    Description / Table of Contents: Zusammenfassung Intraokularer Druck, Blutdruck der A. ophthalmica und Episkleralvendruck stiegen beim Übergang vom Sitzen zum Liegen an, wohingegen der Blutdruck in der A. subclavia unverändert blieb oder geringgradig abfiel. Umgekehrt fielen IOD, Ophthalmica- und Subclaviablutdruck beim Wechsel vom Liegen zum Sitzen. Das Ausmaß des Anstiegs bzw. Falls beim Vergleich von jeweils letztem zu jeweils erstem Meßwert betrug für den IOD ca. 20%, für den Ophthalmicamitteldruck ca. 15% und für den Episkleralvenendruck etwa 50%. Sämtliche Freiwilligen-Gruppen zeigten während der ersten 15min ein Abfallen des Subclaviablutdruckes. Der Ophthalmicamitteldruck fiel bei dem Kollektiv, das zuerst saß, während des Sitzens ebenfalls ab, wohingegen er bei den Freiwilligen, die zuerst lagen, in der ersten Körperposition noch anstieg. Der Episkleralvenendruck stieg nach dem Übergang in die liegende Position stärker als der dazugehörige IOD an.
    Notes: Summary The intraocular pressure, the ophthalmic artery pressure, and the episcleral venous pressure increased after change from sitting to recumbent body position, whereas the subclavian artery pressure remained unchanged or decreased slightly. Changing from recumbent to sitting position was followed by a decrease in IOP, ophthalmic pressure, and subclavian artery pressure. Comparing the last measurement in the first position to the first value after change, it was found that the IOP alters by about 20%, the ophthalmic artery pressure by 15%, and the episcleral venous pressure by 50%. In all series a decrease in subclavian artery pressure was observed during the first 15 min. The mean pressure in the ophthalmic artery diminished in the series that changed from sitting to recumbent position, whereas it increased in the other series during the first 15 min. The episcleral venous pressure increased more than the corresponding IOP after changing to the recumbent position.

    Notes: Summary The ultrastructural localization of acetylcholinesterase (AChE) has been studied in the superior cervical ganglion of the rat. Previous descriptions of the general pattern of localization were confirmed, but in addition, AChE reaction product was found within vesicles in preganglionic nerve terminals, and in pinocytotic vesicles and along the basement lamina of capillaries. There was indication of a continuity between AChE reaction product in the cisternae of the rough endoplasmic reticulum of the principal ganglion cells and extracellular reaction product. These observations are discussed with particular reference to AChE as a secretory protein.

    Description / Table of Contents: Zusammenfassung Ein Testplan für klinische Kontrollmessung neuer Tonometertypen wurde ausgearbeitet, urn den Wert von Neuentwicklungen beurteilen zu können. Für die Berechnung statistischer Werte wird ein Computerprogramm im BASIC-System entwickelt. Als Referenzsystem wird die Applanationstonometrie nach Goldmann benützt. Es werden Vorschläge für Höchstwerte der Abweichungen gemacht.
    Notes: Summary Using the applanation tonometry of Goldmann (mechanical-optical applanation principle with constant diameter of the applanation circle) as a reference system, a test plan inclusive of the necessary conditions for the clinical control measurements of new tonometer types and guiding values for judging the usefulness of these new developments are described. For calculation of the statistical values a computer program in BASIC system is specified.
