ERYTHROCYTES AS VOLUME MARKERS IN EXPERIMENTAL PD SHOW THAT ALBUMIN TRANSPORT IN THE EXTRACELLULAR SPACE DEPENDS ON PD FLUID OSMOLARITY

摘要

Background: Macromolecules, when used as intraperitoneal volume markers, have the disadvantage of leaking into the surrounding tissue. Therefore, Cr-51-labeled erythrocytes were evaluated as markers of intraperitoneal volume and used in combination with I-125-labeled bovine serum albumin to study albumin transport into peritoneal tissues in a rat model of peritoneal dialysis (PD).
