THE EXTRACELLULAR SPACE IN EXPERIMENTAL BRAIN TUMORS
Acta Neurologica Scandinavica, 1971Experimental brain tumors were produced in mice with 20–methyl cholanthrene, and the uptake of radioactive extracellular markers was studied by tissue assay and autoradiography. The tracers included C14-sucrose, C14-inulin, and H3inulin. The water content and isotope concentration of both gliomas and meningiomas were higher than those of normal brain ...

Inulin as an Indicator for the Extracellular Space
Acta Physiologica Scandinavica, 1946Summary.A number of results are quoted from the literature, showing that the available volumes for Cl‐and Na+are larger than the extracellular volume; the author gives a tabulated summary of literature references to the size of the available volume for these substances and the volumes of distribution for these and SCN‐, Br‐, SO–4, sucrose and Mg++.In ...

Distribution of the extracellular space of the amphibian lens
Experimental Eye Research, 1976Abstract The extracellular space of the amphibian lens, measured with [14C]inulin, was equivalent to 7% of the tissue water. In decapsulated lenses it was only 1·2% so that about 80% of the total extracellular space is located peripherally. The total [14C]mannitol space was larger (12%) though the capsular part was the same as that found using inulin.

It has been proposed that in the absence of blood supply, the ocular lens operates an internal microcirculation system that delivers nutrients to internalized fiber cells faster and more efficiently than would occur by passive diffusion alone.

EXTRACELLULAR SPACE IN THE CENTRAL NERVOUS SYSTEM
Archives of Neurology And Psychiatry, 1955A KNOWLEDGE of the volume and composition of the extracellular space in brain substance is of considerable importance in any investigation dealing with electrolyte concentrations in nerve tissue and with mechanisms of fluid shifts in cerebral edema. Although fluid partitions have been thoroughly studied in the body as a whole, and in muscle tissue in ...

Extracellular space diffusion and pathological states
2000Publisher Summary There is increasing evidence that long-term changes in the physical and chemical parameters of the extracellular space (ECS) accompany many physiological and pathological states. The acute or relatively fast changes in the size of the intercellular channels are apparently a consequence of cellular (particularly glial) swelling ...

Thiocyanate in the Brain and the Size of the Extracellular Space
1968Publisher Summary It is generally believed that Thiocyanate ions are mainly extracellular and the Thiocyanate space of tissues has therefore been equated with the extracellular space. The brains from animals with high plasma Thiocyanate concentrations were lighter than those from control animals. The dry weight varies very little and is unaffected by
