Presence And Absence

The present study was designed to assess the effects of increased vocal level on stuttering in the presence and absence of noise, and to assess the effects of noise on stuttering with and without a concomitant increase in vocal level. Accordingly, eight adult stutterers spoke in quiet with normal vocal level, in quiet with increased vocal level, in noise with normal level, and in noise with increased level. All subjects reduced stuttering in noise compared with quiet conditions. However, there was no difference in stuttering when subjects spoke with normal compared with increased vocal level. In the present study, reductions in stuttering under noise could not be explained by increases in vocal level. It appears, instead, that reductions in stuttering were related to a decrease in auditory feedback. The condition which resulted in the largest decrease in auditory feedback, speaking in noise with a normal level, also resulted in the largest decrease in stuttering.

ZusammenfassungNach tierexperimentellen Voruntersuchungen wurde die Placentographie mit trägerfreiem 113Inm -HSA als klinische Methode eingeführt. Vor Amniocentesen und bei Verdacht auf Placenta praevia werden Placentographien geschrieben. Den Schwangeren wird eine Aktivität von 500 μCi in die Cubitalvene injiziert. Die der Aktivität entsprechende Indiummenge ist kleiner als 0,1 ng. Die fetale Strahlenbelastung liegt unter lOmrad. Bei Anwendung von 113Inm-HSA entfällt eine Blockade der mütterlichen und fetalen Schilddrüsen. Die genaue Abgrenzung einer Placenta praevia wird nicht durch eine Blasenaktivität beeinträchtigt.Es wurden bisher 19 Placentalokalisationen durchgeführt. In allen Fällen konnte der Placentasitz eindeutig festgestellt werden. Bedingt durch die lange Liegezeit beim Aufnehmen eines Szintigramms kam es in zwei Fällen zu einem Vena-Cava-Kompressions-Syndrom. Zur Verhinderung dieser klinischen Zwischenfälle werden inzwischen Placentographien mit der Anger-Kamera aufgenommen. Mit Hilfe des divergierenden Kollimators konnte der gesamte Abdominalbereich erfaßt werden. Die Aufnahmezeit konnte auf 7 — 10 Minuten verkürzt werden. Die intravenöse injizierte Aktivität betrug bei dieser Methode ebenfalls 500 μCi. Der diagnostische Aussagewert der Kamerabilder ist szintigraphischen Aufnahmen gleichwertig.

This study demonstrates that in spite of measured normal concentrations of carrier proteins one cannot deduce in all cases a normal fT3 from a normal level of TT3 when 1-thyroxine given for diagnostic or therapeutic purposes is present in excess. The displacement of 1-triiodothyronine from its binding sites is shown in 35 patients with non-toxic goitre who received an oral dose of 200 μg 1-thyroxine/die for two weeks. Apart from a significant increase of TT4 (from 7.85 to 14.21 μg/dl ≙ + 81 %) and of fT4 (from 1.58 to 3.7 ng/dl ≙ + 134%) there is only a slight increase in TT3 from 148 to 158 ng/dl (≙ + 10%) after 14 days of treatment. By contrast fT3 rises clearly from 4.97 to 8.07 pg/ml ≙ + 63% (normal range: 2.8-5.6 pg/ml). Compared with the increase of TT3 (+ 10%) the free T3 rises by a factor of 6.3 (63 %/10%). On account of higher affinity of 1-thyroxine to binding proteins the free T4 is influenced to a lesser degree. Compared with the increase of TT4 (+ 81 %) free T4 rises by a factor of 1.6 (134%/81 %). It is supposed that the serum concentration of free T3 can be increased despite a normal concentration of TT3 when 1-thyroxine is present in excess. Therefore, for laboratory work fT3 should be assigned a higher validity than TT3 when patients are treated with comparatively high doses of 1-thyroxine.

SummaryA procedure is described for partial purification of an inhibitor of the activation of plasminogen by urokinase and streptokinase. The method involves specific adsorption of contammants, ion-exchange chromatography on DEAE-Sephadex, gel filtration on Sephadex G-200 and preparative electrophoresis. The inhibitor fraction contained no antiplasmin, no plasminogen, no α1-antitrypsin, no antithrombin-III and was shown not to be α2 M or inter-α-inhibitor. It contained traces of prothrombin and cerulo-plasmin. An antiserum against the inhibitor fraction capable of neutralising the inhibitor in serum was raised in rabbits.
