The uniform permeability of the capillary bed with general protein impermeability of the small vessel wall, as deduced from the classical interpretation ofStarling's concept, is not generally confirmed by vitalmicroscopic results. Mainly in the mesenteric area the venous end of the...
Out of 27 cases of ventricular and supraventricular parasystole observed in 1969–1970, 7 cases of atrial, 4 cases of A-V junctional and 2 cases of sinus parasystole were presented.
In measuring pulmonary arterial pressure with special catheters in 19 dogs, anesthetized with morphine-urethane, mean pressure differences of 2.2±0.7 (
±sx) mmHg (=9% of lateral pressure) were obtained between lateral pressure and total pressure at normal flow rates, and of 9.1±2.7...
In the isolated, perfused guinea pig heart, the capacity of anoxidative energy liberation was studied. Under aerobic conditions, 0.1 mM dinitrophenol raises the glycolytic rate, which was calculated from oxygen uptake and lactate production, to 25 μmol hexos equivalents/min·g dry weight. In the...
The usefulness of a new indicator-amount principle for quantifying pulmonary regurgitation is demonstrated in an experimental study on 6 pigs which underwent a special procedure to evoke pulmonary insufficiency of variable degree. By use of videodensitometry the changes in the amount of contrast...
Our quantitative morphologic studies of the renal arteries of twenty cases demonstrate that the lumen of one renal artery may show extreme variations of its luminal width, although no branching of vessels occur. In half of the cases the lumen increases distally. Points of narrowed lumen do...
