    Ultrasonic measurement of residual urine: a method requiring no catheter (1981)

    Notes: Abstract Residual urine was measured with the two-dimensional and the gray-scale equipments (Kretz-Technik) in 26 cases each. The results were checked by catheterization. The difference between the ultrasonographic and the catheter values was 20 to 40 ml for the two-dimensional, but only 5 to 10 ml for the gray-scale apparatus. Ultrasonography is regarded as a reliable and entirely harmless procedure, suited for the measurement of residual urine.

    Description / Table of Contents: Abstract Изучалась взаимосвязь между реакционной способнотью и CH-кислотностью 2-гидрокси-пропиофенонов с целью установления условий конденсации Клейзена. Наидена линейная зависимость между киспотностью метиленовой грушы в α-положении и скоростью синтеза хромона по конденсации Клейзена, катализированной основаниями.
    Notes: Abstract For planning of the conditions of Claisen condensation the relationship between CH-acidity and reactivity of 2-hydroxypropiophenones was investigated. It was found that there is a linear correlation between the acidity of the α-methylene group of these compounds and the rate of base-catalyzed Claisen condensation in the synthesis of chromones.
