RELEASE OF 131I FROM THE OVARY OF THE LAYING JAPANESE QUAIL AFTER INJECTION OF PERCHLORATE, THIOCYANATE OR IODIDE

Abstract

SUMMARY Intramuscular injection of KSCN, KClO4 or KI into laying Japanese quail resulted in the discharge of 12·6 to 34·0% of the ovarian 131I within a 1-h measurement period for birds studied 1 to 6 h after labelling. Potassium thiocyanate was as effective as an equimolar quantity of KClO4 in causing this discharge. For birds studied 18 h after labelling, no consistent effect of KClO4, KSCN or KI on ovarian 131I levels was found. Gel, thin-layer and paper chromatography of labelled oocytes determined that > 92% of the 131I was present as inorganic iodide.
