    Notes: Abstract The interaction between two high-grade polished fused silica plates separated by a thin layer of aqueous LiCl, NaCl and KCl solution, respectively, was determined by means of a selfdeveloped method. Concerning the repulsion created by overlap of the electrical double layers excellent agreement with the DLVO theory down to separation of about 5 nm were found. For still smaller separations a relatively strong additional repulsion arises which according to experimental evidence might be assigned to the overlap of hydration layers emanating chiefly from the alkali metal halide ions adsorbed onto the silica surfaces. Our results agree well with those obtained by Israelachvili et al. and Pashley, who used mica sheets.

    In vivo glucose turnover in hypo- and hyperthyroid starved rat (1980)
    Springer
    Pflügers Archiv 386 (1980), S. 47-52 
    Details
    ISSN: 1432-2013
    Keywords: 3H-(2)-glucose ; 14C-(U)-glucose ; Glucose turnover ; Glucose recycling ; Thyroid state

    Notes: Abstract The effect of hypo- and hyperthyroidism on glucose turnover in vivo was determined in unanesthetized rats starved for 48 h. Glucose pool and decay rate of specific radioactivity of blood glucose was measured after bolus injection of a mixture of3H-(2)- and14C-(U)-glucose under steady state conditions. Compared with euthyroid controls (=100%), hypothyroidism resulted in a decrease of blood glucose concentration (81%), glucose pool (52%), glucose disappearance rate (39%), and total glucose recycling (12%). In contrast, hyperthyroidism led to an increase of blood glucose concentration (148%), glucose pool (121%), glucose disappearance rate (185%), and and total glucose recycling (163%).T 1/2 for glucose was calculated to be 46 min in the hypo-, 34 min in the eu-, and 22 min in the hyperthyroid state. The concentration of circulating glucoregulatory hormones, corticosterone and glucagon were elevated in hyperthyroid rats, while glucagon was diminished in hypothyroid animals. No difference in the level of insulin was found. These data demonstrate that glucose turnover in vivo is a function of the thyroid state being reduced in hypo- and considerably increased in hyperthyroidism.

    Angiotensin Converting Enzyme (ACE) Ein in vitro-Test für die Sarkoidose-Diagnostik (1980)

    Description / Table of Contents: Zusammenfassung Bei 50 Patienten mit Sarkoidose (39 mit aktiver, 11 mit inaktiver Sarkoidose) wurde das Angiotensin-converting enzyme (ACE) im Serum bestimmt. Die Gruppe der Kontrollpatienten umfaßte 50 Personen (34 mit chronischen Lungenerkrankungen, 9 mit Morbus Hodgkin, 7 mit chronischer Polyarthritis). Der Unterschied der Mittelwerte der ACE-Aktivität war zwischen Sarkoidosepatienten (28,6±11,4) und Kontrollpatienten (14,8±4) hochsignifikant (p〈0,001). Ebenso fand sich ein deutlicher Unterschied zwischen Patienten mit aktiver (32,8±11) und inaktiver Sarkoidose (21,9±5,1) mit einemp〈0,001. Corticosteroide senken die ACE-Aktivität bei Sarkoidosepatienten deutlich, ohne daß dies als Hinweis für eine Besserung der Sarkoidose gewertet werden kann. Die gesteigerte ACE-Aktivität bei anderen epitheloidzelligen Granulomatosen (biliäre Zirrhose, Morbus Gaucher, Lepra, Asbestose) repräsentiert möglicherweise einen mit der Sarkoidose gemeinsamen pathophysiologischen Mechanismus.
    Notes: Summary Serum angiotensin-converting enzyme (ACE) was studied in 50 patients with sarcoidosis (39 active, 11 inactive) as well as in 50 control patients (34 with chronic nonspecific lung disease, 9 with Hodgkin and 7 with rheumatoid arthritis). There was a significant difference of ACE activity between sarcoidosis patients (28.6±11.4) and controls (14.8±4), and also between active (32.8±11) and inactive (21.9±5.1) sarcoidosis (p〈0.001). Coricosteroid treatment seems to lower ACE activity in patients with sarcoidosis without offering a clue for clinical improvement. Increased ACE activity in other granulomatous disorders is being discussed. ACE activity thus proves to be a valuable test especially in differentiating active from inactive sarcoidosis.

    A search for internal distortion in CeBi (1980)
    Copenhagen : International Union of Crystallography (IUCr)

    Notes: At the IA magnetic transition (12.5 K) in CeBi a theoretical study has suggested that either the Ce or Bi sublattices should move with respect to the other. Such a distortion would give rise to extra reflections of the form 0′0′l+½. A search for such a reflection using a Bond X-ray diffraction technique was conducted. The 007½ line was not found and an upper limit of 2̃ × 10−4 was set for the magnitude of the expected internal distortion. This limit is valid for a surface layer whose thickness equals the penetration depth of the X-radiation which is about 0.4 × 10−2 mm.

    Small-angle scattering at a pulsed neutron source: comparison with a steady-state reactor (1982)
    Copenhagen : International Union of Crystallography (IUCr)

    Notes: A time-of-flight small-angle diffractometer employing seven tapered collimator elements and a two-dimensional gas proportional counter was successfully utilized to collect small-angle scattering data from a solution sample of the lipid salt cetylpyridinium chloride, C21H38N+.Cl−, at the Argonne National Laboratory prototype pulsed spallation neutron source, ZING-P′. Comparison of the small-angle scattering observed from the same compound at the University of Missouri Research Reactor corroborated the ZING-P′ results. The results are used to compare the neutron flux available from the ZING-P′ source relative to the well characterized University of Missouri source. Calculations based on experimentally determined parameters indicated the time-averaged rate of detected neutrons at the ZING-P′ pulsed spallation source to have been at least 33% higher than the steady-state count rate from the same sample. Differences between time-of-flight techniques and conventional steady-state techniques are discussed.
