[Lipolysis in fatty tissue of patients with adrenohypercorticism]

Lipolytic activity was studied in subcutaneous and peripheric adipose tissue of patients with adrenohypercorticism (25 patients with Itsenko-Cushing disease and 4 patients with Cushing syndrome caused by corticosteroma of adrenal gland) and in 11 persons without this pathology. The lipolytic activity of the both adipose tissues in the patients with Itsenko-Cushing disease was similar to that of healthy persons and decreased in the patients with Cushing syndrome. The receptor-enzymatic system, responsible for lipolysis in adipose tissue, was not impaired in Itsenko-Cushing disease; differences found in lipolytic effects of corticotropin and somatotropin were caused by deteriorations in secretion of endogenous hormones in the disease. This system was inhibited in Cushing syndrome. Antilipolytic effect of insulin (especially in presence of glucose) was more distinct in subcutaneous adipose tissue of patients with Itsenko-Cushing disease as compared with controls.
