THE INFLUENCE OF DESICCATED SUPRARENAL CORTEX AND MEDULLA ON THE GROWTH AND MATURITY OF YOUNG RATS

Abstract
Growth of young rats is retarded by 0.5 gm. of either desiccated suprarenal cortex or medulla. Young 9 rats fed 0.5 gm. of desiccated suprarenal cortex reach sexual maturity sooner, as shown by earlier litters, than controls or those fed on 0.5 gm. of desiccated suprarenal medulla. The feeding of suprarenal medulla has little, if any, effect on the age of maturity in rats.
