| Abstract: | The biosynthesis of 18-hydroxy-11-deoxycorticosterone (18-OH-DOC) was studied by in vitro incubations of human adrenals resected from patients with Cushing's syndrome, using deoxycorticosterone as precursor. 18-OH-DOC synthesis was similar in adrenals from normal subjects and in those derived from patients with different types of Cushing's syndrome (hyperplasia, adenoma, carcinoma). The in vitro addition of o,p'-DDD (5 x 10(-3) M) to an adrenocortical carcinoma incubation did not alter 18-OH-DOC biosynthesis. By contrast, treatment of the patient with o,p'-DDD prior to adrenalectomy resulted in a low production of 18-OH-DOC in vitro but only when cortisol synthesis was drastically decreased. |
