Lower limits of cerebrovascular permeability to nonelectrolytes in the conscious rat

Abstract

I&c*. 2hyCL $3): H299-~3~1j 1978. -Vascular permeability P in different cerebral regions of the conscious rat was determined, independently of blood flow, for "C tracers of glycerol, mannitol, sucrose, and inulin. A tracer was injected intravenously, arterial plasma concentrations were monitored, and regional brain concentrations were measured at specific times thereafter.
