The course of dosed insufficiency of the mitral valve in animals under lowland conditions is characterized by marked compensatory capacity of the organism. Under the effect of high-altitude hypoxia (3,200 m), the disease of the mitral valve is attended with overloading of the left atrium with the
Dose-response curves with ouabain, theophylline and 2-[(2-methoxy-4- methylsulfinyl)phenyl] -1H-imidazo[4,5-b]pyridine (AR-L 115 BS) were obtained from electrically driven isolated left guinea pig atria (at 35 degrees C and 3 Hz, 0.5 ms and 0.4--0.6 mA 10% above threshold) measuring the auxotonic
With regard to a paper of Leydhecker the basic principles of a combined treatment of ocular and cerebral vascular disturbances with Strophanthin, resp. Digitalis, Vasodilatators, and Hydrocortisone medicaments are again discussed. The influence of hypoxia in vasodilatation, the confirmation of
The concentration of thallium-201 in the myocardium immediately following injection of tracer is the result of both blood flow delivering tracer to the heart and extraction by the myocardium. In these studies, the extraction of thallium-201 by the canine myocardium was determined as a function of
Contractile activity of electrically driven left atria of guinea pigs was measured auxotonically under normoxic and anoxic conditions at various frequencies and temperatures in Krebs-Henseleit solution containing 15 mM glucose. At 35 degrees C, a frequency of 0.5 Hz and anoxia ("anoxia test")
To compare efficacy of conventional therapy, antihypoxants olifen and amthizol (groups 1, 2 and 3, respectively) 49 patients with congestive heart failure stage IIb according to the Vasilenko-Strazhesko classification were treated. In hospital the pre-hospital scheme of treatment was not changed
