Abstract

The problem of parathyroidectomy has been extensively studied in recent years. Greenwald (3) in (1925) provided the first satisfactory evidence of the effect of parathyroidectomy on the excretion of calcium and phosphrous. That retention of these elements follows the removal of the parathyroids glands has been confirmed repeatedly, but is less clearly established that this operation is capable of influencing the metabolism of other organic constituents of the body.

In one of his earlier experiments, Greenwald (1913) noted that primary retention of phosphorous was followed by a secondary decrease in the excretion of sodium and potassium in the urine.

The removal of the parathyroid tumors for therapeutic purposes seem to have many points in common with experimental parathyroidectomy in animals (Bueger, Dixon, Barr, and Schregardus (2) 1930) even on occasion being followed by severe tetany.

There have been no bad effects following parathyroidectomy in some cases unless the animal undergoes some special stress. This stress may be pregency, lacation, infection or an excessive meat diet when symptoms of tetany makes their appearance. In such cases there is usually a sufficient amount of accessory of parathyroid tissue which is thought to exist to protect the animal, under the ordinary circumstances of life. On the other hand, if there is not a sufficient amount of parathyroid tissue there is made a call upon the parathyroid harmone which is unable to be supplied.
