Brain interstitial fluid collected through implanted tissue cages.
The physicochemical properties of the whole-brain interstitial fluid (IF) are unknown. A volume of whole-brain IF sufficient for analysis was obtained through a small, hollow, multiperforated polypropylene sphere implanted for 4-5 weeks into the dog brain parenchyma. The main physicochemical properties of the whole-brain IF were characterized, in comparison with the physicochemical properties of cerebrospinal fluid and blood/serum.
