Abstract
We have studied the action of infusions of the various dried glands upon the volume of the pancreas. The animals used were etherized cats. The injections were made per jugular. The volume of the pancreas was registered with a modified piston recorder.
Infundibulin (pituitrin) causes a marked increase in the volume of the pancreas. Adrenalin produces a decrease in volume for a short time and then an increase. The pineal gland infusion increases the volume. Infusion of thyroid momentarily decreases and then increases the volume. Iodothyrin also increases the volume. Thymus does the same.
Secretin depresses blood-pressure for a short time and increases the volume of the pancreas to a marked extent.
Infusion of pancreas decreases the volume for a moment and then increases the volume of the pancreas. The renal cortex decreases the blood-pressure for a moment, but increases the volume of the pancreas to a marked extent.
Prostatic infusion had no effect on pancreatic volume. Tonsillar infusion lowered blood-pressure and slightly increased volume of pancreas.
Mammary gland infusion decreased blood-pressure for a short time but caused a marked increase in pancreatic volume.
Spleen infusion had no effect on volume of the gland. The same may be said for orchitic extract.
Parathyroid infusion decreases blood-pressure for a short time, also decreases pancreatic volume for a short period, and then greatly increases it.
Infusion of corpus luteum decreases blood-pressure momentarily and increases the volume of the pancreas.
Pineal infusion increases the flow of pancreatic juice.
