    Description / Table of Contents: Zusammenfassung Es wird ein Patient beschrieben, bei welchem zwei seltene Typen von abnormen Augenbewegungen vorhanden waren: zunächst typisches “ocular bobbing” und anschließend intermittierende vertikale Oszillationen der Augen. Es wurde eine Serie von elektrooculographischen Registrierungen dieser Augenbewegungen analysiert. Aus der Beobachtung wird gefolgert, daß diese beiden Typen von vertikalen Augenbewegungen eine gemeinsame pathophysiologische Grundlage haben könnten. Es wird angenommen, daß die Funktion von verbleibenden oculomotorischen Bahnen beim Zustandekommen dieser Augenbewegungen eine wichtige Rolle spielen könnte.
    Notes: Summary A surviving patient with two rare types of abnormal eye movements, typical ocular bobbing and subsequently developed intermittent vertical oscillations of the eyes, is described, and a follow-up series of electro-oculographic recordings of these eye movements is analyzed. It is suggested that these two types of vertical eye movements might have a common pathophysiological background and the activity of remaining functional oculomotor pathways may play an important role in their occurrence.

    Notes: Micro capillary columns were successfully applied to liquid chromatography by employing the principles used in micro high performance liquid chromatography. Fundamental investigations on the use of capillary columns in LC were performed for the various column parameters. Good separations of five aromatic hydrocarbons and four kinds of phthalic esters were obtained on a 62 μm I.D. capillary column, coated with SE-30.

    Notes: Capillary columns in gas chromatography, first proposed by Golay [1,2], have become well established [3] which have extremely high column efficiencies and separabilities. Everyone could imagine it to be a great tool if such a kind of high efficiency column could be established in liquid chromatography (LC). Microcapillary liquid chromatography (MCLC) may be one way of achieving high-efficiency in terms of theoretical plates. Few papers were published in this field before 1976 [4-6], but more recently, after 1977 [7-15], this field has become one of topical interest in liquid chromatography. Temporarily there are two microcapillary liquid chromatography, that is: „open-tubular“ [7,8,10-15] and „packed“ [9] MCLC. In this presentation we focus on open-tubular microcapillary liquid chromatography and a review contemporary developments of ours and others.
