    Automatic rezeroing of drifting physiologic signals (1980)
    Springer
    Medical & biological engineering & computing 18 (1980), S. 746-748

    ISSN: 1741-0444

    Topics: Biology , Chemistry and Pharmacology , Medicine
    Notes: Abstract An electronic circuit is described which automatically rezeroes a physiologic signal whenever it reaches the limit of a display. This modified signal can be used for polygraph monitoring while the raw signal is processed by a wide-range high-resolution a.d. convertor. The device is currently used in conjunction with the barometric method for measuring tidal volume, but should find general use in plethysmography.

    Lack of influence of isoproterenol, propranolol, and dopamine on immunoreactive parathyroid hormone and calcitonin in normal man (1983)
    Springer
    Calcified tissue international 35 (1983), S. 32-36

    Notes: Summary Available evidencein vitro andin vivo suggests that pharmacologic doses of isoproterenol stimulate the secretion of parathyroid hormone (PTH) and calcitonin (CT) and propranolol inhibits secretion. However, the findings in man are either quite modest or inconsistent. In view of this controversy, we examined the effects of isoproterenol, 0.15 µg intradermally (i.d.), dopamine, 5 µg/kg body weight over 60 min intravenously (i.v.), and propranolol, 1 mg over 5 min followed by 60 µg per min for 2 i.v. in normal human subjects. It was found that these agents did not alter serum calcium, serum immunoreactive PTH, or plasma immunoreactive CT. The findings do not support a physiologic role for biogenic amines in the control and regulation of PTH or CT secretion in normal man.
