile was well tolerated; in particular, it appeared to have no nephrotoxic properties.

    Notes: Abstract Investigations on springwater acidity were carried out in the Vosges mountains (north-eastern France). Acid or poorly buffered spring and streamwaters were detected in the same area. The proportion of acid springwaters (pH 〈 5.6) is about 20% among 220 springs. The springwater pH on granite are equally spread between 5.0 and 6.8 whereas on sandstone a majority of springs is in the range 5.6 to 6.2. As a whole, but mainly on sandstone, from the 1960's to 1990's, the shape of the pH distributions shifts toward greater acidity. In the sandstone area, trends in pH, alkalinity, total hardness (corresponding to divalent cations), sulfate and nitrate were considered over the 30 yr period (1963-1996) in relation to the bedrock chemical composition. Kendall seasonal tau coefficients indicate that decreasing trends were significant for the first three parameters. Linear regression on the smoothed mean value revealed 18 and 90% decrease for pH and alkalinity respectively, for springwaters draining poor-base cation sandstone whereas only 8 and 30% decrease respectively, was observed on clay-enriched sandstone. On silica-enriched sandstone, alkalinity began to decrease in the early 70's as well as pH. Loss of alkalinity only occurred in the early 80's for springs draining clay enriched sandstone. This can be interpreted as a titration process by acid atmospheric inputs of the buffering capacity of weathering and exchange processes in the soils and the catchment bedrock. The nitrate presents an increasing step in the early seventies but possibly as a result of change in analytical technics and/or increase in atmospheric inputs mainly resulting from increase in fertiliser inputs in agricultural areas or in car traffic. Surprisingly no change in sulfate was noticed in any groups of springs probably as a result of the adsorption/mobilisation in the soils. These long-term trends in spring waters (1963-1996) confirmed the soil and streamwater acidification trends already mentioned in this region, in relation to acid atmospheric inputs since no climate nor forestry practice changes have been detected over the period. Moreover, in spite of acid atmospheric input reductions, no recovery can presently be detected.
