THE EFFECTS OF INTRACISTERNAL INJECTION OF SODIUM BROMIDE UPON THE BLOOD-SPINAL FLUID BARRIER

Abstract

Evidence is presented that intracisternal injns. of NaBr in amts. too small significantly to alter the serum bromide level lower the barrier to the passage of bromide ion into the spinal fluid. The distribution ratio of K and chloride ion is affected also by this procedure. Analysis of the spinal fluid after intracisternal injn. reveals that the fluid more closely resembles an ultrafiltrate of serum than before the injn.
