    Notes: Summary In a clinical study we tested the following parameters: free fatty acids, beta-hydroxybutyrate, acid-base-balance, lactate, bilirubin, uric-acid, fructose, xylitole, glucose in blood and urine. The tests were executed in 9 patients who were undergoing stomac operations. The cardio pulmonary system of all patients was normal, and there was a homeostasis in water and electrolytes preoperatively. In combination with the amino-acids we received a ratio of 1/3n1/3n1 for glucose, levulose and xylitole. Totally, the patients received 0,36 g per kg body weight and per hour of carbohydrates. Beta-hydroxybutyrate, aceto-acetat, and free fatty acids show normal values under conditions of parenteral nutrition as well as lactate, uric acid, and acid-base-balance. The ratio of the different carbohydrates in serum and urine prove that the infusion time and volume were extremely favourable. The loss of carbohydrates in urine was very low.

    Notes: Abstract There is an empirical function of the heights of tides on the Sun produced by Venus, Earth, and Jupiter whose period is nearly equal to that of the 11-yr sunspot cycle (Wood, 1972). This period match has been used in suggestions that planetary tides cause sunspots and, indirectly, terrestrial climate changes and earthquakes. We derive the period of the tidal function in terms of the planetary orbital periods and show that it is artificially lengthened by aliasing. Furthermore, there exists a class of functions whose measure in frequency space is so great that, in the absence of a physical justification for preferring one member, no statistically significant period match can possibly be made with current sunspot data.

    Notes: Summary Various brands of digoxin tablets, and even different batches of one brand, may differ greatly in bioavailability. Digoxin-Sandoz® tablets have been compared with Lanoxin® manufactured between 1969 and 1972 and after May 1972. Comparisons were also made between and within batches of Digoxin-Sandoz tablets. Three separate cross-over studies were conducted involving a total of 20 volunteers. Digoxin-Sandoz tablets were shown to have a constant bioavailability and to produce plasma concentrations very similar to “new” Lanoxin. Storage for 2 years of one batch of Digoxin-Sandoz did not alter the bioavailability. Particle size was shown to influence bioavailability. Care should be exercised when plasma data alone are interpreted as an index of bioavailability. Measures of bioavailability based on plasma data obtained up to 6 h after administration differed from those based on cumulative urinary excretion data (in this study by a factor of about 2), which can lead to the belief that a difference in bioavailability is much greater than is actually the case. Data from cumulative urinary excretion, collected over a sufficiently long period of time, are likely to be the most reliable method for determining the bioavailability of a substance such as digoxin.

    Notes: A method is described for the micro-identification of both mono- and diesters of 12-deoxyphorbol based upon a combination of thin-layer chromatography and mass spectrometry. The technique may be used on as little as 5 ml of fresh plant latex. Nine thin-layer systems are described, six of which are adsorption systems based on silica gel or alumina as adsorbent, and three are partition systems using diethyleneglycol as stationary phase. The migration by means of thin-layer chromatography is dependent upon the chain length of the C-13 esterifying acid and on the presence or absence of a free primary hydroxyl group at C-20. By means of mass spectrometry it was possible to confirm the identity of the esterifying moiety at both the C-13 and C-20 positions of 12-deoxy-4βOH-phorbol.

    Description / Table of Contents: The mass spectrometric fragmentation products of the four isomeric monophenyl amino oxadiazoles, 2-amino-5-phenyl-l, 3,4-oxadiazole, 3-amino-5-phenyl-l, 2, 4-oxadiazole, 5-amino-3 phenyl-l, 2, 4-oxadiazole and 3-amino-4-phenyl-1, 2,5-oxadiazole, differ with respect to their fragment composition and abundance in such a way that isomers can easily be distinguished and determined. The most important fragmentation patterns giving characteristic ions for structure identification are discussed.
    Notes: Die massenspektrometrischen Zerfallsprodukte der vier isomeren phenyl-substituierten Amino-oxadiazole, 2-Amino-5-phenyl-l.3.4-oxadiazol, 3-Amino-5-phenyl-l.2.4-oxadiazol, 5-Amino-3-phenyl-l.2.4-oxadiazol und 3-Amino-4-phenyl-l.2.5.oxadiazol, unterscheiden sich sowohl hinsichtlich der Art der Fragmentzusamrnensetzung als auch der Signalintensitäten so charakteristisch, daß eine eindeutige Differenzierung von Ring- und Stellungsisomeren moglich ist. Die wichtgsten Fragmentierungswege, die zu den strukturspezifischen Ionen führen, werden diskutiert.
