Untersuchungen iiber Eigenschaftcn und Verwendungsmogliclikeiten eines flexiblen Extremitatcnplet.hysmografen. tlcta physiol. scand. 1959. 46. 1--18. -The flexible extremity plethysmographs described by ~O H N were invehgated on a dummy and in situ and found especially suitable for blood flow measurements by means of occlusion plethysmography. The niodels for forearm and calf could be used also on moving subjects, e. y. performing physical work. The plethysniographs consist of thin air-filled rubber cuffs. Volume changes of the extremity caused proportional changes of the filling pressure of the plethysmographs, which at rest was 40 mm H,O and during venous occlusion increased by less than 10 mm H,O. The pressure changes were continuously recorded on a ca.pacitance manometer. Some properties and applications of the plethysmographs are described. Quantitative Durchhlutungsmessungen a n menschlichen Extreinitaten sind his heute in verlasslicher Form iiur m i t der Venenverschlussplethysmografie moglich. Bei der arbeit,enden Versuchsperson wird ihre Anwendung jedoch schwierig. Die bekannten 1 -59.7285. Arta p h y s i o l . scund. Vol. 46.
The effects of intravenous administration of angiotensin on the arterial pressure and on the renal, carotid, iliac, uterine, and femoral blood flows were investigated in dogs and sheep through the use of implanted electromagnetic flowmeters. The rise in arterial pressure was immediate and, within the range of doses employed, presented little relation ship to the dose. The pressor effect of angiotensin was accompanied by a consistent fall in the renal blood flow and a rise in the femoral, iliac, and uterine flows. Carotid flow was less affected. These studies demonstrate the specificity of flow response to a given change in pressure in the various areas of the body.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
