    Absorption spectra can be obtained on a wide range of biological samples with little or no sample preparation by using a high sensitivity, low-noise spectrophotometer with the sample in close juxtaposition with the photocathode. An instrument designed for such measurements is described, and possible applications are discussed. The spectrophotometer is a single-beam recording unit using a double-pr... View full abstract»

    The vastly increased capabilities that computers offer the bio-medical research worker are primarily due to the utilization of high-speed digital computers. The techniques of automatic programming are attempts to lighten the load of the programmer and coder, by making the computer itself help prepare the program or code, minimizing the amount of writing a programmer need do. From a functional poin... View full abstract»

    For the transmission of physiological data not requiring complete freedom for the subject, a direct wire system offers many practical advantages including low cost and high reliability. Such a system is particularly well adapted for bedside monitoring and for the usual studies in the clinical laboratory where the patient is required by his illness to be in a fixed position. For general purpose phy... View full abstract»

  • Measurement of Cerebral Blood Flow by External Collimation Following Intravenous Injection of Radioisotope

    Publication Year: 1961, Page(s):173 - 177
    Cited by:  Papers (2)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1316 KB)

    A technique is described which studies cerebral circulation by monitoring with external collimated scintillation detectors the passage through each cerebral hemisphere of a bolus of radioisotope injected intravenously. The test is simple, harmless, almost painless, and repeatable at frequent intervals. Radiation of the patient is minimized by use of a rapidly excreted isotope. Theoretical consider...

    This work has been concerned with the development of a presymptomatic diagnostic tool and with the determination of cardiac function by analysis and interpretation of the vibrations of the heart. The data processing associated with the study includes the use of time-frequency analysis and display equipment, power area measurement circuitry, and also automatic digital interval measurements. With th... View full abstract»

  • EGE Records from Cortical and Deep Brain Structures during Centrifugal and Vibrational Accelerations in Cats and Monkeys

    Electroencephalographic records have been taken from deep regions of the brains of cats and monkeys with chronically implanted electrodes during centrifugal and shaking accelerations comparable to booster forces. Histological and X-ray controls have indicated that displacement of the electrodes does not occur, and that damage to brain tissue is comparable with nonaccelerated animals. A transistori...

  • The Electrocardiogram as an Indicator of Acceleration Stress

    By means of a transistor amplifier mounted before the slip rings of an animal centrifuge it was possible to obtain recordings of the EKG of rats under acceleration stress. With this information, a physiological end point for the tolerance of the rat to 20 G (positive acceleration) was defined as the time to reduce the heart rate of the animal from an initial state ranging from seven to nine beats ...

    Two miniature radio transmitters have been developed for telemetering pressure values from internal body cavities. The large sonde has a volume of 4.1 cc and has a lifetime of up to three months when a mercury battery is used. It is employed for physiological studies on animals, and is attached to the wall of the gastrointestinal canal or other body cavities by sutures at operation. The small sond... View full abstract»
