Abstract
1) Salivary glands of rats decreased in weight markedly with the administration of thiourea or potassium thiocyanate in drinking water for two weeks and this change was recovered with the intraperitoneal injection of adequate dose of L-thyroxine.
2) The effect of chronically partial sialoadenectomy on iodine metabolism of rat thyroid was studied, and no significant change was observed in 40 and 60days after operation.
