[A new method for determining capillary filtration coefficients in tissues. 1. Methodologic principles].
A new method for measurement of the capillary filtration coefficient (CFC) is developed which avoids the errors of the known method of Pappenheimer and Soto-Rivera. The principle of our method consists in installation of the prepared tissue into a plethysmograph where it becomes exposed to a one step-pressure increase by which the tissue is pressed out. The CFC measurement is carried out by continuous weighing of the blood as it flows out of the arterial and venous parts of the prepared tissue vessels. The basic theoretical conception of this method is proven by means of tissue model.
