The relation between the calcium-lowering and lipid mobilizing effects of crude sheep pituitary extract given intravenously was investigated in rabbits. Pituitary extract produced hypocalcaemia and free fatty acid elevation in rabbits. The hypocalcaemic effect was not related to the lipolytic effect of the extract, since infusion of dextrose in water prevented the lipolytic effect without altering the hypocalcaemic effect of the pituitary extract.
