    Effect of D-mannose and D-glucose on Escherichia coli bacteriuria in rats (1983)

    Notizen: Summary The effect of D-mannose and D-glucose on bacteriuria due to Escherichia coli with mannose-sensitive adhesins was investigated in adult male Sprague-Dawley rats undergoing diuresis. Inocula of 105, 107, or 108 bacteria in 0.1 ml of normal saline or 2.5% or 10% D-mannose or D-glucose were injected intravesically and urine was cultured 1, 3, 5, 7 and 9 days later. The levels of bacteriuria on days 1 and 5 were significantly lower in rats inoculated with 105 E. coli and 10% D-mannose than in controls (p〈0.05 and 0.01 respectively) and the percentages of rats with 〈 100 bacteria/ml were higher on days 1 and 3 (p=0.05 and 0.02 respectively). Bacteriuria was significantly lower in rats inoculated with 107 bacteria and 10% D-mannose than in controls on days 5 and 7 (p〈0.01 for each day) and the percentage of rats with 〈100 bacteria/ml was higher on day 7 (p=0.01). D-glucose reduced bacteriuria significantly only with a concentration of 10% after instillation of 105 E. coli (p〈0.05, day 1). The results indicate that D-mannose and D-glucose can significantly reduce bacteriuria within 1 day and that their efficacy is dependent upon the concentration of both saccharide and bacteria.

    Ventral bladder hernia facilitates study of urinary tract infections in rats (1981)
    Springer
    Urological research 9 (1981), S. 249-253

    Notizen: Summary Previous studies have demonstrated that after intravesical inoculation of Escherichia coli, rats drinking 5% glucose-water remained bacteriuric for up to 21 days while rats drinking tap water became abacteriuric within a few days. To facilitate accurate monitoring of bacteriuria, we created a ventral bladder hernia for percutaneous aspiration of urine. After intravesical inoculation with 108 E. coli, rats with ventral bladder hernias demonstrated clearance of bacteria at a rate comparable to that observed in rats with intrapelvic bladders (p〈0.01). Of rats drinking tap water, 6 of 7 (85%) with intrapelvic bladders and 8 of 9 (89%) with ventral hernias had less than 10 colony forming units per ml of urine within 9 days of inoculation. Of rats drinking 5% glucose-water, 4 of 5 (80%) with intrapelvic bladders and 6 of 8 (75%) with ventral bladder hernias had 〉105 colony forming units per ml of urine 9 days after inoculation. The results suggest that this technique does not alter the antibacterial response of control or polyuric rats to E. coli inoculated intravesically.

    Notizen: In recent years air quality and atmospheric investigations have become very important topics. This results from a new legal basis for environmental protection which generates the need for the accurate measurement of ambient conditions. Despite the importance of these investigations, detailed reviews characterizing the existing analytical GC systems are scarce. The author has attempted to remedy this unsatisfactory situation by presenting a comprative review of the principal commercially available systems as well as some homemade set-ups. No single method will be optimal for all purposes. The system of choice will depend on the particular application and on the quality and composition of the sample. This review does not attempt to cover all existing systems, but some exotic or lesser known systems have also been included.

    Notizen: Carbon-13NMR data recorded in the pulsed Fourier transform mode are re- ported for 1- and 2-naphthyltrimethyl- stannanes and 9-phenanthryltrimethyl- stannane. Assignments of ring carbon resonances are based on magnitudes of tin-carbon spin-spin coupling constants, substituent chemical shifts, spin-lattice relaxation times and proton coupled spectra.
