    Description / Table of Contents: Summary Changes of H2O-, Na- und K-Content of the brain in rats and dogs dependent to temperature and time after deep hypothermia up to 0° C and rewarming are beeing described and interpreted as inhibition of active transport of the cations. Thus these changes may serve as an explanation for the abbreviation of survival-time during hypothermia.
    Notes: Zusammenfassung Die Temperatur- und Zeitabhängigkeit der an Ratten und Hunden nach tiefer Hypothermie bis 0° C und Wiedererwärmung zu beobachtenden Veränderungen des H2O-, Na- und K-Gehaltes des Gehirns werden beschrieben. Sie werden als Hemmung des aktiven Kationentransportes gedeutet und geben eine Erklärung für die Verkürzung der Überlebenszeit in Hypothermie.

    Pupillary light reflex and quantitative sensory and motor neural function tests in diabetic patients (1988)
    Springer
    Journal of neurology 235 (1988), S. 245-247

    Notes: Summary In 29 diabetic subjects with or without symptoms of diabetic peripheral and autonomic neuropathy, the association between the pupillary light reflex (the latency of the constriction of the pupil) and various sensory and motor neural measurements, duration of diabetes and quality of glycaemic control was evaluated. Compared with normal subjects the latency of the constriction reaction of the pupil was significantly prolonged in the group of diabetics (mean±SEM: 236.3±5.8 ms versus 210.5±3.7; P〈0.001). Thermal discrimination thresholds were positively correlated with the latency of the constriction reaction of the pupil (r=0.43, P〈0.025). Vibratory perception threshold, motor nerve conduction velocity of the peroneal nerve, H-M interval of the Hoffmann reflex and duration of diabetes were not correlated with the constriction latency, whereas glycaemic control showed a weak correlation. It is concluded that there may be a relationship between autonomic (parasympathetic) pupillary dysfunction and peripheral small nerve fibre dysfunction.

    Untersuchungen über Wasser- und Elektrolytstörungen beim experimentellen traumatischen Hirnödem (1963)

    Notes: Zusammenfassung Beim experimentellen, traumatischen Gehirnödem findet sich ein Absolutzuwachs an Wasser, Na und K im Hirngewebe. Die Konzentration des Astrogliaraums, sowie die Gradienten verändern sich nicht wesentlich. Dies schließt eine grobe Schädigung der Capillarwand und der anschließenden Astrocytenmembran aus. Elektronenmikroskopische Untersuchungen haben diese Annahme bestätigt. Daraus ergibt sich die Forderung, die bisherige Therapie mit hochprozentigen Glucoselösungen beim Hirnödem zu beschränken und andere spezifisch wirksamere Substanzen zu gebrauchen, welche direkt am Transportmechanismus des Na und K eingreifen. Zu diesem Problem soll demnächst an anderer Stelle berichtet werden.

    Differential impedance plethysmography for measuring thoracic impedances (1982)
    Springer
    Medical & biological engineering & computing 20 (1982), S. 187-194

    ISSN: 1741-0444
    Keywords: Differential impedance plethysmography ; Electrical impedance ; Mean specific thoracic impedance ; Thorax

    Notes: Abstract A critical evaluation of the measurement of the transthoracic basic impedance Zo according to Kubicek's method revealed inhomogeneous electrical field-distributions in the region of the neck and the shoulders and in the region of the mammae in female subjects. These inhornogeneties were found to introduce uncontrollable errors, like position dependency into the measurements. Also the sensitivity is deteriorated and the comparability between subjects is lost. A method for measuring thoracic impedances that avoids those disturbances is proposed, and some examples of registrations are presented. The measurements seemed to depend on thoracic fluid content, blood pressure, physiological variations and age. It was concluded that differential impedance plethysmography can be a useful tool in evaluating intra-thoracic processes, both in clinical care and physiological studies. The increased reliability might provide new insight into the determination of cardiac output by impedance cardiography.

    Stimulation and recording of dynamic pupillary reflex: the IRIS technique Part 2 (1988)

    Notes: Abstract The paper describes a newly developed method, called IRIS, for the recording of dynamic pupillary reflexes simultaneously in both eyes. The method is based on the principle of reflection of infra-red light by the iris/pupil boundary. IRIS incorporates a head-fixed. Maxwellian viewing-light stimulator driven by a function generator. IRIS enables pupillary constriction and dilation to be recorded in response to a pulsed light stimulus, thereby permitting determination of the latency times of constriction and dilation. Furthermore, the recording of natural pupil oscillations, the hippus, is possible. IRIS incorporates a clamp-box mode, permitting the study of stimulus-induced pupil oscillations and pupil cycle time. The compact and portable IRIS pupil system combines reliable and accurate recording with general versatility and ease of operation.

    Precise recording of eye movement: the IRIS technique Part 1 (1988)

    Notes: Abstract The paper describes a newly developed method, called IRIS, for the precise measurement of horizontal and vertical eye movements. The method is based on the principle of reflection of infra-red light by the iris/sclera boundary. IRIS combines, when the frequency bandwidth is from DC to 100 Hz, a dynamic measuring range of 30° with a low noise level of 1 min of arc. The installation and application procedure of IRIS, without the need for rigid head fixation, is not complicated and does not require skilled personnel. IRIS allows for simultaneous recordings of the conjugate and disjunctive movements of both eyes, with a linear range up to 25° horizontal and 20° vertical.

    Analysis of recirculation in single-needle haemodialysis (1979)

    Notes: Abstract An analysis of recirculation in single-needle dialysis was performedin vitro. The percentage of recirculation was determined both as a function of fistula flow and of pulsatile arterial outflow, using water and blood as test liquids and using a single-head pump as well as a double-head pump. The most important factors responsible for recirculation were found to be (a) poor fistula flow compared with arterial outflow, (b) dead space and mixing in the needle and y-connectors and (c) compliance of the bloodlines in the dialyser circuit. It is concluded that an efficient, short, single-needle dialysis is not possible for patients with poor fistula flow. For other patients, the percentage of recirculation can be minimised by using a double-head pump and a compliant dialyser.
