Dextrans and Glycogens as Particulate Tracers for Studying Capillary Permeability
Commercially available glycogens and dextrans can be used as biological particulate tracers in work on capillary permeability. These polysaccharides are well tolerated in intravenous injection and induce no vascular leakage when applied topically (cremaster test) in mice and in Wistar-Furth rats. The particles stain adequately with lead after aldehyde-OsO(4) fixation in phosphate buffer and pro...
متن کاملCapillary Permeability to Plasma Proteins.
ACCORDING to the classical hypothesis of Starling (1896) the exchange of water and small lipid-insoluble molecules across the capillary membrane is largely governed by the balance between hydrostatic and colloid osmotic pressures, the existence of the latter being dependent upon relative impermeability of the capillary membrane to plasma proteins. Starling's concept has been verified by direct ...
متن کاملNeutral and DEAE dextrans as tracers for assessing lung microvascular barrier permeability and integrity.
Steady-state lymph-to-plasma concentration ratios (L/Ps) of neutral dextrans, cationic DEAE dextrans, and endogenous proteins were determined under normal and increased permeability conditions in six unanesthetized yearling sheep prepared with chronic lung lymph fistulas. Fluorescent dextrans with radii ranging from 1 to 30 nm were intravenously infused, and after 24 h, perilla ketone (PK) was ...
متن کاملThe serum viscosity and the serum proteins.
Equal weights of the various protein fractions in plasma affect the plasma specific gravity equally, whereas weight for weight the fractions exert differing influences on the plasma viscosity. Thus fibrinogen has a greater effect on the plasma viscosity than does globulin, which, in turn, has a greater effect than albumin (Bircher, 1921 ; Naegeli, 1931; Oberst, 1939; Cowan and Harkness, 1947). ...
متن کاملserum proteins, transaminases and phosphatases in malnutrition
the levels of serum tota1 protein, albumin, transaminases and phosphatases were estimated in a group of children with severe marasmus or mild malnutrition in order to identify some of the associated deficiencies in these syndromes. the biochemical pattern was similar in the normal and malnourished children.
