Measurement of water distribution and transcapillary solute flux in dog lung by external radioactivity counting.
1. A method for measuring the pulmonary water compartments in vivo in anaesthetized dogs is described. 2. The technique depends upon the sequential intravenous injection of markers labelled with gamma-ray-emitting isotopes. Each is allowed to become evenly distributed throughout the compartment to which it is confined. A calibrated gamma-counter placed at the surface of the inflated lung then r...
متن کاملRenal, transcapillary, net exchange in the dog.
The transcapillary net exchanges of inulin, para-ajiiinohippurate, thiocyanate and heavy water were determined in the renal circulation. It was found that the tracer substances larger than heavy water diffused more freely through renal than through previously studied peripheral or pulmonary capillaries. The results are consistent with the concept of a larger pore size in renal capillaries. P RE...
متن کاملMyocardial transcapillary exchange in the hypertrophied heart of the dog.
Myocardial transcapillary exchange was investigated in control hearts and in two types of hypertrophied hearts: exercise hypertrophy and pathological hypertrophy due to tricuspid insufficiency. Using the single-injection indicator diffusion method (6, 28), myocardial extractions (E), capillary clearances (C), and permeability surface area products (PS) of urea, sucrose, and inulin were measured...
متن کاملTranscapillary exchange in the working left ventricle of the dog.
Sets of multiple indicator dilution curves were obtained from working hearts of dogs with closed chests. A multiple capillary adaptation of a permeabilitylimited capillary model which assumes that exchanging material returns to the capillary at its site of escape was tested on these curves. The model has only two lumped parameters: a permeability surface product per accessible extravascular vol...
متن کاملTranscapillary pulmonary exchange of water in the dog.
T HE CAPILLARIES in the lungs, in contrast to capillaries elsewhere in the body, are in effect bathed in air rather than water. There is little histological evidence for a substantial pulmonary interstitial space; instead, the bulk of the lung tissue appears to consist of cells and blood vessels. Perhaps because of these anatomical peculiarities little or no consideration appears to have been g...
