In the rat, renal compensatory hypertrophy (RCH) is enhanced by the administration of ACTH (beta 1-24 corticotrophin) given at a dose of 18 micrograms/100 g. body weight/d. after uninephrectomy. In the rats drinking tap water, the enhancement of RCH by ACTH occurs without any significant change in urinary Na+ excretion. But, in the animals drinking a NaCl solution (9 g/l), ACTH determines a polyuria with hypernatriuria and a more striking increase of RCH positively correlated with the urinary Na+ excretion.
