Concentration of radio-iodide and 35-S-thiocyanate by the salivary glands.

Logothetopoulos JH, Myant NB

J Physiol. 1956 Oct 29;134(1):189-94.

"It has recently been shown that iodide is concentrated by certain parts of the duct system of the hamster's salivary glands (Cohen, Logothetopoulos & Myant, 1955). We have now extended these observations to the salivary glands of mice and rats. Since thiocyanate is known to inhibit the concentration of iodide in the saliva (Freinkel & Ingbar, 1953; Rowlands, Edwards & Honour, 1953) we have also studied the concentration of 35S-labelled thiocyanate in the salivary glands." 

"1. Contact autoradiographs were made from freeze-dried sections of the salivary glands of hamsters, mice and rats after injections of radio-iodide and 35S-labelled thiocyanate.

2. Selective blackening was found over the proximal ducts of the submaxillary glands and the main ducts of the parotid glands of hamsters and mice. The pattern of blackening was similar after radio-iodide and 35S-thiocyanate.

3. Selective blackening was not observed over sections of the salivary glands of rats after radio-iodide.

4. Radio-iodide and 35S-thiocyanate were concentrated in the saliva and submaxillary glands of hamsters and mice, but not of rats."
