When rats are maintained on liquid diet for a period varying from 4 to 21 days the parotid but not the submaxillary and sublingual glands are reduced in weight. Although the weight decrease is profound the response of the parotid to sialagogue agents and the maximal secretory capacity are the same as those of the control gland, except for a slightly smaller response to adrenaline. The synthesis of acetylcholine in the parotid gland, judged by the activity of choline acetyltransferase, is lowered after only 4 days. The result seems to indicate that the synthesis of transmitter is dependent on the secretory impulses to the gland.
