PENETRATION OF RADIOACTIVE SODIUM AND CHLORIDE INTO CEREBROSPINAL FLUID AND AQUEOUS HUMOR

Abstract

1. Experiments were performed on six dogs to determine the rate of penetration of Cl³³ and Na²⁴ across the blood-aqueous humor and blood-cerebrospinal fluid barriers after intravenous injection of the radioactive ions. The radioactivity measurements were made with an immersion type of Geiger-Müller counter.
