The cardio-active principle in spleen.

A substance has been demonstrated in acetone extracts of freeze-dried spleen which had cardiotonic properties on isolated papillary muscles from the cat and perfused hearts of the cat and guinea-pig. This activity of the extract could not be explained by the presence of choline, acetylcholine, histamine, 5-hydroxytryptamine, adrenaline or noradrenaline.
