The net transvascular filtration rate, JF (ml/min/100 g), in an isolated, RBC-free perfused R3230AC mammary adenocarcinoma tumor was measured using a gravimetric method whereby changes in tissue weight over time were monitored. From the gravimetric measurements of JF following changes in venous pressure, the capillary filtration coefficient (ml/min/mm Hg/100 g) was found to be 2.2 (range, 0.8 that capillary filtration and hence lymph flow are actually increased in this condition. According to the Landis-Pappenheimer formulation, in the steady state net capillary filtrate or lymph load (F) = lymph flow (LF) or where C=capillary filtration coefficient, Pc=blood capillary pressure, Pj=pericapillary Their capillary filtration coefficient was measured in the upper arm using a volumetric technique at rest and during lower body negative pressure (LBNP). We calculated the driving force for transcapillary fluid transfer.RESULTS: The increase in heart rate and the decrease in systolic blood pressure during lower body negative pressure were similar in diabetic and control subjects. 2021-03-19 · Cutaneous blood flow increased by almost 170% and the capillary filtration coefficient by about 40%, whereas the clearance did not change.

Determinants of GFR. GFR = Capillary filtration coefficient X Net filtration pressure. Increased glomerular Capillary filtration coefficient increases GFR. Probably

Renal vasodilation of afferent arterioles and increased renin release occur via macula densa feedback due to reduced NaCl delivery to the macula densa. The reflection coefficient is high: about 1.0 (i.e. the filtrate is a true ultrafiltrate as the glomerular capillaries are essentially impermeable to protein (so oncotic pressure in the filtrate is zero) The hydrostatic pressure in the capillaries is high and does not decrease much along the length of the capillary The net filtration pressure (NFP) represents the interaction of the hydrostatic and osmotic pressures, driving fluid out of the capillary.

Traditionally, the reflection coefficient of proteins across the capillary wall is assumed to be approximately one. Capillary permeability was analyzed in both normal rat brain and intracerebral 9L gliosarcoma tumor and in rhesus monkey brain using a newly derived formula for the capillary permeability coefficient (P).The Pvalue for isotopic urea and sodium was less in monkey brain than in rat brain. The net transvascular filtration rate, JF (ml/min/100 g), in an isolated, RBC-free perfused R3230AC mammary adenocarcinoma tumor was measured using a gravimetric method whereby changes in tissue weight over time were monitored.

Capillary filtration coefficient (CFC), vascular resistance (R), and perfusate O2 content were measured in each period. The arterial O2 content fell from fully equilibrated to 0.25 vol% during the use of N2. R fell from about 6 mmHg X min X 100 g X ml-1 during O2 bubbling to approximately 1.0 with N2. The capillary filtration coefficient was measured in human extremities by a simplified technique using the capacitance plethysmograph. The method was validated in terms of consistency of values obtained on the same individual at various times, the correspondence between values obtained on a group of normal persons, and the agreement between values reported here and those of earlier workers The capillary filtration coefficient (CFC) is assumed to reflect both microvascular hydraulic conductivity and the number of perfused capillaries at a given moment (precapillary sphincter activity) This is called the whole body capillary filtration coefficient. The filtration coefficient can also be expressed for separate parts of the body in terms of rate of filtration per minute per millimeter of mercury per 100 grams of tissue. On this basis, the filtration coefficient of the average tissue is about 0.01 ml/min/mm Hg/100 g of tissue.

The capillary filtration coefficient of the cat small intestine was measured in four ways; the conventional measurement was compared with the “zero time extrapolation” technique, and with two methods designed to assess the end of the blood volume shift due to venous pressure elevation. 2020-07-10 reflection coefficient ofthe capillary would be given by-K,ACRT'vd0 (2) where C-d is the test solute osmotic reflection coefficient, Jv O is the initial rate of weightloss, ACis thechangeinconcentration oftestsoluteintheperfusate,Kfis the capillary filtration coefficient, R is the gas constant and T is the absolute temperature. 16 Capillary filtration coefficients (KI,~) were determined in the isovolumetric loop by suddenly increasing venous pressure and observing the volume changes of intes- tine. The volume change after venous pressure elevation is characterized by two distinct components: an initial rapid Capillary filtration coefficient, vascular resistance, and compliance in isolated mouse lungs.
