Abstract：
:The metabolism of the phospholipids of the submaxillary gland are studied after intraperitoneal injections of [32P]-orthophosphate in several groups of rats. The gland contains mainly phosphatidylcholines and phosphatidylethanolamines and in smaller quantities phosphatidylinositols, phosphatidylserines, sphingomyelins, polyglycerophosphatides, lysophosphatidylcholines and phosphatidic acids. The specific activities of the phospholipids measured in relation to the time (1/2 hour, 1, 2 and 3 hours) show a strong incorporation in the phosphatidylinositols then in the phosphatidylcholines. The other phospholipids have lower activities. The specific activities of the phospholipids measured one hour after injection of different pharmacodynamic agents show the phosphatidylinositols, phosphatidylcholines, sphingomyelins and lysophosphatidylcholines are altered. Acetylcholine increases their turnover, Atropine reduces it, and the addition of atropine counteracts the effect of acetylcholine in all these phospholipids.
