EFFECT OF CORTISONE ON RAT THYROID

Abstract
In agreement with many other authors it was found that cortisone inhibits the rat thyroid. The percentage of the epithelium in 17 control cases was 66.8 [plus or minus] 2.8 and that of the colloid 21.3 [plus or minus] 2.4. In 33 cortisone injected cases the percentage of the epithelium fell to 52.0[plus or minus] 4.7 and that of the colloid rose to 36.3 [plus or minus] 6.2. Length of experimental period (12-78 days) did not affect the results.
